Kawasaki Releases “Green” Sigma Ace 1.43 Series

Tokyo, February 27, 2008 — Kawasaki Thermal Engineering Co., Ltd. today announced the release of its Sigma Ace 1.43 series (JIS Standard COP 1.43). These are certified “Green Models,” meeting the revised, stricter environmental performance criteria for absorption chiller-heaters jointly established by Tokyo Gas Co., Ltd., Osaka Gas Co., Ltd., and Toho Gas Co., Ltd in 2005. The Sigma Ace 1.43 series was awarded Green Model status due to its superior energy saving performance and operational efficiency.

An absorption chiller-heater is a cooling/heating unit that uses gas or oil as fuel and water as a refrigerant. Kawasaki was the first in the world to commercialize this breakthrough technology in 1968. Since then, Kawasaki has been developing various related technologies as the leading manufacturer of absorption chiller-heaters which are widely used in hotels, offices, commercial buildings, schools, hospitals, district heating/cooling plants, and factories, both in Japan and around the world.

The Sigma Ace 1.43 series was designed as an upgrade to the preceding Sigma 1.4 series and includes a lineup of 15 models ranging in cooling capacity from 281 kW to 2,462 kW (80RT to 700RT).
