The P70, P72, and P170 Controls for Dual Pressure Applications are designed primarily for use as combination high and low pressure controls on commercial refrigeration and air conditioning applications. These controls are available in several pressure ranges and are compatible with most common refrigerants. Ammonia compatible models are also available. These controls respond directly to system pressure changes on both high and low sides, and can provide single-device control of the compressor.

• Single input sensor model
• Start voltage - 10% of supply voltage
• Electronic fan speed controls are refrigerant pressure actuated, electronic motor-speed controllers
• Provide condenser pressure control by directly sensing condenser refrigerant pressure and automatically adjusting the condenser fan motor speed according to the sensed pressure
• Provides an alternative to fan cycling control in many small and medium size refrigeration and heating, ventilating and air conditioning (HVAC) applications
• Pressure transducer responds quickly to condenser pressure changes and condenser air delivery requirements
• Soft start capability provides a smooth fan startup, which reduces motor-starting noise and abrupt changes in motor speed
• Built-in voltage surge protection, radio frequency interference (RFI) suppression and ground terminal screw
