CEMLINE® Chilled Water Buffer Tanks (CWB) are designed to be used with chillers which do not have water volumes of sufficient size in relation to the chiller. The insufficiently sized systems do not have enough buffer capacity for the chilled water causing poor temperature control, erratic system operation and excessive compressor cycling.

The CWB solves this problem by adding volume to buffer the system. The CWB reduces the rate of change of the return water.

Chillers are designed to be useful in systems with a minimum water volume. The minimum water volume is based upon the chiller manufacturer's requirements, typically 3 to 6 gallons per ton when the temperature accuracy is critical. When chiller systems are properly sized, the chiller compressor will not short cycle. Without the proper amount of system water, the source temperature will be reached quickly and the compressor will shut off. Many chiller compressors can only start 3 times per hour. If the compressor is off and there is a demand for chilled water, the demand can not be met because the compressor cannot turn back on. This causes very unsatisfied people within the building who cannot have the required cooling. Insufficiently sized system problems can cause excessive compressor cycling, poor temperature control and erratic system operations.
