ORLANDO, Fla. - Receivers and reservoirs were among the newer refrigeration products on display at the 2005 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), where product innovations and the latest refrigerants competed for the spotlight.

Larger-capacity oil reservoirs contain two or three sight glass ports with float ball indications for oil level monitoring. Rotalock valves allow for adjustment when piping into the system. Models are 6 inches in diameter and range in length from 18 to 36 inches.
