Product Overview
Touchscreen HMICooling / HeatingCOP & EERMultiple Refrigerants
Key Features
- Interactive Touchscreen HMI: Equipped with a programmable Human Machine Interface (HMI) touchscreen that provides total digital control over compressor operation, valve actuation, fan speeds, and mode selection.
- Reversible Heating/Cooling Modes: Features an electronic 4-way reversing valve allowing instant switching between standard refrigeration cooling and reverse-cycle heat pump heating.
- Multi-Refrigerant Versatility: Engineered to operate safely with four industry-standard refrigerants (R-134a, R-600a, R-32, R-410A) for comprehensive comparative research.
- Precision Circuit Architecture: Incorporates 1 inline sight glass, 4 automated solenoid valves, forced fans, high-capacity receiver, and suction accumulator.
- Anti-Corrosion Protection: All exposed copper tubing is specially painted and treated to prevent oxidation and environmental corrosion.
