Aluminium profiles that harvest heat from air, wind and sun.
Available for licence.
A design portfolio for manufacturers who already work in aluminium.
Posts, beams and façade elements in extruded aluminium. Connected, they become the heat source of a water-to-water heat pump.
No outdoor unit. No borehole. Nothing to hide behind a wall.
In a warm climate the same structure can work the other way round and release heat, so the pergola helps cool the house.
Ten EU design applications, filed with EUIPO on 15 September 2026. Holder: Kael Holding B.V.
Four markets. One portfolio.
For manufacturers of aluminium pergolas and louvred roofs in Southern Europe.
For pool builders and pool-house suppliers who want a longer season without a noisy unit.
For fence and screen manufacturers. Above ground, along the plot, where drilling is not an option.
For façade and cladding systems. A half profile mounted against the wall.
Your brand. Your extrusion partner. My designs.
I license the designs white label. You integrate them into your own product line, under your own name, made by the extruder you already work with.
The licence covers the EU designs and the know-how behind them. The designs themselves are unpublished, so you see them after a mutual NDA.
The working principle has been measured. Cooling has not.
A proof of principle as heat source for a heat pump has been built and measured.
Cooling in a warm climate follows from the same physics and has been calculated. It has not been measured yet.
There is no product on the market yet. That is why a licence is open now.
Tell me who you are and what you make. You receive a mutual NDA, and after signing the ten designs, the applications and the licence outline.
