  • Precision machining equipment centres

Saves Operating Costs
Placing the unit close to a cabinet/heat load avoids mixing of cold and hot air and can improve the whole system efficiency by 30%~45%. Adopting chilled water as the cold source for the central air conditioning equipment can improve the energy efficiency of the host. The supply airflow path of the fan is short; this reduces the operational energy consumption of the fan.

High Flexibility
The large heat load typical of a computer-room can be reduced incrementally, step by step. The unit is easy to expand, can be used on sites with or without raised floors and is applicable to the new or re-established projects. CHILLROW units are mutually independent and easy to maintain.

HYDROCOOL Water Cooled Chiller

The HYDROCOOL/HYDROCOOL-HE series of water-cooled water chilling units have a wide cooling capacity range and high reliability; they are applicable to large-scale data centres and various industrial process sites.

The HYDROCOOL-HE series unit is equipped with a flooded evaporator, which provides ultra-high energy efficiency and greatly reduces the energy consumption of air conditioners in data centres.  This series of units use an efficient and reliable screw compressor and an efficient flooded heat exchanger; they are small in size and can save space in a computer room.

227.2~3604.8kW

  • Commercial facilities
  • Industrial facilities

We employ optimal design to achieve optimal part-load operating characteristics and reduce annual operating costs. As the operating efficiency of different loads for each compressor varies the control centre automatically selects the optimal unloading scheme based on the load conditions; this achieves the highest operating efficiency for the whole unit giving optimal IPLVs.

Highly Efficient Heat Exchanger
Double-sided heat-exchanging tubes, are used for both the evaporators and condensers. Also, the flooded units are equipped with secondary oil separators; so the amount of oil which enters the heat exchanger will be no more than 0.05%; this greatly improves the heat exchange efficiency of such a heat exchanger. In the interest of efficient operation the size and weight of units and the charging quantity of refrigerants and lubricating oil can be easily controlled.

Configure Independent Cooling System for each Compressor
Each compressor configures an independent cooling system so as to increase the operational reliability of units.

In-factory Commissioning
All units, before leaving the factory, have passed our operation tests under actual operating conditions so as to ensure performance and reliability.
