Thermostat

A thermostat simply switches the heating system on and off as necessary. It works by sensing the air temperature, switching on the heating system when the air temperature has been quickly reached.

Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system for example the size of the boiler and radiators. Neither does the setting affect how quickly the room cools down. Turning a room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.

The heating system will not work if a time switch or programmer has switched it off. The way to set and use your room thermostat is to find the lowest temperature setting that you are comfortable with, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18ºC – and then turn it up by one degree each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money.

Room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture.

STRIP HEATERS

dpstar is a manufacturer and one of the biggest supplier of strip heaters in Malaysia.

Strip heaters are used principally for convection-type air heating and clamp on installation. It is an excellent industrial heating product that can be easily controlled by using a temperature controller or a mechanical thermostat that can be installed on the surface you are heating. When selecting strip heaters two important factors must be considered: the proper sheath material for resisting any rusting and oxidizing inherent in the process environment and for withstanding the sheath temperature require.

Mounting holes are useful to mount the process heaters securely on almost any surface with terminal extending from the sheath for easy electrical connections. Many users also request lead wires that extend from one end that make the installation more flexible as the temperature control panel is easily adaptable to this configuration.

Temperatures as high as 250 Celsius can be reached and that allow for effective heat transfer. A fairly inexpensive way of heating surfaces or small areas, strip heaters are an excellent solution to meet any budget. Strip heaters are composed of a heating element, a protective sleeve or sheath, and mounting hardware. If strip heaters are used as a radiant heater, they have can have fins to maximize surface area and heat transfer to the air. Strip heaters can be clamped or bolted onto objects or solid surface contact heating over large areas and are primarily used in indoor applications.

dpstar also manufactures other industrial heating products i.e. immersion heaters, infrapara heaters, ceramic heaters and etc. Click here to view our products.

Industrial Heater

Types for Electric Heaters for Direct Heating

Direct Heating
dpstar  manufactures and supplies various types of industrial heaters.
Direct heating, as the name implies, is a heating method in which the heater is directly immersed into the medium to be heated (it can be liquid or gas, depending on the industrial process). This is the most efficient method of heating, as there is no thermal lag or heat transfer losses. Plus, the method is also considered as more energy efficient and precise than indirect heating because the heat generated in this process by the electric heater is immediately absorbed in the fluid. However, mounting styles and temperature control vary with the type of electric heater.

Indirect Heating
Indirect heating is based on the basic principle of heat transfer from the hotter medium to the colder one. The method does not use electric heaters directly. The fluid to be heated is usually stored in a heating tank, and external heat is applied. The method usually uses heating pipes and boilers to heat the fluid.

• Immersion Heaters

Immersion electric heaters consist of a mechanical thermostat and digital sensors to heat the fluid to the desired temperature. These heaters are called immersion heaters because the heating element is directly immersed into the fluid to be heated. However, the design of immersion heaters depends on the wattage rating and area of application.

• For small reservoirs, screw immersion heaters are used.
• For medium to large-sized tanks, flanged heaters are used.
• For tanks without openings, over-the-side immersion heaters are used.
• Circulation Heaters

Circulation heaters are also electric industrial heaters used to heat viscous fluids. The heating element in circulation heaters keeps on regulating, which facilitates for heat transfers through dense fluids. They are preferred over immersion heaters in applications with space limitations, as these heaters can be directly installed in the heating tank.

• Suction Heaters

The heavy fuel industry uses electric suction heaters to heat viscous oils and gases. These heaters consist of a flanged heating element immersed into the heating tank while the other end of the heater is open. The fluid pumped from the tank can be heated directly. These heaters eliminate the need of an additional storage tank.
Now that you now the various types of electric heaters used in industrial heating, keep technical factors and heating requirements in mind to choose the right type of industrial electric heater.

Float Switch/Level Switch

The purpose of a float or level switch is to detect and control the level of rises or falls of a liquid in a tank.
Most float switches are the type that just open or close a circuit as the level of liquid in a tank rises or falls. With the more common reed switch, the device will have two electrical contacts sealed in a glass casing. The two leads will be close within the housing, but they will not be touching. The housing with the glass leads will be mounted at a point in the tank to determine the liquid level that triggers the response. In the liquid, you then have a magnetic float. As the level of the liquid in the tank rises or falls, the float will come closer to the leads. When the float is in range, the leads become magnetized and then come together, completing the circuit. When the liquid level changes in a way that brings the float away from the electrical contacts, they separate and the circuit is broken.

An example would be a float that rises with the liquid to trigger a switch that turns on a pump. When the pump has removed enough of the liquid, it can then disengage the pump. Conversely, a float could be configured to float in liquid that needs to maintain a certain level. As the level drops, the float will eventually come in range of the switch. This could then trigger the opening of a valve to refill the tank to a predetermined level.

These are just a few of the more simple functions that a float switch can perform. Depending on the purpose and the design of the switch, they can be applied to much more complex tasks. Understanding the desired application of the switch will help to determine the right type of float switch that should be used and the configuration.
We at dpstar Manufacture and design various type of Maltec Float Switches or Maltec Level Switches.

Immersion Heater: Simple Calculation

Electricity is measured in kilowatt hours (or kWh). A kWh is a unit of energy equivalent to one kW of power expended for one hour.In some cases, people heat their water with electricity – normally through the use of electric immersion heaters – that act like huge like kettles. We often get asked whether these are expensive to run, so the following should help you work that out for yourselves!

·         How many KW of electricity are needed to heat a hot water tank?
So the two bits of information you are going to need to help calculate this are the size of the tank measured in litres and the required temperature rise.
The required temperature rise (measured in centigrade) is calculated by taking the starting temp of your cold water from the hot water temperature required. For example if your water is 100C and you want to heat it up to 600C, then the temperature rise would be 500C.
The following formula can then be used to calculate the power (in kW) needed to heat a specific volume of water by a given temperature in 1 hour.

·         Volume of tank x 4 x temperature rise / 3412 = Power required
So if the tank is 125 litres and you want to take the water up to 650C from 100C, then it would simply be:
125 x 4 x 55 / 3412 = 8kW
This means that you would need 8kW of electricity to heat this volume of water up in 1 hour. If you wanted to heat it up in 30 mins you would need 16kW of power and so forth.

·         Immersion heaters are measured in kW
When you buy an immersion heaterit is given a kW rating, so for example 3kW or 6kW.
If you take the above example and have a 3kW immersion heater it would take about 2hrs 30min to heat the water (3kW each hour, so in two and a half hours that would give 7.5kW).

·         Cost of running an immersion heater
The cost of electricity is about 14 sen/kWh, which means that it would cost about 45 sen to run a 3kW immersion heater for an hour.
Normally though the immersion will turn on and off via the thermostat or a temperature controller so the amount of time they are on fluctuates, depending on the existing temperature of the water in the hot water tank.

dpstar Group is the largest manufacturer of Heaters and Thermocouples in Malaysia.

Silicone Drum heater

Many materials become viscous at room temperature, notably sugars, syrups, fats, lubricants and a variety of chemicals. Without heating, product typically cannot be discharged quickly from a drum into the production process, even at room temperature. Heating the drum, or other container type, provides a practical and effective method for maintaining process efficiency, by allowing faster decant of ingredients at all times and in all environments

Raising the ambient temperature to improve production efficiency is a costly and often impractical process. Effective drum and barrel heaters eliminate waste and lower costs that arise from damaged materials caused by improper storage. A further advantage of heating drums is a better product yield. Without heating, many contents cannot be fully discharged due to their viscosity, leaving waste product in the container which can add significantly to manufacturing costs.

Maltec Drum Heaters and base heaters can thus deliver valuable advantages to the manufacturing process, with reduced waste and shorter production cycle times.

Applications:

ü  Melt or preheat process ingredients

ü  Heat drum contents to required temperature

ü  Control viscosity for handling processes

ü  Heat drums to protect against freezing

ü  Speed flow of liquids with a drum heater

ü  Maintain liquid temperatures in water purification systems

ü  Use oil drum heaters to raise and maintain temperature during biodiesel production.

CIRCULATION HEATER

Maltec Circulation Heaters are made with stainless steel because of its anti-corrosive qualities. The application involve using a pump that flows the liquid through a closed pipe circuit (IE. water or glycol solution) that is reheated. A major consideration for this application is viscosity. Heat that is generated by the electric heater allows the liquid to be viscous enough to pass through the circuit of pipes. Circulation heaters come in a range of watt densities that are specifically designed for the medium that is heated. The required wattage to heat the oil or water is highly correlated to the flow rate (in GPM). The oil or water enters through an inlet (the inlet closest to the flange heater) and gets heat applied to it as it flows within a vessel chamber and exits the outlet nozzle (or flange) where it circulates throughout the piping circuit. Insulation is often required for vessels in order to preserve the heat to be applied within the vessel. Efficient heat application can often reduce unnecessary costs through heat loss. Thermocouple probes or RTDs, can be used with the electric heaters to maintain the oil or water at the preferred temperature.

Other useful features found with electric circulation heaters are drain valves. They can be installed in any location on the vessel and allow for easy maintenance of the heater. The water or oil can be purged through the drain valve allowing for maintenance on the elements. Calcium deposits and other residue can be found on elements and should be cleaned several times a month. Circulation heaters also come with the choice of horizontal or vertical mounting depending on your application. 

Maltec Circulation Heaters are also available in moisture resistant terminal boxes for hazardous environments and it is an exceptional choice for heating process liquids, non-corrosive to the materials of construction.

Oil and Gas companies have specifically used circulation heaters to assist them in the process of modifying viscosity levels of their heating oils. Crude oil enters an inlet of the vessel at a cool temperature and exits the outlet at a temperature more convenient for flow as it travels from one end of the transport pipe to the other. Hydraulic fluid can also be heated using this electric heater for heat transfer purposes, and to resist cooler climates. Immersion heaters are widely used in a variety of industries particularly the oil and pipeline sector for several different purposes. These industrial heaters are specifically designed so that oil, water, viscous materials, gases, solvents and other different process mixtures can be heated in direct contact with each other. This allows the heat to be generated within a single enclosure or solution and optimum efficiency can be achieved.

Thermowell

Thermowell is use to protect temperature sensors such as thermocouples, thermistors and bimetal thermometers against damage from excessive pressure and corrosion installed in industrial processes. Maltec-H Thermowell is basically a hollow metal tube with one end sealed and it is usually mounted permanently in a vessel or pipe work. The sensor is inserted into it and makes contact with the sealed end.

They also increase the longevity of the sensor, allow sensor replacement without draining the system and reduce the probability of contamination.

A simple diagram showing a thermowell in use with a temperature gauge.

Thermowells are categorized according to the design of the stem. A straight thermowell is the same diameter throughout the entire insertion length and offers protection against corrosion and erosion. Stepped thermowells usually have a ¾” diameter at the top which is reduced to ½” diameter near the tip. The reduced surface area allows smoother velocities and faster temperature response for sensing devices. Tapered thermowells have a diameter that decreases gradually over the length of the insertion length. They offer superior strength as well as fast response times to temperature changes. Tapered thermowells are most often used in high velocity applications. Case studies performed on straight and tapered thermowells used in natural gas pipelines found that straight thermocouples experienced premature failure when exposed to flow induced vibrations.

dpstar manufactures and supplies various type of thermowells.

Heating Elements

Most equipment or machinery that require heat to perform their processes use a heating element of one kind or another. Furnaces, heating process lines, oven dryers, water heaters, and other machine makers approach dpstar’s Maltec H range of manufactured heating elements for their heating requirements. The amount and wideness of the our customer base who purchase such heaters for their process application is almost uncountable. For example one of our biggest markets is in the packaging industry where these players use applications such as plastic fabricating, foam fabricating, metal fabricating and food processing industries, cartridge heaters are inserted into the machine where the heating is required. Immersion heaters and tubular heaters are used when the application required the heat to be transferred into liquid or air in industrial drying ovens, storage tanks for temperature control, pressure vessel heating, steam generation, furnace and boilers, water treatment facilities and many other applications. For instance, immersion heater elements are required when a process such as food manufacturing or drinks production takes place.

dpstar makes such heating elements and through our wealth of experience, we have been a renowned supplier and manufacturer of these heaters in the Malaysia market.

Heating

Heating requirements are critical in many different processes in the manufacturing industry, to fulfil such requirements heating elements are used heavily because they can be shaped and customised to different size, specification, configuration. The option to change different materials allows for most applications across different industries. But the fundamentals remain the same, these heaters convert electrical energy to heating energy and the heat is disbursed through contact with air, liquid, and solids.

Since the heaters allow for flexibility, many will find them being used in infrared heaters, flexible heaters, quartz heater’s just to name a few. All these heaters can be found in industrial or commercial application whether to control or maintain a certain temperature. The most widely used heating element today, also one of dpstar’s mainly supplied and distributed heater in Malaysia is tubular heaters, they can be found on kitchen stovetops and dishwashers. While other heating elements can be seen in industrial and commercial application in kilns, tanks, and drying ovens.

dpstar’sheating elements is produced under our trademark Maltec-H brand, we are one ofthe largest makers and suppliers of such heaters in Malaysia and South-eastAsia. 

RTD – Resistance Temperature Detector

An RTD ( resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between an RTD’s resistance and the surrounding temperature is highly predictable, allowing for accurate and consistent temperature measurement. By supplying an RTD with a constant current and measuring the resulting voltage drop across the resistor, the RTD’s resistance can be calculated, and the temperature can be determined.

Different materials used in the construction of RTDs offer a different relationship between resistance and temperature. Temperature sensitive materials used in the construction of RTDs include platinum, nickel, and copper; platinum being the most commonly used. Important characteristics of an RTD include the temperature coefficient of resistance (TCR), the nominal resistance at 0 degrees Celsius, and the tolerance classes. The TCR determines the relationship between the resistance and the temperature. There are no limits to the TCR that is achievable, but the most common industry standard is the platinum 3850 ppm/K. This means that the resistance of the sensor will increase 0.385 ohms per one degree Celsius increase in temperature. The nominal resistance of the sensor is the resistance that the sensor will have at 0 degrees Celsius. Although almost any value can be achieved for nominal resistance, the most common is the platinum 100 ohm (Pt100). Finally, the tolerance class determines the accuracy of the sensor, usually specified at the nominal point of 0 degrees Celsius. There are different industry standards that have been set for accuracy including the ASTM and the European DIN. Using the values of TCR, nominal resistance, and tolerance, the functional characteristics of the sensor are defined.

dpstar manufactures Maltec-RTDs for many industrial applications. From single- or dual-element RTDs to Pt100’s we have the right sensor They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.
