Remote sump tank selection

Remote sump tanks help prevent frozen cold water basins however cold it gets.

We usually house them in a heated indoor space, to eliminate the need for
winter-proofing evaporative cooling equipment.

A remote sump tank must also provide sufficient storage volume to accommodate all the water flowing back during cooling system shutdown, including:

• Unit volume: the total volume of water contained within the unit during operation

• System piping volume: the volume of water contained in all the system piping above the operating water level of the remote sump tank

• System component volume: the volume of water contained within any heat exchanger, or other equipment located above the operating water level of the remote sump tank and which will drain into the tank upon cooling system shutdown.

Check out the cold water basin volumes for

• Open cooling towers: VXT, VTL, TXV, S3000D, PTE, FXT.
• Closed circuit cooling towers: VXI, VFL, FXVE, FXV-D, PFE, HXI.
  HFL cooling towers do not require remote sumps due to its unique design.
• Evaporative condensers: VXC, VCL, CXVE, CXV-D, PCE
