VIC Domestic hot water storage tanks Series BU

General: The accumulator-water heaters of the BU series are produced with an accumulator volume of 1,000 to 50,000 liters, for operating pressures of 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. The containers are produced in St. 37.2 (S235JRG2), HII (P265GH) black, in stainless steel 1.4301 and 1.4571.

Heat exchanger:  All water heaters are equipped with one or more filler necks, which serve at the same time as a cleaning and inspection openings and as receptacles of the U-tube heat exchangers. The U-tube heat exchangers can be pulled out and are made from smooth pipe 18x1 stainless steel AISI 316L(Material No.1.4435). Pipe mounting plate produced of stainless steel AISI 316 (Material No.1.4401), in accordance with D17.100. filler necks

Corrosion protection: As corrosion protection, the water heaters can be galvanized up to 10,000 liters or be provided with an epoxy inside coating in all sizes. The coating is implemented with subsequent application on sandblasted surface in several single layers, and is suitable for operating temperatures up to 95°C, 120°C in the short term (steam-jet disinfection).

Insulation: The insulation is implemented in the works and is applied directly onto the water heaters. A PU soft foam insulation 21 kg/m³ is supplied as insulation, with additional weatherproof jacketing.
Or insulated with mineral wool lining and cased with a sheet-metal jacket for the protection of the insulation.

Installation: All water heaters of the BU series are supplied in vertical and horizontal design implementation.

The manufacture of our water heaters (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.
