Ventilation unit with heat recovery SMARTY 2X PE – ceiling-mounted, enthalpic heat exchanger, DN 125/160, 219 m³/h – SPECIAL OFFER

Product detailed description

What it is used for

SMARTY 2X PE (code IVU200PE) is a central ventilation unit with heat recovery for apartments, family and passive houses. It removes stale air and excess moisture and replaces it with fresh outside air, which is preheated in the heat exchanger by the heat of the exhaust air – the house is ventilated without opening windows and with minimal heat loss.

The unit is mounted under the ceiling and thanks to its height of only 250 mm offers many installation options. The version SMARTY 2X PE has an enthalpic heat exchanger, which transfers heat and part of the moisture to the incoming air; the version with a standard heat exchanger has the code IVU200P.

Construction and equipment

• enthalpic counterflow heat exchanger with thermal efficiency of 75.7 % (data according to EU regulation 1254/2014), energy efficiency class A for average climate
• EC fans with variable speed control – power consumption at maximum flow 103 W, reference specific power index SPI 0.33 W/(m³/h), sound power level 49 dB(A)
• summer bypass with servo motor for 100 % bypass of the heat exchanger and night cooling
• Coarse 65 % (G4) filters on the supply and exhaust side, size 185 × 168 × 25 mm; for outside air it is possible to use filter ePM1 70 % (F7)
• enclosure made of galvanized steel with powder coating in white color RAL 9016 (corrosion resistance C3), thermal and acoustic insulation from EPP of thickness 20 mm, tightness class A1

Control and accessories

The integrated control board miniMCB measures the temperature of the outside, supplied and extracted air and controls the fans, bypass and external components (preheater, reheater, air regulators). It offers three manual modes, intensive ventilation (boost), time program, night cooling, mode for fireplaces and intelligent frost protection; it is possible to connect CO2 sensor (IVAR.CO2) or humidity sensor.

The controller is not part of the unit – wall controller (IVAR.TCP, IVAR.ST-SA, IVAR.SA-WIFI, IVAR.STOUCH) or interface IVAR.MB-GATEWAY, which allows control from PC and via application IVAR.SMARTYAIR on smartphone or tablet, is ordered separately. For preheating of outside air, electric preheater IVAR.EKA (1.2 kW) is available, for reheating of supplied air independent reheater IVAR.EKA NI (1.2 kW) with control GRGT034.

Installation

The dimensions of the unit (length × width × height) are 1010 × 590 × 250 mm, weight 40 kg. It is powered from a single-phase network 230 V / 50 Hz, total power / consumption is 0.16 kW / 1.05 A. The unit operates inside the building at ambient temperature 5 to 40 °C and ambient humidity up to 70 %; without frost protection it can process outside air from -8 °C. Frost protection works with flow imbalance and can create negative pressure in the house – for appliances that take air from the room (stove, boiler), the manufacturer recommends to turn it off and use preheater. It is not installed into living rooms without additional noise insulation and is not intended for pools or saunas. Installation, electrical connection and maintenance must be performed only by a qualified technician and the unit must be grounded.

Technical parameters

Frequently asked questions

What is included in the delivery and what needs to be ordered separately?
The unit is delivered with mounting accessories – four anti-vibration pads, cover plugs, key and output pipe G3/8. Controller (IVAR.TCP, IVAR.ST-SA, IVAR.SA-WIFI, IVAR.STOUCH or interface IVAR.MB-GATEWAY) and air ducting are ordered separately.

Where should the unit not be installed?
Only into living rooms with additional noise insulation and never into pools, saunas or similar spaces. The unit is intended for interior use with ambient temperature 5 to 40 °C and humidity up to 70 %.

How often are the filters changed?
The manufacturer recommends replacement every 3 to 4 months or sooner according to the warning on the controller. Filters Coarse 65 % (G4) with size 185 × 168 × 25 mm are used, for outside air also ePM1 70 % (F7); the unit must not be operated without filters.

Does the unit need preheating of outside air?
Without frost protection, SMARTY 2X PE operates at outside air from -8 °C. For colder periods, electric preheater IVAR.EKA (1.2 kW) is added to it; model 2X P is also produced with integrated preheater 1 kW (IVU200PPH, IVU200PEPH).
