7.6 Evacuation and Dehydration

7.6.1

General

Moisture is detrimental to refrigeration systems. The presence of moisture in a refrigeration system can have many

undesirable effects. The most common are copper plating, acid sludge formation, “freezing-up” of metering devices

by free water, and formation of acids, resulting in metal corrosion.

7.6.2

Preparation

1. Evacuate and dehydrate only after completing a pressure leak test. See

Section 7.5

2. Essential tools to properly evacuate and dehydrate any system include a vacuum pump (8m3/hr = 5 cfm

volume displacement) and an electronic vacuum gauge. The pump is available from Carrier Transicold, P/N

07-00176-11. The micron gauge is P/N 07-00414-00.

3. If possible, keep the ambient temperature above 15.6°C (60°F) to speed evaporation of moisture. If the

ambient temperature is lower than 15.6°C (60°F), ice might form before moisture removal is complete. Heat

lamps or alternate sources of heat may be used to raise the system temperature.

4. Additional time may be saved during a complete system pump down by replacing the filter drier with a

section of copper tubing and the appropriate fittings. Installation of a new drier may be performed during the

charging procedure.
