All Helty ventilation units are decentralised HRVs with dual continuous flow and counter-current crossed air flows. Stale air, saturated with humidity and CO2 , is extracted from indoor areas and forced to flow into the heat exchanger where -- without contact between the two flows -- its heat is transferred to the incoming air flow simultaneously pumped in from outside.

Wall Mounted HRV

Helty FlowEASY-UV is an automatic air exchange and sanitising technology that integrates the advantages of a HRV with the sterilising and microbe-killing power of UV technology. In addition to the dual filter, this unit incorporates a 259 nm UV-C lamp which uses ultraviolet radiation to combat viruses and volatile substances to purify the air. The high level of purity of the intake air and the abatement of pollutants ensures a combined action against viruses, bacteria and contaminants, improving the healthy quality of the confined environment.

Built in Recessed MVHR

Helty Flow40 is a decentralised solution built into masonry; it is an ideal solution for renovation contexts and energy re-qualification projects. The HRV becomes invisible, combining excellent air renewal performance with no footprint: Flow40 does not require ducting or false ceilings and leaves only the cover visible, available in a white pre-painted metal version or in white or black Plexiglas.

FLOW Manhatten

Flow Manhattan reinvents point-wise ventilation for individual environments, offering designers and buyers a solution in which the HRV unit is camouflaged in the external wall insulation. The air flow grilles, fixed to the face of the window hole edge, are designed to protect the architectural profile of the building and do not visually impact the facade.

FLOW M800

Helty FlowEASY-UV is an automatic air exchange and sanitising technology that integrates the advantages of a HRV with the sterilising and microbe-killing power of UV technology. In addition to the dual filter, this unit incorporates a 259 nm UV-C lamp which uses ultraviolet radiation to combat viruses and volatile substances to purify the air.
