The Cooling Air Harness provides critical cooling air for personnel wearing disposable suits in hot environments.  Typically used in nuclear power generation stations, coal-fired plants, etc. The IH Regulator (CAH-ACA) is inserted between the existing hose connection and the suit inlet component of the ACA

The product is terminated with a Hansen® 2RL Male Air Connector paired with an optional Cannon® XLR3 electrical connector.  The Cooling Air Harness is secured by elasticized straps – no modification is required to the disposable suit (No modification is required).

In the wake of Fukushima’s meltdowns, a group of nuclear safety personnel brainstormed a solution for further protection in the event of a meltdown or “High Alert” situation.  In a typical nuclear operation, the reusable Mark 3B Air Distribution Suit is worn for protection, cooling and air.  This new Auxiliary Cooling Harness augments the Mark 3B suit cooling function.  It works in the same way; however, the application is for Extreme Environments such as High Heat, High Stress and High Alert situations.

The CAH-02 enhances the existing cooling of the M3B suit system that provides protection to personnel working in radioactively contaminated environments typical of nuclear-generating stations.
