The VTN series heat accumulators are made from food-grade stainless steel (AISI 304, 316, 321), offering excellent corrosion resistance. Their smooth inner surface prevents scale formation, making them ideal for applications with strict water quality requirements. The VTN-1 model has two fixed heat exchangers for bivalent systems. The lower exchanger connects to low-temperature sources (solar collectors, heat pumps), while the upper connects to high-temperature sources (gas, electric boilers) for to finish heating of water to the required temperature. The VTN-2 model features a built-in lower heat exchanger for monovalent DHW systems. The VTN-2 PLUS has a larger heat exchanger for efficient use with low-temperature heat sources like condensing gas boilers, heat pumps or solar collectors. The VTN-3 model serves as a storage tank for hot or cold water and is ideal for "turbo-boiler" systems, utilizing layered heat accumulation from top to bottom.

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.

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 heat accumulators in this series are made from structural steel S235J, with an inner bioceramic polymer coating containing biocides. This flexible coating prevents cracks from temperature changes and deformations, while biocides protect against pitting corrosion, extending the product's lifespan. These tanks store hot water for systems in hotels, restaurants, residential buildings, and more. Depending on the model, they come with one (VTP-1), two (VTP-2), or three (VTP-3) flanges for mounting heat exchangers and can work in "Turbo-boiler" systems. Models VTP-4 and VTP-5 have a built-in bottom heat exchanger for monovalent DHW systems, with VTP-5 is the ability to mount an additional upper flange exchanger. VTP-6 features two fixed heat exchangers for bivalent systems, with the lower connected to low-temperature sources (solar collectors, heat pumps) and the upper to high-temperature sources (gas, electric boilers). An inspection flange is provided for maintenance.
