Ultra-Efficiency andSustainability MeetAffordabilityArctic Cool High-Efficiency ChillersWith Magnetic Oil-Free Compressors
Better from the ground upArctic Cool Chillers, Ltd. is a division of the Arctic ChillerGroup which includes ArctiChill, Freeze Co and Arctic Cool.With thousands of HVAC and Process chiller installations inNorth America and overseas.With our two manufacturing facilities in Ontario andSouth Carolina, Arctic Cool can offer strong manufacturingcapabilities with a high standard of quality. Both facilitiesare equipped with state of the art performance test labs. Allchillers are run tested at the factory.A Better Overall ApproachThe Arctic Cool engineering people are veterans leveragingthe remarkable Danfoss Turbocor technology. We optimizethe world’s leading Oil-Free magnetic bearing compressortogether with the Genuine Danfoss MCX control system, andheat exchangers designed for industry leading performance.Arctic Cool delivers a compelling combination of innovativeenergy efficient products using ultra-reliable direct OEMcontrols and the best customer support in the industry.Water-Cooled Chillers to 1,400 tonsArctic Cool standard water-cooled chillers are AHRICertified and available from 60 tons to 1,400 tons invarious configurations and with many standard options orenhancements, including economizers, trim-cooling, freecooling and pumping systems. Chiller plants can consist ofseveral networked chillers and related equipment and includeTridium JACE plant controllers.Air-Cooled Chillers to 420 tonsThe air-cooled chiller range includes traditional coil designs orevaporative condensing. Standard chillers are AHRI Certified.The chiller is designed with up to four independent refrigerantcircuits to increase ambient range, provide redundancy andfacilitate compressor staging. All air-cooled chillers areequipped with refrigerant sub-cooler circuits to maximizeperformance. Free cooling is available to achieve optimalenergy efficiency at low ambient conditions. Options includeadiabatic systems to increase efficiency in high ambients andextreme-duty 10,000 Hour Salt-Spray coatings.Modular Chiller RangeHistory of Innovation and QualityWe are one of the pioneers with Turbocor technology, andhave created many innovations around its use in processand HVAC applications. We understand the foundationalrequirement for rock-solid control of the machine.Using either the Genuine Danfoss MCX Adaptive LogicController or Tridium JACE technology, we can properly andsafely provide operation that squeezes capacity and efficiencyfrom the compressor while assuring normalized operation.The controller simply and elegantly provides that sought afterblend of reliability and optimized energy efficiency acrossmultiple chillers, including the control of VSD cooling towerfans and bypass valves. It provides equipment schedulingand chilled water temperature resets for even higher energysavings when loads permit.Modular design chiller systems allow plants to operate andmonitor banks of multiple chiller modules within a single PLCcontrol. This can provide the benefit of system redundancyfor assured up-time and dynamic load balancing by stagingchillers and their refrigeration circuits. Compact Modules fit through doors.Allows for easy tube service.Master/Slave control system.Redundancy and Expandability.Modules can run independently. Single-point electrical and pumping option.NEW ArcticJACETridium ControllersFor larger chillers upto 12 compressors andfor seamless integrationwith our Tridium plantcontrollers.
The Turbocor Phenomenon Two Controller Choices Arctic Cool Chillers are powered by the Oil Free CentrifugalGenuine Danfoss or TridiumTurbocor Compressor. On the Market for a decade now withover 35,000 deployed and more than 55 Million hours ofoperation, Danfoss Turbocor technology advancements enablenew advantages for the HVACR industry.The Danfoss MCX chiller controller is designed by Danfossspecifically for their own Danfoss Turbocor compressor. Thecontroller delivers optimized and self-redundant performancefor up to 32 networked compressors. The MCX manages theoperation of up to eight Turbocor compressors per chiller andavoids surge and choke operation.The ArcticView interface has a built-in Web Server allowingthe building engineer to connect to the chiller remotely and beadvised by email of any critical alarm from the chiller. ArcticCool Chillers are compatible with all BMS protocols.Outstanding Energy EfficiencyThe Arctic Cool chillers industry leading full load and part loadefficiency enables our customers to well exceed ASHRAE 90.1and California Title 24 energy efficiency requirements.Product NomenclatureACW 740DT4022Tube Passes1 - Single Pass2 - Two Pass4 - Four PassTotally Oil-FreeNo oil management hardware, controls or oil-related downtimecosts.

WORLDS BEST VALUE - Water Cooled ChillersArctic Cool air and water cooled chillersrepresent the leading edge of productperformance and proven reliabilityin a wide range of HVAC and processapplications. Our objective is providing theWorlds Best Total Cost of Ownership.Ultra-efficient Danfoss Turbocorcompressors are controlled by GenuineDanfoss controllers developed by Danfossto properly control, stage, optimize andnetwork the compressors.WIDEST PRODUCT RANGE - Water cooled models are availableup to 1,400 nominal tons in vertical stacked designs, low profileside-by-side designs and condenser-less designs for coupling toremote air cooled condensing systems. Single-circuit design isstandard for highest efficiency and multiple circuits is optional.CONTINUOUS ENERGY OPTIMIZATION - Compressor settings,tower fan speed, bypass and system resets are correlated directlywith compressor pressure ratio. The magnetic drive provides performance at lower energy levels than any oil system can attain.With pump staging, fan speed and bypass valve control, a minichiller-plant can be obtained right from the chiller controller.INDEPENDENT TOUCH-SCREEN INTERFACE – The Arctic Coolindustrial-grade touch-screen interface is non-proprietary, widelyavailable anywhere and very reliable. It is fully independent ofthe controller so the chiller operation is not dependent on thescreen - this is a better approach. In fact on Danfoss controllers,owners have redundant chiller operation screens.CHILLER STAGING – Genuine Danfoss or Tridium JACE. Up to 32compressors across eight chillers are properly controlled, stagedand energy-optimized using the high-speed network. Masterslave configuration allows floating redundant master. Equipmentscheduler and load-based set-point resets are built in.ARCTICJACE TRIDIUM OPTION - Niagara Framework native openprotocol controllers are optional and are hardware based not“SoftJace” that requires a middle-ware that runs slower compiledcode. ArcticJACE is true open-protocol and runs in live executionmode for ultimate reliability, visibility and serviceability. NO needfor PC with multiple processors, MS Windows, VNC or added cost.BACKPLANE ELECTRICAL PANEL – All controls are mounted ontomodern backplane for component access ease, neatness of wiringand ease and safety for service technicians. If an I/O fails, ArcticCool can reallocate the I/O without replacing the hardware.Low-Profile, Modular and fieldassembly chillers can facility accessfor almost any installation.

OIL-FREE spells SUSTAINABLEOil changes the heat transfer rate and increases fluid viscosity.It lodges in the tube wall enhancements of heat exchangersand over a few years builds an insulating barrier layer thatprevents optimal heat transfer. ASHRAE proved it in a study.Then in 2001 NIST and DOE confirmed the energy-robbingeffect of oil. Even an industry average of 8% U-value loss hashuge energy implications.Having no oil results in a sustainable system from the firstday through its entire service life.According to the studies with oil and R134a refrigerant: With high viscosity oil as in screws, properties that promote miscibility lead to reductions in heat transfer rates.Very small amounts of oil less than 0.5% show increasedheat transfer rate but large reductions are seen between0.5 and 1.3%. The effect increased linearly with respect tomass with the effect highest between 1.3% and 3.5%.Oil concentrations above 1.3% cause reductions in thebubble size at the tube surface which reduces heat transfer rates in the evaporator.3.5% oil concentration correlates approximately to 8%U-Value loss which reduces the capacity and efficiency ofchillers. This requires either reducing the Suction temperature or raising the chilled water temperature. This is alogarithmic effect.Oil service and oil related repairs are the number oneservice and maintenance cost to owners of chillers withtraditional lubricated compressors.700kW/Ton at AHRI relief conditions.650.600CS Screw.550.500CS CentrifugalVFD OilCentrifugal.450.400.350LoadProfile.300 .250Arctic .700kW/Ton at AHRI relief conditions.650CS Screw.600CS Centrifugal.550Curves IncludeAvg.
