The Pro-Clean or Pro-Heat tank families are multifunctional stratified tank systems made of steel (S 235 JR). Stratified solar charging is via an external spherical exchanger (gravity circulation principle). The tanks are fitted with inflow absorbers on the boiler/heating side, ensuring optimum retention of stratification.
The Pro-Clean and Pro-Clean 2 corrugated pipe stratified tanks are combination tanks fitted with a corrugated stainless steel pipe (1.4404) allowing for an integrated, hygienic preparation of hot water within a continuous heating process. The PC 2WR is designed for high consumption of hot water due to its two corrugated pipes.
The Pro-Heat stratified tank is a pure backup tank. A freshwater module is additionally required for the optional preparation of hot water.
