EVHRP SMALL High efficiency heat recovery unit for flow rates up to 320 m³/h
Description
Ventilation unit complete with heat recovery unit dedicated to air exchange without energy waste. The unit is particularly suitable for individual family units, flats and in all cases where the nominal air exchange rates do not exceed 320 m³/h. Constant flow rate selectable in 3 levels.
Characteristics
Sheet metal self-supporting frame. Galvanised sheet metal panels, painted on the outside, with high density EPS internal insulation; Alucobond Composite front panel.
High efficiency counter-current cross-flow polypropylene heat exchanger. Low freezing temperatures. Very high heat exchange efficiency.
Brushless fans with electronic motor and constant flow control; very high efficiency and low noise levels.
ePM1 70/80% filters with low pressure drop for both supply and exhaust, easily removable.
Use
Houses and surgeries for air exchange with up to 90% reduction in energy waste.
Control electronics for version S
The unit is supplied without electronic board and the fan speed is changed by means of a 0-10V input signal. It is possible to purchase the EVTDV remote terminal with LCD display separately, to control the speed of the fans and the bypass with various advanced functions, including:
- control of the speed of the individual fans independently, which means that the machine can be used in positive pressure or negative pressure mode;
- timed dirty filter warning;
- possibility of connecting the EVSQV air quality sensor, sold separately.
Control electronics for version IN2
Electronic board for 3-step speed management, antifreeze function and automatic bypass. Wall-mounted remote touch panel on 503 box. On-board temperature sensors and possibility of managing auxiliary hot water coil. Humidity / air quality regulators built into the remote display.
EVCNV2-N: advanced remote control with built-in humidity and VOC/CO₂ sensors, black.
EVCNV2-B: advanced remote control with built-in humidity and VOC/CO₂ sensors, white.
EVCNW2-N: advanced remote control with built-in humidity and VOC/CO₂ sensors and built-in Wi-Fi, black.
EVCNW2-B: advanced remote control with built-in humidity and VOC/CO₂ sensors and built-in Wi-Fi, white.
Electronic configuration IN2
A or B configurations selectable by electronics.
Notes
For vertical installation with configuration “A” a unit with an enthalpy heat exchanger must be requested. Quotation available upon request.

Horizontal Installation
Vertical Installation
For vertical installation with configuration “A”, a unit with an enthalpy heat exchanger must be requested.
In the case of vertical installation, it is possible to purchase the Aestethic Cover in composite panel in aluminum painted RAL9003.
Recessed Vertical Installation (only EVHRP SMALL 10-15)
The EVHRP SMALL units can also be installed recessed with the aid of a special formwork with 30 mm EPS insulation on all walls and 20 mm Foam insulation on the front closing panel, studied and designed in detail.
Two distribution boxes are housed in the formwork which allow the connection of up to 6 corrugated delivery pipes and 6 corrugated return pipes. The connection is made by means of sleeves with shutter suitable for the connection of the HTPE PLUS corrugated pipe with an internal diameter of 63 mm and an external 75 mm (on request a 76 mm internal and 90 mm external diameter). The sleeves for connecting the pipe are already included in the delivery of the formwork.
It is also possible to purchase the EXTERNAL INTAKE KIT necessary to create the external air intake and exhaust air expulsion directly above the formwork without the aid of further ducts.
N.B. For vertical installation with configuration “A”, a unit with an enthalpy heat exchanger must be requested.
