Forced Circulation Systems
Using the cutting-edge technology of our new smart factory we took our premium solar collector line to the next level. The M5, whilst maintaining the unique structural sturdiness of its predecessor, raises substantially its performance and is solar-keymark certified as one of the most efficient solar thermal collectors in the market (η0= 80%)
The Architect’s Choice The sturdy frame of the M5 allows it to be supported by two aluminium sticks, offering a neat installation. Moreover, the M5 remains very efficient even at very low inclinations thanks to its outstanding performance attributes.
1. Double-wall alumimium profile 2,4mm This frame offers increased durability and enhanced insulation. 2. High performing absorber Made of a dense harp, with 12 laser-welded copper risers, and 0,5mm full plate ultra-selective surface. 3. Boltless construction for clean looks The glass and aluminium base are compressed so as to form a sturdy totality with a prism-like facade. 4. Integrated support attachments for ease of installation and universal compatibility This collector can easily and safely be adjusted on different types of inclined or flat roof supports.
Fresh Water Ultratanks
Ground-breaking technology for fresh hot water
Optimizing the heat transfer process had always been a major challenge for our R&D department. Transmission of thermal energy from the energy source to the storage tank and from there to consumption traditionally suffered from substantial heat losses that affect both efficiency and the ultimate operational cost of the hot water system. The intelligent X-flow technology developed and patented by Calpak overcomes the issues of thermal losses and low efficiency rates typical in conventional heat exchangers. The Calpak X-flow ultratank ensures exceptionally fast and efficient thermal exchange between the closed and open circuits resulting in at least 25% energy savings compared to a conventional storage or fresh water tank in any given hot water installation.
What is the Calpak X-flow ultratank*?
The Calpak X-flow is a fresh water tank of very high efficiency. It can be charged by any available energy source (e.g heat pump, gas or diesel boiler, solar collectors, electrical element). It stores the energy in its buffer tank and can instantaneously transfer this energy to the fresh water heat exchanger quickly heating up the domestic water to the desired temperature. The energy stored in the buffer tank can also be used for space heating or any other similar use that requires thermal energy.
