Vexve ACGE

Electrically operated loading group with electronic controller.

Characteristics

  • Factory pre-assembled compact loading group, which ensures trouble-free and quick installation to heat storage and heat source systems
  • The loading group provides a rapid rise in heat source temperature and storage loading starts automatically as soon as the operating temperature is reached, thus improving boiler efficiency and service life
  • At the initial stage of loading, rapid storage tank temperature stratification makes it possible to obtain heat energy very quickly after the start of the combustion
  • Automatic shut-off function closes the bypass line in the final stage of loading to ensure maximum loading the storage tank
  • Return temperature is steplessly adjustable from 0 to 95 °C with a single control knob
  • Ideal for use with water based fireplaces and stoves thanks to the easily adjustable return temperature, various heat sources can always be operated at optimum temperature
  • The charging group is easy to maintain and all wearing parts are easily replaced without the need to drain the water system
