Meet DOT 400 Specifications, ARI Certify

• Liquid and vapor valves ("Y" valve or separate valve configurations) are installed in all cylinders 3/4 in plug Pressure relief/safety valve is set to release at between 75 - 100% of the test pressure

DOT Classified for recovery, recycling, service and reclaim. Liquid and vapor valves (Y valve or separate valve configurations) are installed in all cylinders. Painted yellow/gray per ARI guidelines. Float switches have 3-pin Brad Harrison connectors. Caution - never overfill cylinders. Maximum refrigerant capacity is limited to 80% of the water capacity of the cylinder in lbs. DOT requires cylinders to be retested every 5 years. Some recovery equipment uses weight scales to cut-off refrigerant fill at 80% of capacity. Be sure cylinder tare weight is correct for this type of equipment. DOT Classification example: 4BA400: 400 psi working pressure, 800 psi test pressure (double the working pressure), 1600 psi minimum burst pressure (double the test pressure). Pressure relief/safety valve is set to release at between 75 to 100% of the test pressure. For example, in the 4BA400 tanks which have a 800 psi test pressure, the relief valve opens at between 600 and 800 psi.
