Chilled Water Systems

 Chilled water systems require a certain amount of storage capacity in the system to reduce the workload of the chiller unit.  The technical team at GMS can help you size and select the buffer vessel you require, so please contact our sales and technical office for further information.

Heating Systems

GMS also manufacture buffer vessels for use as direct cylinders to store water from separate heat sources such as heat pumps, plate heat exchangers (also available from GMS) and many others. These are specially designed with sparges and baffles to ensure correct operation.


Should you require a quick turn around please see the GMS BBU range of buffer vessels available on express delivery.
