Oil Reservoir HeaterEdwards model 212 and 412 oil reservoir heaters are recommendedfor pre-heating oil in the reservoir prior to pump start up attemperatures below 55 °F. Below 1 Torr., it will help maintain the oilat a temperature high enough to prevent condensation of watervapour in the oil when running with full gas ballast. The 212 and 412oil reservoir heaters consist of an immersion heater to be inserted intothe oil reservoir and an over-temperature switch with sensing bulb tocontrol power to the heater. The heater arrangement can be factoryor field installed.Vacuum Break SolenoidFeatures & Benefits• 2-way 240 V 3/8 inch FNPT• 2-way 110 V 3/8 inch FNPTOrdering InformationProduct description For pump Order No.Vacuum Break Solenoid All 240 V 085046623All 110 V 085046998Gask-O-SealFeatures & Benefits• For tight joint seals• Combination anodised aluminium retainer with Buna-N seals• Range to 0.0001 micronsOrdering InformationProduct DescriptionOrder No.Gask-O-SealPipe Size (inch)1.5 9003180052 9003180063 9003180074 9003180086 9003180108 90031801110 90031801212 90031801314 90031801416 90031801518 90031801620 90031801724 900318018Flex HoseThe model 820 high vacuum hose from Edwards is an all-plastic hosewith aluminium flanges tough enough for easy handling streamlineuse.
