Catco Instrument Gas Heaters use a catalytic heater to direct infrared heat at a stainless steel heat exchange tube inside an enclosure. The infrared heat warms the tube, which in turn warms the gas, air, or other fluid that is flowing through it.
The Catco Instrument Gas Heater is commonly used to preheat instrument gas or instrument air streams for pilot operated regulators, valves, and other equipment.
