Chiller with variable-speed compressor operates between 10 and 100 percent of its rated capacity. The design applies variable-speed green compressor technology from the HVAC industry to produce energy savings over hot-gas-bypass regulation. The chiller control allows for cloud-based remote management. Operational datasets include suction and discharge temperatures and pressures, water temperatures and pressures, and tank level. The datasets are logged, and alarms can be transmitted in real time to allow complete viewing and operational control via PLC, PC, tablet or phone. In addition, the chiller offers other standard communication protocols, including Modbus and Ethernet. The controls can regulate temperature to within 0.5°F. Electronic expansion valve technology provides metering to deliver precise refrigerant flow.
