Energy Saving

Water Cooled Chiller Image
  • TechnologyBuilt-in Cyclone Oil Separator
    • Low oil carrying-out is realized and reduction of heat
      transfer efficiency is minimized.
  • TechnologyNo outside pump is required due to the
        reliable differential-pressure oil-feeding
        system.
    • This oil-feeding system, which does not use
      any electrical mechanism, prevents the compressor
      from being damaged and maintains long-term stable
      operation.
  • TechnologyHigh Technology by Internal Manufacture
    • Because all manufacturing processes, from rotor
      manufacturing to unit assembly, are done internally,
      exceptional reliability is achieved.
    • TechnologyLow Vibration, Low Noise
      • Without the conventional demister chamber
        system, no noise is produced during oil separation
        of discharge gas. A vibration-proof base is not
        required for the chiller body thanks to the firmly-
        secured, low-vibration screw compressor.

Precise Capacity Control

Continuous Capacity Control

The temperature of the chilled water outlet can be kept at the set temperature ±1°C by continuous capacity control, so it is suitable for industrial use.

High Reliability

Simple Structure and Small Number of Parts

High Reliability Image

Whereas the number of main parts for the casing, compression mechanism and capacity control mechanism of a reciprocating compressor is 268, that of a screw compressor is only 27, just one tenth of the number. A structure with so few parts offers high reliability and easy maintenance.

Easy Maintenance

Modular System

Hitachi chiller units feature a modularization cycle structure, so each module can be packed and transported individually, for more convenient local installation and displacement. Furthermore, the refrigerant system of each module can be operated independently, which makes maintenance easier.

Compact and Light Weight

The Volume, installation space and weight are all reduced, making installation easy.

Safety Devices Equipped as Standard

The Hitachi chiller is equipped with several safety devices as standard. Those safety devices protect the unit from abnormal operation for higher reliability and longer lifespan of the chiller.

List of Safety Devices

  • Three-Phase Over-current Relay
  • High-Pressure Switch
  • Low-Pressure Switch
  • Oil Heater
  • Internal Thermostat for Comoressor Motor
  • Fusible Plug
  • Freeze Protection Thermostat
  • Reverse Phase Protection Relay
  • Discharge Gas Thermostat
  • Operation Hour-Meter and Safety Valve

Water Chillers From Hitachi


Hitachi Water Chillers removes the excess amount of heat from the liquid by using an absorption refrigeration cycle or vapor compressor. It comes with the H series that uses a heat exchanger for the liquid to be circulated to the cool air or any other equipment required. The water that gets chilled gets distributed to the coils or the heat exchangers in the air handling units.


The Hitachi Water Cooling Tower is made after quality engineering work and it has been giving the most critical on job performance since the past many years. The water chillers are available in a wide variety of commercial and industrial applications. As far as the design is concerned, it is very flexible and durable and it can last for a very long time. The water chillers from Hitachi are adapted to the needs of the consumer as well as in the industry. The overall construction is very simple and is portable for people to carry it from one place to another. The Water Cooling Tower is available in various capacities of vertical, horizontal and portable units.
