The X-Flow fresh water ultratank is the result of a unique technology by Calpak in hot water tanks. Achieving an optimal management of energy was one of the biggest challenges of our company’s R&D department. The ground-breaking technology of our new fresh water tank, which is protected by international patent, ensures extremely fast and efficient conduction of heat.Your benefit, according to official laboratory measurements, is an extra energy saving of 25% when compared to a conventional tank! Available in tanks of 500-2000L and combined with heat exchangers with outflow of 1500 L/h, 3000 L/h and 4500 L/h at Δt=1!

• Top energy efficiency of the fresh water heat exchanger 99%.
• Minimum divergence between load and supply temperature (Δt=1).
• Prevents the development of the Legionella bacteria.
• Great life span with minimal maintenance costs.
• Prompt heating of domestic water to the desired temperature.
• Constant supply of hot water at the desired temperature.
• Combined ideally with heat pumps and solar collectors
• Easy installation and replacement of existing tank
• Easy extensibility to other auxiliary sources
• Suitable for residential and commercial projects as well as hotels

The solar water heater Prisma combines a truly resilient water tank with the high performing Prisma collector, producing ample hot water for many years. The production is fully automated with new robotic systems that are centrally controlled through 5G technology and AI algorithms.It ensures absolute standardization of the production process and, therefore, the assurance of high quality. Available in models of 160 L, 200 L and 300 L.

Mark5

Calpak has designed from the ground up a thermosiphonic system that addresses the most important issue: the provision of exceptional performance and thereby enhanced financial savings. With our many years of experience we thought outside the box and dared to pioneer. In so doing, we remain committed to safeguarding the traditional values of our products, namely sturdiness and durability because we understand that only by doing so, does it make sense to invest in a solar thermal system. Calpak uses the latest technology, raw materials of the highest quality and the state of the art production capabilities of its new factory.

Mark5 is the first thermosiphonic system with an aluminium support structure for easy installation, superior aesthetics and incomparable durability. Also the collector’s production method is truly innovative. The glass and aluminium base are compressed so as to form a sturdy totality with a prism-like façade. The anodized double walled aluminium profile epitomizes our innovation in offering increased durability and enhanced insulation. Mark5 is Solar Keymark certified as a wholesystem.

M5-210 / M5-260 / M5-260H / M5-300 / M5-300H

M5 collector redefines the standards of sturdiness and durability with its innovative characteristics. Double wall-frame aluminium profiles offers increased durability and enhanced insulation (very low thermal losses). This unique profile is combined with a high selective Tinox full plate absorber and a 3,2mm tempered low iron ( >91,5%) glass. The glass and aluminium base that are compressed in a boltless construction form a sturdy totality with a prism-like facade. This collector can easily and safely be adjusted on different types of inclined or flat roof sup­ports. In addition, its specially designed elastomeric and engineering plastic parts ensure complete sealing protection. With 5 different models from 2 sqm up to 3 sqm it can meet the most demanding requirements for any kind of project.

• High selective type full plate collector (Tinox, e<3,5%)
• Double wall aluminium profile frame
• Boltless frame
• Laser welding
• Thick rock wool insulation
• 3,2 mm low-iron tempered glass
• Certified under Solar KeyMark/SRCC
• Compressed structure
