GeneralThe SPCA-RSB series air-cooled water chillers consists of 9models covering capacities from 5,8 up to 31,8kW.It is the end result of a thorough study, and accurate design byexperienced Interklima research and development teams, todevelop a small size chiller series with compact shape, highperformance, and reliability of the highest quality standards.This series meets the highest levels of aesthetic and technicalrequirements using the latest technological innovations includingenvironmentally friendly R407c refrigerant that is Chlorine-freeand has zero ozone depletion potential. SPCA-RSB units aretherefore ideal for installation in urban environments due to theirelegant design, selected materials and low operating sound levels.

CasingAll units use metal parts fabricated from heavy gauge galvanizedsteel sheets, formed to ensure maximum rigidity that guarantees andpreserves the units operation during the years. After fabrication metalparts are degreased, phosphatised, and electrostatically powdercoated with an epoxy-polyester RAL 9002 coating of a thickness of60-70Ì. This fully automatic process ensures superior corrosionresistance against the most aggressive ambient conditions. Thetreatment can successfully withstand a salt spray test of 500 hours,according to ASTM B-117.All components are assembled together using bolts thus avoidingthe need for welding which may harm the galvanization of thesteel, and ensures that the whole assembly can fully withstandadverse weather conditions.The compact footprint of the unit arises from detailed study anddesign by our engineering teams and results in a machine, whichfits easily in restricted areas and is simple and easy to install andmaintain, and has been designed with special fittings for easytransport and lifting.Removable panels with special locks are used to permit access onlyto authorized personnel to internal components of the unit forinspection and maintenance.

CompressorAll units' use low-noise, maintenance free, Hermetic Scrollcompressor with low vibration levels, specially optimized for usewith R407c refrigerant, selected from world class suppliers.They are equipped with a crankcase electrical heater for the oil,and are internally protected against potential overloading orelectrical spikes.The compressors are mounted on special antivibration rubbermounts to eliminate vibration from the unit's operation.

Hydraulic kitAll units are equipped, as standard, with a complete hydraulic kitcomprising of a circulating pump, buffer and expansion tank,automatic fill and make up water valve with manometer, safetyvalve, airvent, water filter, differential water pressure switch, andevacuation valve.

Condenser coil All unit air heat exchangers are manufactured from high quality innergrooved seamless copper tubes according to ASTM B-280, havingan outside diameter of 9,52 mm (3/8"). The fins are manufacturedfrom aluminium and form the secondary extended heat transfersurface. The fins are continuous across the heat exchanger and arefabricated in high precision dedicated press lines. The fin surface iswaffle formed, so as to increase the fin rigidity, and have speciallouvers that help increase heat transfer. The combination ofinternally grooved Copper-tubing and louvered fins has resulted in aheat transfer performance 30% superior to that of a conventionalcoil for this particular application. The assembly of the finned packis achieved by mechanical expansion of the tubes in such a way asto form a perfect mechanical bond with the fins. For this purpose,the fin holes have a peripheral extrusion (collar) of adjustable height.This extrusion serves to define the distance between fins (andconsequently the total heat transfer surface) and to ensure perfectcontact of the fins to the tubes.Alternative fin materials are available upon request such as epoxy- coated aluminium or copper for applications in especiallyaggressive environments.

EvaporatorAll units are equiped with a water - refrigerant Plate HeatExchanger, selected from world class manufacturers.It is made of stainless steel plates (AISI 3161.4401) speciallyformed to achieved a large heat transfer surface and assembledby means of an automatic brazing proccess under vaccum.

Condenser fansAll unit fans are of the axial type, single phase, 6 poles, internallyprotected against potential overheating, silent and suitable foroutdoor installation. Due to the sophisticated aerodynamic designof the blades and inlet cones, as well as the perfect static anddynamic balancing, their operation is completely vibration-free. Thefan-motor assembly has a protective grid against accidentalcontact with moving parts, which is designed according to ISOregulations. Fan motors are of the external rotor type,aerodynamically shaped so as not to interfere with the airflow, and

The SPCA-RSB unit should be installed in a location that meets thefollowing requirements:1. The foundation is strong enough to support the weight of the unit,

and the floor is flat to prevent vibration and noise generation.2. The space around the unit is adequate for servicing and the

minimum space for air inlet and air outlet is available. If severalunits are being installed side by side in parallel, the minimumservice space between them must be taken into account

3. There is no danger of fire due to leakage of inflammable gas.4. Ensure that water cannot cause any damage to the location in

case it drips out the unit.5. Make sure that the air inlet and outlet of the unit are not

positioned towards the main wind direction. Frontal wind willdisturb the operation of the unit. If necessary, use awindscreen to block the wind.

6. In heavy snowfall areas, select an installation site where snowwill not affect operation of the unit.

7. Make sure that the unit mounting base can be fixed directly onconcrete.

8. In order to avoid the transmission of vibration from theoperating unit to its carrying structure, the use of antivibrationmaterial to install under the supports of the unit isrecommended. It is suggested to install a rubber pad betweenthe points of support and the base of the unit, or springantivibration mounts under each point of support of the unit.
