SupraBox DELUXE
Energy Recovery Units
SupraBox DELUXE energy recovery units are ideal for use in classrooms and seminar rooms, as well as in offices and recreation rooms. Thanks to the integrated supply air outlet and direct extraction of exhaust air via the unit, no additional ventilation pipes are required in the room. A CO2-based control system ensures maximum comfort and creates optimum indoor air quality. Depending on the occupancy of the room and the number of people, two units with different air flow rates are available. Both units generate a maximum sound pressure level of 35 dB(A) (at a distance of 1 m in the room), ensuring undisturbed use of the room.
Advantages:
- Ventilation is regulated according to demand.
- No noise pollution from the environment.
- Heat from the exhaust air is transferred to the fresh outside air (heat recovery).
- With good heat recovery, no additional heating is required for ventilation.
- No heating costs for ventilation.
- Room ventilation is also possible when you are away and at night. (safety)
- Free night cooling of rooms with cool outside air
- No temperature fluctuations when it’s cold outside due to window ventilation
- Limit values of 1,000 ppm are maintained at all times
Easy installation in the room
The units can be positioned flexibly in the room and stand securely on the floor. Thanks to the direct extraction of exhaust air from the room via the unit and the integrated source air outlet, no additional room ventilation pipes or sound and fire protection measures are required. The units can also be supplied as fully or partially integrated versions specifically for rear wall mounting.
Maximum energy efficiency
Highly efficient heat recovery and energy-saving Rosenberg fans with state-of-the-art EC technology make these units energy-saving ventilation systems at the cutting edge of technology. A sophisticated integrated defrosting concept eliminates the need for a preheating or reheating coil.
Integrated bypass
The units have an integrated, 100% controllable bypass, which can be used to achieve controlled free cooling during active ventilation (e.g. cooler outside temperatures in the early hours of the morning in summer) and free night cooling of the rooms.
Ventilation concept:
Displacement ventilation
The SupraBox DELUXE works on the principle of low-turbulence displacement ventilation. This involves introducing fresh air into the room at low speed, where it forms a pool of fresh air. The air rises from heat sources, such as people, and flows through the room from bottom to top. The exit velocity at the displacement ventilation outlet is virtually immeasurable, which ensures draught-free ventilation.
With displacement ventilation, the air quality in the occupied area is up to twice as good as with turbulent mixed ventilation (VDI 3804)!
Integrated and
demand-based control
The energy recovery units include a fully wired internal control system. The units operate continuously in automatic mode, 100% demand-based, and ensure that the maximum desired CO2 concentration in the room is maintained. The supply of outside air is controlled by a CO2 sensor installed in the room. If there are no longer any people (CO2 producers) in the room, the units switch themselves off automatically, thus eliminating unnecessary energy consumption. In addition to automatic mode, the integrated time programme can be used to set different intervals for each day of the week. This means that the air quality in the room can be improved by varying the constant air flow rates, regardless of room occupancy.
