VaporSaver II Refrigerant Relief Valve /

Rupture Disk Assembly

Save tons of expensive CFC refrigerant during overpressure emergencies.

If your low-pressure chiller develops an overpressure emergency, you could lose the machine's entire refrigerant charge in an instant. And face the expensive problem of replacing all that increasingly scarce refrigerant.

Or, you could let VaporSaver II provide automatic, immediate pressure relief - and bring refrigerant loss to a dead stop once safe pressure is achieved.

VaporSaver II combines a full-metal, non-fragmenting rupture disc with a relief valve to provide the fastest response possible to sudden pressure spikes, while resealing the chiller once internal pressure is reduced to a safe level. Response is actually so tight that the valve opens and closes within 10% of its set pressure. So refrigerant stays inside your chiller, and out of the atmosphere.

VaporSaver II meets recommendations of ASHRAE Guideline 3-1990, Section 4.6 and ASHRAE 15-1994.
FeaturesBenefits
Minimizes refrigerant losses during overpressure emergencies, Tightly seals chiller after safe pressure is achieved. Conserves increasingly scarce and costly CFC refrigerant.
Keeps air and other contaminants out of the chiller following emergency pressure relief. Prevents hardware damage.
Single-unit, relief valve and rupture disc. Reduces installation cost.
Chiller remains in service until rupture disc can be replaced. Minimizes downtime.
Can be connected to remote alarm or monitoring system, Tell-tale assembly provides local indication that disc is broken. Provides immediate warning of pressure release.
Used with CFC-11, -113, -114, or HCFC-123* chillers. Protects your investment.

*Carrier does not recommend the use of HCFC-123.
