2| DVU and DVU-CDVU Cooling UnitAHU N o 07.02.339DANVENT DV10-240, TIME 10-40DVU is an air cooling system for TIME ec and DV air handling units. It is completed and tested from factory. It has a speedadjustable compressor; this makes it possible to adjust the cooling capacity exactly, which gives excellent comfort.Frequency converter and control are integrated.+Unit size TIME ec/DV-10 TIME ec/DV-15 TIME ec/DV-20 TIME ec/DV-25 TIME ec/DV-30 TIME ec/DV-40Recommended air flow m 3 /s 0,6 0,8 1,3 1,8 1,9 2,7Cooling capacity kW 11 15 23 32 35 49EER total at max cooling capacity 2,7 2,5 2,9 2,8 2,9 2,9Outdoor conditions: 32 °C/40% RH, extract air 25 °C/50% RH and supply air temperature 18 °C.DVU cooling unit• 6 sizes 2.150-9.700 m 3 /h,0,6-2,7 m 3 /s• Stepless control of cooling capacity• Cooling capacity and energy consumptionoptimized during operation• Separate control– independent simple and flexible• Fully mounted from factory• Cooling capacity up to 49 kW

DVU and DVU-C |3DVU-C Cooling UnitAHU N o 07.02.339DANVENT DV10-240, TIME 10-40The DVU-C is a unit with a rotary heat exchanger joined together with a stepless regulated air cooling system. The joining of thetwo gives the advantage of free cooling when the extract air temperature is below the outdoor air temperature. Consequently, asubstantial part of the cooling capacity is gained almost for free, and therefore a considerably smaller cooling unit may be required.+Unit size DV-10 DV-15 DV-20 DV-25 DV-30 DV-40Recommended air flow m 3 /s 0,8 1,2 1,6 2,0 2,5 3,2Cooling capacity kW 18 27 37 48 58 76EER total at max cooling capacity 4,6 4,4 4,7 4,4 4,9 4,5Outdoor conditions: 32 °C/40% RH, extract air 25 °C/50% RH and supply air temperature 18 °C.DVU-C cooling unit with cooling recovery• 6 sizes from 2.900-11.500 m 3 /h, 0,8-3,2 m 3 /s• “Free cooling capacity”• Stepless control of cooling capacity• Cooling capacity and energy consumptionoptimized during operation• Separate control – independent simple and flexible• Fully mounted from factory• Cooling up to 76 kW• Short length
