Accumulating tanks are a vertical (or horizontal) welded structure, consisting of a cylindrical shell, an upper and lower (left and right) elliptical bottom, a fitting for supplying and discharging the working medium and draining the system, as well as a fitting according to the project or according to customer's instructions. Supports are welded to the lower bottom (shells - in horizontal version) for reliable installation at the place of operation.   

      Accumulating tanks are used as heat or cold accumulators, buffer tanks, water heaters.   OPEKS-2  are intended for: heating, accumulation of thermal energy in the form of hot water, hydraulic decoupling 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 a source (electric boiler, solid fuel boiler, heat pump, solar collectors, solar systems) with the ability to connect several sources of thermal energy.

  • increasing the life of the heating system;
  • reducing fuel consumption by 30-40%;
  • increasing the life of the heating system;
  • reducing the risk of boiling solid fuel boilers;
  • the ability to maintain a constant temperature;
  • combining different types of thermal energy;
  •  increasing the interval between boiler cleanings, simple installation in an existing heating system.

Characteristics of the upper heat exchangerUnit ch1000


 The dimensions of the tank/boiler are for 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 containers into a cascade.

The storage capacity is selected for a previously selected heat source and calculated in such a way that it can accumulate all the heat generated by this source, or for the consumer of which it is necessary to provide heat generated before the time of heat consumption by a low-power source.

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

The priority in the selection of capacity will be the consumer, if it is necessary 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 tank.
