Ingersoll Rand UP6: When to Change the Coolant — And How to Do It Right
The coolant in your Ingersoll Rand UP6 is critical for maintaining proper operating temperatures, protecting internal components, and maximizing efficiency. Old or degraded coolant can lead to overheating, reduced compressor life, and unexpected shutdowns. Here’s how to know when to change it and how to do it correctly.
1. When to change the coolant
Coolant change intervals depend on the type of coolant used and operating conditions. For most UP6 units:
- Change every 4,000 hours or annually. Whichever comes first.
- In harsh environments (high ambient temps, dusty conditions), consider more frequent changes.
2. Signs your coolant needs replacing sooner
- Coolant appears discolored or has a burnt smell.
- Visible sludge or contamination in the coolant circuit.
- Frequent high-temperature shutdown warnings.
3. How to properly change the coolant
- Depressurize and shut down: Ensure the compressor is off, depressurized, and cool before starting.
- Drain the old coolant: Open the drain plug on the separator tank and allow all coolant to drain completely. Dispose of old coolant properly according to local regulations.
- Flush if needed: If contamination or sludge is present, flush the system with a recommended cleaning solution or flush fluid. Repeat as necessary until clean.
-
Close and refill: Close the drain, then refill with the specified Ingersoll Rand coolant to the correct level indicated in the sight glass.
For instance: Many UP6 models use a coolant like SSR Ultra Coolant Replacement, but always verify your original part number before ordering. - Run and recheck: Run the compressor briefly to circulate the new coolant, stop, and check the level again. Top off if necessary.
4. Additional tips
- Always use OEM-equivalent or recommended Ingersoll Rand coolant to ensure compatibility and performance.
- Keep extra coolant on hand to simplify future top-offs or emergency maintenance.
- Record coolant change dates and hour meter readings to stay on schedule and track trends.
- For instance: If you're due for broader preventative maintenance, you might also consider replacing items like the oil filter (54672654) or separator (54749247), depending on your UP6 model and service interval.
