In such circumstances, it is even more important to save the energy consumed by air conditioners in order to cut CO emission.

Chlorofluorocarbons (CFCs) in the stratosphere are exposed to ultraviolet rays which decompose them, and generate chlorine atoms.

Because HFC34a has no chlorine atoms, it does not destroy the ozone in the atmosphere.

2 The HighEfficiency WaterCooled Flooded Chillers The New WaterCooled Flooded chiller with improved efficiency and functionality by incorporating several advanced technology and features. This series with the world s best standard semihermetic screw compressors and newly designed shell and tube heat exchangers that have powerful cooling ability, low noise, low vibration, high efficiency and high reliability is the perfect answer to all your needs! Hitachi SemiHermetic Screw Chillers Show a Remarkable EnergySaving Effect & are Friendly to the Global Environment Global Warming Prevention Energy saving by higherefficiency screw chillers Global warming refers to the phenomenon of global rising in average atmospheric s due to increased volume of CO & methane as a result of burning fossil fuels such as petroleum and coal. The995 IPCC* Report predicted that if the emission of CO,etc. continued as it was, the atmospheric would rise by as much as C by the end of the st century and, as a result, the sea level would rise by approx. 50 cm from the present level. In such circumstances, it is even more important to save the energy consumed by air conditioners in order to cut CO emission. *IPCC: Intergovernmental Panel on Climate Change Ozone Layer Protection Use of HFC34a refrigerant has an ozone depletion potential of zero Chlorofluorocarbons (CFCs) in the stratosphere are exposed to ultraviolet rays which decompose them, and generate chlorine atoms. It is thought that the chlorine atoms combine with oxygen atoms in ozone to destroy the ozone. Because HFC34a has no chlorine atoms, it does not destroy the ozone in the atmosphere. Enhanced Lineup: from 43RT to 458RT Highperformance Semihermetic Screw s High efficiency shell & tubes flooded type evaporators High efficiency shell & tubes condensers Highly efficient external 3 stages oil separator, up to 99.96% oil separation Harmful ultraviolet rays Ozone layer destruction (ozone hole) Sun Ordinary ultraviolet rays Surface of earth Ozone layer Chlorofluorocarbons, etc. The ozone layer cuts harmful ultraviolet rays Chlorofluorocarbons destroy the ozone layer to generate ozone holes Ozone holes are expanded to increase harmful ultraviolet rays. Serious menace to the existence of terrestrial life Skin cancer, cataract and reduced harvests

Technical Features High COP In the new model series, the power consumption is largely reduced over the current model series due to newly designed highefficiency cooling system.

3 Technical Features High COP In the new model series, the power consumption is largely reduced over the current model series due to newly designed highefficiency cooling system. High efficiency oil separation Precise Capacity Control Technology The of the chilled water outlet can be kept at the set ± C by continuous capacity control, so it is suitable for industrial use.
