Air conditioning air handling unit DFU

DFU is a plug & play ventilation unit with heat recovery Range is able to provide airflow from 500 to 3200 m3/h 6 sizes. Designed for spaces where fresh air exchange is required by regulations or simply to improve livability, DFU allows the recovery of up to 95% of the heat present in the expelled air. Features Ventilation unit with heat recovery Plug & Play The units are characterized by closing panels made of a double sheet of galvanized steel, pre-painted on the outer surface, completely removable for inspection/maintenance, and with different inlet/outlet configurations Mineral wool insulation and thermal break profile Internal heat and sound insulation made from mineral wool with a thickness of 30 mm Ventilation sections with EC plug-fan with 0-10 V C/C control with aluminum impellers with motor BLDC Upstream-flow heat recovery, with aluminum or pre-painted aluminum heat exchanger sealed at the ends in order to prevent contamination of the fresh air. Bypass damper inserted inside the unit controlled by the DFU control system F7 filter on the outlet (F9 optional) and M6 on the intake Condensate collection and drainage container constructed with AISI 304 stainless steel sheet. Designed for inclusion of post-heating exchanger inside the unit Controls Ventilation control: Constant speed as STD; Variable speed based on constant flow rate (accessory); Variable speed based on constant pressure (accessory); Variable speed based on CO2/VOC probe for IAQ control (accessory); Management of the by-pass damper; Check for filter clogging; Standard antifreeze function with flow unbalancing; Optional antifreeze function with flow unbalancing
