Water quality - Import export

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.
