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.

Quartz infrapara heaters

dpstar manufacures Quartz Infrapara Heater under the brand name Maltec-H
Quartz Infrapara heaters are specially designed for applications that require infrared radiant heating. Quartz Infrapara consist of a helically wound resistance coil housed in a pure vitreous silica fused quartz tube. The ceramic caps are securely fastened to the quartz tube with high temperature cement providing excellent support to the power connecting termination.
It is one of the most efficient sources of radiant energy and it does not give off an objectionable glare because of a very low emission in the spectrum.
Optimum design provides a clear red color on the translucent quartz tube when operating at full voltage, providing an infrared wavelength at energy peak of 2.5 to 30 microns.
The wavelength is almost completely absorbed by the process, and considered best for most industrial applications:

Advantages of Quartz infrapara heaters:-

• Clean heat energy
• Quick heat and cool down response
• Lower power consumption
• Functional design

Application:-

• Food Processing
• Food Warming
• Shrink Packaging
• Paint Curing and Drying
• Sterilization
• Thermal Copying Equipment

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.
