AirChange

FOR BETTER BREATHING

A modern home ventilation method

Automatic air circulation

Clean and fresh air in your space

Heat recovery and cost savings

Air recovery is a modern way of air ventilation and circulation aimed at maximum air cleanliness and freshness for your living space.

The Hevolta AirChange is a high-quality recovery system that always provides fresh air free from unwanted organisms, dust particles and odours from increased humidity thanks to a special 3-way filter.

What is heat recovery

Thanks to air recovery the outside air supply can be heated up with up to 90% efficiency.

Heat recovery means an energy recovery ventilation system. The Hevolta AirChange means that we can use the heat which would otherwise escape through windows to heat fresh air with up to 90% efficiency.

3-Way Filter

The outside air is filtered through a 3-way filter, which is a part of the heat recovery system.

Pre-filter

Removes large particles, dust, mosquitoes and other pollutants from the air.

Carbon filter

Absorbs formaldehyde, benzene and other harmful gases.

Hepa filter

Captures the finest particles such as pollen and other allergy-causing particles.

The Hevolta AirChange system can save 40 to 50% of energy compared to ventilation.

Healthy Air-ventilation

Systematic ventilation with a heat recovery unit prevents the formation of moisture and subsequent mould.

As most allergens are found in the air, window ventilation cannot ensure optimum air quality.

If the humidity in your house exceeds 60%, the amount of microorganisms in the air doubles.

If the humidity is too low, there is an increased risk of allergies and mucosal problems.

Mould at home can cause nausea and increased amount of diseases and allergies.

Inadequate ventilation leads to bad quality of sleep, disturbance in melatonin secretion.

How it works

1.

The exhaust air which is stuffy and polluted (high CO2, humidity, odour) is removed from the living space by the means of a fan in the unit.

2.

Exhaust air is heated to a selected pre-set room temperature by another heat source. Simultaneously, the fresh air from outside is supplied to the living space (using a second fan). This air has a low temperature in the winter.

3.

Indoor exhaust air and outdoor fresh air flow by using fans through a recovery heat exchanger, in which the heated exhaust air transfers the energy (heat) to the fresh air supplied. This is called heat recovery.

4.

In addition to heat recovery, the supplied and exhaust air is also filtered so it doesn’t contaminate the indoor living environment with dust from the outside, while preventing dirt particles from clogging the ventilation duct and the heat recovery unit.
