The Holtop modular air-cooled chilled water heat pump unit is purpose-built for HVAC air handling unit (AHU) applications, combining outstanding performance with high energy efficiency. Its modular design enables flexible combination to suit AHU systems of varying capacities. With robust cooling and heating capabilities, the unit operates reliably across diverse climatic conditions.
The Holtop modular air-cooled chiller is widely deployed across hotels, hospitals, shopping malls, office buildings, cinemas, the metal industry, oil and chemical industries, manufacturing facilities, electronics production, and power stations.
More than 10 safety protection functions are engineered into each unit, delivering all-round protection for both the chiller and the overall system. A multi-variable monitoring system enables centralized control, ensuring stable and efficient operation at all times.
The chiller unit is designed for reliable operation across a wide outdoor temperature range, from −20°C to 48°C, ensuring dependable performance in demanding climates.
Each single unit is equipped with multiple compressors, enhancing part-load efficiency, redundancy, and operational flexibility.
The chiller adopts a modular combination design that eliminates the need to designate a master or sub-master unit, simplifying installation, expansion, and system balancing.
A standard RS485 building communication interface is provided, with open access to the standard ModBus communication protocol for seamless integration into building management systems.
