Calpak Mark 4 160lt/2.6m² Glass

  Aesthetics

• Minimal aesthetics Pay attention to detail, safety and functionality. The design of the Mark4 is protected by a protected European industrial design right.

  Innovative features

• The first solar’s support system made entirely of aluminum for easy installation, high aesthetics and incomparable longevity. The collector production method is really subversive. The glass and the aluminum back are pressed to form a solid whole with a very clean look and resistance to weather conditions. The anodized double-walled aluminum frame is a global innovation that provides high strength and better insulation, therefore better performance. The closed circuit of the tank heat exchanger has been completely redesigned, after many laboratory studies, in order to achieve the fastest possible heating of the waste water by the collector.

  High performance

• The Mark4 collector gives the system a 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 lowiron high permeability (T> 91.5%). The coefficient of heat loss of the collector is one of the best that have been officially measured in Europe (a1 = 3.56). The certified efficiency of Mark4 collectors is 946 kWh / m² / year ensuring energy that is sufficient to cover 90% of your hot water needs.
