Pressure-controlled Valve on cooling water circuit

• The purpose of this valve is to control cooling water flow to the condenser, so as to maintain the

high pressure at 16.5 bar (232-

240 Psi), which corresponds to water temperature of 40°C (exit

temperature).

• If mains water temperature exceeds 32

°C, the above values of high pressure and water

temperature at exit will be higher.

ADJUSTMENT: High pressure (and water temperature) can be decreased by opening valve (turn

screw clockwise).

Fan pressostat (air–cooled models)

High pressure is controlled by starting and stopping fan, which provides airflow through

condenser. Differential is fixed. (1Kg/cm2 or 14 Psi.) Cut-off pressure should be 16 Kg/cm2 (228

Psi.) Low pressure values in circuit may cause gearbox malfunction due to excessive ice

production. Pressure values higher than 14 Kg/cm2 will diminish ice production and may shorten

compressor life. Pressure can be regulated by rotating screw on Pressure Control Valve

(clockwise to increase pressure). One full turn is equivalent to about 1.5 Kg/cm2.
