The HITACHI R410A series water-cooled water chillers are designed for all the conveniences of chilled water air-conditioning systems, especially for hotels, stores, hospitals, modern building and process cooling applications of modern manufacturing industries. HITACHI water-cooled water chillers are equipped with newly-developed HITACHI A type semi-hermetic screw compressors, which feature higher precision and simplicity of construction by eliminating such items as pistons, connecting rods, valve plates, oil pumps and mechanical linkages for capacity controls in the reciprocating compressors. These features result in lower noise and lower vibration, reliable long period operation, and installation feasibility on any floor of the building. The units are composed of a compressor(s), a condenser(s), a direct-expansion water cooler, an electronic expansion valve(s), and auxiliary and control equipment. The units can be operated with the utmost simplicity.

FEATURES
The Combination of HITACHI Screw Compressor and Microcomputer Inclines HITACHI Water-Cooled Water Chillers to be perfect.
Discharge Gas Outlet Oil Separator Motor for Compressor Slide Valve

FEATURES
Lower Noise、 Lower Vibration and Reliable Long Period Operation… The Hitachi Screw Water Chiller Can Meet Your Requirements！ ！
Hitachi’s Semi-Hermetic Screw Compressor
The newly-developed HITACHI semi-hermetic screw compressors feature long life and quiet operation due to simplicity of construction when compared with the conventional reciprocating compressors.
Easy for Maintenance
Equipped with accessibility components such as Pressure Relief
Valve and Oil Sight Glass, easy maintenance is obtained.
A Symmetrical Rotor Profile and Other Features.
This profile of the compressor rotor, five-six (male and female) type, assures excellent efficiency even in high compression ranges, in addition to these uniquely-profile rotors, the following features are incorporated. Use of special bearing, resulting in long life and high reliability Patented capacity control system, enabling simple control system. High precision and high-grade finishing rotors, enabling no oil-cooling system.
Factory-Charged
The refrigeration cycle is charged with refrigerant and sealed under a strict quality control, therefore installation and operation can be performed in a short period of time.
Factory-Wires
Only power wiring and water piping are required in the field.
Most Reliable Protective and Ancillary Components Automatic Capacity Control
An Automatic capacity control mechanism enables the unit to perform economical and energy-saving operation depending on various conditions. Additionally, one(1) independent refrigeration cycles are provided for model RCUA160WHYZ(-E), RCUA220WHYZ(-E), RCUA280WHYZ(-E), RCUA300WHYZ(-E). two(2) independent refrigeration cycles are provided for model RCUA380WHYZ(-E), RCUA440WHYZ(-E), RCUA500WHYZ(-E), RCUA560WHYZ(-E), RCUA600WHYZ(-E). Three(3) independent refrigeration cycles are provided for model RCUA660WHYZ(-E), RCU720WHYZ(-E), RCUA780WHYZ(-E), RCUA840WHYZ(-E). The units are protected against any assumed failure of operation, based on the following components: Electronic Timer for Compressors, Three-Phase Quick Response Overcurrent Relay, Internal Thermostats for Compressor Motors, Freeze Protection Thermistors. Pressure Relief Valve, Oil Sight Glass, Oil Heater, and Reverse-Phase Protection Relays for Compressors.
Timer Counter
This timer counter indicates the operation hour of the screw compressor; therefore, accurate maintenance time can be checked with this timer counter.
Standard Accessories
The following accessories are supplied with the unit:
1. Vibration-Proof Rubber Mats 2. Foundation Bolts The combination of these mats and bolts effectively minimizes noise and vibration, and is coupled with facilitated installation procedures.
The following accessories are chose and bought by customers
1. Communication adapter connecting the unit to BMS (Building Management System) is an optional accessory. ( LONWORKS or RS485 for choosing) 2.

Note：
1、 The above uses (SPL-A) A scale sound pressure level data （dB） 。 2、 The measuring point is 1.0 meter from the center of the machine surface and 1.5 meter from the floor level。 3、 The units are operating under a standard working conditions。 4、 The sound data is measured on the flat, so the influence of the resonance should be considered while the unit is located in a rounding wall.
