• CAS accumulation tanks are engineered for integration into central heating systems with solid fuel firing boilers (Bio-Tec, BioSolid, EKO-CK P (EKO-CK), EKO-CKB P (EKO-CKB), EKO-CKS, CentroPlus, CentroPlus-B…) in order to store the heat en- ergy and enable economical and efficient functioning of the boiler. CAS are produced in seven different sizes (volumes 325, 475, 740, 940, 1450, 2160, 2960, 3820 and 5055 litres) and in four types: as an accumulation tank (CAS), as an accumulation tank for sanitary hot water processing with a built in stainless steel water heater (CAS-B), with an built in tube exchanger for connecting the solar collector (CAS-S), as well as with the built in stainless steel water heater and an tube exchanger (CAS- BS). These options enable contemporaneous use of different kinds of renewable en- ergies, making them ecologically acceptable and economical in use. • With a CAS accumulation tank connected to the system, the boiler firing can be per- formed in a suitable period of the day. If outdoor temperatures are milder, the room heating and the sanitary water temperature levels can be maintained across several days. Accumulation tanks are produced in accordance with ISO 9001/2008.

PRODUCT CHARACTERISTICS:

ISOLATION

They are well insulated with thermal insulation from the outside, bottom and top.

ISO

They are made of certified steel sheet ac- cording to ISO 9001 and ISO 14001 standards.

INTERCONNECTION

Containers can be interconnected to maximize total accumulation in the system.

EFFICIENT

Increase the efficiency and economy of solid fuel boilers.

• Designed to be connected to central heating systems in order to store heat energy. • Increases solid fuel firing boiler efficiency. • Made out of tested steel sheet in accordance with ISO 9001/2008. • Have good thermal insulation within a leatherette jacket. • Accumulation tanks can also be connected to each other as modules, in order to increase the total accumulationа.
