Accumulation tanks represent a vertical (or horizontal) welded structure, consisting of a cylindrical shell, upper and lower (left and right) elliptical bottoms, a fitting for supplying and removing the working medium and drainage of the system, as well as a fitting according to the project or at the request of the customer. Supports are welded to the lower bottom (shells - in horizontal design) for reliable installation on site.

Storage tanks are used as heat or cold accumulators, buffer tanks, water heaters. OPEKS -2 models are designed for: heating, accumulation of thermal energy in the form of hot water, hydraulic isolation of flows in the circuits of technological systems of industrial enterprises, hot water supply and heating systems, storage and transfer of excess heat received from the source (electric boiler, solid fuel boiler , heat pump, solar collectors, solar systems) with the ability to connect several sources of thermal energy.

  • increase in the service life of the heating system;
  • reduction of fuel consumption by 30-40%;
  • increase in the service life of the heating system;
  • reducing the risk of boiling a solid fuel boiler;
  • the ability to maintain a constant temperature;
  • combining different types of heat energy;
  • extension of the interval between boiler cleanings, easy installation into the existing heating system.

The tank / boiler dimensions are based on the standard model with a working pressure of 6 bar. It is possible to manufacture non-standard models with other parameters according to the agreed drawing.

To select the required storage volume, it is possible to combine several tanks into a cascade.

The storage tank is selected for the previously selected heat source and is calculated in such a way that it can accumulate all the heat generated by this source, or for the consumer of which it should be provided with heat generated before the time of heat consumption by a low-power source.

The priority in the selection of the capacity will be the source if its power or the time of heat input is limited.

The priority in the selection of the capacity will be the consumer, if it is required to cover a given heat load in a certain time.
The additional volume of water formed during heating to the maximum temperature is ~ 3.5% of the nominal volume of the container.
