PRODUCT DESCRIPTION


Temperature Control Panels for a wide variety of applications are designed and engineered by National Plastic Heater. Entire systems are available for the most complex process heating control applications that require electric heaters, temperature controls, and temperature sensors. Panels can be built with as little as one zone to as many as 36 or even more temperature control points

 

In house calibration and servicing provides a full, single source for all your requirements. From Custom Temperature Control Panels that are needed to operate in 60șC environments, to laboratory controllers that are to maintain temperatures within +/- 0.01șC.

 

These Custom Temperature Control Panels, or Power Panels could be made to withstand wash downs with corrosive chemicals with all components on the panel conforming to IP 65 and NEMA 4X. Integration of components for steam booster heaters or recirculation heaters with flow fail safe interlocks are also available.

 

Applications include temperature controls with Hi temperature fail-safe alarms (FM approved), Loop break alarms, Heater break alarms, heater Current Indication and Shorted Output Device (contactor) alarms or annunciation.

Our industrial process electric heaters...

Our industrial process electric heaters consist of the following product categories: flanged immersion heaters, screw-plug immersion heaters, over-the-side heaters, circulation heaters, duct or air process heaters, pipe insert heaters, tubular heaters , finned tubular heaters and Temperature Control Power Panels.

Industrial process heaters are available with adjustable thermostats, digital temperature controls; SCR, mercury relay or mechanical temperature control power panels with process and high limit thermocouples.

Industrial process heaters from National Plastic Heater, Sensor and Control Inc. are Hydro approved and CSA or C UL recognized. Terminal enclosures can be NEMA 1 (General Purpose), NEMA 4, ( Moisture resistant) NEMA 4X (Corrosion/Moisture Resistant), NEMA 7 (explosion proof) and NEMA 12 (Dust and Oil Resistant).

Industrial heater sheath materials like Titanium, Incoloy, Stainless Steel, Steel, and Copper can be used as required for specific applications. Standard Flanged Immersion Heaters have a 150 lbs flanges but 300, 600 and 1500 lbs flanges are also available.

Below a brief description of most of our industrial process heaters line-up:

Screw plug immersion heaters consist of hairpin bent tubular elements brazed or welded into a screw plug and provided with terminal boxes for electrical connections.

Screw plug immersion heaters are screwed directly through a threaded opening in a tank wall or through matching pipe coupling, half coupling or welding flange.

Circulation Heaters offer the following: High efficiency heat transfer, Pressure ratings to 600 lbs, ANSI Standard NPT or ANSI Class 150 connections, Heaters could be screw plug or flanged, Stainless steel construction with Canadian Vessel Registration, Various housing options available NEMA 4, 4X, explosion proof,

Suitable for steam, oils, chemicals, gases, corrosive solutions.

Heating using pipe insert heaters: A pipe insert heater uses an element inserted into a sealed pipe. The advantage to the pipe insert heater is that the element is isolated from the process. This allows the element to be removed without draining the tank, isolates hazardous or corrosive materials from deteriorating the element, and if sized properly may allow the heat to be distributed over a larger surface area reducing the watt density exposed to the process.

Over-the-side immersion heaters are designed for vessels where through the side immersion heaters cannot be conveniently installed. These heaters are installed through the top of the vessel with the heated portion of the unit along the side or at the bottom of the tank.

NPH Tubular heaters can be used in their straight form or bent into various shapes.

Tubular heaters can be used in free air, clamped to a surface, placed inside a groove or cast into metal.

Finned tubular heaters offer distinct advantages over open coil heaters: (a) they are safer to operate in that the risk of fire or electrical shock are minimized; (b) they have a much longer service life; and (c) they are more rugged requiring less maintenance than open coil heaters.

Duct heaters from National Plastic Heater are composed of, tubular, finned tubular or open coil heating elements that are either flanged or inserted in the duct. Duct air heaters are generally an assembly of tubular heating elements ready to mount into a duct but it can also be an open-coil resistance wire assembly mounted into a duct.

Temperature Control Power Panels, for a wide variety of applications are designed and engineered by National Plastic Heater, Sensor and Control Inc. Entire systems are available for the most complex process heating control applications that require electric heaters, temperature controls, and temperature sensors. Control power panels can be built with as little as one zone to as many as 36 or even more temperature control sensing points.
