Mechanical Ingenuity Corp. 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-1233zde chillers, PREVAC continues to add value to the building owner through cost savings and safety and code compliance, and to service contractors as a service tool that keeps their service people safe and their customers happy.
The PREVAC System enhances the operation of low pressure chillers using refrigerants R-1233zd, R-123, 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:
PREVAC Portable is a state of the art pressurizing system which provides unparalleled performance and safety in raising the water temperature inside the evaporator of a low pressure centrifugal chiller for the purpose of leak testing and performing minor repairs at zero pressure in compliance with the EPA Clean Air Act.
Benefits of the mobile system:
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.
