The envelopes of energy-efficient buildings become more and more impermeable so that controlled housing ventilation systems combined with geothermal heat exchangers can no longer be dispensed with. Such systems result in the highest residential standards as they provide permanent fresh air supply without any losses on airing.

Thanks to its high quality and excellent properties POLO-KAL NG for many years has been the optimal solution for modern ventilation systems with geothermal heat exchangers. This is how POLO-KAL NG contributes to making living even more comfortable and to increased energy efficiency.

Manifold references
Many modern buildings, above all low-energy and passive houses, have been equipped with controlled housing ventilation systems and geothermal heat exchangers using POLO-KAL NG.

Just one example is the low-energy detached house of the Hager family in Furth, which was awarded the designation "exemplary building" by the Lower Austrian government in 2011. This building project was equipped with POLOPLAST's sound insulating plumbing and controlled housing ventilation.

Low-energy detached house of the Hager familiy

In general, the Hager project attached much importance to MEP:
a heat pump for the heating and hot water system, deep geothermal wells, underfloor heating / cooling, a controlled housing ventilation system, sound insulating domestic waste disposal, a rainwater cistern for garden watering.

POLO-KAL NG used in POLO-KAL NG KWL

The "Haus W. Nordsiedlung“ project in Waidhofen/Thaya was awarded the Lower Austrian timber construction prize 2011. For this building project a POLO-KAL NG EWT geothermal heat exchanger was fitted.

POLO-KAL NG EWT

The advantages of POLO-KAL NG KWL:

Perfect air quality
Reduced dust precipitation and easy cleaning: round pipe profile and smooth inner layer.

Minimum energy demand
Low flow resistance values: smooth inner surfaces with precisely fitting leakproof connections.

Easy installation
in any position thanks to high ring and axial rigidity values and the precise push-fit socket system: can be embedded in ceiling concrete, as well as fitted on floors, in partitions, shafts and wall apertures.

Ease of maintenance & unproblematic cleaning
Circular pipe profile: Inspection lids in the manifold provide maintenance of main pipes from a central location.

Wide range of accessories
The complete basic equipment: Suction hoods for geothermal heat exchangers, antimicrobial filter cones, manifolds, air outlets, flow regulators, flexible linking, etc.

Extendable
Perfectly accurate transitions allow POLO-KAL NG to be combined with other systems.
