Steam Absorption Chiller is the ideal choice for a wide range of applications. YPC Steam Chillers come equipped with the same sophisticated microprocessor controls found throughout Johnson Controls’ line of large tonnage chillers, making the YPC Steam Chiller the smart- est and most efficient absorber on the market today. -
