VTZ Smart

ROOF FANS FOR OUTDOOR INSTALLATION

Solidity and performance for collective outdoor installations

The VTZ Smart fans range offers several models with capacities going from 345 m³/h up to 6 800 m³/h for the equipment of collective dwellings, offices, schools or other buildings. The VTZ Smart fans are designed for an outdoor installation, in terrace or on a pitched roof. Many connecting parts are available to adapt to different encountered cases. The VTZ Smart fans are characterized by their solidity and by an excellent energy efficiency, thanks to the use of high-performance electronic commutation motors and to an integrated pressure control device.

CONTACT-US

Low energy consumption: Electronic Commutation motor associated with an automatic pressure control device.

Solidity and reliability: metal design, made in Germany.

DCV compatible: integrated automatic pressure control device, optimizing the DCV performance.

Silent: acoustic foam on the entire envelope and sound trap available on request, optional.

Easy to install: many available adaptation parts, possibility of custom-built construction.

Easy to maintain: easy cleaning of blades after swinging the fan.

Electronic commutation motor for minimal consumption

The electronic commutation motor of the VTZ Smart roof exhaust fan offers an optimum consumption all the time. Associated to the pressure control device, it automatically adjusts the consumed power to the requested airflow, while maintaining a constant pressure. The motor integrates an electric cut of switch in case of high temperature and an output which can be used to diagnose a possible default.

A wide range of adapters for all cases

Aereco offers many adaptation parts made in aluminium or galvanised steel for pitched roofs and for the variable geometries of ducts. Specific parts can also be made custom-built on the basis of plans (contact us).

Pressure control device

A system of pressure control is integrated in the roof exhaust fan, allowing to define easily the pressure at working. Pressure measured by the integrated pressure gauge is displayed on digital screen. It is automatically regulated, optimizing the system working with demand controlled exhaust units.
