REDUCE YOUR

OPERATING COSTS WITH THE

llLITTLE GIANT" PIIIIGEII

The "Little Giant" Purger is an essential item and a profitable investment that quickly pays for itself because:

K

It reduces power costs It saves expensive refrigerant It reduces wear and tear on equipment

When non-condensable gases are present in a refrigerant system, it will operate at higher pressures than it would if these gases were not present. Unnecessarily high pressures result in the compressor being subiect to:

Higher bearing loads

Higher discharging temperatures Increased wear on moving parts Greater power consumption

It is particularly important that the refrigeration system be purged after a shut-down period of any considerable time. The usual practice is to pump the refrigerant back into the receiver and lock it in by means of valves. Repairs or alterations are made on the system during this time, and it is practically impossible to evacuate the system completely, with the result that the remaining air will cause excessive head pressures.

HERE ARE THE ADVANTAGES 0F PURGING WITH THE "LITTLE GIANT" PURGER:

THERE IS NO GUESSING -There is positive indication when purging is necessary. The sight glass gives visible evidence of non-condensable gases in the system.

NO REFRTGERANT LOSS -The air in the system' is completely separated from the refrigerant before the purge valve is opened.

SIMPLE TO OPERATE-All operating valves easilyaccessible. Not necesorry to check pressures or temperatures. No need to shutdown the system.

POWER SAVINGS-Power savings, due to a reduction in head pressure will pay for the "Little Giant" many times over.

MANUAL OPERATION-Fully manually operated, there is no possibility of a slow leak developing which would cause a loss of refrigerant before cause is discovered.
