air-handling unit RLI-RLE
Construction
The housing of the RLI / RLE control panels is made entirely of a double layer of steel sheet 2×1 mm thick, galvanically zinc plated, in a frameless technology – this eliminates the phenomenon of the so-called cold bridges. Thermal and acoustic insulation with mineral wool with a thickness of 40 mm and a density of 88 kg / m3
In the RLI / RLE units there is a throttle valve with a spring return actuator installed. As a standard, the units are equipped with EU5 class panel filters at the inlet air inlet and EU7 at the inlet air inlet. In order to control the state of contamination of the filters, pressure controls have been used, which are included in the automation equipment of the control panel. Exceeding the admissible values will display a message informing you that filters must be changed.
Heat recovery is carried out using a rotary exchanger.
Fans
In the RLI / RLE type control panels, energy-saving JETTEC fans with motors adapted to be adjusted by inverters and JETTEC EC electronically commutated. The diagonal design of the rotor ensures the highest efficiency parameters in this class of fans.
In RLE type units, JETTEC fans are supplied as separate components for installation in the duct.
Drive and control
All models of RLI / RLE are powered by three-phase 400V, 50Hz. Equipped with a complete automation to control the operation of the control panels (including multilevel dampers, anti-freeze protection, EC regulators, service switch)
Rotary exchanger
The efficiency of heat recovery in RLI / RLE units is up to 82%. The rotary exchanger used in them is made of wavy aluminum sheet wound on a cylinder. The rotary movement of the exchanger provides a belt-driven motor. The heat exchange plane resulting from rotational motion is much higher than in the case of standard cross-flow exchangers.
The panels can be mounted on the roof using a roof cover (optional).
