Vertical probe

Vertical probes (vertical collectors) are used to collect heat from the earth. They are manufactured of HDPE PE100 SDR17 pipes with following diameters: 32mm, 40mm, 45mm, 50mm and 63mm in combinations as: 2x32mm, 4x32mm, 2x40mm, 4x49mm, 2x45mm, 4x45mm, 2x50mm and 4x50mm. Collectors with diameters 40 and 45mm are manufactured as smooth or riffled inside, all the others are just now manufactured only as smooth inside. The collectors are winded into coils of any length – the only length limitations are the coil dimentions.
