1 PORTLE HILLER4EP2 SERIES Outstanding Performance; pplication Flexibility EP2 Series Portable hillers are designed for 4 to 43 ton applications. Units are available in air-cooled, water-cooled and remote condensers models in a wide range of sizes. Using quality components such as scroll compressors, microchannel condensers, low noise fans, stainless steel brazed plate evaporators and sophisticated controls provide the best available technologies for unmatched performance and reliability in a chiller package. Integrated with R-410 non-ozone depleting refrigerant, the EP2 series functions with the environment in mind. Dependable, Easy-to-Use, Wide Size Range Model EP2-05 (air-cooled, 5 ton capacity) The EP2 Series offers superior performance and innovative technology in a dependable portable chiller package. This series of chillers boasts the best components and technology available for the highest level of performance and flexibility to meet the needs of today s industrial manufacturing environment. Designed for total efficiency, all air-cooled models have tools-free removable door panels for easy access to all components. onair s EP2 air-cooled units also feature high-efficiency, low noise fans with integral condensers for reduced operating noise and increased efficiency. lso included as standard are totally enclosed air over (TEO) motors that contribute to the long life of the chiller. `` vailable with optional touchscreen control The EP2 Series Portable hillers come with a standard controller, with 19 operational and diagnostic lights, or can be upgraded to include the new premium touchscreen controller with operational and diagnostic screens for easier diagnosis of faults. oth controls are easy to operate and completely sealed to protect against contamination from dirt or fluids. `` More standard features The EP2 models come equipped standard with features that other manufacturers would offer as options, features that guarantee long life, simple operation and quality end-results. `` Energy efficient Reliable and energy efficient scroll compressors are used in every EP2 chiller. Units over 20 tons utilize compressor staging for reduced energy use. Save even more energy with the variable speed compressors available on 10-ton and 20-ton ir- ooled and Water-ooled units! See the savings in the Payback section of this spec sheet. These onair chillers save you money by saving energy. `` Extensive warranty In addition to onair s standard one year parts and labor warranty, the EP2 comes with a five year parts warranty for the PL controller and interface, and a lifetime $175 exchange policy after the initial five year warranty period (on the standard board).

4 PORTLE HILLER4EP2 SERIES How it Works Process circulation: Process fluid enters through the From process and enters the evaporator. The process fluid is cooled in the evaporator and is returned to the tank. The pump draws water from the tank and delivers it to the To Process connection where it is distributed to the process load(s) and returned to the chiller. Refrigerant circulation: The evaporator extracts heat from the process fluid. Vaporized refrigerant travels from the evaporator to the compressor, where it is compressed. The high-pressure vapor travels to the condenser. ir or water removes heat from the vapor, condensing it to liquid. This liquid is metered back to the evaporator by the expansion valve (TXV).

5 PORTLE HILLER4EP2 SERIES Options Variable-Speed Scroll ompressors (10 and 20 ton Water-ooled and ir-ooled chillers only) Industrial portable chillers operate in a variety of applications with process heat loads frequently less than 100% of available capacity. With increasing emphasis on energy efficiency and reduced operating costs, we developed a variable-speed scroll compressor option to help improve the efficiency of our industrial portable chillers. Most portable chillers use fixed-speed scroll compressors with hot gas bypass to provide capacity and temperature control. This valve bypasses a portion of the hot discharge refrigerant gas back into the compressor to give the compressor a simulated 100% load situation. Payback 10-Ton ir-ooled Variable-Speed ompressor Option Payback (Years based on $0.10/kWHr power cost) Hours/Year ased on 50 Weeks/Year 4,000 hours/year (16 hours/day, 5 days/week) 6,000 hours/year (24 hours/day, 5 days/week) 8,400 hours/year (24 hours/day, 7 days/week) This works well to keep the compressor running and ready for any fluctuations in the actual process load; however, it runs the compressor at full speed all the time. Our variable-speed scroll compressor technology varies the compressor speed to match the process load. y automatically adjusting the compressor speed, the chiller works only as hard as necessary to provide optimum performance with significantly reduced power use.
