2 air-handling units db Application Air-Handling Units DB are used for the off-shore and marine industry. The air handling units are specially designed to be compact and allow for fitting in the often limited space of ships, yachts and offshore modules. The fans are made of high-quality materials to withstand the extreme sea climate conditions. The Air-Handling Unit is made of the most sturdy materials to withstand extreme cold or hot and humid air conditions, the salt sea air and the extreme environments. Standards The units comply with the following guidelines: Machinery Directive 2006/42/ EC Low Voltage Directive 2006/95/EC ATEX 94/9 / EC (ATEX 95) EMC Directive 2004/108/EC Pressure Equipment 97/23/EC The units conform to the following casing-properties (according to EN 1886): Mech. Strength class: D1 Air leakage enclosure class: L1 Filter bypass leakage: F9 Therm. Conduction: T2 Thermal bridge factor: TB2 Certification ISO 9001 To offer complete operational security to those who ensure ours

Explosion proof If the units are located in hazardous locations such as in plants where an explosive atmosphere may occur (so-called zone I and II locations), they are built according to ATEX

Anything that might cause the tiniest spark is forbidden there.

3 Explosion proof If the units are located in hazardous locations such as in plants where an explosive atmosphere may occur (so-called zone I and II locations), they are built according to ATEX directives. Even plain air can be hazardous when it holds inflammable gases. Areas like that are called ATEX zones (ATmosphères EXplosibles). Anything that might cause the tiniest spark is forbidden there. Since July 1, 2003, every company in Europe, active in these zones, must meet the ATEX 137 guideline (guideline 1999/92/EG) for personal and ATEX 95 guideline (guideline 94/9/EG) for equipments used in ATEX zones. Air handling units must meet the ATEX regulations when handling Ex-atmosphere or positioned in Ex-atmosphere. Two types are distinguished: Zone I: explosion hazard under normal operation, and Zone II: explosion hazard not likely. Alternatives available on request. Due to continuous product development, Heinen & Hopman reserves the right to introduce alterations without prior notice.

Casing The casing is built out of a aluminium framework (optional: galvanized steel or welded stainless steel AISI316L) holding double walled panels and, if required, provided with inspection doors.

4 Casing The casing is built out of a aluminium framework (optional: galvanized steel or welded stainless steel AISI316L) holding double walled panels and, if required, provided with inspection doors. The thickness of the framework is at least 2mm, depending on size and application. The double walled panels are made of galvanized steel (optional: stainless steel AISI316) and insulated with 40mm thermal and acoustic insulation, Rock- wool type 223 cross section, other insulation are possible on request. Sheet thicknesses are available from 1mm up to 2mm. Air handling units outdoors are provided with pitched roof plates and 50mm overhanging eaves. Doors The inspection doors are fitted with polished AISI316 stainless steel locks and hinges which are mounted on the outside of the panels to avoid thermal bridges. Doors that close overpressure sections are provided with a safeguard to prevent dangerous situations. Not self- adhesive EPDM rubbers are used to prevent air leakage. Grounding All components are provided with 16mm 2 earth-bonding. Electric heater The electrical heaters meet the requirements of Lloyds and Veritas. The terminal box is made of galvanized steel and also the casing, the elements are made of inox steel. The connections are sealed to avoid moisture between the jacket and the elements. Because of vibrations, the elements are supported at the ends. The electrical heaters are provided with a maximal temperature protection. The heater complies with protection degree: IP44. The electrical heaters are also available in EX-type, entire heater is fully made of stainless steel AISI316 and complies with classification: Ex ed IIC T3 (optional: zone I and zone II) and protection degree: IP65. Cooling coil The cooling coil is selected according to the project specific air conditions and refrigerant type. Direct expansion, seawater and chilled water are common applied refrigerants. The coil can be produced in Cu/Al, Cu/Cu, CuSn/CuSn, stainless steel/ aluminum or titanium in the case of seawater. An anti-corrosive Poly/Al coating can be applied after manufacturing. If the face- velocity of the coil is higher than 2.5 m/s a Polypropylene mist eliminator is installed. Optionally the mist eliminator is carried out in stainless steel AISI304 or AISI316. The cooling coil is provided with a stainless steel AISI316 frame and positioned above a stainless steel AISI316L drip tray provided with a 1 condensate drain. Heating coil These can be supplied in the same design as the coolers except the heating coils are suitable for steam, hot water or another heating medium. Base frame To support the units during transport and on-site, the air handling units are mounted on a rigid base frame. The base frame is made of hot dipped galvanized mild steel beams or bended 4 mm stainless steel AISI316L U-profiles which are welded by certified welders. The main welds can be exposed to non-destructive testing (NDT) to check on imperfections. Hoisting lugs are standard equipped with a RAL1028 yellow coating. The frames are provided with diagonal positioned earth bosses. Alternatives available on request. Due to continuous product development, Heinen & Hopman reserves the right to introduce alterations without prior notice.

Filters The unit is standard fitted with EU-4 pleated filters that will be mounted in galvanized steel filter frames. The filters are grounded through a detachable clip on the filter frame.

5 Filters The unit is standard fitted with EU-4 pleated filters that will be mounted in galvanized steel filter frames. The filters are grounded through a detachable clip on the filter frame. An inspection door is provided on the inlet side of the filter, so maintenance and inspection takes place on the dirty side. Optionally, the unit can be equipped with ATEX, HEPA filter or coalescer. Weather louvers If the unit takes in fresh air, the unit will be equipped with a weather louver. The inlet section can be performed with a mist eliminator and/or coalescer behind the louver and the intake damper to avoid water infiltration during extreme weather conditions. Dampers Contra rotating dampers, the casing, valves, shafts, levers and connecting rods are made of stainless steel AISI316. The rate of leakage is m3/s/m2 at a pressure difference of 1000 Pascal (tested with a damper with dimensions of 1200x1500 mm.) The valves can be operated manually or by means of an electric servo motor or pneumatic actuator. Air flanges The air flanges are carried out in 4mm to 6mm galvanized steel (optinal: stainless steel), depending on the size and application, and foreseen with a specific-hole pattern. Fans Fans are generally direct driven plug-in type. The impeller consists of coated steel and the base frame is made of stainless steel AISI316. Optionally, stainless steel AISI316 backward curved double inlet centrifugal fans are used. The fan and motor are assembled on a common frame and isolated from the casing by vibration dampers and flexible connections. Fans for Zone 1 or Zone 2 are fitted with brass inlet cones and other measures to reduce the chance of sparks. Access to the fan sections is provided with perforated CE grids for safety. Note: Plug-in type fan till max. 600Pa static pressure and centrifugal fan for higher pressure. Motors ATEX units are standard equipped with 3 phase low voltage 50 Hz and 60 Hz cast iron motors with offshore coating. The motors can be supplied in Zone 1 and Zone 2 version. Controls/wiring The electric wiring consists of flame retardant PVC halogen-free cables both unarmed and armored. For the wiring of the various electrical components from the inside to the outside are standard brass CMP A2 cable glands for unarmored cables installed. In case of armored cables there will be standard E1FX TRI-STAR cable glands used. Optionally, the wiring can be performed on stainless steel AISI316 ship-ladder cable trays. Alternatives available on request. Due to continuous product development, Heinen & Hopman reserves the right to introduce alterations without prior notice.
