M A I N T E N A N C EA D V A N T A G E SImproved MaintenanceOversized Access DoorFor enhanced basin accessibility, the Oversized Access Door optionenables maintenance personnel to quickly and easily enter the basinfor float valve adjustment and unit inspection, cleaning andmaintenance.Fan Drive AccessibilityThe drive components of the PMCQ are easily accessed for routinemaintenance from the front of the unit. Bearing grease fittings areextended to the outside of the unit for ease of lubrication. All drivesheaves have been relocated to the front of the fan section and motorsare positioned on a platform base to allow for easy belt tension adjustment.Easy Clean Sloped BasinThe PMCQ drain pan is designed to improve maintenance access and make it easier foroperating technicians to clean. The bottom of the pan is sloped to the unit drain toensure that the basin will completely drain and allow sediment and debris that maycollect in the basin to be easily flushed from the unit. The design helps to preventbuildup of sedimentary deposits, biological films and standing water.Pressurized Water Distribution SystemThe water distribution system is made of schedule 40 PVC pipe and ABS plasticwater diffusers for corrosion protection in this key area. The piping is easilyremovable for cleaning. The water diffusers have a large orifice and are practicallyimpossible to clog. They also have an anti-sludge ring extending into the headersto prevent sediment from building up in the diffuser opening. In addition, thespray branches have threaded end caps to allow easy debris removal.All PMCQ units have as per standard the ZM II Nozzle to ensure that every squaremeter of heat transfer surface receives complete and even water coverage, resultingin maximum thermal performance.ZM II NozzleClean Pan Basin DesignThe basin of the New PMCQ is sloped toward a depressed areawhere the drain is located. With the "Clean Pan" design, it is easyfor a service mechanic to flush the pan.Optionalaccess doorMAINTENANCEStainless Steel StrainersThe EVAPCO standard for many years, the stainless steel straineris one component that is subject to excessive wear and corrosion.With stainless steel construction, this component will last the lifeof the unit.6
O P T I O N A LE Q U I P M E N TTwo Speed MotorsTwo speed fan motors can provide an excellent meansof capacity control. In periods of lightened loads orreduced wet bulb temperatures, the fans can operateat low speed, which will provide about 60% of fullspeed capacity, yet consume only about 15% of thepower compared with high speed. In addition to theenergy savings, the sound levels of the units will begreatly reduced at low speed.Inverter Duty Fan MotorsInverter Duty Fan Motors are available for condenserapplications which utilize variable frequency drivesystems for capacity control. Inverter Duty Fan Motorsoffer totally enclosed premium efficiency constructionwhich is designed for variable frequency driveapplications.Note: Other special motor configurations are availableto meet specific proper requirements. Contact yourlocal EVAPCO sales representative for applicationassistance and motor availability.Remote Sump ConfigurationFor units operating in areas where temperatures maybe very low, or where low temperatures may occurduring periods when the unit is not operating, a sumplocated inside the building is the preferred means ofensuring that the basin water will not freeze. For theseapplications, the condenser will be supplied withoutthe spray pump, suction strainers and all associatedpiping, but with an oversize bottom outlet.Electric Water Level ControlEvaporative condensers may be ordered with anelectric water level control in lieu of the standardmechanical float and make-up assembly. This packageprovides accurate control of water levels and does notrequire field adjustment.Multiple Circuit CoilsCondensers may be supplied with multiple circuit coilsto match various system requirements such as splitsystems, or if a glycol or water circuit is desired forcompressor head cooling.Basin Heater PackageIf a remote sump configuration is not practical, electricbasin heater packages are available to help preventfreeze-up of the basin water. The packages includeelectric heater elements, and a combinationthermostat/low water cutoff.Note: External pumps should be heat traced andinsulated in the field to prevent freezing.Electric HeatersElectric immersion heaters are available factoryinstalled in the basin of the condenser. They are sizedto maintain a +5°C pan water temperature with thefans off and an ambient air temperature of -18°C.They are furnished with a combination thermostat/lowwater protection device to cycle the heater on whenrequired and to prevent the heater elements fromenergizing unless they are completely submerged.All components are in weather proof enclosures foroutdoor use. The heater power contactors and electricwiring are not included as standard.ModelsPMCQ Heater PowerPMCQ-316 to PMCQ-493 8kWPMCQ-476 to PMCQ-740 12PMCQ-734 to PMCQ-986 16PMCQ-952 to PMCQ-1480 24PMCQ-399 to PMCQ-561 10PMCQ-603 to PMCQ-845 14PMCQ-765 to PMCQ-893 16PMCQ-798 to PMCQ-1122 18PMCQ-1206 to PMCQ-1690 30PMCQ-1618 & PMCQ-1786 30OPTIONS7
