RKE heat recovery units are suitable for residential and commercial applications and offer a real energy saving in for-ced ventilation plants, by using an aluminum plated crossﾚow heat exchanger, able to transfer more than 50% of heat which otherwise would be lost with air exhaust.

These units may be integrated with traditional heating and cooling systems (such as fan-coils, water heaters, etc.) and can operate both in summer and winter seasons.

RKE series consists of 10 models, with airﾚow rate from 200 m³/h to 6800 m³/h; all the units are particularly suitable for false ceiling installation and may be appropriately ducted allowing air supply and air suction directly in the room.

RKE units are available in the following base versions:

ｰ RKE horizontal unitｰ RKE/V vertical unit.

This digital controller is intended for temperature regulation in environments equipped with heat recovery unit or air conditioning unit. The device automatically controls the fan speed (manual or automatic 2/3 step fan speed control) as well as the possible valves/electric heater in order to adjust the room temperature in the most suitable way. Temperature acquisition can be performed either with the control panel internal sensor or with an external one (accessory NTC).

The control panel is suitable to manage two water coil for heating/cooling (4 pipes system), or single coil (2 pipes system) and/or electric heater; moreover it includes a manual or automatic heating/cooling changeover, an economy function to reduce power consumption (it allows to temporary set an energy saving mode through a reduction of the actual set point temperature by a step when in heating mode, or increasing it by the same step when in cooling mode), and clogged ﾙlter alarm by setting the time-to-maintenance.

This device can drive in a proportional way both valves and fan in order to control room temperature with the highest comfort and energy saving, following a proportional band for fan and proportional and integral for valves: the regulator will drive this valve through power pulses with one second resolution in a way that its stem will reach the position needed for the regulation, thus performing a modulation. The regulator, as soon as power is ﾙrst applied, and before it starts the actual regulation, will perform a stem position re-synchronization cycle, which is obtained by closing the valve for a time which is 150% of the value stored as nominal opening time. This cycle will be periodically repeated in order to recover possible positioning errors which might be accumulated during time.

Q Controls

Ź Speed control CVU

It is composed of a 2/3 step fan speed control (min/med/max air speed) and a manual off/cooling/heating switch, capable of connecting an antifreeze thermostat (accessory TEG) that can stop the unit in heating mode.

Temperature acquisition can be performed either with the control panel internal sensor or with an external one (accessory NTC).The control panel is suitable to manage two water coil for heating/cooling (4 pipes system), or single coil (2 pipes system) and/or electric heater; moreover it includes a manual or automatic heating/cooling changeover, an economy function to reduce power consumption (it allows to temporary set an energy saving mode through a reduction of the actual set point temperature by a step when in heating mode, or increasing it by the same step when in cooling mode), and clogged ﾙlter alarm by setting the time-to-maintenance.This device can drive in a proportional way both valves and fan in order to control room temperature with the highest comfort and energy saving, following a proportional band for fan and proportional and integral for valves: the regulator will drive this valve through power pulses with one second resolution in a way that its stem will reach the position needed for the regulation, thus performing a modulation. The regulator, as soon as power is ﾙrst applied, and before it starts the actual regulation, will perform a stem position re-synchronization cycle, which is obtained by closing the valve for a time which is 150% of the value stored as nominal opening time. This cycle will be periodically repeated in order to recover possible positioning errors which might be accumulated during time.

It consists of an on board electrical panel totally wired and a remote control panel that allows temperature regulation in environments equipped with heat recovery unit or air conditioning unit; it is an easy plug and play electronic control. The device automatical-ly controls the fan speed (manual or automatic 3 step fan speed control or continuous control, based on CO2 sensor AQS or pressure transducer DPS) as well as the possible valves/electric heater in order to adjust the room temperature in the most suitable way. Temperature acquisition can be performed either with the supply air sensor, as standard, or with the return air sensor.

This digital controller is intended for temperature regulation in environments equipped with heat recovery unit or air conditioning unit. The device automatically controls the fan speed (manual or automatic 2/3 step fan speed control) as well as the possible valves/electric heater in order to adjust the room temperature in the most suitable way. Temperature acquisition can be performed either with the control panel internal sensor or with an external one (accessory NTC).

The control panel is suitable to manage two water coil for heating/cooling (4 pipes system), or single coil (2 pipes system) and/or electric heater; moreover it includes a manual or automatic heating/cooling changeover, an economy function to reduce power consumption (it allows to temporary set an energy saving mode through a reduction of the actual set point temperature by a step when in heating mode, or increasing it by the same step when in cooling mode), and clogged ﾙlter alarm by setting the time-to-maintenance.

Q Controls


It is composed of a 3 step fan speed control (min/med/max) and a manual off/cooling/heating switch with capacity to connect an antifreeze thermostat (accessory TEG) that can stop the unit in heating mode.

This device can drive in a proportional way both valves and fan in order to control room temperature with the highest comfort and energy saving, following a proportional band for fan and proportional and integral for valves: the regulator will drive this valve through power pulses with one second resolution in a way that its stem will reach the position needed for the regulation, thus performing a modulation. The regulator, as soon as power is ﾙrst applied, and before it starts the actual regulation, will perform a stem position re-synchronization cycle, which is obtained by closing the valve for a time which is 150% of the value stored as nominal opening time. This cycle will be periodically repeated in order to recover possible positioning errors which might be accumulated during time.

LThe frame is made from extruded ALUMINUM proﾙles with a safety shape that eliminates dangerous internal protube-rances, due the screws used to joint the panels; so ﾙnally no screws are visible inside the unit.An EPDM gasket is installed on the proﾙle; it is formed with a rigid base for the frame ﾙxing and a soft surface to adapt to the panel and to guarantee the minimum leakage of the casing.

In this range, 4 different frames are used, according to size and the destination of the unit:A) ｰ 40 mm standard proﾙle, with 42 mm thickness panel == size from 14 to 215B) ｰ 60 mm standard proﾙle, with 62 mm thickness panel == size from 235 to 855C) ｰ 40 mm thermal break proﾙle, with 42 mm thickness panel == size from 14 to 215D) ｰ 60 mm thermal break proﾙle, with 62 mm thickness panel == size from 235 to 855

A B C D

The execution with thermal break proﾙle is particularly suitable in the cases in which a strong difference of temperature is present between inside and outside unit: very warm or very cold areas and/or installations with very strong cooling or heating treatment. Very suitable for tropical environments.

The panels are available in the following conﾙgurations:ｰ External side in prepainted steel RAL 9002 ｦ internal side in galvanized steelｰ External side in prepainted steel RAL 9002 ｦ internal side in ALUMINUMｰ External side in prepainted steel RAL 9002 ｦ internal side in stainless steel
