2 Rotovex SR IAQ is a series of efficient ventilation units de - signed for schools, shops and offices, etc. The units are complete with controls and are delivered ready for operation. They are compact in design, have very low energy consumption and have high-efficiency rotating heat exchangers. The compact design Rotovex units are very compact and will fit through door openings with a width of 800 mm. Rotovex units can easily be divided into two parts, each of which is 772 mm wide. It could not be easier! Rotovex units are delivered pre-programmed, tested and ready for installation. Connect...

3 When the unit is delviered with constant duct pressure (VAV) two DSG 500 pressure sensors are enclosed. The unit is pre-programmed to regulate the temperature through cascade connected extract regulation. General Rotovex units are delivered enclosed in plastic and mounted on pallets. The units are fully connected internally. The automatic control system is preset and has been test-run at the factory. Cables for external components (supply, extract and outdoor air temperature sensors, outdoor air and exhaust air dampers, cooling, etc) are attached to a connection block on the end of the unit....

4 situation, the unit will re-start when the alarm has been ack nowledged and the overheat protection has returned to its normal state. If the man - ual protection is triggered, the electric heating coil must be removed for inspection and resetting. The heating coils are available in: Rotovex SR07 IAQ: 3 alt. 12 kW. Rotovex SR09 IAQ: 4,5 alt. 15 kW. Rotovex SR11 IAQ: 6, 12 or 24 kW. Electric heater (above 6 KW) has separate incoming power supply. The power demand of the electric heating coil is controlled by a triac power regulator (Pulser) according to the desired supply air temperature, which...

5 The units have an outgoing common alarm signal available at terminals (24 V AC, 0.5 A). Control on demand Rotovex have the possibility to control the airflow on demand to carbon dioxide (CO2). The CO2-sensor is easily connected to connection block. The output signal from the sensor can either be an analogue (0…10V DC) or a digital (1/10) signal. When using an analogue signal the airflow is controlled linear between two CO2 (ppm) setpoints. When using a digital signal the unit switch from reduced to normal airflow at the CO2 (ppm) setpoint. The CO2-sensors are accessories. Communication Rotovex...

7 Accessories EFD – Damper for outdoor/exhaust air Shutter damper EFD is a shut-off damper. The damper is provided with 24 V motors with spring-return actuators. EFD is manufactured to leakage performance class 3 according to EN 1751:1998 Annex C.2. Outdoor/exhaust air damper has the function to prevent the hot water battery to from freezing and also prevent the cold air from cooling down the building if the unit stops. Design The EFD multi-leaf damper comprises a number of opposed blades, swivelling on nylon bearings in a sheet metal framework. The blades are connected via a system of linkages...
