Vexve ACG

Thermostatically controlled loading group

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
  • The return temperature can be adjusted using exchange thermostats
  • The charging group is easy to maintain and all wearing parts are easily replaced without the need to drain the water system
