IMAC Systems Pilot Gas Preheater (Catalytic)

The IMAC Systems pilot gas heater applies direct, radiant heat to a stream of gas that flows through a serpentine heater exchange tube. The unit utilizes a Cata-Dyne explosion-proof pad. The gas runs through the tubing in front of the catalytic heater, maximizing surface area to increase the temperature of the gas.

Pilot Gas Heater

Avoid costly and dangerous shutdowns by using radiant heat to prevent freezing and hydrate formations in gas pressure reduction locations. Protect instrument supply gas for valve actuation, pilot-operated regulators, controls, and instrument regulators.
