• INCOLOY

The large variety of ratings, sizes, materials and terminations makes the tubular heater useful for many industrial, commercial and scientific applications. If the resistance and the surface load are not exceeded, it can endure all wattages and voltages are possible.

Suction heaters are specifically designed to heat only that amount of material that is to be pumped from a large storage tank. The outlet nozzle is attached to the pump suction. The heater heats the material inside the heater pipe body which is then drawn through the heater into the suction side of the pump. This technique saves substantial energy costs since it is not necessary to heat the entire contents of the tank to draw off relatively small amounts of viscous materials. Complete weather-proof construction makes these heaters perfect for installation in large outdoor storage tanks. Large heater inlet provides smooth, full-flow through the heater.

Features

• Terminal enclosure: circulation heaters are designed to be installed outdoors in exposed areas. Enclosures are designed to be moisture resistant or moisture and explosion resistant. Low watt density elements make the heaters safe to use on most viscous liquids. Carbonization is minimized.
• Vessel: heater and mounting flanges are ansi b16. 5 150 lb carbon steel. Assembly provided with thermal insulation & outer metal sheath covering
• Thermostats/ temperature controls and control panels: they are provided with temperature controls to control fluid outlet temperatures and limit internal temperatures under abnormal depending on customer specifications. They may be supplied with factory equipped ar thermostats / temperature sensors in case of digital temperature controllers other panel accessories. Integral or remote mounted control panels with electronic controls and solid state (ssr) or contactor power controllers can be provided using virtually any combination of control devices.

This type of cartridge heaters comes in a wide variety with specific applications with low watt density. Some of the features exhibited by these heaters are as follows:

• Dual-voltage
• Three phase
• Ground terminal & different termination styles
• Voltage as low as 12 or 24 Volts is allowed
• Braided Wire
• Straight or right angle exit
• Max temperature for SS tube 400 °C, for Brass tubes 200 °C
• Diameters: Min 8mm to Max 45mm
• Length can vary
• Choice of lead lengths

It finds application in many industry processes, some of which are:

• Plastic molding
• Packaging equipment
• Heating tanks
• Plastic extruder's
• Labeling machinery
• Gas and liquid heating

Matrusree electro heats manufactures standard and custom electric immersion heaters in either a flanged, screw plug or custom flanged design. It consists of a single or multiple heating elements and can be used for a variety of fluid heating applications. However it is important to note that allowable watt density depends on the material being heated. The heating Eelement are hair pin bent and are either brazed or welded to the mounting attachment depending upon the element sheath material.

Matrusree drum heaters are used to pre-heat liquids in drums or pails to make them less viscous and more flow able. They are suitable heat sources when heat is required to handle liquids during pouring, dipping, coating or mixing operations. Matrusree drum heaters are made to brace a drum externally and they are easily installed and removed when needed.

Design Features:

• Stainless steel case
• Adjustable heat
• Easy installation and removal
• Suitable for standard drum sizes
• 6 ft power cord and plug
• CSA certified
• Rapid heat-up of drum
• Durable metal design
• Infinite switch or thermostat
• 3-heat control
• 6 ft. power cord
• Variety of sizes and ratings

Construction:

Matrusree drum heaters have a rugged construction, made to withstand the harsh industrial  environment. They are available in two styles. The one piece construction heater that comes with a spring loaded handle and a snap action bi-metal temperature controller (220° F). The HDX model is a two piece construction heater that has a latch and trunion fastener with a bulb and capillary thermostat (250° F).

Temperature Control:

Thermostat Control models sense temperature in an area remote from the heating element and will automatically cycle heater to maintain set temperature. Three-heat switch allows three wattage ratings per thermostat setting and voltage rating.

Mayrusree Drum Heater comes with temperature controllers. When the pilot lamp is on, the heater is Active. Our models have bulb and capillary thermostats (250° F). Another models have snap action bimetal temperature controllers (220° F). After an initial trial these controllers have to be set in proportion to the maximum settings and required temperature.

ELECTRICAL RATING:

Matrusree Drum heaters are made for 120V or 240V power supplies. Appropriate power cords and plugs are supplied for each voltage and wattage. The power supply should be rated to handle the amperage drawn by the heater. Different liquids absorb heat at different rates so the wattage of a Drum heater  should be selected accordingly.

MAINTENANCE:

Since the Matrusree drum heater  is not a sealed product, it should be used indoors and kept away from moisture and contamination. In general, these heaters are maintenance free. A periodic check to ensure that they are securely fastened to the drum is recommended. The power cord is rated to withstand 220° F and should never come in contact with the heater.

WARNING:

Matrusree drum heaters  should not be used on pressure tight containers, containers with explosive materials, or in explosive environments.

    Matrusree designs & manufactures variety of band heaters, That are most commonly used in the plastic injection moulding and extrusion processes machines. Use as low a watt density rating as your application permits. A close match of the heat supplied to the actual requirements will reduce temperature overshoot, reduce cycling and increase the life of any band heater you use.

Four basic Band Heater constructions are illustrated here

• Mica Band & Nozzle Heaters
• Ceramic Band Heaters
• “ Insulation Tech” Power Saving Heater
• Air-Cooled Ceramic Band with blower Jacket

Mica Band & Nozzle Heaters:

Matrusree’s mica band is a proven heater design for good life efficiency and dependability. It assures maintaining the lowest winding temperatures possible, keeping a low-mass heating element assembly for fast heat-up and quick response to controls.

Construction:

A specific, nichrome or kanthal ribbon wire is wound on specially selected mica grade providing even heat distribution for maximum heater life. Mica of proper thickness is then used to insulate the windings that provide excellent thermal conductivity and dielectric strength .The element pad is now enclosed in a specially treated rust-resistant steel sheath casing that provides the best combination of physical strength, high emissivity and good thermal conductivity to heated cylindrical parts.
