The Calpak Mark 4 Solar Heater provides high efficiency and durability over time for real economy. Calpak uses cutting-edge technology, the best quality materials and innovative ideas such as the all-aluminium support system for easy installation, high aesthetics and unparalleled durability.
Aesthetics
Minimalist aesthetics with attention to detail, safety and functionality. The Mark4 design is protected by a registered European industrial design right.
Innovative features
The first solar panel with an all-aluminium mounting system for easy installation, high aesthetics and unparalleled longevity.
The production method of the collector is truly subversive. The glass and aluminium backing are pressed to form a robust whole with a very clean appearance and weather resistance.
The double-wall anodised aluminium frame is a global innovation that provides great strength and better insulation, and therefore better performance.
The closed circuit of the heat exchanger of the tank has been completely redesigned, after many laboratory studies, in order to achieve the fastest possible heating of the water from the collector.
High performance
The Mark4 collector gives the system really high performance. It has a Tinox high-selective absorber (e<3,5%) with one copper tube per 10cm and ultrasonic welding. The glass is low iron with high permeability (T>91,5%).
The thermal loss coefficient of the collector is one of the best officially measured in Europe (a1=3.56). The certified efficiency of Mark4 collectors is 946 kWh/m²/year ensuring energy sufficient to cover 90% of your hot water needs.
