Water-Cooled Condensers
All water-cooled condensers are cleanable shell and tube type with water in the tubes and refrigerant
in the shell. Each condenser is capable of holding the circuit pumpdown capacity. Independent
condensers serve the dual refrigerant circuits.
Each condenser is constructed with a carbon steel shell and seamless integrally finned high efficiency
copper tubes roller expanded into steel tubesheets. Water heads have vent and drain connections
and are removable. Also included is a liquid shutoff valve, purge valve, 450 psi (3104 kPa) relief valve
per ANSI/ASHRAE Pressure Vessel Code, Section VIII.
Water side working pressure is 225 psi (1550 kPa), refrigerant side is 450 psi (3104 kPa).
