Heat accumulator tank - Import export

The heat accumulator VТА/V-1 is assembled from two different tanks in size, in the space between them is created an average vacuum (0,1 mBar) and filled with insulating powder (λ=0.007-0,01W/m∙K). Compared to traditional heat accumulators, the VTA/V-1 minimizes heat loss for effective heat storage. Its powder-vacuum insulation (PVI) replaces the standard 100cm of urethane-foam isolation. PVI’s thermal conductivity ranges from 0.007 to 0.01W/m∙K, significantly lower than rock wool (0.06W/m∙K) and urethane foam (0.04W/m∙K). The VTA/V-1 occupies similar space to traditional models. Key benefits include: — capacity of 2000-10000 liters; — possibility outdoor installation; — underground installation capability; — up to 10 times better thermal insulation in comparison with analogues; — absolute insulation moisture resistance; — long-term heat retention(ideal for heat pumps and solar collectors); — stable temperature stratification of heat carrier through the system of stratification.

The VTA/N "Tank in Tank" heat accumulator features a stainless steel tank inside a carbon steel tank. This design combines the benefits of both a storage tank and a heat accumulator, allowing for simultaneous use in heating systems and hot water storage. The inner tank is made from high-quality food-grade stainless steel with a wave-shaped wall for increased resistance to pressure, improved heat exchange area, and self-cleaning through thermal expansion. The VTA/N-1 model includes a carbon steel heat exchanger at the bottom for optional connection to solar collectors or other heat sources (heat pump, gas, solid fuel, electric boilers). The VTA/N-2 model lacks a heat exchanger, allowing direct connection to any heat generator. The VTA/N-1-SOLAR PLUS model has an enlarged inner tank partially placed within the heat exchanger, improving efficiency with low-temperature heat sources.
