1 serie L High performance air handling unit from to m 3 /h General features Available in 18 sizes, capable of covering airfl ow rates from 1000 to approx m³/h, the L series air handling units offer an optimal solution for all systems that demand air-conditioning and air treatment in general, whether it be utilised in a home or industrial situation. For this reason, the units employ a wide range of materials, components and accessories so that every environmental comfort request is satisfied, while respecting fully the technical regulations of the sector. L series air handling units are also selectable by CD-ROM selection program, which offers the user the ability to choose, within the standard size range, various constructive solutions suggesting an infi nite array of eventual compositions, interacting comfortably between each proposed section, in each of those a complete list of accessories is available. The experience and service of LMF Technical Department can help the Customer for the project. They are available in the following versions: L mm panel thickness; L mm panel thickness; L mm panel thickness; L mm panel thickness; L 4H 42 mm panel thickness cleanable type. Constructive features The frame is made from extruded aluminium profiles, connected together by fi breglass-reinforced nylon two-way or three-way joints; the panels, sandwich type, are fastened to the frame using steel screws, not in sight from the inside of the unit; EPDM gasket, threaded into the aluminium profi les, make the structure airtight, while the inspection doors are fi tted with hinges and double handles (closing from the outside/inside) or fully removable type. The unit rests on an aluminium continuous baseframe, ensuring high structural stiffness and enabling the safe transport and on-site moving. The thermal and acoustic insulation is made from 40 kg/ m 3 density polyurethane or 80 kg/m³ density mineral wool and thermal transmission coeffi cient value is 0,38 W/m 2 K (T1 class according to EN 1886) to 1,39 W/m 2 K (T3 class according to EN 1886); average sound attenuation is 23 to 35 db. The material used for panels can be: - galvanized steel - prepainted galvanized steel RAL aluminium alloy - stainless steel (AISI 304 or AISI 316) Fan sections, supplied with safety systems, can have inside high effi ciency forward or backward curved centrifugal fans and one or two speed electric motors; in their specific accessory list, frequency converter and explosion proof motor & fan construction are to be marked. L series allows the selection of all common unit air filters, relating to type, effi ciency class and dimensions (i.e., from G3 fi lters to H13 HEPA fi lters); this fl exibility is also for humidifying systems, both water and steam type. Concerning heat recovery, L series offers the possibility to choose from the following system of heat saving (categories according to EN 308): - crossfl ow heat recovery with aluminium plates; up to 60% effi ciency; category 1 - closed circuit twin or multi remote coils; up to 50% efficiency; category 2a - hygroscopic thermal wheel; up to 85% efficiency; category 3.
