Heat accumulators of series VTN are made of food-grade stainless steel of grades AISI 304, 316 and 321, and thus is achieved high level of corrosion protection. The smooth inner surface prevents the formation of scale on walls of the tank and heat exchangers. So this product is ideal for use at sites with high sanitary requirements for water quality (food industry, facilities of hotel and restaurant complex, hospitals etc.).

Heat accumulator VTN-1 is equipped with two fixed heat exchangers that allow to use the tank in bivalent systems. Lower heat exchanger is usually attached to low-temperature heat sources (solar collector, heat pump, heat recovery installations), and and upper, in turn, to high-temperature (gas, electric boiler) and is used to finish heating of water to the required temperature.

The feature of heat accumulator VTN-2 is the use of built heat exchanger at the bottom of the tank to connect any source of heat. Thus, this model is ideal for monovalent DHW systems.

Heat accumulator VTN-2 PLUS is equipped with heat exchanger of increased area, which helps to effectively use low-temperature heat generators in DHW systems, in which the heat source is condensing gas boiler, heat pump or solar collector.

Heat accumulator VTN-3 is used as a storage tank of hot or cold water. VTN-3 works perfectly in systems turbo-boiler, with well-used effect of layered accumulation of hot water (from top to bottom).
