ESA SERVICE provides assistance in choosing the
most suitable solution according to Customer’s requirements,
installation, start-up and maintenance of refrigerant gas filling and
recovery units.
REA – LOW PRESSURE HELIUM RECOVERY SYSTEM
The REA unitkeeps
always on vacuum the suction tube and on pressure the delivery tube,
so the helium is available in any moment, at the desired pressure.
Helium concentration is always kept under control by an
analyzer. If the measured value goes under an alarm level, pure helium
is inlet in order to restore the concentration to a pre-set value.
This unit is used in the refrigeration and air
conditioning industry to recover the refrigerant gas from the circuits
previously charged.
The recovery unit is provided with one suction line and
three delivery lines: through these ones, the refrigerant gas can be
recovered and sent to the storage bottles.
The start-up of cycle is automatic.
Pressure is controlled in both circuits by means of pressure switches
and displayed on two pressure gauges located on the front panel of the
unit.
