Engineering Data & Specifications Marley MC Fluid CoolerMarley / MC Fluid Cooler / Table of Contents Specifications / BaseSpecifications / Options Convenience and Safety OptionsMarley / MC Fluid Cooler Air Movement PackageWater Distribution System StructureThe Marley MC Fluid Cooler is particularly suited to the urban environment, reducing noise while increasing energy efficiency and performance. By keeping the process fluid in a clean, closed loop, and combining the function of a cooling tower and heat exchanger into one system, they provide superior operational and maintenance benefits Marley / MC Fluid CoolerSIDE ELEVATION Dimensions Shipping Weight kgWeight MotorPage Dimensions Shipping Weight kgWeight MotorPage Dimensions Shipping Weight kgWeight MotorVIEW A SUPPORTING STEELModel 80MAX E D C AIR INLET ELEVATIONFluid Cooler Coil Fluid Cooling Recirculating WaterElectric Basin Heaters Indoor Storage TankBlowdown Water TreatmentMarley / MC Fluid Cooler / Specifications Base SpecificationsSpecification Value 3.0Performance WarrantyMarley / MC Fluid Cooler / Specifications Base SpecificationsSpecification Value 4.0CoilMarley / MC Fluid Cooler / Specifications Base SpecificationsSpecification Value 7.0Mechanical EquipmentMarley / MC Fluid Cooler / Specifications Base SpecificationsSpecification Value AccessSpecifications Specification ValueStainless Steel Options Stainless Steel Collection BasinSpecifications Specification ValueConvenience and Safety Options Top Access PlatformSpecifications Specification ValueAccess Door Platform Distribution System Access Door PlatformSpecifications Specification ValueVibration Limit Switch Basin HeaterSpecification Value SpecificationsMarley Premium VFD System Specification Value Specificationsteeth or drive shafts. The VFD shall catch a fan spinning in the reverse direction without tripping. The panel shall include a main disconnect with short circuit pro- tection and external operating handle, lockable in the off position for safety. The system shall include a solid state, PI temperature controller to adjust fre- quency output of the drive in response to the tower fluid temperature. The temperature of the fluid and set point shall be displayed on the door of the control panel. The bypass shall include a complete magnetic bypass circuit with capability to isolate the VFD when in the bypass mode. Transfer to the bypass mode shall be automatic in the event of VFD failure or for specific trip conditions allowing safe transfer of utility voltage to the motor. Automatic bypass with an earth ground condition is not allowed. The bypass contactor shall be cycled on and off while operating in bypass, to maintain the set-pointtemperature of the fluid. The drive design shall be oper- ated as a stand-alonesystem without the need for a BMS system. Operator controls shall be mounted on the front of the enclosure and shall consist of start and stop control, bypass/VFD selector switch, Auto/Manual selector switch, manual speed control, and solid-statetemperature controller. An emergency bypass selector switch internal to the panel allowing the fluid cooler fan motor to be run at full speed shall be furnished. To prevent heating problems in the fluid cooler fan motor and to assure proper gear box lubrication the VFD system shall de energize the motor once 25% motor speed is reached and cooling is no longer required. The VFD shall include de-icinglogic with auto canceling and adjustable time. Speed in De-Icemode shall not exceed 50% motor speed. The fluid cooler manufacturer shall supply VFD start-upassistance. Tower vibration testing throughout the speed range is required to identify and lockout any natu- ral frequency vibration levels which may exceed CTI guidelines Specification Value SpecificationsMiscellaneous Options Sound Control Specification Value SpecificationsDischarge Hood GREGORYS BANK WORCESTER WR3 8AB UNITED KINGDOM 2008 SPX Cooling Technologies uk MCF-TS-08A
