Refrigerant Recovery Cylinder

Last updated: March 11, 2026

A refrigerant recovery cylinder is a specialized pressurized container designed to safely capture and store used refrigerant recovered from HVAC systems during maintenance, repair, or decommissioning. Recovery cylinders feature higher pressure ratings than standard storage cylinders, typically rated for 400 to 500 pounds per square inch, to accommodate vapor pressure fluctuations. These cylinders must include a liquid shutoff valve and compliance verification with EPA regulations for proper refrigerant handling.

Technical Specifications

Recovery cylinders are manufactured with heavy-duty construction and feature low-loss fittings to minimize refrigerant escape during transfer operations. Cylinders include fill-level indicators and internal check valves preventing backflow contamination. Maximum fill levels are strictly regulated at 80 percent liquid capacity by weight to prevent overpressurization if temperatures exceed 100 degrees Fahrenheit during storage or transport.

Regulatory and Environmental Function

EPA Section 608 certification requires proper refrigerant recovery using appropriate cylinders to prevent atmospheric release. Recovery cylinders enable technicians to capture refrigerant from systems before disposal or equipment retirement. After recovery, cylinders are sent to certified reclaim facilities where refrigerant is purified and reused, reducing environmental impact and resource consumption in the HVAC industry.
