Ventilation unit with heat recovery SMARTY 2X PE PH – ceiling-mounted, enthalpic heat exchanger, preheating 1 kW, DN 125/160, 219 m³/h – SPECIAL OFFER

Product detailed description

What it is used for

SMARTY 2X PE PH (code IVU200PEPH) is a central ventilation unit with heat recovery for apartments, family and passive houses. It extracts stale air and excess moisture and replaces it with fresh outdoor 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, it offers many installation options. The version SMARTY 2X PE PH has an enthalpic heat exchanger, which transfers not only heat but also part of the moisture to the incoming air; the version with a standard heat exchanger has the code IVU200PPH.

Construction and equipment

• enthalpic counterflow heat exchanger, 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 servomotor 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 outdoor air, it is possible to use ePM1 70 % (F7) filter
• 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
• built-in electric preheater 1 kW

Control and accessories

The integrated control board miniMCB measures the temperature of the outdoor, 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 anti-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, must be ordered separately. As an addition, electric reheater IVAR.EKA NI (1.2 kW) is offered, which requires control GRGT034.

Installation

The dimensions of the unit (length × width × height) are 1100 × 590 × 250 mm. It is powered from a single-phase network 230 V / 50 Hz, total power / consumption is 1.16 kW / 5.4 A. The unit operates inside the building at ambient temperature 5 to 40 °C and ambient humidity up to 70 %; without anti-frost protection it can process outdoor air from -23 °C. Anti-frost protection works with flow imbalance and can create negative pressure in the house – for devices 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 outlet pipe G3/8. Controller (IVAR.TCP, IVAR.ST-SA, IVAR.SA-WIFI, IVAR.STOUCH or interface IVAR.MB-GATEWAY) and ductwork must be ordered separately.

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

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

What is the purpose of the integrated preheater 1 kW?
It preheats the outdoor air, so SMARTY 2X PE PH operates without anti-frost protection already from -23 °C (version without preheater from -8 °C). Therefore, a separate preheater into the duct is not added, only reheater IVAR.EKA NI can be added.
