RTA 301÷801ROOF-TOP WITH SANDWICH PANELS WITHSCREW COMPRESSORS.FROM 97 kW TO 244 kW.UNIT DESCRIPTIONThe outdoor “Roof Top” self-contained air conditioning <strong>unit</strong>s of theRTA series, which can be connected to a duct network for air distribution,are ideal for the air conditioning of large surface areas for publicuse such as halls, shopping centres, cafeterias, restaurants and healthcentres, or for industrial environments such as food processing or preservationcentres.Equipped with extruded aluminium alloy sections and 50mm-thicksandwich panelling, these <strong>unit</strong>s are available in a cooling-only versionand a version with reversible heat pump. They have a high degree ofmodularity and adaptability to every plant-engineering need since, inaddition to the basic versions, it is also possible to add various solutionsfor the air treatment sections: mixing chamber, free cooling, cross-flowheat recuperator, humidifier, hot air generator, etc.The flat or pocket filters help to keep the air quality at a suitable levelin order to guarantee appropriate hygiene standards.VERSIONSRTACooling onlyRTA/WPHeat pumpFEATURES• Structure of base perimeter made of steel sheet elements galvanised, passivetreated and mould folded (3 mm thick). The frame is made of extruded aluminiumalloy profiles connected by 3 way joints. The assembling of the base to theframe is of dual support and grants the walking on the base panels installation ofwhich is effected without sticking out screws. 50 mm thick sandwich panels aremade of prepainted steel sheet; <strong>water</strong> proofing is granted by gaskets having shapememory for perfect seal up even after repeated removals. Section connectionis effected by means of assembling conic stirrups and <strong>water</strong> proofing is grantedby gaskets.• R407C refrigerant.• Electrical board includes: door interlocking isolator; fuses; thermal protectionrelays on compressors; thermo contacts for the fans of the <strong>condensing</strong> <strong>unit</strong>;contactors for the fan motors of the air handling <strong>unit</strong>.• Microprocessor for the automatic control of the <strong>unit</strong>.COMPLEMENTARY SECTIONSSFT Soft bag filter section with efficiency F6-F7-F8SFT/R Rigid bag filter section with efficiency F6-F7-F8UMI/ST Adiabatic humidifier sectionUMI/ES Exothermic steam producerUMI/EN Endothermic steam producerF/MSEndothermic hot air generator with 1-step gas burnerF/BSEndothermic hot air generator with 2-step gas burnerF/MDF/CDEndothermic hot air generator with modulating gas burnerCondensation endothermic hot air generator with modulatinggas burnerACCESSORIESFactory fitted accessories:IMProtection moduleSL Unit silencementCT Condensing control down to 0 °CCC Condensing control down to -20°CRFCooling circuit shut off valvesWS2 2-row <strong>water</strong> coil for heating with three way valveEH Electrical coilSQ Air quality sensorPF Differential pressostat filters controlCP Potential free contactsLoose accessories:MN High and low gaugesCR Remote displayIS RS 485 serial interfaceRP Metallic guards for condenserAGRubber shock absorbers124
