VIC is green technology for refrigeration, air conditioning and heating systems

VIC Heating / CHP water buffer store tanks Series SP

The SP container series was developed specially for use as buffer accumulators with layering function in loading and final-loading operation, and simultaneous hydraulic switch points for cogeneration systems and heating plants.

The hot/warm water layer accumulators of the SP series are produced to order for hot-water and cogeneration systems with an accumulator volume of 500 to 50,000 liters, for operating pressures of 3, 6, 10 and 16 bar.
All layer accumulators are calculated in accordance with the Pressure Vessel Ordinance (wall / floor thicknesses), taking as a basis a calculation temperature of 120°C.

Dependent on the respective case of application, the layer accumulator can be provided with various items of mounted equipment.
In order to ensure trouble-free layering within the accumulator, the nozzle tubes with 4 connections, which were developed by us, are used (secondary / primary system).
In case of layer accumulators with 2 connections or several connections (inlet / outlet), inlet pipes are employed and in addition perforated plates (correctly dimensioned, dependent on the volume flow), welded into the container bottoms.

DN200 flanges (as a hand hole) and DN 500 flanges (as a manhole) are used as inspection openings. Oval inspection openings are to be dispensed with due to the type of insulation used.

As corrosion protection, the layer accumulator can be provided with an inside coating on epoxy base. The coating is applied subsequently on the sandblasted surface in several single layers. The coating is suitable for operating temperatures up to 95°C, and 120°C in the short term (steam-jet disinfection).
Internally-coated layer accumulators are basically to be equipped with inspection openings.

The manufacture of our layer accumulator (also in special dimensions, as well as our standard sizes), is basically not implemented until an authorized construction drawing has been provided by the orderer.
