Important! Copper-aluminium plate heat exchanger is used as a water heat exchanger, water or non-freezing mixtures can be used as a heat carrier, maximum temperature of the heat carrier is 150°C, maximum pressure is 1,5MPa, dimensions of the heat exchanger are 400x200. There are holes for air and water drainage. To regulate the supply air temperature there is a thermoregulation unit. Purpose. In standard version AirK units are manufactured with galvanised steel casing. The compact heat-insulated casing (insulation thickness 30 mm) contains: filter (flat filter of G3 cleaning class is used as a filtering element), fan (fan casing is plastic, steel impeller), water or electric air heater. Capacity - up to 1000 m3/hour. Installation design. The unit is operable in any spatial orientation. To change the filter, the service panel is removed. As a rule, the service panel should be located at the bottom. The unit is quite easy to install: brackets are provided in the unit body for mounting to building structures. There is one inlet and one outlet Ø 200 for connection to the duct system. It is recommended to connect the unit with flexible noise-insulated ducts. To achieve optimum acoustic and aerodynamic performance, a straight ducting section of about 1m should be provided after the unit's exhaust. Standard functions. Remote control with LCD display, non-volatile real-time clock and multifunctional timer, monitoring of the main process parameters and detection of emergency situations. Control of the air handling unit is carried out according to the set programme, including: automatic regulation of the supply air temperature in accordance with the preset set point | smooth control of the coolant flow rate by means of the temperature control unit SUS with 0-10V electric actuator | control of the temperature sensors status | control of the fan motor | control of the filter contamination | operation according to the timer | control of the main technological parameters and detection of emergency situations | multistage protection of the heat exchanger against freezing. In the event of an emergency, the control unit will automatically switch off the unit and signalise the cause of the fault. The information on the alarms of the protections can be viewed on the control panel Z033. There is no automatic changeover between summer and winter time. The control unit is manufactured according to the requirements of TU 4862-002-45687431-2013.
