PROCESS AIR HEATERS
Installed
in forced air ducts, these units supply constant heat for industrial
processes requiring air temperatures up to 750°F / 400°C.
Construction features include heavy gauge mounting flange, insulated
terminal enclosure and easily replaced heating elements. Typical
uses include forced air dryers, core drying, heat treating, annealing
and other high temperature applications.
Options:
 Special ratings and/or sizes
Moisture resistant/explosion resistant terminal enclosure
All stainless steel frame construction
Thermowell
Replacement element part number J4W-0110
Thermocouple welded to sheath for high-limit protection
Solid State controls/control panels. |
Guidelines:
Maximum Sheath Temperature: 1150°F/620°C
Maximum Outlet Air Temperature: The guideline
is based on 22 watts per square inch.
 |
Unit should not be energized in
air with a velocity less than 60FPM.

HIGH TEMPERATURE PROCESS AIR HEATERS
High Temperature
Process Air Heaters provide process temperatures up to 1200°F
/ 650°C for many oven and forced air applications. Typical
applications are recirculating ovens, converting ovens from gas
or oil combustion, drying or curing ovens, heat treating, annealing
and dehumidification.
