Enamelled steel tank (WRAS)

Thanks to its considerable power, the coil cylinder represents an economical and high-performance solution suitable for use with all types of energy. It has been specifically designed to meet domestic hot water production and storage needs both in the residential and manufacturing sectors.

The presence of one or two coils makes way for several operating modes :

  •   One coil version (lower) :
    • Preheating from a renewable energy source.
    • Heating by a heat generator.
  •   Dual coil version (lower + upper) :
    • Recovery (lower coil) + backup (upper coil).
    • Heating with to coils (for maximum power).

An electric immersion heater can be used to provide additional energy. The DHW coil heat exchanger system is available in two different types of tank to meet all needs :
