The Vents VUT2 250 PU EC unit is equipped with two aluminum heat exchangers.
The Vents VUT2 250 PU EC suspended supply and exhaust unit is a fully finished ventilation device that ensures the supply of fresh air air, filtering and removing contaminated air from the room with a nominal capacity of275 m3/h. The use of such an installation allows you to reduce ventilation costs, the maximum consumption is only 135 W.
The installations are used in ventilation and air conditioning systems for premises for various purposes. The units have a very low noise level due to the placement of fans between two heat exchangers. Designed to connect to round ducts of nominal diameter? 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
The installation uses two aluminum recuperators of cross-current, and it is also equipped with two trays for condensate drainage. Aluminum recuperators transfer sensible heat from the exhaust air flow to the supply air flow. They have a long service life in cold climates.
Installation design
Control and automation
The installation 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.
