HOLTOP MODULAR AIR COOLED CHILLER(AIR SOURCE HEAT PUMP)

Air Cooled Chillers are our latest product based on over twenty years of research & development, technology accumulation and manufacturing experience which helped us to develop chillers with stable & reliable performance, greatly improved evaporator & condenser heat transfer efficiency. In this way it’s the best choice to save energy, protect environment and achieve comfortable air conditioning system.

Designing more than 10 safety protection functions, which can ensure chiller unit and the system operation in all-round protection. The unit can be controlled through a multi-variable monitoring system to ensure the unit with stable and efficient operation.

Chiller unit is suitable for operation in a wide outdoor temperature range, from -20C~48℃.

A single unit is designed with multiple compressors.

The chiller adopts modular combination design and does not need to set the master or sub-master unit.

Starting all units in steps, in order to lower the starting current, reduce the shock to power grid, and avoid affecting the security of other electrical equipment.

By sensing with the multi-variables system to have accurate judgement on the situation of frosting, the chiller itself can be able to choose the best time to enter or exit defrosting, to avoid insufficient defrosting or over defrosting. In a duplex system, the units can achieve alternate defrosting. When heating under extreme low-temperature conditions, setting manual defrosting for better performance.

Standard RS485 building communication interface comes with open access to standard ModBus communication protocol. The device can be easily connected to the building control system (BAS) for centralized control, easy to achieve intelligent control, avoid unnecessary energy waste, and save air-conditioning operating costs.
