High Gain Indirect
Single Heat Exchanger / Vertical Floor Standing
- Made from high grade AISI 444 stainless steel, extremely resistant to pitting corrosion
- All welds are butt welded
- Made by high quality welding process TIG (GTAW), eliminating the possibility of crevice corrosion
- The complete tank is pickled and passivated both inside and outsider
- No sacrificial anodes required
- Thick insulation polyurethane foam layer - λ = 0,022 W/mK
Low Temperature heat exchanger
The low temperature heat exchangers contribute to increase the efficiency of heat pumps when producing domestic hot water
Double or triple spiral coils can bring the heat transfer
surface from 1,8 sqm up to 7 sqm (in tanks up to 500L)
Along with high performance, this will bring high durability to the heat pump (as it will enable the heat pump to work according to the optimal regime)
