RWR462.10 Siemens Superheat Controller IP20 Dry Expansion Evaporator 50/60 Hz
Product Highlights
- Precise Control: Designed specifically for dry-expansion evaporators, it regulates superheat in real time, preventing compressor liquid slugging and energy efficiency degradation.
- Wide Application Range: Covers a cooling capacity range of 1.5 kW to 740 kW (based on R407C, 0°C/40°C operating conditions).
- Plug-and-Play: IP20 protection, DIN rail or screw mounting, compact size (57×142×130 mm), no additional brackets required for retrofit installations.
- Industrial-Grade Reliability: 50/60 Hz universal power supply, operating temperature -20...+55 °C, CE & RoHS certified, MTBF > 10 years.
- Energy-Efficient: Optimizes evaporator utilization, reducing energy consumption by 8%–12%.

Three-Step Installation Guide
1. Connect the pressure sensor to the evaporator outlet; attach the temperature sensor to the suction line 10 cm from the evaporator outlet.
2. Mount the controller on a 35mm DIN rail; connect the AC 24V power supply and valve control wires.
3. Power on to automatically detect the sensors; set the desired superheat value using the DIP switch (default: 6K).
