CUSTOM VERTICAL CHILLED WATER TANKS
30 to 400 Gallon Sizes
(built to customers’ design)
- These tanks increase the capacity of a chilled water system and stabilize the return water temperature. This results in fewer cycles of the compressor and better temperature control overall.
- Properly-sized chillers keep chiller compressors from short cycling. Without the proper amount of system water, however, the temperature will rise and cause the compressor to shut off. If the compressor is off for too long, it cannot meet the demand for chilled water, which negatively affects your water system’s operations.
- A chilled water buffer tank is ideal for chillers with insufficient water volumes. It adds volume to help your water system buffer, preventing erratic system operations.
CUSTOM VERTICAL CHILLED WATER TANKS
400 to 2000 Gallon Sizes
(built to customers’ design)
- HANSON TANK manufactures two styles of 125# ASME chilled water tanks. Both vertical, they have either a vertical internal baffle with connections on the sides of the tank, or a dip tube on one of two connections on the top head. Please refer to the attached drawings for details. Chilled water tank standard connections are from 2″ to 3″ FNPT and 4″ to 8″ 150# Flanges. Grooved pipe stubs are available for all sizes instead. Tanks 42″ diameter and above have a 12″ x 16″ elliptical manway installed in the shell.
- R-16 foam insulation is also offered at reasonable price.
- The Chilled Water Buffer Tanks are built to order in 4 weeks.

Standard Chilled Water Tanks
- Factory insulation is also offered at reasonable cost.
- Hanson Tank Buffer Tank Sizes: Add 4″ for supports. (Please enquire for other sizes and connections)
- The ¾” top connection is for an air vent valve, for example a Honeywell Braukmann #EA79A1004.
- All sizes of Chilled Water Buffer Tanks are built to order in 4 weeks.
Custom Horizontal Chilled Water Buffer Tanks
- The size of tank is determined by deducting the capacity of the basic system from the desired capacity.
- For example, a 80 ton system with 200 gallons in it would need a 600 gallon buffer tank for optimum (ten gallons per ton) efficiency.
- Most chiller manufacturers recommend five gallons per nominal ton for a typical air conditioning system. In the above example, this would result in a 200 gallon buffer tank.
Hot Water Buffer Tanks
- A hot water buffer or volume tank improves system efficiency by adding extra thermal mass to the boiler water loop that circulates through a heat exchanger bundle.
- They are necessary with today’s smaller, high efficiency low mass boilers and also function as an air eliminator.
- As temperature stratification is not a major concern, they are usually built without internal baffles.
