ATSx Hot Water Tanks

Stainless Steel Buffer Vessels and Indirect Hot Water Tanks for DHW Applications

ATSB, ATSI, ATST, ATSH, ATSR

Stainless Steel ATSx Hot Water Tanks

  • Corrosion-resistant stainless steel construction
  • Vessels from 200 to 1000 litres
  • Rated 10 bar as standard
  • Storage tank, single coil, and twin coil options 

The Adveco ATSx hot water tanks offer a range of models from 200 to 1000 litres at 10 bar as standard.  This range of stainless steel vessels is suitable for use as hot water buffers, and single, or dual coil calorifiers as required for the application.

The range consists of three types of vessel, differentiated by the number of internal heat exchange coils included as standard.

ATSB are a range of high-quality buffer vessels supplied without any internal heat coils. The ATSB features multiple connection points as well as a clean-out access flange. Serving as a buffer vessel only, the ATSB can be used to expand the dump load capacity of a water heating installation.

The ATSI, ATST, ASTH, ATSR water heaters are designed to be used with indirect heat sources as calorifiers across a range of DHW installations exhibiting smaller demands, but requiring more than six bar pressure.

ATSI feature a single internal fixed heating coil at low level.

ATST  feature two internal fixed heating coils, at low and high level.

ATSH feature a single internal high capacity fixed heating coil at low level for use with a high powered indirect heat source.

ATSR feature two internal fixed heating coils with an increased surface area designed for use with renewable heat sources, at low and high level.

All models feature multiple connection points and a clean-out access flange.

The ATSx Range is constructed from corrosion-resistant AISI 316Ti and 316L stainless steel making it the ideal choice for soft water areas in the UK.

For hard water areas where scale build-up can prove problematic, Adveco can specify 9kW and 12kW electric immersions with a uniquely low 6W/cm2 heat intensity. Without detrimental effect to the demands for hot water, this slows the potential for scale build-up making the ATSx range a resilient option for projects whether water is naturally hard or soft.
