Duco's ventilation systems

Introduction

1A. Ventilation system operation

A Duco Demand-Controlled Natural Ventilation System (DCNVS) is a ventilation system that provides healthy air quality

automatically*. Sensor readings ensure that the building is ventilated only when it is required (= demand controlled). This

ventilation system operates on the system C principle, which means that polluted air is extracted mechanically (using a

central extract unit) and fresh air is supplied naturally via window ventilators.

Depending on the components installed, your ventilation system will:

→ Maintain CO

As standard, ventilation operates only until the CO

→ Maintain humidity at an appropriate level

Excessively high humidity can lead to moisture accumulation or mould growth and health issues such as eye, nose, and

respiratory tract problems. The ventilation system is geared (as standard) to 60% relative humidity, the optimum.

→ Exhaust unpleasant odours

Using presence detection in a toilet for instance, the ventilation system ensures that rooms smell fresh by exhausting

polluted air.

Summing up, your Duco ventilation system ensures a healthy as well as comfortable indoor climate.

* Exception: Duco C System

Duco C System

All Duco Demand-Controlled Natural Ventilation Systems feature an automatic setting which is controlled by one

or more sensors. A Duco C System does not include any sensors and hence no automatic setting, which means

the system requires wholly manual operation.
