Our buffer tanks are designed to increase a chiller system’s capacity so water temperatures stabilize within the chiller manufacturers recommendations. When the cooling systems piping capacity is under-sized, compressors will short cycle and temperature control is harder to maintain within the building.
Chiller manufacturers recommend between 3 to 10 gallons per ton of nominal cooling capacity, in the piping system. Depending on the level of accuracy of temperature control, higher volumes may be required.
Built to optimize modern-day chiller systems
Niles Steel Tank’s Buffer Tanks are designed for use with Commercial chiller water systems and hydronic heating systems which may have insufficient water volume to maintain optimum operating temperature control. Count on us for standard and custom configurations.

Sizing & Selection :
- Required Chiller Volume: ________ Gallons
Manufacturer of chiller unit’s recommended ‘gallons per ton’ of cooling. Typical 3 – 6 gallons per ton. Critical accuracy: 6 – 10 gallons per ton.
- Actual Gallon Volume in the entire chiller system: _______ Gallons (including piping)
(1) Chiller requirements gallons: _______ (-) minus (2) Actual gallons in system = _______ gallon size of buffer tank.
Niles Steel Tank manufactures a standard line of vertical and horizontal buffer tanks. Tanks are equipped with an internal baffle and standard flanged connections on 210 gallon and above. Baffles can be added to horizontal tanks as well. Since Niles Steel Tank is a custom tank fabricator, we would be happy to add or change our current design to suit your specific requirements. Grooved pipe end fitting are available in place of flanged connections. Our 2-part, closed cell foam spray on insulation can be added to any size tank and is durable enough for outdoor applications.
