1 Goedhart VRB / VRZ Industrial air coolers for cooling & freezing applications StSt/Al NH 3 - CO 2 engineering for a better world GEA Heat Exchangers

2 Goedhart VRB/VRZ The range Goedhart VRB/VRZ single discharge ceiling mounted industrial air coolers consists of 902 types with capacities between 3,3 and 236,3 kw. The Goedhart VRB/VRZ 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, stainless steel 304 tubes and aluminium fins. The fans are arranged for blow-through air configuration for the Goedhart VRB and draw-through for the Goedhart VRZ (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 VRB 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 spacings : 4, 6, 7, 8, 10 and 12 mm Material : 15 mm o.d stainless steel 304 tubes : aluminium HT-fins 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 hydraulic 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. Standard the air coolers are suitable for NH 3 - pumpcirculation (ratio 2/4). Casing Construction for ceiling mounting The flush mounting protects against and prevents accumulation of dust and dirt. Casing material of galvanized sheet steel Finishing is standard white epoxy spray (RAL 9003) Bend/header protection by end covers, easy removed for maintenance Defrost by hot gas spiral or electric defrost elements will be fixed to the bottom side of the coil. Stainless steel fasteners. 2

3 General range features Capacity The listed nominal cooling capacities are are based on NH 3, DT1, a 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 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: For room temperatures where ice build-up can be expected and where the coilblock can not be defrosted by the room air, electric or hotgas defrost is necessary. With low temperatures we also advise fan periphery heating. Electrical defrost: The Goedhart VRB and VRZ can be provided with electric defrost. A distinction can be made here between heavy defrost loads for low temperatures and light defrost load for higher temperatures (room temperature approximately 0 C). The stainless steel heater elements are fitted in the coilblock in tubes, which forms a high conductive medium between the heaters and the fins. The driptray heaters are fitted to the underside of the aluminium inner tray with aluminium profiles.the heater elements which are rated for 220/240 V are connected for supply 380/415 V with neutral. The coilblock L1 L2 L3 Connections at1x230v and 3x400V 400V 400V 400V 230V 230V 230V V 200V 200V L1 L2 L3 Connections at 3x400V 400V 400V 400V elements are removable from the end opposite to the refrigerant connections, whilst the tray heater elements can be removed once the outer tray has been taken off. Hotgas defrost: The coilblock can be made suitable for hotgas. 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 VRB/VRZ air coolers are: Electric, hotgas and/or water defrost system. Fan periphery heating. Hinged drip tray. Insulation within the driptray. Insulated hygienic polyester driptray. Goedhart VRZ supplied with bellmouth connection per fan for a longer air throw Goedhart VRB supplied with air diffusor for a longer air throw Goedhart VRB 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. Optional extras: Various optional extras for the VRB/VRZ are available, price and delivery upon request: Insulation discs Feet for floor mounting Coating of the coilblock Fan hood 60 Hz motors EC-fans Single phase motors Over heat protection on the motors Glycol/water/etc. cooling mediums, NH3 dx, R22 dx/pumpsystem. Stainless steel casing Coupling between hotgas spiral and coilblock Other fin spacings Stainless steel 316 tubes Mounting and Maintenance Goedhart VRB/VRZ is delivered on a wooden frame. When on the frame, Goedhart VRB/VRZ can be handled by forklift truck, which makes positioning and installation simple. Refer to our maintenance and installation manual..

4 Fans Because of the flexible construction of the Goedhart VRB/VRZ air cooler, in principle it is possible to deliver with different fans. GEA Goedhart selected a standard fan range of Ziehl Abegg (we reserve the right to alter the manufacturer) which fit perfectly on the Goedhart VRB/VRZ 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 ρ = 1,2 kg/m 3 ). 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 1,10 1,05 1, 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.

6 Correction factors Capacities at DT1: Hereby the capacities are based on NH 3 pump system and DT1. DT1 is the difference between air-on temperature and the evaporation temperature of the cooler. The evaporation temperature is the saturated temperature corresponding to the pressure at the suction outlet of the cooler.the nominal capacities are based on evaporation temperatures of -8 o C and DT1=8K and -25 o C and DT1=7K and light frosting. Capacities for other mediums and systems are avalable upon request. Correction factors for various air-on temperatures and temperature differences (DT1) are as indicated in the table below. The requested capacity must be multiplied by a correction factor from the table, so that a cooler with the resulting nominal capacity can be chosen from the selection tables. Q nominal = factor x Q requested NH 3 light frost = 0.2 mm RH = 85% DT1 Evaporation temperature ( C) K 0-2,5-5 -7, , , , , = gerekend zonder berijping NH 3 normal frost = 0.5 mm RH= 85% DT1 Evaporation temperature ( C) K 0-2,5-5 -7, , , , , Attention! Moisture carry over from the coil block: ATTENTION!!! When making your selection, pay attention to the ratio between the airvolume and capacity. A low volume to capacity ratio results in a wide temperature drop across the coil which cause to dry out (especially on coils with a high number of rows deep). When you select VRB 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 drawthrough execution VRZ. 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%. 6
