Introducing VEX4000

Design your ventilation system as you want

With capacities from 1,050 to 36,000 m³/h, you will always find a solution to suit your needs

Countless combinations – always a solution

The many modules and their functions

Unique design with

Whatever your project, VEX4000 can take on the task, and with our EXselectPRO design program you can combine and put together your ventilation system as you wish. At the same time, the program provides you with detailed technical data, dimensional sketches as well as energy calculations and labels. It’s that easy!

Installation has never been easymore

Once you have configured your VEX4000 unit, you can choose to have it delivered in three different ways.

Heat pump in combination with ventilation

Requirements for energy efficiency and low energy consumption for ventilation solutions have given greater focus on combining heat recovery with an integrated heat pump. By combining ventilation, heating and cooling in one unit, a solution is achieved that is both very energy-efficient and much simpler than traditional cooling solutions with cooling machine and ducting on the roof.

With VEX4000RHP you get...

Heating, cooling and ventilation in one integrated unit
Factory tested unit
Advanced EXcon control system
No need for additional heating/cooling installations
Quick, simple calculation, documentation and technical data via EXselectPRO
One supplier for the complete solution

With a VEX4000RHP-ER, a rotating heat exchanger is placed between the evaporator and condenser, which gives the lowest energy consumption and the possibility of cooling recovery. With VEX4000RHP, the heat exchanger and heat pump are placed in separate modules, which contributes to a compact solution that is easier to transport.

Here we assume that the heat pump/heating coil must run half of the year at 33.3% capacity in order to achieve the supply air temperature. Compared to an electric heating coil, VEX4000 RHP and VEX4000 ER-RHP reduce heat consumption by 60% and 82% respectively.

Any extra investment when purchasing a heat pump will therefore pay for itself relatively quickly. Comparison with district heating, gas, oil or other energy source will depend on price per kW.

EXHAUSTO ALC ^TM*

The patented solution to prevent the spread of disease through a ventilation unit with rotary exchanger

ALC™ is a simple plug & play solution offered for VEX4000 with rotary exchanger. The solution prevents leakage and thus prevents the spread of viruses, particles and gases via the ventilation system. With activation of ALC^TM leakage is prevented by the VEX’s control system, regardless of the current operating situation.

How ALC works™

A sensor measures the pressure difference between the extract air and supply air chambers in the VEX unit.
The control system in the unit regulates an extract air damper based on the pressure difference.
This ensures that there is always lower pressure in the extract air chamber than in the supply air.

With the automatic leakage control, the Exhaust Air Transfer Ratio (EATR) is reduced to 0%** and recirculation of airborne particles and gases, including viral particles, is eliminated. At the same time, ALC™ is an energy-efficient solution, as demand-controlled operation can take place without leakage problems.

Advantages include:

A simple plug & play solution that can also be retrofitted
Exhaust air transfer rate EATR = 0%**
The perfect solution for hotels, educational institutions, offices, hospitals, shopping centres etc.

**Tested and validated at Danish Technical University. EATR = 0% based on Eurovent “Air Leakages in Air Handling Units: Guidelines for Improving Indoor Air Quality and Correcting Performance”, 2021, EN308 and EN16798-3

ALC – Automatic Leakage Control

EXcon control system

The VEX4000 unit is supplied with EXcon control system, which makes it possible to use EXHAUSTO’s patented adaptive pressure control (aDCV). Adaptive pressure control continuously optimizes the pressure in the unit depending on the building’s demand, which reduces energy consumption compared to traditional methods of pressure control (CAV, VAV, and DCV). Thanks to the patented adaptive pressure control, up to 43%* savings on energy costs can be achieved.

*Up to 43% compared to a unit with constant pressure control (VAV). Up to 20% compared to a demand-controlled system with constant pressure control (DCV)

Operate the system whenever and wherever you want

Settings and control are made with a web server from a PC, smartphone or tablet. Network communication supports BacNet over TCP/IP and Modbus over RS485 or TCP/IP. Communication with LonWorks can also be supported as an option.

Certified performance

VEX4000 – a result of experience and know-how

Although VEX4000 is a future-proof series, its development is based on our knowledge and know-how of quality products, which the market has known and appreciated for decades.

In the more than 60 years that EXHAUSTO has developed and produced ventilation solutions, the focus has always been on the ever-stricter requirements from legislation and customers.

We have combined our know-how from the VEX100-200-300 series with the knowledge we have gained from the unit series we have since purchased – and developed the VEX4000 series, which with a capacity range from 1,050 to 36,000 m³/h and completely unique configuration options can solve virtually all ventilation tasks within comfort ventilation

Your ventilation expert and professional partner

At EXHAUSTO, we never compromise on quality, and as experts in the field of ventilation with many years of specialist experience, you are not only guaranteed the best ventilation solution, but also a competent partner.

EXHAUSTO develops and manufactures high-quality products and systems for comfort ventilation in all areas of application – from offices, shops, schools and institutions to industrial buildings, hotels and hospitals.
