York 013-04128-000 Corrosion Inhibitor
The York 013-04128-000 Solid State Starter and VSD Coolant Inhibitor is the factory-specified, premixed coolant for York liquid-cooled solid state starters (SSS) and liquid-cooled variable speed drives (VSD) on York centrifugal chillers. This 5-gallon container is marked premixed, do not dilute, so it goes into the drive coolant loop exactly as supplied, with no water, glycol, or additive mixed in. The 013-04128-000 is the current 5-gallon size and supersedes the earlier 5-gallon number 013-03908-000. York offers the same drive coolant in a 1-gallon container (013-04129-000), which replaced the original 1-gallon inhibitor 013-02987-000, and in a 55-gallon drum (013-04127-000), so the container can be matched to the size of the service job.
A liquid-cooled drive moves the heat of its power electronics out of the cabinet with 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.
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 with 013-04128-000, 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 or dilute it, keep the container sealed and labeled, and read the safety data sheet and wear gloves and eye protection when handling it. Dispose of drained coolant according to local regulations.
Key Benefits
- Factory-Specified Coolant: The coolant York specifies for its liquid-cooled SSS and VSD drives, not a generic substitute, so the loop is filled with the fluid the drive was designed around.
- Premixed, Ready To Pour: Marked premixed, do not dilute, so there is no mixing ratio to get wrong in the field.
- 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.
- 5-Gallon Service Size: Enough for a 3-gallon VSD change or a 1-gallon starter change with fluid left to top off; York also makes 1-gallon (013-04129-000) and 55-gallon (013-04127-000) sizes for other jobs.
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.
- Do I mix it with water or glycol? No. The container is marked premixed, do not dilute; pour it as supplied.
- How often should it be changed? York's guidance is annually, or sooner if the coolant turns cloudy or brown, and drained coolant should never be reused.
