Goedhart VCI Industrial air coolers for cooling & freezing applications Cu/Al R404A - CO2 engineering for a better world GEA Heat Exchangers Goedhart VCI The extensive range Goedhart VCI single discharge ceiling mounted industrial air coolers are available with capacities between 2,8 and 264,4 kW. The Goedhart VCI air coolers are suitable for cooling and freezing applications and with a wide variety of accessories and options available. The coil block is standard build from aluminium end plates, copper tubes and aluminium fins The fans are arranged for blow-through air configuration for the Goedhart VCI-B and draw-through for the Goedhart VCI-Z (please state which is required when ordering).. The modular design incorporates 5 different sizes of fan, with model options of up to 8 fans per cooler. Type description Goedhart VCI-B 62567 B=blow through Z=draw through Number of rows deep Number of fans Fan diameter [cm] Fins spacing [mm] Coil block · Tube pitch : 50x50 mm straight · Fin spacing : 4, 6, 7, 8, 10 and 12 mm · Material : 15mm o.d copper tube · : aluminium HT-lamellen · Optimized cooling circuits · Standard refrigerant connections are positioned on the left hand side of the unit when looking with the direction of the airflow. · A good thermal contact is achieved by expansion of the tubes into the fin collars, that are also utilised as spacers to provide a constant distance between the fins. · All coolers are pressure tested to 30 bar (lower by cooling mediums) and are supplied with a light over pressure charge of dry nitrogen. · Suitable for all known refrigerants and coolants, with the exception of NH3.

DT1, RH of 85% and 4 pole 3 phase fans connected in D. Influence of Coating on Capacity The use of coated fins, or of a fully coated coil will result in a capacity decrease of approximately 3% Capacity optimisation Since Goedhart tries to limit stock products, we are capable of optimising the circuitry of our evaporators. In order to do this, the following information is needed : · Design capacity · Air volume · Refrigerant · Air on temperature · Evaporating temperature · Liquid temperature before expansion valve. Sound data The mean sound pressure (LpA @ 3m ± 2 dB (A)) each air cooler is a calculated indication value according to the EN13487 standard parallel pipe. Goedhart uses the fan manufacturer's sound power level (LwA) at the inlet side of the fan. Changes to or by the fan or the product, affect the sound, in these cases, consult the manufacturer for the new indication value. In critical sound requirements, we advise you to consult an expert. Defrostsystem: Hot gas defrost: The coil block is suited for hot gas defrost (hot gas supply through the suction header). At an extra price the driptray can be provided with a hotgas/cooling medium spiral. The stainless steel tubes of the hotgas spiral are enclosed in special aluminium profiles that are rigidly secured to the underside of the aluminium inner tray, thus providing a good bond for maximum heat transfer.Just as with electric defrost a distinction is made with hotgas defrost between light defrost load (room temperature about 0°C) and heavy defrost load. Accessories: Standard accessories for the Goedhart VCI air coolers are: · blow-through / draw-through air configuration · Electric defrost, hot gas defrost and/or water defrost · Fan periphery heating · Hinged drip tray. · Insulated drip tray · Insulated hygienic polyester drip tray · Goedhart VCI-Z supplied with bellmouth connection per fan for a longer air throw · Goedhart VCI-B supplied with air diffusor for a longer air throw · Goedhart VCI-B supplied with air diffusor with air operated damper to increase defrost efficiency (airvolume reduced to approx. 90% and capacity reduced to approx. 95%) The accessories are included in the price list. For room temperatures where ice build-up can be expected and where the coilblock can not be defrosted by the room air, Optional extras: electric orAhanostlugitainsgednefrost is necessary.

GEA Goedhart selected a standard fan range of Ziehl Abegg (we reserve the right to alter the manufacturer) which fit perfectly on the Goedhart VCI air coolers. The fans can be supplied in both blow-through and draw-through executions. Against an extra price and with extra delivery times stainless steel guards and EC-fans are available. The motors are standard executed with a thermo contact (TB) and must be connected to prevent motor damages. The maximum allowable working data in the table and on the name plate of the fans are to operate in an air temperature of 20 °C (air density of = 1,2 kg/m3). For air temperatures lower then +20 °C, the current amperage can be calculated by using the diagram multiplication factor, suitable thermal overloads can then be selected. Execution The fans meet the ErP directive. The fans have very good aerodynamic features because of the special impeller geometry. This special impeller geometry gives the fan a low noise level and an high efficiency. 1x230V fans are suitable for a room temperature till -25°C. 3x400V fans are suitable for a room temperature till -40°C. When lower room temperatures are desired, special fans are need. correctiefactor correction factor 1,15 Connections 1,10 Drie-fase motoren / Three-phase motors Y-AANSLUITING / Y-CONNECTION D-AANSLUITING / D-CONNECTION P P 1U,05 V U1 V1 WZ X W1 W2 U2 Y V2 U2 P P UVW Z X U1 V1 W1 W2 U2 Y V2 1,0 20 10 L1 L2 L3 P P 0= Thermisch-1co0ntact -20 P P = Thermo contact -30 -40 L1 L2 L3 = 3Eféanse-fa/ 3sephmaosetoren / lSuicnhgttlee-mpphearsaetumuor t/oarisr t<em3Ap*erature [°C] = 1 fase / 1 phase Tension Protection class Color Speed controlling : 3x400V-50Hz-3 phase : 1x230V-50Hz-1 phase (60Hz execution on request) : IP44 / IP54 : RAL9005 (black) : - 3 Phase motors are suitable for 2-speed regulation by D-Y reconnection. - 3 Phase motors are suitable for frequency controller with all-pole sinus filter. - 1 Phase motors are suitable for phase control and transformator.

Moisture carry over from the coil block: Air throw** (only draw-through execution) When you select VCI-B with a Ø500 mm fan in an application with a high relative humidity and/or defrost with room air, Goedhart advises the use of a fan with a low pitch angle or the draw-through execution VCI-Z. Thus, you will avoid the risk of moisture carry over from the coil block. The fan with a low pitch angle give a reducing of the capacity of approx. 5% and a reduction of the air volume of approx. 10%. The air throw mentioned in the selection table indicated with ** is based on an air temperature of 20°C, blowing under a flat ceiling without any obstruction. The height and air circulation fold of the room can influence the air throw. The air speed at the end of the throw-length is 0,25 m/sec 6 Goedhart VCI 10mm Type VCI 3x400V-50H-4pole (1500 min-1 nom.)
