A low-temperature air-cooled water chiller is a machine that circulates coolant to lower equipment temperatures.
Refrigeration System
Dual independent refrigeration circuits support continuous operation under variable load conditions.
Compressor staged control adjusts cooling output according to system demand.
Electronic expansion valve regulates refrigerant flow based on real-time temperature feedback.
Air-cooled condenser system achieves heat rejection through forced airflow without external water systems.
Engineering Selection Parameters
Cooling capacity: multiple standard models available for different industrial load requirements.
Temperature range: selectable low-temperature operating range depending on process requirement.
Power supply: 220V / 380V / 415V / 440V / 480V industrial standards supported.
Refrigerant: R404A / R448A / R449A selectable based on temperature target and compliance needs.
System configuration: air-cooled or water-cooled structure with optional VFD control integration.
Principle
Refrigerant absorbs heat in the evaporator, is condensed, and throttled back to low-temperature vapor, forming a continuous cooling cycle.
