What important containment features does the 19XL include?

The 19XL includes as standard refrigerant isolation valves in the compressor discharge line, cooler liquid line, and motor cooling line. Once these valves are closed you can easily pumpdown the chiller and store the refrigerant charge in the condenser to service the compressor. This eliminates the need for an external refrigerant storage tank and interconnections with the chiller. We also include as standard reseating pressure relief valves that reduce the risk of loosing the entire refrigerant charge if an overpressurization occurs. These type of relief valves are often installed at the job site in series with low pressure rupture disks that are provided as standard on low pressure HCFC-123 chillers.
