Calpak Prisma 160/2.5

The Calpak Prisma 160/2.5 Dual‑Energy (Glass) solar water heater is a high-quality system designed for reliability and efficiency. Calpak uses the specialized Prisma® collector, which incorporates BASF’s Colofast® polymer — a material that provides high strength, rigidity, and excellent bonding with metal and glass.

The tank is made of steel (DC‑03 type) with internal protection against corrosion through enamel coating (glass) and an additional magnesium anode for enhanced durability.

The tank insulation is made of eco-friendly polyurethane to reduce thermal losses.

The dual-energy function means that, in addition to solar heating, there is an electric heating element (3.5 kW, inox) to support heating when solar energy is insufficient.
