Most in use by the leading manufacturers are national and international standards like DIN, EN, NEN and ASHRAE. Due to this, customers have not been able to make objective product comparisons. To meet the European requirements on EN standards, the European Refrigeration Industry embodied by Eurovent has set standards to guarantee an independent certification procedure for air cooled condensers (based on EN 327) and unit air coolers (based on EN 328). The capacities, as given in the technical documentation, are therefore based on EN 327 (15 K temperature difference between condensing temperature and ambient temperature, ambient temperature 25 C). mêéëëìêé=bèìáéãéåí=aáêéåíáîé=embaf The Pressure Equipment Directive PED applies to all Helpman products. Helpman has been PED certified for Modules B+D. All ODIN coils are pressure tested with dry air at the following pressures: Pos.

3 P déåéê~ä=áåñçêã~íáçå= ODIN stands for a revolutionary new concept in air-cooled condensers and dry coolers. The ODIN range has been designed to fully meet the demands of both installers and end users. installers Modular design, thus short delivery times. Ease of use during transport, installation and maintenance. end users Problem free, long life. Excellent energy and environmental yields. Thus low total cost of ownership. ODIN condensers can be used with both halogen refrigerants, ammonia and CO 2 (CO 2 on request). Nominal condenser capacities 8 up to 204 kw. Air flow up to m 3 /h. ^áê=ñäçï Standard the ODIN will be supplied for vertical air flow (execution V). However, all single coil models (ODIN 1-1**) can be supplied for horizontal air flow (execution H). When ordering without air flow indication, the standard execution (V) will be supplied. `çêêçëáçå=éêçíéåíáçå The ODIN has a high corrosion resistance through selected materials, surface treatment and construction. For application in agressive surroundings (coastal and industrial areas) special designs (C1, C2) are available at an extra charge pí~åç~êç=éêççìåí=åçåñáöìê~íáçå= Finned coil 2, 3 or 4 tube rows deep in air direction ODIN-C and ODIN-D : Cu ripple fin tubing ø 1/2, ODIN-CY and ODIN-DY : stainless steel tubing ø 1/2 Tube pitch 50 x 50 mm triangle Corrugated Alu-fins Fin spacing 2.25 mm.

6 S c~åë All ODIN models are fitted with draw though fans ø560 mm, plastic fan blades and corrosion resistant fan guards. Terminal boxes are provided with two cable inlets M20 x 1.5. The fan motors offer a high energy yiels in combination with very favourable sound characteristics. All fan motors are equipped with a thermal safety device built in the windings. The electrical control should be arranged in such a way that continous on/off switcing of the motors ( tripping ) is prevented. The fans are to be wired using the connection box of the motor. All motors are suitable for frequency fan speed control. 230V motors also suitable for triac fan speed control. Special fan motors on request (application at ambient temperatures above 40 C; 60 Hz motors etc.). qê~åëéçêí All ODIN models are provided with lifting lugs. To avoid damage during hoisting, a hoisting beam can be used. The given angles are to be considered. Beware of shocks during transport and handling. When the condensers are out of use for longer periods, the motors have to be switched on for at least 2 hours every month. Distance m Correction db(a) c~å=ãçíçêë pçìåç=éêéëëìêé=ç_e^f Sound pressure as given in the tables are sound pressure levels in db(a) at 5 m distance in free field conditions. Values may deviate depending on situations at site. The table below gives calculated sound pressure corrections at various distances. The table values on page 4 are merely an indication to the sound pressure level on site. In general, the actual values will turn out higher. In order to calculate the correct sound pressure level in the setup situation, an acoustic calculation will be required based on additional information about surroundings, positioning and applied materials on site. jçìåíáåö Refrigerant pipework are to be soldered free of tension. When connecting more than one condensor in parallel the pressure drop on the refrigerant side has to be considered. mçëáíáçåáåö Condensers should be positioned to meet the following criteria: Exact horizontal setup. Adequate space must be left for free entry to the coil inlet face. No restrictions to the air discharge. No possibility of direct air recirculation. nominal fan speed motor voltage poles absorbed power W adjustment values overload relays A article number /50/3 D /50/ /50/3 Y /400/50/3 Y /50/ /50/3 D /50/3 Y /400/50/3 Y fåëí~ää~íáçå=~åç=ã~áåíéå~ååé For more information on installation and maintenance of air cooled condensers we refer to our brochure nr ( Installation and maintenance instructions for aircooled condensers and dry coolers ), which is issued with every ODIN. It is of utmost importance that all instructions are closely followed up. Therefore brochure is to be kept in a safe place for future reference.

At evaporating temperatures below -20 C the condenser capacity has to be calculated from the compressor capacity at -20 C, or a starting control should be used to protect the compressors from high starting loads.

The correct values depend on system and compresser make. `~é~åáíáéë Evaporating temperature C The nominal capacities mentioned below are for R-404A at t 1 = 15 K and ambient temperatures up to 25 C ( t 1 = difference between condensing and ambient temperature). Capacities are directly proportional with other temperature differences between 10 en 20 K t 1. The refrigerant circuiting is optimised to the selected fan speed. `~é~åáíó=åçåíêçä For the ODIN the capacity can be controlled by cycling one or more fans. Capacity control is also possible by using speed regulated variable phase motors (in combination with an electronic speed control device). The fan compartments are separated by baffle plates.
