DANFOSS 080G5300 EKE 1A Superheat Controller

Product Overview:

The DANFOSS 080G5300c EKE 1A Superheat Controller gives commercial refrigeration and air conditioning systems exact control over superheat. This electronic controller makes the evaporator work better, saves up to 20% on energy, and works with Danfoss stepper valves like the ETS Colibri and CCMT series.

The EKE 1A is designed to keep superheat levels low even when the load changes, which makes it very accurate. It works well in heat pumps, food retail refrigeration, and industrial cooling, among other things, because it keeps things running smoothly and lowers costs. Some of the most important features are adaptive superheat references, alarm handling, and defrost integration, which all help the device work well every day.

Technical Specifications (DANFOSS 080G5300)

080G5300 Superheat Controller Features:

1) Adaptive Superheat Control has different modes, such as fixed, load adaptive (LoadAp), MSS, or delta SH for making changes on the fly.

2) Valve Compatibility: It can drive Danfoss ETS, KVS Colibri, CCMT, and CTR valves with microstep precision of up to 400 pps.

3) Advanced Functions: It can handle defrost sequences, MOP/LOP limits, reversible systems for heat pumps, and external references.

4) User Interface Options: You can connect with a KoolProg PC program or an MMIGRS2 display (up to 3m cable) for setup and trending.

5) Safety and Dependability: galvanic isolation, battery backup for closing the valve when the power goes out, and alarms that cover everything.

Installation Guidelines

Mount in a protected panel on a DIN rail, preferably in a vertical position. Use M12 cables (up to 30m with adjusted drive current) to connect power (24V), sensors (S2 NTC at the evaporator outlet with paste, Pe transmitter post-evaporator), and valves. Use the setup wizard to choose the refrigerant, calibrate the sensors, and set the SH setpoints. Always keep the signal and power wiring separate to avoid interference.

Industry Applications:

Great for commercial refrigeration setups that need precise superheat control, such as display cases, cold rooms, and transport units. It uses digital inputs to switch between heating and cooling modes in air conditioners and heat pumps. Its limitation functions and service modes help industrial processes by keeping downtime to a minimum.
