Reconditioned

The Danfoss EKD 316 (Part No. 084B8040) is a superheat controller designed for precise regulation of refrigerant flow in HVAC and refrigeration systems. It operates electronic expansion valves (EEVs) to maintain optimal superheat levels, enhancing system efficiency and reliability.

 Key Features

• Reconditioned for like-new performance at a more affordable cost

• Superheat Regulation: Utilizes PID control to maintain stable superheat, ensuring efficient evaporator performance.

• Minimum Stable Superheat (MSS): Automatically adjusts superheat setpoints to the lowest stable value, optimizing energy use.

• Maximum Operating Pressure (MOP): Limits evaporator pressure to protect compressors during high-load conditions.

• Valve Compatibility: Supports Danfoss ETS, CCM, and CCMT series valves, including models from CCMT 0 to CCMT 42 and ETS 6 to ETS 400.

• Communication: Equipped with RS-485 Modbus interface for integration with building management systems.

• Alarm Relay: Includes an SPDT relay for alarm signaling, enhancing system safety.
