Single coil heat exchanger VTC1
Double coil heat exchanger VTC2
Storage tanks with fixed coil heat exchangers for both circuits for use of heating and solar system. The long large
surface of coils allows efficiently spread of energy along the tank producing domestic hot water and avoiding cold
zones.The base of enamel is, free boron and silisium and hygienically complies with European standards.

Electrical water heater EVT
In some applications where the electrical energy is the only possible or preferable source for water heating,
EVT electrical vertical water heaters standard capacities up to 3000Lit are used with the following specifications:
- Material of tank Low carbon hot rolled steel plate DIN EN 10111-98 DD 11
- Internal protection Enamel coating, thickness 200µm-250µm
- Working pressure 10 bar
- Testing pressure 13 bar
- Max working temp 95°C
- Extra Protection Magnesium rod
- Insulation Free CFC Polyurethane, density 44 kg/m³
- Insulation thickness 50mm PU for 200-600 lit 80mm Foam Soft PU for 800-3000 lit
- Outer jacket Artificial Leather Cover, painted steel cover upon request
- Electrical heating elem. Stainless steel, capacity (Kw) upon customer’s request
(capacity range 2….45Kw) 230 - 230/380V
Features:
The control box is fixed at the water heater, made of Polyester with degree of protection IP54. Three electrical heating
elements are operating by electro-magnet contactors signal from thermostats or individually by manual external
disconnecting switches. The control box contains one main input fuse, safety thermostats and power pilot lights.
