Combi-buffer tank - Import export

Combi tanks are manufactured together diesel chamber and a hydraulic oil chamber. On request, the Optima fuel tanks can also be equipped with a double partition wall. This offers additional safety, especially on construction sites.

For several fields of energy technology we produce heat storage and buffer tanks according to individual costumers´demands. We offer optimized statically design calculation for your requirements, from small installations to vessels with capacity of 600m³, optional with insulation in our factory or on site.

The VTA series buffer tanks work with various heat sources (solid fuel, gas, electric boilers, solar collectors, heat pumps) to store and use heat for heating and hot water supply (HWS). The design includes heat exchangers made of stainless and carbon steel, with the option to install thermoelectric heating elements. In models VTA-1 and VTA-2, the stainless steel heat exchanger is located at the top for domestic hot water. The carbon steel heat exchanger in VTA-1 and VTA-3 is at the bottom, ideal for solar collectors or low-temperature systems. The VTA-1-SOLAR PLUS features an enlarged stainless steel exchanger part of which is located directly in carbon steel heat exchanger, improving DHW performance. Models VTA-4 and VTA-4-ECONOM lack exchangers, perfect for use in conjunction with solid fuel boilers. A distinctive feature of VTA-4-ECONOM is a simplified construction to minimize the number of connecting pipes and absence of flange, which reduces the cost of product.
