AeroMaster XP units represent the top class in the category of air-flow rate up to m 3 /h. 2 Basic information Gold medal for AeroMaster XP The quality of AeroMaster XP units is especially appreciated by our satisfied customers. At the prestigious exhibition Aqua-therm 2002, experts from the field of air-handling systems awarded AeroMaster XP units as the best product in field of air-handling units. Plug fan with free impeller The use of the plug fan with free impeller brings a lot of advantages both with regard to selection and acquisition as well as to the operation of the unit. lower fan price reduced length of unit standard control by frequency converter smaller pressure losses efficiency of up to 85 % (lower operating costs) maintenance-free operation (change of belts is not necessary) clean operation (saves filters) quiet operation Thermal insulation In contrast to comparable units, our units have a casing insulated by rockwool with a density of 110 kg/m 3, which provides perfect thermal casing insulation (class T3 according to EN1886) and reduced heat losses. Economical cooling The units can be designed with water or direct cooling. The direct evaporators can be designed as single- or two-circuit evaporators depending on the required output. Heat recovery The up to 85 % efficiency of the heat exchangers guarantees a fast investment return and long-term savings on operation. Cascade control of the electric heaters Electric heaters with sequential switching lower the power consumption. 3 Construction AeroMaster XP units are characterized by their original frameless construction. Thanks to this, they achieve top parameters according to the European standard EN Casing mechanical strength D2 (M) Netěsnost skříně Filter bypass leakage Thermal insulation Thermal bridging Operating temperature L2 (M), (L1(M) optional) 0,5% (F9) t3 tb3 40 to +40 C Casing acoustic insulation (db/octave band) 16,1/125, 19,1/250 Hz, 27,0/500 Hz, 29,7/1 khz, 30,2/2 khz, 29,3/4 khz, 33,2/8 khz AHU N Range AeroMaster XP Cirrus Original frameless construction The unit is composed of special internal stiffeners and sandwich panels. Their interconnection provides the top parameters. This construction provides key to extraordinary stability and is the key to excellent thermal, fire and acoustic parameters. Strong, well-devised sandwich panels The sandwich panel is composed of 50 mm of non-flammable rockwool of a specific mass of 110 kg/m3 which is inserted between the outside and inside walls made of metal sheets. The width of both walls is 1 mm. Clean inside surfaces The mutual connection of the panels and stiffeners ensures perfectly clean inside surfaces of the unit. Even the standard unit satisfies sanitary standards. The absence of thresholds allows easy cleaning. 4 Construction Easy accessability of all service places is provided by inspection doors in inspection panels. The closing system enables very easy closing of the inspection door. Prepared wiring All electric devices of the unit have connecting terminals on the casing, which simplifies installation and also reduces installation costs. Practical accessories The unit can be completed with a series of accessories which enhance operator s comfort. Internal connection of sections Adjustable legs Inspection window Condensate drainage sets Service door lockable handles Internal illumination Easy removal of the built-in elements Enables their perfect cleaning and is ideal for clean operation: surgical operation rooms, pharmaceutical companies, electrotechnical production etc. 5 Outputs and functions UNIT OUTPUTS Energy performance to air flow velocity correlation of AeroMaster XP air-handling units a+ a b XP ,5 m/s 2 m/s 2,5 m/s 3 m/s 3,5 m/s 4 m/s UNIT SIZES XP 22 XP 17 XP m/s XP XP XP functions Ba s ic f u n c t io n s o f AeroMa s t e r XP u n i t s Function Variant 1 Variant 2 Variant 3 Fans with free impeller in spiral casing Heating water electric gas Cooling direct water integrated Heat recovery plate rotary glycol circuit Humidification steam adiabatic Mixing standard mixing chamber integrated mixing (in plate heat exchanger section) Filtration EU3 EU9 dust grease bad smells and harmful substances Sound attenuation splitter noise attenuators 6 Application of units According to place of installation The units are intended for indoor and outdoor installation in a normal environment.

Mutual ordering The air-handling units AeroMaster XP can be optionally selected so that they suit the conditions provided by the place of installation. The supply and exhaust parts of the standard type can be put together in the following variations: in series, parallel, vertical. Special solutions can be realized after reaching an agreement with the REMAK headquarters. Supply and exhaust, IN SERIES SECTION DIMENSIONS All sections are created by multiples of the basic module of 250 mm in length. This modular concept enables the unit length optimization.
