High-Efficiency Double-Effect Steam Absorption Chiller 150EXA

Download Catalog

The successful achievement of a steam consumption rate of 3.5 kg/h・RT. Constitutes the highest level of energy efficiency in the industry,*1 and allows to excel in reducing operating costs in applications such as production processes and clean rooms where they operate for long period of time. *1 In the case of a double-effect unit Operating costs saved by 9 million (JPY) per annum (compared with conventional model V series / 500RT); energy efficiency improved by 20% and operating costs saved by 12 million (JPY) per annum by replacing the chiller that have been used for 15 years. This double-effect steam absorption chiller uses a 2-stage evaporation and absorption cycle and plate heat exchanger. As a result, it reduces heat loss and achieves high efficiency easily while assuring high reliability and long life with a low concentration cycle.
