Product details
Danfoss EKE 1C Superheat Controller | EEV Driver
Product Description:
The Danfoss EKE 1C is a specialized controller engineered to manage Electronic Expansion Valves (EEV) with extreme precision. In the demanding high-ambient climate of the UAE, maintaining the correct superheat is critical for both energy efficiency and preventing liquid slugging in compressors. The EKE 1C acts as a dedicated driver, utilizing advanced algorithms to ensure the evaporator is always fully utilized regardless of load variations. This DIN-rail mounted unit is a favorite for chiller manufacturers and cold storage operators in Dubai who require reliable, stable control and seamless integration with building management systems via MODBUS communication.
Key Features & Benefits:
- Optimized Superheat Control: Maximizes cooling capacity while providing superior protection for the compressor.
- Universal EEV Compatibility: Designed to drive a wide range of Danfoss bipolar and unipolar electronic expansion valves.
- Energy Savings: Precise valve positioning reduces the lift for the compressor, lowering electricity bills in the UAE.
- BMS Integration: Built-in MODBUS RTU communication for easy remote monitoring and system adjustment.
- Fail-Safe Features: Includes inputs for battery backup or internal safety functions to close the valve during power failures.
