An unobtrusive talent

Recirculation

Recirculation mode is the most energy-saving operating mode. The air is cleaned by an odour filter and directed back into the room. The room temperature is not altered. It is also simple to implement, because wall penetrations and exhaust channels are not required. Due to their large volume, berbel charcoal filters are especially efficient at odour-binding and absorb up to 95% of bad smells. A further advantage of the berbel recirculation filter: only the proactive carbon needs to be changed – not the entire filter – and it only needs to be replaced every two to three years depending on how hard the filter has to work. The berbel refill pack is available for a cost-effective and environmentally friendly replacement.

Exhaust air

Exhaust air directed outside the building is particularly effective when it comes to the removal of odours, fumes and the moisture that results from cooking. It is advisable to use a berbel automatic wall sleeve to minimise heat loss. This seals and insulates the pipe outlet on the façade when the extractor hood is switched off. The planning of the exhaust air flow path should be optimised, since this positively influences the efficiency and smooth running of the hood. The appropriate duct material for this can be found in the exhaust air accessories section.

Hybrid

Combine the benefits of both exhaust air mode and recirculation mode. With the berbel EcoSwitch you can respond flexibly to your needs depending on cooking and weather conditions by using the EcoSwitch button on your berbel extractor hood to switch between energy-saving recirculation mode in winter and particularly effective exhaust air mode whenever you need: for instance during fast browning or throughout the summer months. In addition to the berbel extractor hood with EcoSwitch you need the following system components for this:

• berbel wall box
• optimised flow for extraction ducts
• berbel hybrid filter
