Controlled residential ventilation

Mono tube ventilation system ultraSilence ELS EC

Now also with energy-saving EC-technology: The mono tube ventilation system ultraSilence ELS from Helios has impressive benefits for the ventilation of interior bathrooms and WCs in residential units, hotels and other buildings prescribed by DIN 18017-3.

Space-saving: A central riser duct spanning more than 20 storeys with the smallest possible cross-section saves money and creates usable living space.

Cost-effective: Low material use and quick and easy installation result in manageable costs and time required.
Energy-saving: The ultraSilence ELS devices reduce the need for ventilation heat and therefore contribute to energy-savings when it comes to heat.

Central ventilation system ZLS

ZLS-DV EC is the ideal central ventilation system in multi-storey construction according to DIN 18017-3. Humid, polluted air is extracted in line with requirements. At the same time, the pressure-controlled controller integrated in the fan guarantees that a set negative pressure is maintained. Thus, the planned air flow volume remains unchanged in all other rooms. Energy-saving EC technology with highest efficiency, even for controlled operation, and up to 50 % energy saving in comparison with conventional motors.

Central ventilation box ZEB

The powerful energy-saving box – ideal in low energy houses or in multi-storey buildings. Passive and low energy houses set the standard with regard to the insulation and impermeability of building envelopes. The compliance with provisions must be proven by a special test upon a building inspection. In order to comply with the Energy Savings Ordinance (EnEV), ventilation units with highest efficiency levels must be used in full load and controlled operation.
