Centrometal Accumulation tanks are available in sizes from 475 litres to 5000 litres and can also be connected in modules
CAS accumulation tanks store heat energy for controlled release according to heating demand.
They increase the overall efficiency and economy of biomass boilers.
They have good thermal insulation through 100mm and 130mm foam covered in a rigid, durable plastic jacket
CAS tanks assist the boiler to operate in the most efficient manner to extend boiler life and lower maintenance costs
In milder ambient temperatures, CAS tanks permit reduced boiler firings and the retention of heat over several days
CAS tanks can be installed with integral hot water tanks and connections with tube heat exchangers for other renewable heat sources.
Options include heating coils for solar or other source of heating input, CAS – PBS tanks in 855 and 1000 litres with rapid heating coils, solar and other heat source input, and a system to layer or stratify the stored heat. These are insulated to 130mm thickness.
Suggested sizing criteria for CAS accumulation tanks :
For wood gasification and log boilers, a minimum of 50 litres capacity per 1Kw heat output
For pellet fired boilers, a minumum of 30 litres capacity per 1 Kw heat output.
Installation requirements vary according to space available, building heat loads and other renewable heat sources available.
