indoor air quality and energy saving TECHNICAL DATA HRE-TOP EC VENTILATION UNIT WITH HEAT RECOVERY FOR COMMERCIAL AND INDUSTRIAL BUILDINGS

HRE-TOP EC Non-residential ventilator unit ith dual flo and high yield heat recovery. PERFORMANCE Equipped ith counter current heat exchanger in aluminium (Eurovent certified) and electronic backard blade ventilators. The total bypass as standard allos 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 sandich 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 ith hinged opening eases access to the filters (epm1 7% (F7) for the reneed air flo and epm1 % (M) for the extraction air flo). HRE-TOP EC is prepared for installation outdoors (ith an optional, specific protective roof) and indoors; it is supplied ith 1 mm high aluminium bases for installation on the floor. Available in 4 sizes, it can be equipped ith air post-treatment systems (inside the unit) such as: hot/cold ater battery, electrical heater or direct expansion battery. CONTROLS HRE-TOP EC as supplied ith an electric box and control system; it is available in a version equipped ith EVO-PH control and a version equipped ith EVOD-PH-IP control prepared for complete integration in home automation systems (Modbus protocol ith Ethernet connection or, on request, ith the addition of connection RS48). The ne version of our control systems enables extremely easy and rapid passage from a control system to another, even after installation ith the single replacement of the remote panel. The EVO-PH control has a coloured, backlit touch screen interface ith intuitive vieing of the orking status of the machine. It enables precise adjustment of ventilator speed and has a eekly, time schedule for automatic management of the ventilators. It can be controlled by an external sitch to activate the booster function, it can automatically adjust the air flo rate if connected to an air quality probe, it can manage any air post treatment 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 sitches, 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 flo rate mode. The EVOD-PH-IP control has the same characteristics as the EVO-PH version ith the addition of Modbus communication protocol hich allos full control of the machine by the supervision softare of the home automation system. The implemented ebserver allos interaction ith the machine, even ith an internet broser of a device connected (even from remote) to the home automation system in hich the machine is inserted. ACCESSORIES HRE-TOP EC can be equipped ith other accessories such as:. R.H. of probe, CO or CO / VOC.
