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.
