3.5 Cooling The Recovery Tank
The Vortex can be used to PRE-cool (or SUB-cool) the recovery tank if the
head pressure is too high to complete the recovery process. This can occur
when working with certain refrigerants with a high vapor pressure when the
ambient temperature is high.
If the recovery process stalls out because of high head pressure, stop the
Vortex, shut off the hose valves and reconfigure the setup as shown in Figure
3-4. This can also be done before starting the recovery process, but it may
have marginal long term effect.
NOTE: This will only work if there is at least 2 kg of liquid in the recovery
tank to develop the necessary pressure differential required.
