Retro Pumps
1 / 5
🚀 Commercial DC Inverter Air Source Heat Pump
Designed for HEATING + COOLING. Features DC Inverter compressor & R410A refrigerant. Maximum water output temperature reaches 60°C, with an ultra-low working ambient temperature capability of -35°C.
❄️Intelligent Defrosting Technology
Accurately judges defrosting timing based on heating operation parameters and load changes. Achieves precise defrosting to maintain normal heating without unnecessary attenuation. Manual forced defrosting is also supported.
Units of different capacities can be freely combined. Up to 16 units can be connected in parallel, achieving a maximum cooling capacity of 2080kW. This flexible installation fully meets diverse site requirements and reduces power grid impact through staged starting.
📱Smart Control & Protection
Equipped with Modbus protocol for BMS building control systems. Optional WiFi function allows remote smartphone control anywhere, anytime. The system includes multiple protections: high/low pressure switches, antifreeze devices, water flow switches, and overload protection.
Sensata Pressure Sensor: Excellent precision and EMC protection for stringent conditions.
Electronic Expansion Valve: High-precision flow control for system stability.
Shell & Coil Heat Exchanger: High efficiency with strong antifreeze ability and stable performance.
Our production line and laboratories are equipped to handle extreme conditions. The performance laboratory can test units down to -35°C, ensuring high reliability in cold climates.
