Instrument Gas Heaters

In Catco Instrument Gas Heaters, stainless-steel heat exchange tubes pass in front of a catalytic heater to raise the temperature of the gas, air, or other fluid flowing through it. They’re most commonly used to heat the gas flowing to the pilot of a pilot-operated regulator or valve, but can be used in any application where a gas stream needs to be warmed.

How They Work

Catco catalytic heaters bring fuel and oxygen together in the presence of a heated catalyst. This causes a chemical reaction that produces infrared heat but no flame, and the catalyst is not consumed by the reaction. Once it’s operational, a catalytic heater can operate indefinitely if it has a clean source of fuel and sufficient air. The operating characteristics of Catco catalytic heaters have made them a safe and effective solution in a variety of industrial applications for decades. They are particularly well suited for use in hazardous areas and remote locations. Catco catalytic heaters can be configured with certification by FM or CSA for use in Class I, Division 1 & 2, Group D areas.
