HFW-65HA1 Holtop Customizable Design Standard Air Conditioner for Different-Sized AHU Systems

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, while delivering strong cooling and heating output for stable operation across diverse climatic conditions.

Holtop modular air-cooled chillers are widely deployed across hotels, hospitals, shopping malls, office buildings, cinemas, the metal industry, oil and chemical industries, manufacturing, electronics, and power stations.

Each unit is engineered with more than ten safety protection functions, delivering all-round protection for both the chiller unit and the overall system. A multi-variable monitoring system enables centralized control, ensuring stable and efficient operation.

The chiller unit is suitable for operation across a wide outdoor temperature range, from -20°C to 48°C.

A single unit is designed with multiple compressors to support reliable, staged capacity control.

The chiller adopts a modular combination design and does not require a designated master or sub-master unit, simplifying system expansion and redundancy planning.

A standard RS485 building communication interface provides open access to the standard ModBus communication protocol for straightforward BMS integration.
