Re: Rental Contingency Plan

Dear Mr. Cobarris

This letter is provided to assist Bay Pines VA with a HVAC rental contingency plan in the event the primary water cooled chillers in Plant #1 fail or both emergency air cooled chiller #6 & #7 fail.

Chiller Plant #1 Water Cooled Chillers

Chiller Plant #1 currently has 4 Trane centrifugal water cooled chillers. In the event of failure of all 4 centrifugal chillers a rental water cooled chiller(s) option could be implemented and tied into the chiller plant. Trane offers rental water cooled chillers ranging in tonnage from 225 – 1000 tons.

Depending on tonnage requirements at the time multiple water cooled chillers could be provided.

Rental water cooled chillers will need to be connected to the chiller plants supply and return chilled water piping as well as supply and return condenser water piping. The selection of the rental water cooled chiller will determine the power requirements. In the event Bay Pines VA does not have efficient house power to operate the rental chillers a rental diesel generator could be provided to power the rental units. All materials and labor to provide, install and operate the chillers can be provided.

Chiller Plant #1 Emergency Air Cooled Chiller #6 & #7

Chiller Plant #1 currently has two backup 200 ton air cooled chillers designated chiller #6 & #7 that provide backup to the operating rooms in the event the water cooled chillers in Plant #1 fail. In the event backup chiller #6 & #7 fail a rental air cooled chiller option could be implemented and tied into the chiller plant. Trane installed rental taps into the supply and return chilled water lines in chiller plant #1 in the event the backup air cooled chillers failed. Trane offers rental air cooled chillers up to 500 tons. The rental air cooled chiller would connect to the existing rental taps in chiller plant #1. The selection of the rental air cooled chiller will determine the power requirements. In the event Bay Pines VA does not have efficiency house power to operate the rental air cooled chiller a rental diesel generator could be provided to power the rental unit. All materials and labor to provide, install and operate the chiller can be provided.
