Chapter 32 - Closed Recirculating Cooling Systems | SUEZ

Heat, absorbed by the water in the closed system, is normally transferred by a water-to-water exchanger to the recirculating water of an open recirculating system, from which the heat is lost to atmosphere (Figure 32-1). Closed recirculating cooling water systems are well suited to the cooling of gas engines and compressors.
