Fan
Single inlet centrifugal fan with back draw blades, statically and dynamically balanced G6.3 according to DIN ISO 1940
Direct driven EC motor with thermal protection, efficiency class IE3 (Premium Efficiency)
Fan mounted on anti-vibration blocs
Plug fan with epoxy coating, brand Ziehl Abegg (GTDHR 9010 in galvanized steel, brand EBM Papst)
Direct driven EC current motor with electronic commutation (EC) with high efficiency, thermal protection and integrated speed control
The EC technology has brought together high efficient EC motors with low energetic consumption for the management, control and the supervision of the duty point (regulation from 10 to 100%)
Low noise level for a better acoustic comfort
Exchanger

Efficiency 90% at -10°C/90% inlet air - +20°C/50% on exhaust air (EN308)
Filter
Filters are placed directly in front of the components for optimal protection
Mounted on sliding rails with lip seals to ensure efficient air tightness
Basic GTDHRV type as one F7 - ISO 16890 ePM1 – 55% (inlet air) and one G4 - ISO 16890 Coarse 65%(exhaust air)filters, thickness 100 mm
F7 high efficiency filter: 10x higher filtration surface than a gravimetric filter and life span 2.5x longer
Filter class M5 - ePM 10 50% - ISO 16890
Versions
GTDHRV 90xx-PBC: unit equipped with an integrated post-heating watercoil
GTDHRV 90xx-PBE: unit equipped with an integrated electrical post-heater
Options
GTDHRV DIVA®EC*: Proportional modulating flow (between a set min. And max. Flow) of each fan based on a built-in CO2 measurement.
The CO2 content (number of ppm) is adjustable in the control.
GTDHRV LOBBY®EC*: Constant pressure ventilation for each fan f.e. when used together with VAV controllers
GTDHRV MAC2®EC*: Two adjustable constant airflows for each fan. (except for the GTDHR 9008)
GTDHRV QUATTRO®EC*: Proportional ventilation between two constant air duties (high and low speed) for each fan (except for the GTDHR 9008) with built-in CO2 sensor in the exhaust side of the unit
* this regulation will be integrated in the unit. It is not possible to add this regulation afterwards
