Crowcon Xsafe

Crowcon Xsafe Gas Detector

The Crowcon Xsafe is designed for easy installation and maintenance – keeps costs down. There are three junction box options designed to make replacement of sensors and sinters extremely simple. Spare sensors simply plug-in. Many spare parts are common to all Xgard models – keeps spares holding requirements to a minimum. The Xsafe is available for either wall or ceiling mounting – no need for additional brackets. The unit can accommodate M20, 1/2″ NPT or 3/4″ NPT cable glands – suits all site requirements. Accessories are available for duct mounting and sampling applications as well as remote gassing.

Manufactured using a choice of three materials: glass reinforced nylon, highly durable aluminium with a tough polyester coating, or 316 stainless steel for ultimate corrosion resistance – designed to operate even in the harshest environments
Spray deflectors and weatherproof caps are available for use in areas subject to regular wash-downs, or offshore environments. All models have been validated to the functional safety standard IEC 61508 (SIL 1 to SIL 3).
