The Vents VUE2 250 PU EC unit is equipped withtwo recuperators made of polymerized paper.
Suspended supply and exhaust units are a completely finished ventilation device that provides fresh air supply, filtration and removal of polluted air from the room. This series has very low consumption - only 135 W with a fairly high productivity of up to 275 m3/h. At the same time, this model ensures the transfer of moisture from the exhaust air to the supply air in two plate recuperators.
Installation must be carried out indoors, are round air ducts of nominal diameterconnected to the unit? 125 mm
House
The unit body is made of painted steel. Thermal and sound insulation is made of foamed polypropylene 20 mm thick.
Filter
To filter the supply and exhaust air, the unit uses two pocket filters with a cleaning degree of G4.
Fans
Highly efficient electronically commutated (EC) external rotor motors are used, equipped with impellers with backward-curved blades. Such motors are by far the most advanced solution in the field of energy saving. EC motors are characterized by high performance and optimal control over the entire speed range. The undoubted advantage of electronically commutated motors is their high efficiency (up to 90%).
Recuperators
Recuperators made of polymerized paper transfer sensible and latent heat. They are frost-resistant and do not produce condensation. Installations with this type of recuperator are recommended for use in rooms equipped with air conditioning.
The VUE2 250 PU EC installation uses two cross-current recuperators made of polymerized paper.
Installation design
Control and automation
The unit is equipped with a built-in automation system and a multifunctional control panel (P3/010 T) with LED indication. Also included in the package is a signal cable to connect the unit to the control panel. To prevent the recuperator from freezing during the cold season, the unit is equipped with an active protection system. The temperature sensor stops the supply fan, while the warm exhaust air warms up the recuperators. The supply fan then turns on and the unit continues to operate as normal.
The control panel performs the following functions:
- Turning the unit on/off,
- Selecting the ventilation mode: min., medium, max.
- Setting the minimum mode in a range of 7 preset levels. In this case, the average mode is automatically set to 80 m3/h above the minimum, but not higher than the maximum.
- Indication of the need to replace the filter.
Installation
The unit is designed for suspended ceiling installation and can be installed on a balcony, pantry, basement, attic and other auxiliary rooms. The unit can also be installed in main rooms directly to the ceiling, behind a suspended ceiling or installed in a ceiling niche. Access for service from the bottom panel.
