Demand Controlled Ventilation

Historically, MEV-units used to run continuously: 24 hours a day, 7 days a week. At a single set speed This was deemed to be “ok” so the energy losses were deemed to be small.

DUCO feels that this “old school”-way-of-thinking is a thing of the past and decided to go a step beyond the “normal” operation mode of a “traditional” MEV system.

DUCO offers true “on demand” solutions which result in true energetically optimised ventilation solutions:

To only ventilate, when necessary, where it is necessary and as long as it is necessary!

The DucoBox Silent has an internal humidity sensor that detects high humidity and increases the performance until the set level is reached again

It is also possible to install a CO2 box sensor inside the DucoBox Silent UK

With an “on demand” DUCO-system, the occupant can always be assured to breathe the best possible indoor air, whilst also using the least amount of energy! DUCO brings you the SMARTEST ventilation solutions!

Silent Plus Kit

The Silent Plus Kit provides additional acoustic damping of up to 3 dB(A)!

The kit consists of three acoustic composite foam pads and three acoustic caps that are placed into the predesigned inserts inside the unit 

Quiet-Vent adaptors

The Quiet-Vent 125 to 90 adapters allow you to connect the 90mm radial pipe directly to the unit avoiding the use of a distribution box that will provide many benefits over using solid rigid ducting

Up to 7 number 90mm radial ducts can be used on the unit

This option will reduce installation time over solid rigid duct, reduce cost as there is no need for a distribution box, and comply with the latest building control requirements 

Fault Indicator

With the optional wall mounted fault indicator, you can be notified by colored indicator light when a fault is detected (max one per unit) 

Boost switch

A boost switch will allow the user to manually increase or decrease the speed, there is a manual 2 speed and 3 speed switches available

Only one boost switch is recommended per unit and if the speed is set to high it will override any sensors and remain at that speed till manually reset to a lower speed

A boost switch is required to commission the unit
