Characteristics of CAS buffer tanks

— They are intended for installation in central heating systems to accumulate thermal energy.

— They increase the efficiency and economy of biomass boilers.

— They are made of certified steel sheet in accordance with ISO 9001 and ISO 14001.

— They are well insulated with thermal insulation with a Skai jacket.

— The tanks can be connected to increase the total accumulation in the system.

— Standardno se izrađuju u sljedećim veličinama i izvedbama:

* CAS 301 (325 liters), CAS 501 (475 liters), CAS 801 (740 liters), CAS 1001 (940 liters),

CAS 1501 (1435 liters), CAS 2001 (1920 liters), CAS 3001 (1920 liters), CAS 3001 (2960

liters), CAS 4001 (3820 liters), CAS 5002 (5055 liters) - buffer tank;

* CAS-S 501 (475 liters), CAS-S 801 (740 liters), CAS-S 1001 (940 liters) - buffer tank with

heating coil for connecting solar collectors;

* CAS-B 501 (475 liters), CAS-B 801 (740 liters), CAS-B 1001 (940 liters) - buffer tank with

built-in stainless steel tank for domestic hot water;

* CAS-BS 501 (475 liters), CAS-BS 801 (740 liters), CAS-BS 1001 (940 liters) - buffer tank

with built-in stainless steel tank for domestic hot water and heating coil for solar

collectors.

— Buffer tanks of different dimensions, connections or larger volumes (up to 250.000 liters)

are made by the order.

CAS tank size selection proposal

— Pyrolytic(woodgasification)boilers:forevery1kWofboilerpoweratleast50liters

tank volume.

— Solid fuel boilers: for every 1 kW of power at least 30 liters of tank volume.

— Wood chip boilers: for every 1kW of power at least 12 liters of tank volume.

— Wood pellet boilers: for every 1kW of power at least 10 liters of tank volume.
