PRELIMINARY
Check that the gascooler has not been damaged during transport and that no parts are missing.
Check if gascooler is under pressure at arrival with a charge of nitrogen U 3 Bar +/- 0.5 Bar.
If gascooler was damaged or if the delivery is incomplete, make remarks on the receipt reservations of transport and confirm them by
letter with acknowledgment of receipt within 48 hours to the carrier with a copy to PROFROID.
If the delivery does not correspond to your order, contact PROFROID.
Gascoolers SV (vertical air flow) must be positioned on their running positions, or inside a building, in order that water doesn’t go
inside electrical equipements.

DESCRIPTION – OPERATIONS
Because gascoolers are delivered as a semi-finished product, we are not necessarily aware as a manufacturer about the
end use. Proper use of gascooler is always the responsibility of the end user.
The use of gascooler is implicitly linked to the PS and TS design.
APPLICATIONS
Gascoolers in the SOPRANO50 CO2 & TENOR50 CO2 range are designed for internal installation in all refrigeration and air
conditioning applications.
Fluid : R744 (CO2)
PS = -1 / 120 bar
TS = -40 / 120°C
Transcritical running when P > 73 bar (T > 31°C) or subcritical for others cases.
BODY
Designed in pre-painted sheet metal (RAL7035).
Individual separation of fans in order to optimize the circulation of air.
Hoisting holes on SO50. Palet truck on TE50.
COIL
Gascoolers are fitted with one or many coils with profiled aluminium fins and copper tubes (CuFe2P).
Refrigeration joints to be welded (stainless steel 304L or copper CuFe2P).
VENTILATION
EC Fan centrifugal motors.
They are equipped with an electronic switch for continuous speed variation and independent control for each
motor fan. Common characteristics of these motors:
Important : the maximum imbalance between phases is 2% in voltage and 10% in current per motor.
