£2,108.00
The nVent HOFFMAN PCFF1YZ is a flush-mounted continuous flow purge and pressurisation system designed to help protect electrical and electronic equipment installed in hazardous locations. Using a controlled supply of clean, dry air or inert gas, the system purges potentially hazardous gases from an enclosure and maintains positive internal pressure to help prevent the surrounding hazardous atmosphere from entering.
Designed for Type Y and Type Z pressurisation applications, the PCFF1YZ provides continuous protective gas flow for hazardous-area enclosure installations. Its flush-mounted configuration provides a neat, integrated installation while retaining access to system indication and controls from the enclosure exterior.
The PCFF1YZ uses a protective supply of dry, clean air or inert gas and is engineered for industrial control, instrumentation and electronic equipment installed in applicable hazardous environments. Its corrosion-resistant construction and purpose-designed purge components provide a dependable solution for industrial facilities where hazardous gases or vapours may be present.
Purge and pressurisation is an established method of protecting electrical and electronic equipment in hazardous environments. Before normal operation, clean air or inert gas is used to purge potentially hazardous gases from the enclosure. Positive internal pressure is then maintained to inhibit the surrounding atmosphere from entering the protected enclosure.
The PCFF1YZ uses a continuous flow method in which protective gas continues to pass through the enclosure during operation. Its flush-mounted format makes it particularly useful where a streamlined installation is preferred, while Type Y and Type Z configurations support appropriately engineered hazardous-location installations in accordance with applicable system certification and installation requirements.
