Product Data Sheet va-Q-shell DESCRIPTION va-Q-shell is a customized, rigid shell insulation system for heat storage tanks. Its purpose is to increase the energy efficiency of tanks to a label rating of A and A+ according to the EU regulation 812/2013. The insulation consists primarily of two PU half shells with integrated vacuum insulation panels (VIP). The shell parts are assembled via a tongue-and-groove system. Cut-outs for piping, inspection ports and other connections are also provided. Baseplates or fixation points for technical devices like displays, sensors or external heat exchangers are available on request. va-Q-shell can be individually adapted for variously shaped hot water tanks.
