Description

Kirloskar KESe 30, 37, 45, 55 and 55+ Electric Screw Compressor Operation and Maintenance Manual

The Kirloskar KESe 30 37 45 55 55+ Electric Screw Compressor Operation and Maintenance Manual is the package operation and maintenance manual issued for the Kirloskar Pneumatic electric screw compressor range in both fixed speed and VFD versions. It follows the machine from the moment the crate is opened on site through electrical connection, earthing, first start-up, pressure setting and capacity control, and then straight into the scheduled maintenance programme that keeps the package running. Alongside the procedures it carries the technical data sheet, service kit part numbers, exploded part lists and troubleshooting tables for the whole KESe family.

What makes this KESe manual useful is that it does not stop at the theory of the screw compression cycle. The safety chapter alone covers pressure release, fire and explosion risk, moving parts, hot surfaces, toxic and irritating substances and electric shock, then hands over to a site preparation chapter that spells out foundation requirements, the one metre clearance rule, ambient temperature limits, ventilation calculations, ducting pressure drop limits and cooling air flow figures for each model. From there the electrical chapter gives recommended copper and aluminium cable sizes up to 10 m, fuse ratings for 415 V / 50 Hz three-phase supply, the earthing points at the corner pillar and inside the control panel, and the rule that the air oil separator tank earth must be run separately to the site pit. A commissioning checklist and an initial start-up procedure – including the R, Y, B phase reversal check – close the installation half of the book.

Maintenance Schedules and Service Kits

The maintenance section is built around fixed intervals, and the manual gives the parts list for each one rather than a vague instruction to service the machine. The 1000 hour initial service covers the spin-on oil filter element and the scavenge line orifice. The 2000 hour service adds the air suction filter element and cleaning of the choked coolers. The 4000 hour service changes the K-SMART oil, the air oil separator element and its gaskets, and the pipe coupling gasket on the minimum pressure valve. The 8000 hour service adds the MPVL kit, intake valve kit, moisture separator kit, thermostatic valve kit, drive coupling element, O-ring kit and prefilter element. Every stage carries its own Kirloskar part numbers, and the manual repeats the warning about not using Loctite or Teflon tape on the scavenge line and not mixing different oil brands or grades.

Separator, Filter, Oil and Motor Service

Individual step-by-step procedures cover lifting the top cover plate assembly off the air oil separator tank, fitting a new separator element with stapled top and bottom gaskets, and re-torquing the cover bolts diagonally. Pipe coupling service is documented with the smooth-surface requirement, the silicone lubricant film, gasket centring between the pipe grooves and the alternating nut tightening method with the 3/8 UNC – 30 nm torque value. Air filter replacement, oil filter replacement with a film of compressor oil on the seal, oil level checking at the running sight glass, oil change and top up, and the motor greasing routine for 2-pole and 4-pole motors are all covered separately.

Part Lists and Troubleshooting

Nine part list sections break the package down by system – inlet, intake and control, drive, separation, air outlet, lubrication, cooling, airend and electrical – with illustrated figures and part numbers for each item. The troubleshooting chapter works from symptom to probable cause to remedy, covering compressor not starting, frequent loading and unloading, pressure not building, tripping on pressure, temperature or current, high AOS tank temperature and high oil carry over. The mechanical and electrical safety chapter then lists the function of each protective device: the minimum pressure valve, blow down valve, safety relief valve, air filter clog indicator, oil level indicator, overload relay, MCB for fans, line and AOS pressure transmitters, safety temperature trip, airend discharge temperature sensor, single phase monitoring, voltage imbalance monitoring, emergency stop and standby shutdown.

Controller and Storage Coverage

The final third of the manual belongs to the screw compressor controller. It documents the GOC graphic operation controller front panel keys and their LED meanings, the function and system key combinations, the data entry and yes/no selection procedures, the main, status, alarm and I/O screens, the admin, user, maintenance and PID tuning settings, compressor configuration and VFD selection, the DCS register and IOT lists, Modbus RS-485 communication settings and the remote start and stop procedure. Long term storage instructions for the airend and motor, plus the start-up procedure after storage, are included for machines that will sit idle.

This Kirloskar KESe electric screw compressor operation and maintenance manual gives a technician everything needed to install, commission, run and service a KESe 30, KESe 37, KESe 45, KESe 55 or KESe 55+ package correctly, whether it is a fixed speed machine or a VFD unit. Correct oil fill levels, correct fuse and cable sizing, correct separator gasket fitting and correct greasing intervals all protect the airend, the motor and the air oil separator tank from premature failure – and the manual spells out each of those values instead of leaving them to guesswork. The same document also supports fault finding, so a compressor that will not build pressure, keeps tripping or is carrying oil over can be traced back through the troubleshooting tables to the specific valve, transmitter or element responsible. Because it is a PDF, the KESe operation and maintenance manual is delivered instantly after payment with no shipping and no waiting, it opens on any phone, tablet, laptop or workshop computer, and the pages covering the service procedure you are working on can be printed and taken to the machine.
