Electrical Resistance Heat

For non-hazardous/explosive locations: Built-in 5 KW or 10 KW corrosion-resistant incoloy tubular electric heating elements (does not change overall dimensions).

For hazardous/explosive locations: Built-in 5 KW or 10 KW corrosion-resistant fin-tubed electric heating elements rated T3B (does not change overall dimensions).


Isolate thermostat to restrict adjustment by authorized personnel to reduce the wear and tear on the equipment caused by frequent or inappropriate adjustments in the temperature settings. All thermostats have stainless-steel bulbs and capillary tubes.


Scroll compressors are standard; reciprocating compressors are an option on most models.

Movement and Vibration

Adaptation for use on vehicles (cranes, workboats, mining equipment and military vehicles) and other applications with vibration or other types of movement.

Hazardous (Flammable and Explosive) Locations

Modify equipment to make it suitable to various types of hazardous (flammable or explosive) environments.
