VEX4000, introduction
EXHAUSTO VEX4000 is a range of units suitable for many ventilation forms. The various section types can be combined and configured for practically any need. The units in the VEX4000 series cover a capacity range from 1050 to 36,000 m3/h.
World-class energy efficiency
With VEX4000 you can satisfy the international 2020 energy requirements by means of EC motor technology and a high condensation efficiency level exceeding 90 %.
EXHAUSTO's patented adaptive pressure control, which constantly optimises the pressure in the unit to match what the building requires, makes it possible to reduce your energy consumption even further than the traditional pressure regulation methods on the market (CAV, VAV and DVC).
Compact flexibility
All sections are mutually compatible in each model size, allowing the complete unit to preserve the same overall width and height. The units are available in LEFT and RIGHT versions.
EXHAUSTO offers three delivery options:
- The units are supplied ready-assembled and Exhausto ensures that all modules are correctly connected and assembled on a base frame.
- The modules are delivered separately, an advantage if they have to be transported inside the building. For this reason,VEX4000 has been specially designed for ease of assembly.
- The unit is delivered as a SPLIT version, where the unit is delivered unassembled as a flat pack. This means that even large units can be transported through small doors and then assembled on site. The SPLIT solution is more expensive, since specially trained EXHAUSTO technicians are required.
EXcon control system
All VEX4000 units are available with integrated control systems for advanced control of airflow, heating, cooling, humidification, etc. However, it is also possible to order VEX4000 without a control system. Read more about the EXcon control system under "EXcon control system for VEX4000".
EXselectPRO
VEX4000 is calculated and configured using the Eurovent and RLT-certified program EXselectPRO.
The program is used for configuration and energy calculations according to project requirements. The output consists of detailed technical data, dimensional sketches and energy calculations and the associated labels.
Designed for hygiene
VEX4000 is designed for hygiene in order to prevent pathogenic microorganisms or harmful chemicals from being released into the air. This means that:
- The unit is designed for easy inspection and cleaning.
- Materials and components used in the VEX4000 are hygienic and certified in accordance with VDI 6022-1.
