1 AirCel process water ChillersUltracool (UC) Series The highest standards in the water is not only used for refreshment! In many Industrial applications, cold water isused to keep the productivity of the machinery at a constant high level. The optimal temperature is oftencritical, as it ensures the correct operation and highest quality of the production the past, fresh water was used freely for cooling production processes. Today, most processes requirecooling water with much closer defined tolerances. water chillers provide cooling in a controlled closedcircuit. This means that the water used for your production processes is reliable,constant, and to a preadjusted temperature in agenerously sized heat exchanger, DonaldsonUltracool process water chillers guarantee asecure and repeatable production process ,while saving you money and protecting theenvironment.

2 All Ultracool water chillers useenvironmentally friendly, non-ozone depletingrefrigerant. Total process security at highefficiency levels makes the Ultracool waterchiller the optimum operation and high reliabilityhave been the cornerstones in the design ofthis high-efficiency process water chillerseries. With over 30 years of expertise inbuilding water chillers and cooling equipment,Donaldson manufacturers a complete processwater chiller line from 1/4 to 360 water chillers stand out from the crowdthrough high quality components and an extensive range of standard features. All units come standard with an antifreeze protection thermostatto prevent freezing of the heat exchanger.

3 Integrated pressure switchesprotect the circuit against high or low pressure swings. Galvanized steel, externally coated with epoxy resin, protects the housings against corrosion even inaggressive surroundings. Ultracool units are also equipped with an internal water tank. The tank stores the chilled water , which isthen pumped to the production process by the integrated pump. This ensures a constant supply of chilledwater even under fluctuating demand. A level switchinside the tank prevents the pump from running ensure safe operation of the water pump for any flow rate, Ultracool chillers are equipped with aninternal water ChillersLeading the Way in water Cooling TechnologyUC MidiUC MiniProcess water ChillersHow the Ultracool WorksHot water enters the Ultracool process water chiller through a water filter (optional for mini units), thenenters the evaporator of the refrigeration circuit where it is cooled to the required water is stored in the internal tank, which is insulated to avoid thermal losses.

4 This tank keeps thetemperature constant even under varying load conditions. A centrifugal pump circulates cold water from the chiller to the calibrated by-pass between the water inlet and outlet ensures correct operation independent of theposition of the outlet are oversized to achieve maximum cooling efficiency at aThe Ultracool condenser andreduced power consumption. 12345 CompressorTankPumpCondenserFreonFilter dryerSight glassaccumulatorFanGaugeLevel switchand indicatorAntifreezethermostatControlther mostatEvaporatorExpansion valvePressure switchPressure switchesBy-passWater outletSLPSHPHPTOTHW ater filter(UC-0060/0240 SP) water inlet1UC Mini Flow SchematicUC-0500 SP models and larger are equipped with two independently working refrigeration circuits.

5 This not onlyincreases the capacity of these chillers , but also provides a certain degree of redundancy in case one circuitneeds water ChillersHighest Quality Even At Low FlowsThe Donaldson Ultracool Mini modelsUC-0010 - 0240 SP cover nine units with coolingperformances between 1/4 and 10 ton. These unitscan be mounted on wheels as an option, whichenables chilling at the point of use, either central in our smallest process waterchillers, we do not compromise onquality. While the flow may be low, the impact onyour process application can be just as critical!
