Suitable for detached houses and apartment buildings as well as offices and apartments.The Comfort domestic ventilation system CWL Excellent with heat recovery extracts stale air from the kitchen, bathroom and toilet areas. This air is routed across a cross countercurrent plate-type heat exchanger and is expelled to the outside.At the same time, fresh outside air is drawn into the system, cleaned by an air filter, heated by the cross countercurrent heat exchanger and routed into the appropriate rooms, such as the living room, bedrooms and children’s rooms.Function• Design software based on DIN 1946-6.• The exceptional level of user friendliness enables competent, reliable air volume calculation in next to no time.• In addition, the software provides a complete list of materials, a matching quotation, numerous supplementary information, and a full ventilation concept in accordance with DIN 1946-6.• Download from www.wolf-systemprofi.deDesign softwareBenefits of the Wolf Comfortdomestic ventilation system• Clean, pollen-free fresh air - airing with your windows closed, excluding street noise (not only for those suffering from allergies).• Removable cross countercurrent plate-type heat exchanger made from plastic; up to 95 % heat recovery from extracted stale air.• One fan each for ventilation and extract air, both variable speed; low energy consumption through DC fans.• Constant flow fans keep the air flow rate constant at the selected fan speed.

This reduces the adjustment time considerably.The flow rate is, elative to the recommendation of approx. 3.0 m/s:Flexible hose system round: single hose DN 63/52 approx. ± 20 m³/h single hose DN 75/63 approx. ± 30 m³/hFlat duct system Excellent: single duct routing 50 x 100mm up to 30 m³/h single duct routing 60 x 130mm up to 55m³/hRouting informationFlat duct systemFlexible hose system round Pipe system specially designed for ventilation systems for flexible routing across or in false ceilings.Twin layer construction (smooth interior, corrugated exterior) ensures:Excellent sound insulation through low flow resistance; high annular stability yet high level of flexibility; low weight; the flat duct system Excellent assures neutral smell and anti-bacterial performance (optional) due to environmentally-friendly material (PE) and the use of hygienically ideal virgin materials. Minimum dust deposits through anti-static internal skin (optinal) mark out both the flexible round hose system and the flat duct system Excellent. Hygienically perfect due to easy to clean special internal skin. Tested without measurable contaminant concentration in the air. Shorter installation times through easy processing without special tools; no waste through endless routing via click joints; direct routing on unfinished concrete, screed or in false ceilings; watertight and airtight to DIN EN 1610 through the use of seal rings at joints. With the flexible roundhose system, two diameters are available (male:75/female:63 mm or male:63/female:52 mm); the flat duct system Excellent is available in the 50 x 100 mm size.Various air distributors are available for supply and extract air distribution in the building.Supply and extract air valves are integrated into the hose system via the connectors.The ventilation air and extract air lines, air distributors and connectors for the ventilation air and extract air valves are predominantly routed and installed on/above the ceiling and under the screed. The ventilation air and extract air valves may be installed either in the ceiling or the wall.These components may also be routed and installed in false ceilings.18Flexible hose system roundAir distribution hosewith smooth internal skin, anti-static 63/52, roll 50m 75/63, roll 50mwith smooth internal skin 63/52, roll 50m 75/63, roll 50mClick joint for air distribution hoseanti-static and anti-bacterial 63/52 75/63Seal ring 63/52, bag of 10 pce 75/63, bag of 10 pcePipe cap for 75 mm 63 mmAir distributor, for supply and exhaust air sound attenuating material to DIN 1946-6DN125: 10 connectors 75/63 with 5 pipe caps for supply and exhaust air eachAir distributor, for supply or exhaust air sound attenuating material to DIN 1946-6DN125: 6 connectors 63/52 with 3 pipe caps for supply or exhaust air each 5 connectors 75/63 with 2 pipe caps for supply or exhaust air eachDN160: 12 connectors 63/52 with 6 pipe caps for supply or exhaust air each 10 connectors 75/63 with 5 pipe caps for supply or exhaust air eachDN180: 18 connectors 63/52 with 6 pipe caps for supply or exhaust air each 15 connectors 75/63 with 5 pipe caps for supply or exhaust air eachLConnector for valve DN 125, one pipe capand two pipe connectorsanti-static and anti-bacterial 63mm, L = 325mm 75mm, L = 325mmClick ring, for round tube in conjunction with connector for valve DN 63/75mm 63/52, (bag of 10 pce) 75/63, (bag of 10 pce)LConnector for floor grille, one pipe capand two pipe connectors 63mm, L = 350mm 75mm, L = 350mm19Flexible flat duct systemReducer 90° from DN75 round to flat duct 50x100 anti-static and anti-bacterialFlat ductwith smooth internal skin, anti-static and anti-bacterial 50x100, roll 50m 60x130, roll 20mwith smooth internal skin 50x100, roll 50m 60x130, roll 20mFastening clips for flat duct 50x100, bag of 10 pce 60x130, bag of 10 pceCap for flat duct, anti-static und anti-bacterial 50x100, bag of 10 pce 60x130, bag of 10 pceBend 90° CWL for flat duct anti-static and anti-bacterial 50x100, Vertical 50x100, Horizontal 60x130, Vertical 60x130, HorizontalClick joint for flat duct anti-static und anti-bacterial 50x100 60x130Seal ring for flat ductanti-static and anti-bacterial 50x100, bag of 10 pce 60x130, bag of 10 pcePipe cap for flat ductanti-static and anti-bacterial 50x100, bag of 10 pce 60x130, bag of 10 pceOrifice plate for flat ductanti-static and anti-bacterial 50x100, bag of 10 pce 60x130, bag of 10 pce20Flexible flat duct systemAir distributor, for supply and exhaust air sound attenuating material to DIN 1946-6DN125: 6 connectors 50x100 with 3 pipe caps for supply and exhaust air eachAir distributor, for supply or exhaust air sound attenuating material to DIN 1946-6DN125: 5 connectors 50x100 with 2 pipe caps for supply or exhaust air eachDN160: 10 connectors 50x100 with 5 pipe caps for supply or exhaust air each 4 connectors 60x130 with 2 pipe caps for supply or exhaust air eachDN180: 15 connectors 50x100 with 5 pipe caps for supply or exhaust air each 8 connectors 60x130 with 4 pipe caps for supply or exhaust air eachLConnector for valve DN 125, two duct connections and one pipe cap anti-static and anti-bacterialLength L = 240mm 50x100 - 90° 60x130 - 90°LConnector for floor grille DN125, one or two duct connections and one pipe cap anti-static and anti-bacterialLength L = 220mm 50x100 (two duct connections) 60x130 (one duct connection)L Connector for valve DN 125, one pipe cap and two tube connectors 180° anti-static and anti-bacterialLength L = 250mm 60x130 - 180°Floor grille, metalwhite or stainless steel21Supply / extract air valvesSupply air valve plastic DN 125Supply air valve metal DN 125Extract air valve plastic DN 125Extract air valve metal DN 125Extract air valve plastic DN 125Supply air valve inductive DN 125Kitchen extract air valve with filter G322Notes23Notes24Wolf GmbH, PO Box 1380, D-84048 Mainburg, Tel.: +49 87 51 / 74-0, Fax: +49 87 51 / 74-1600, Internet: www.wolf-heiztechnik.deThe comprehensive equipment range from system supplier Wolf offers the ideal solution for commercial and industrial build-ings, for new build and for modernisation projects alike.
