Ranco P30-3701 Lube Oil Pressure Safety Control 90 Second Delay

The Ranco P30-3701 is a lube oil pressure safety control designed to protect refrigeration and HVAC compressors from inadequate oil pressure conditions. This control monitors the oil pressure differential and automatically shuts down the compressor if oil pressure falls below safe operating levels, preventing costly damage to the equipment.

Key Features:

• 90-second time delay prevents nuisance shutdowns during normal startup
• 36-inch capillary tube for flexible installation and remote sensing
• Automatic reset functionality for convenient operation
• Differential pressure control design monitors net oil pressure
• Rugged construction suitable for commercial refrigeration and HVAC applications
• SPDT switching for versatile control configurations

This oil safety control is essential for protecting compressor longevity in walk-in coolers, freezers, ice machines, air conditioning systems, and other commercial refrigeration equipment. The control continuously monitors the pressure difference between crankcase pressure and oil pump outlet pressure to ensure adequate lubrication.
