PREVAC AquaPower

This unit is a permanently installed refrigerant pressure controlled system for idle R-11 & R-123 chillers that circulate heated water through the evaporator for: 

1. Pressure sealing a chiller during idle periods to prevent chiller downtime, prevent refrigerant contamination and acid damage, and eliminate hard start-ups and improve reliability. 

2. Push-button pressurization to enable service personnel to conform to EPA, ASHRAE, NEC & Local Building Codes when leak testing, perform minor repairs at 0.00psig to prevent refrigerant losses in compliance with EPA Clean Air Act, Improve response time for leak repairs to minimize downtime, and repair leaks fast to eliminate non-condensables, higher head pressures and wasted energy. 

3. Chiller over-pressurization warning and pressure reducing capability to notify operating personnel before rupture disc bursts and initiate corrective actions before the rupture disc bursts.

• Pressure Sealing a chiller during idle periods to:
• Prevent chiller downtime
• Prevent refrigerant contamination and acid damage.
• Eliminate hard start-ups and improve reliability

• Push-Button Pressurization To:
• Enable service personnel to conform to EPA, ASHRAE, NEC and local building codes when leak testing
• Perform minor repairs at 0.00 psig to prevent refrigerant loses in compliance with EPA Clean Air Act
• Improve response time for leak repairs to minimize downtime
• Repair leaks fast to eliminate non-condensables, higher head pressures and wasted energy

• Chiller Over-Pressurization Warning and Pressure Reducing Capability To:
• Notify operating personnel before a rupture disc bursts
• Initiate corrective actions before the rupture bursts, not after!
