The V300 rapid purger from Parker is designed to safely and efficiently remove non-condenseable gases from ammonia refrigeration systems. The V300 is an improvement over the successful V200 series and offers several new features and benefits.The V300 is equipped with a RS-485 communication port for easy interface to controller data transmission. All of the parameters accessible via the HMI cable are now accessible via the serial channel. Further advancements include extended data logging time and password protection for factory calibration settings. Like its predecessor the V300 can be used with 120 or 240 VAC and can handle from 4 to 20 purge points.Features:Can be used with the 120 or 240 VACRS-485 communication capabilityRecords purge cycles and purge time for up to 12 weeksPassword protection prevents tamperingMultiple language displayFactory calibrated for plug and play functionalityAutomatically adjusts vent pressures based on conditionsEnergy saving sleep mode will activate with the lack of non- condensable gasesProprietary microprocessor control for all sensingIncludes 1/2" Globe-T SW isolation valves for liquid, foul gas and suction linesHandles 4-20 purge pointsCompact Design with equivalent capacity of our V200 modelMade from 100% corrosion free components
