York 013-04127-000 Corrosion Inhibitor
The York 013-04127-000 Corrosion Inhibitor, 55 Gallon is the bulk drum size of the York inhibitor and drive coolant family used in York liquid-cooled solid state starters (SSS) and liquid-cooled variable speed drives (VSD) on York centrifugal chillers. The same product line is sold in a 5-gallon container (013-04128-000), which supersedes the earlier 5-gallon number 013-03908-000, and in a 1-gallon container (013-04129-000), which replaced the original 1-gallon inhibitor 013-02987-000. The 013-04127-000 is the size for contractors and facilities that service several drives, where one 55-gallon drum covers many annual coolant changes.
A liquid-cooled drive moves the heat of its power electronics out of the cabinet through a closed coolant loop. On York liquid-cooled variable speed drives that loop is built from coolant pumps, an internal cooling coil, a coolant header with a fill plug, a plate heat exchanger, and a 1.5-inch Y-strainer (029-21798-000), joined by hoses and clear tubing. The fluid in that loop works continuously at temperature, so its corrosion inhibitor package is what protects the coil, pumps, and heat exchanger from corrosion and fouling. York’s own parts catalog lists its drive coolant under the preventive-maintenance kit for YK, YS, and YT chillers (all series) and calls for 1 gallon for a solid state starter and 3 gallons for a VSD. The same catalog states that the coolant must be changed annually, or sooner if it has become cloudy or brown, and that coolant should never be reused. At those quantities a single 55-gallon drum covers about eighteen 3-gallon VSD changes or fifty-five 1-gallon starter changes.
Look at the coolant every time the drive is opened for service. Clear fluid at the correct level is normal; cloudy or brown coolant, a falling level, or any leak at the hoses, the coolant header, or the fill plug means the loop needs attention before the drive overheats. To change it, lock out and discharge the drive as York’s service manual directs, drain the old coolant completely, inspect the Y-strainer 029-21798-000 and the hoses, refill through the fill plug, bleed air from the loop as the manual describes, and run the coolant pumps while rechecking the level. Do not mix this coolant with other fluids, transfer it with clean, dedicated equipment, keep the drum sealed and labeled, and read the safety data sheet and wear gloves and eye protection when handling it. A 55-gallon drum ships as a freight item, so plan for truck delivery and a way to unload and move the drum. Dispose of drained coolant according to local regulations.
Key Benefits
- Bulk Size for Fleet Service: One 55-gallon drum supports dozens of starter and VSD coolant changes, which suits chiller service contractors and multi-chiller plants.
- York Part Number Continuity: The 013-04127-000 sits alongside 013-04128-000 (5-gallon) and 013-04129-000 (1-gallon), so one product family covers every container size.
- Corrosion Protection For The Loop: Supplied as an inhibited coolant to protect the cooling coil, pumps, and plate heat exchanger through the annual change interval.
- Matches York’s Maintenance Plan: Fits the annual coolant change York specifies for YK, YS, and YT chiller drives.
Common Questions
- What equipment does it go into? York liquid-cooled solid state starters and variable speed drives on York centrifugal chillers, listed by York under the YK, YS, and YT preventive-maintenance kit. Confirm the coolant your drive uses from its service manual or data label.
- How is 013-04127-000 different from 013-04128-000 and 013-04129-000? The container size: 55 gallons, 5 gallons, and 1 gallon respectively. 013-04128-000 supersedes 013-03908-000, and 013-04129-000 replaced 013-02987-000.
- How often should the coolant be changed? York’s guidance is annually, or sooner if the coolant turns cloudy or brown, and drained coolant should never be reused.
