Ray Products RPC-DPC Dual Purge Control System 115V 50/60Hz Purge Gas

Ray Products RPC-DPC Dual Purge Control System 115V 50/60Hz Purge Gas

The Ray Products RPC-DPC is a benchtop dual purge control system designed to manage purge gas flow and pressure in industrial enclosures and environmental test chambers. It provides two independently controlled purge flow paths — Low Flow Purge and High Flow Purge — along with a door-open status indicator and analog pressure monitoring, allowing operators to maintain safe positive-pressure purge conditions in enclosed spaces. Manufactured by Ray Products of El Monte, California.

Applications

Dual purge control systems like the RPC-DPC are used to maintain positive-pressure purge gas flow inside industrial enclosures, environmental test chambers, and hazardous-area electrical cabinets. Purging an enclosure with clean, dry air or inert gas displaces moisture, contaminants, or flammable atmospheres before and during operation — a requirement in many industrial and testing environments. The two independent flow channels allow operators to select a high-flow purge for initial chamber fill-down and then switch to a low-flow maintenance purge once the enclosure is cleared, conserving gas and maintaining safe conditions. The door-open interlock indicator is a common safety feature that alerts the operator when the enclosure has been breached, since an open door allows the purge atmosphere to escape. Units of this type have historically been used with environmental test chambers (temperature/humidity chambers, walk-in test rooms), purged and pressurized electrical enclosures in industrial plants, and specialty process equipment requiring a controlled internal atmosphere. The built-in pressure gauge in inches W.C. provides real-time confirmation that positive pressure is being maintained.
