Renovation
Reduce energy use and decrease CO2 footprint
with upgrading your ventilation.
Benefits
Passive and extract ventilation systems lack energy recovery, which leads to substantial losses of valuable heating and cooling energy. Modern Heat Recovery Ventilation (HRV) systems are capable of recovering more than 80% of this energy, significantly lowering overall energy consumption.
- Improved indoor air quality & comfort
- Improved energy efficiency
- Balanced indoor humidity
- Reduced carbon footprint

Replacement units
to replace old heat recovery ventilation
Renovation units designed to replace old ventilation systems. Easy and quick to instal as they fit directly in place of the old units such as ILTO or BACHO Minimaster.
- Better air quality
- Lower sound level
- Saves energy and money
- Integrated demand control (RH,CO2,VOC, C)
Renovation unit

Renovation success
Our customers have significantly reduced energy costs and carbon emissions — all while benefiting from improved indoor air quality.
Carbon footprint in focus
146 student apartments, Finland.
Student housing from the 1990's had only mechanical extract ventilation, causing significat loss of heat energy. With heat recovery installed in the 146 apartmetshousing achieved a signiantly lower carbon footprint.
Comfort with automation
1970's detached house, Finland
The Karisto family from Espoo considered repairing their old ventilation system, but concluded that investing in a new one would ultimately be more cost-effective. The new system saves thousands of kilowatt-hours of energy — not to mention the improved indoor air quality and comfort they achieved with demand control.

7,000 kWh savings per year
A complex of detached dwellings, Finland.
With heat recovery and demand-controlled ventilation, the apartments can save up to approximately 7,000 kWh of energy per year.
