Indicators and controllers provide explosion protection
Mike Edwards
Products Alpha Controls & Instrumentation controllers indicators purgePurgEx Z, Y, and X purge indicators/controllers from Alpha Controls & Instrumentation are purged and pressurized systems that provide a method of explosion protection where components internal to the enclosure cannot be specifically rated for the area.
The components provide a light weight, corrosion resistant alternative to traditional explosion proof enclosure.
The protection concept maintains an above atmospheric pressure within the enclosure not allowing hazardous gas and/or dust from entering and coming into contact with possible sources of ignition.
Stainless steel or anodized aluminum construction is rated to NEMA 4 or 4X.
Systems are certified to ATEX/IECEx/NEC/CEC in a single part number. Dry contact outputs for remote monitoring comes standard.
