TECH TIP #27

A quick guide to -
Refrigerant Cylinder Storage in Service Vehicles

Æ Store and transport refrigerant cylinders in an upright position out of direct sunlight

Æ Place sealing cap on outlet valve to prevent thread damage, seal out contaminants and prevent refrigerant leakage

Æ
Never allow cylinder temperature to exceed 130º F (54.4º C). Temperatures above 130º F could result in excessive cylinder pressure and damage to the container’s physical integrity resulting in a serious accident.

Æ
Keep refrigerant cylinders in original packaged carton thus keeping them from dents, punctures and scratches.

Æ
Visually inspect cylinders to ensure they are in safe condition.

Æ
Cylinders should be properly secured at all times to prevent tipping, falling or rolling around. They may be attached to a truck wall, cylinder truck, cylinder rack, or post.

Æ
R-410A cylinders have already been redesigned for higher pressure during normal transportation, use and handling.
