The CWM Series is high-efficiency modular water to the water heater. These units range in heating capacity from 270MBTUH to over 2,000MBTUH generating from 323 to 2,584 gallons of hot water per hour. While these units are heating water up to 150°F, (condenser side), they are also cooling the source water, (evaporator side), which can be used for chiller water for air conditioning systems or process water for cooling of the equipment.
