Sirocco - Product rangeLRK – Tunnel equipmentTRD – TUNNEL VENTILATION DAMPERSAre made of high-quality stainless steel (1.4571). They stand out through theirexcellent air tightness values and corrosion resistance and can be used intemperatures of up to 400°C.HID – INDUSTRIAL DAMPERSAre used for general industries. The dampers are standardized and used amodular design. Extensive Certificates (Fire 4h 1120°C, Operation 400°C)according to international demands.HDD – SEAL-OFF DAMPERSManufactured in heavy gauge mild steel, these welded dampers are installed infan systems as separation and shut off dampers. They are suitable for operatingtemperatures of up to 600°C..

Sirocco - Product rangeLRK – Tunnel equipmentWSG – WEATHER GRIDTo protect the fans from snow and dirt, stainless steel wire meshes are used infresh air inlet canals.LKE – AIR DUCT FIXTURESDiversion vanes are implemented to minimize the flow-loss in duct delays anddiversions. The radius of the curvature, as well as the number and spacing of thediversion vanes are adjusted to suit the profile in order to guarantee optimal flowthroughconditions.MAD – MOUNTING COVERSIn order to close the openings through which the ventilation systems are broughtinto the designated spaces, movable mounting covers are used. These coversare soundproof and temperature insulated and are manufactured from variousmaterials according to customer requirements..

Welded and bolted construction with stainless steel blades and wingflapside seals to ensure the requirements of the ship to keep updated. Its rigidform of the leaf is a through-penetrating avoided by flames..

Sirocco - Product rangeIndustrial fansThe SIROCCO range of industrial fans includes both radial and axial types. Impellerdiameters are up to 3 meters (1.000.000m³/h with pressure up to 25 kPa and operatingtemperatures up to 650°C). Application areas: power stations, paper mills, cement andchemical production industries.RADIAL FANSThe volume range reaches 1.000.000 m³/h at a steadily rising pressure of up to25 kPa. They guarantee a high degree of efficiency, a rugged design andpermanent economic operation.AXIAL FANSConsist of a rugged, welded housing in which a dynamically balanced impeller(cast aluminum, synthetic material or welded steel construction) is built-in..

Sirocco - Product rangeHeat exchangersFINNED TUBES HEAT EXCHANGERAir-water heat exchangers for the cooling or the heating of generators, motorsand air handling in power and industrial plants. Tube materials: copper, coppernickelalloy or stainless steel. Cooling fin materials: aluminum, copper or stainlesssteel. The connection between tubes and fins is established through highpressure enlargement.BARE-TUBE HEAT EXCHANGERBare-tube heat exchangers are predominantly used for the cooling of generationoil, engine bracket oil and gearing oil. Tube materials: steel, brass, copper-nickelalloysor stainless steel.PLATE HEAT EXCHANGERPlate heat exchangers are constructed according to the counter flow principle,consisting of a screwed or a hard-soldered stainless steel plate package and aremainly used for cooling respectively heating water and oil..

Sirocco - Product rangeHeat exchangersAIR PATH CASINGAir path casings are used for air duct and are suitable for mounting air-water heatexchangers. Own construction or custom-built made of steel sheets, canted,welded and coated.COOLING UNITCooling units are used to cool the air of generators and motors, consisting of airwaterheat exchangers, air path casing, built-in fans as well as filters andmonitoring equipment if needed.RAILED VEHICLES (train and underground)Complete units for the cooling of traction motors and power converters of railedvehicles, consisting of water-air coolers, fans, expansion tanks, pumps,monitoring equipment, incl. pipe work and wiring..

Sirocco - Product rangeAir technology for paper and pulp industryEXTRACTOR HOODSExtractor hoods for paper machines are dimensioned for a dew point up to 65°C.Construction: double-walled made of aluminum, isolation with mineral wood. Withautomatic lift doors on the operation side.HEAT RECOVERY PLANTSIn most modern construction, compact assembling with low pressure lossesstandard is a 3-step construction:1. step: air / air heat exchanger for heating of the drying air2. step: air / water heat exchanger for production of warm water for the heating ofthe building for the machinery (ventilation air)3. step: for heating of the process waterINCOMING AND EXHAUST AIR PLANTSSeveral kinds of Incoming and exhaust air plants for aeration of the machineshops, wet air suction, aeration of the drying section, aeration and ventilation ofthe sub plant like electric plants and control gear rooms, pulper suction.

Sirocco - Product rangeAir technology for paper and pulp industryWET AIR EXTRACTION SYSTEMDuring the paper production, great quantities of fog and saturated wet air isformed, due to the moved water masses in the wire section of formers. For thispurpose, we apply special eliminators that separate the steam (as condensate)from the air and return the water to the production process.PULPER EXTRACTION SYSTEMTo avoid bothersome humid air emission from the pulper in the wet section (aswell as pulpers in the dry section, the yankee, winder and slitter winder section),the air emission is extracted by radial fans before ist can leave the pulper. Thedimensioning of the duct system, the radial fans and the auxiliary equipment isdependent on pressure conditions & pulper design (either closed or open design).PAPER EDGE TRIM REMOVAL SYSTEMPaper edge trim removal with synchronization to winders for optimal adjustmentof suction output at any cutting speed (by adjusting position of bypass deflector).We also paper waste management plants as a whole, with radial shredding fanscyclone separators, conveyor systems, piping for edge trim and paper waste aswell as control systems..
