Construction of heat accumulators of model VTA/N “Tank in tank” implies the presence in carbon steel tank the stainless steel tank. Due to this construction, heat accumulators of this series combine all advantages of accumulation boiler and storage tank. This model is designed for simultaneous use in heating systems, and preparation and accumulation of hot water.
The inner tank is made of high quality food-grade stainless steel. Its main difference is the construction of wall of the tank, which is made waveform for increased resistance to external pressure, increasing of heat exchange area, and this construction allows self-cleaning of scale due to thermal extensions.
