1.No pressure tank(match stand alone model)
85L Diameter420,15tubes
111L Diameter420,20tubes
166L Diameter420,30tubes
150L Diameter 470,20tubes
180L Diameter 470,24tubes
250L Diameter 470,30tubes
2.No pressure tank with copper coil heat exchangers(match with stand alone model)
2.1copper coil internal heat exchangers:
*HE material:10mmODx1.0mm copper pipe
*HE Max Pressure:6 bar
2.2One advantage of this system is that almost no water is introduced into the tank,so corrosion and scale buildup is almost totally eliminated.
3.Specifications:
*Inner tank:stainless steel(SUS 304 2B)
*Outer tank:stainless steel(SUS 304 2B)
*Insulating layer:55MM Foaming
polyurethane
*Sealing rubber:silicon rubber
