ΗΛΙΑΚΟΣ ΘΕΡΜΟΣΙΦΩΝΑΣ CALPAK MARK 5 160Lit / 2.1m2 ΔΙΠΛΗΣ ΕΝΕΡΓΕΙΑΣ

Aesthetics

• Minimal 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-aluminum support system for easy installation, high aesthetics and incomparable longevity
• The production method of the collector is truly revolutionary. The glass and aluminum back are pressed to form a robust unit with a very clean look and weather resistance.
• The double-wall anodized 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 water used 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 low iron with high permeability (T>91.5%).
• The heat loss coefficient of the collector is one of the best that has been officially measured in Europe (a1=3.56). The certified performance of the Mark4 collectors is 946 kWh/m²/year ensuring energy sufficient to cover 90% of hot water needs.
