TECHNICAL DATA
VENTILATION UNIT WITH HEAT RECOVERY FOR COMMERCIAL AND INDUSTRIAL BUILDINGS
indoor air quality and energy saving
HRE-TOP ECNon-residential ventilator unit with dual flow and high yield heat recovery.
PERFORMANCEEquipped with counter current heat exchanger in alumi-nium (Eurovent certified) and electronic backward blade ventilators. The total bypass as standard allows favourable climatic conditions to be taken advantage of outside the building for free cooling (or free heating) in automatic mode.
STRUCTURE HRE-TOP EC is manufactured using a profiled extruded aluminium frame and 36 mm thick sandwich panels, insulated in polyurethane foam. The panels and inner parts are manufactured in Aluzinc , material that ensures high strength against corrosion and oxidation. A pair of panels with hinged opening eases access to the filters (F7 for the renewed air flow and M5 for the extraction air flow). HRE-TOP EC is prepared for installation outdoors (with an optional, specific protective roof) and indoors; it is supplied with 100 mm high aluminium bases for installa-tion on the floor. Available in 4 sizes, it can be equipped with air post-treatment systems (inside the unit) such as: hot/cold water battery, electrical heater or direct expansion battery.
CONTROLSHRE-TOP EC was supplied with an electric box and control system; it is available in a version equipped with EVO-PH control and a version equipped with EVOD-PH-IP control prepared for complete integration in home auto-mation systems (Modbus protocol with Ethernet connection or, on request, with the addition of connection RS485). The new version of our control systems enables extremely easy and rapid passage from a control system to another, even after installation with the single replacement of the remote panel.
The EVO-PH control has a coloured, backlit touch screen interface with intuitive viewing of the working status of the machine. It enables precise adjustment of ventilator speed and has a weekly , time schedule for automatic management of the ventilators. It can be controlled by an external switch to activate the booster function, it can automatically adjust the air flow rate if connected to an air quality probe, it can manage any air post treat-ment accessories, it automatically manages the bypass and prevents heat exchanger freezing by managing the speed of the ventilators or, if installed, an electrical pre-heating resistor (optional accessory outside the machine); it signals to the user the need to replace the filters (the clogging status of the filters is monitored by a pair of different pressure switches, supplied as standard) or an anomaly, indicating the origin. With the addition of optional accessories (COP kit and CAV kit installed on the channel) you can manage the ventilation machine in constant pressure or constant flow rate mode.
The EVOD-PH-IP control has the same characteristics as the EVO-PH version with the addition of Modbus commu-nication protocol which allows full control of the machi-ne by the supervision software of the home automation system. The implemented webserver allows interaction with the machine, even with an internet browser of a device connected (even from remote) to the home automation system in which the machine is inserted.
ACCESSORIESHRE-TOP EC can be equipped with other accessories such as:. R.H. of probe, CO2 or CO2 / VOC. Operating kit pressure or constant flow. protection roof for outside instalalzione. grilles and damper
