CO2-HEATER - Profax 120V Electric CO2 Regulator Heater, 100W

Reliable Thermal Management for CO2 Shielding Gas

The Profax Electric CO2 Heater is an essential component for industrial welding operations utilizing Carbon Dioxide (CO2) as a shielding gas. When CO2 is released from a high-pressure cylinder, it undergoes rapid expansion, resulting in a significant temperature drop due to the Joule-Thomson effect. In high-flow applications or cold environments, this adiabatic cooling can cause the regulator or flowmeter to freeze, blocking gas flow and compromising weld integrity. The Profax CO2-HEATER addresses this thermodynamic challenge by pre-heating the gas stream directly at the source.

Engineered for efficiency and reliability, this unit operates on a standard 120 VAC / 60 Hz power supply and utilizes a 100-watt heating element. It features an integrated thermostat that automatically regulates the temperature, ensuring the gas remains warm enough to prevent freezing without overheating the equipment. The heater is designed to be installed inline, positioned securely between the cylinder valve and the regulator. This placement ensures maximum heat transfer efficiency before the gas expands into the regulator body.

By maintaining a consistent gas temperature, the Profax heater prevents the formation of dry ice crystals within the regulator mechanism. This protection is vital not only for maintaining continuous workflow but also for extending the operational lifespan of sensitive regulation equipment. Sudden pressure spikes and mechanical stress caused by freezing and thawing cycles are eliminated, protecting your investment in high-quality flowmeters and regulators.

This unit is compatible with standard CO2 cylinder connections and is built to withstand the rigors of industrial environments. It is a preventative maintenance tool that ensures process stability, particularly in high-duty-cycle MIG welding applications where consistent gas coverage is non-negotiable.
