It is directly coupled to the electrical motor, with no external connections, reducing the number of internal and external components. The lubricant oil is continuously delivered by pressure difference to moving mechanical parts and power regulation piston. This system removes the need for an external oil pump, valves, and associated control mechanisms. The new Ciclonic oil separator is inside the compressor’s shell. No external oil connecting pipes are needed, which results in a compact design and high compressor reliability. In order to assure compliance with the specifications, Samurai chillers undergo a number of tests in the various production stages: The compressor is mounted on vibrations damper pads and is hermetically insulated. As optional, the compressor housing can be insulated with a double HITACHI patented liner, able to further reduce noise emissions. > Electrical and operation tests, > Pressure and leak check test. The new Cyclone oil separator is located inside the casing of the compressor. At the end of the production cycle a mechanical seal test is performed on the whole circuit, 16 critical chilling points and all welding points are checked. Before delivery, HITACHI performs a Run Test, connecting the Chiller both electrically and on the water side, testing all system variables, to assure correct Samurai operation. 246 Industrial and Service Sector Samurai Chillers and Heat Pumps Power (kW) NEW 100 200 500 1,000 2,500 5,000 Air cooled chiller Cooler Only R134A Modular RCME40~480AH5 106 kW ~ 1280 kW Air cooled chiller Cold Only RCU2E 40~400AG2 112 kW ~ 1030 kW Air Cooled Chiller Heat pump RHU2E 40~240AG2 Water Cooled Chiller Cooler Only and Heat Pump RCUE 40~240WG2 134 kW ~ 696 kW Condenser-less Chiller Cold Only RCUE 40~120CLG2 134 kW ~ 696 kW 106 kW ~ 585 kW 10,000 Industrial and Service Sector Samurai Cooling Only I Air Cooled NEW RCU2E-40~400 AG2 R efrigerant Gas R134a C ontinuous adjustment from 25 to 100% of compressor capacity Control on water output H igh Performance : EER > 3,52 and ESEER > 5.34 (depending on model) U p to 8 independent circuits Low noise level ICHIBAN Screw compressor E xclusive modular concept: Possibility to request delivery of assembled and connected (electrically and hydraulically) modules from the factory.
