MIC has been manufacturing PREVAC for over 30 years. Originally designed for R-11 low-pressure chillers, and continued on R-123 chillers, it was an industry leading add-on for Trane, York, and Carrier units.
Now, with the new R-1233zd(E) chillers, PREVAC continues to add value to the building owner through cost savings, safety and code compliance, and to service contractors as a service tool that keeps their service people safe, reduces wasted service time, and keeps their customers happy.
The PREVAC System enhances the operation of low-pressure chillers using refrigerants R-1233zd(E), R-123, R-514a and R11. PREVAC prevents air & moisture infiltration in stand-by idle chillers, eliminates surging on start-ups, and prevents acid damage and refrigerant release. It also eliminates electrical code violations during servicing, by eliminating the need for temporary high voltage and temporary water hose connections. The PREVAC system provides 1/100 of 0.0 PSI control for minor repairs and features a high pressure alarm before the bursting disc is activated. This system complies with Ashrae 147, and enables safe and efficient chiller servicing.
The stationary PREVAC system provides:

Low-pressure chillers are expensive and integral pieces of equipment in a building's operation. Why not get the most out of them? And have them run better? PREVAC is a cost saving insurance policy for you as a building owner.
