Prekė: Vėdinimo įrenginys DEFRO DRX 400 V OPTI, 450 m³/h. Kategorija: Rekuperacinės vėdinimo sistemos.
- Gamintojas: Defro
- Modelis: REKU-DRX-OPTI-400-V
Defro DRX 400 OPTI V recuperator with a capacity of 450 m3/h
with electric preheater and automatic bypass
The most important features of the control panel:
- Housing made entirely of powder coated steel, sound-absorbing insulation gr. 30 mm is characterized by excellent vibration damping properties, noise.
- Heat exchanger the most effective and reliable cross-current polystyrene with high efficiency heat exchange - a reputable Core company with many years of experience.
- Fans - electro commutator motors direct current EC EBM Papst were used to guarantee reliability and energy-saving quiet operation.
- Automatic bypass – the control panel is equipped with 100% by-pass, providing, if necessary, the possibility of cooling the room thanks to the direct supply of cool air to the rooms from the outside in the summer without the need to replace the exchanger with summer cassettes, which in retrospect and operation is quite burdensome in operation.
- High-end ISO filtering Coarse ≤ 50 %
- Preheater with modulated power, starts automatically, prevents the exchanger from freezing.
- Modern touch controller – advanced automation allows you to precisely adjust the parameters of the control panel for the current installation and prevailing weather conditions.
- Reversible unit, so that the arrangement of the stubs will always match the installation.
Basic functions of control panel automation:
- GWC control
- control of the pre-/secondary heater
- bypass control
- setting a weekly schedule
- filter contamination indicator
- control of the heating system
- reading of all temperatures
- Humidity sensor (optional)
- co2 sensor (optional)
- On-line control (optional)
Defro DRX is a series of economical and compact control panels
PLUG&PLAY ventilation, which are the main
element of mechanical ventilation system.
Their main task is to replace and process air.
Defro control panels are high-class supply and exhaust devices
with heat recovery, which is carried out by means of
high-efficiency cross-current exchangers.
CONTROL – touch control panel
- colour intuitive display 4,3”
- matching the optimal expenditure for the building
- protection of the exchanger against freezing .
- AFC system – ANTI FREEZE CONTROL cooperating with modulated preheater
- weekly programme
- function - hearth, holiday, party, hood
- control of peripheral devices
- manual and automatic control 100 % - by-pass
- possibility to extend by wireless control with ST-505 Internet communication module (LAN) or WiFi RS Internet communication module for mobile communication e-Module
