TECHNICAL DATA AND PERFORMANCES
COOLING performances
The performances of the units, when used as brine - water, are referred to applications in which the source side fluid is a solution of
water and 30% ethylene glycol by volume.
Such a concentration guarantees a freezing temperature of about -15°C and allows the unit to work inside the declared operating
limits.
The graphs allow to get the corrective factors to be applied
to the nominal performances in order to obtain the real
performances in the selected operating conditions.
The reference nominal conditions are :
WATER-WATER units : W30W7
source : water in 30°C out 35°C
plant : water in 12°C out 7°C
BRINE-WATER units : B30W7
source : brine in 30°C out 35°C
plant : water in 12°C out 7°C
