Cold Weather Compressor Startup: Tips for Reciprocating Units
Cold weather is tough on reciprocating air compressors. Unlike rotary stationary units, which run continuously and handle colder conditions differently, reciprocating compressors are more sensitive to cold starts and require a bit more prep when the temperature drops.
If you’re running a rotary stationary compressor, check out our cold weather tips for stationary compressors. If you use a reciprocating compressor, keep reading for DIY steps to keep yours running strong all winter.
Use the Right Oil for Winter
Thick oil can make your reciprocating pump struggle to turn over on cold mornings.
- Switch to a lower viscosity oil suited for cold weather. Check out our compressor oil options.
- Check levels often during winter to keep friction low and performance high.
Keep Your Compressor Warm
Reciprocating compressors benefit from staying above freezing before startup.
- Store your unit indoors if possible.
- Use safe heating options, like heat lamps or small space heaters, to prevent ice buildup and keep oil flowing freely.
Inspect Air Intake and Lines for Ice
Frozen intake components can choke airflow and stall your compressor.
- Check filters and lines for frost or ice before each use.
- Replace filters as needed. Explore our air filter selection.
Drain Condensate Regularly
Water in your tank can freeze and cause serious damage to components.
- Drain your tank and moisture traps more frequently during cold weather.
- Inspect and replace condensate drains as needed to keep moisture under control.
Check Belts and Pulleys
Cold can cause belts to stiffen or crack, making startup difficult.
- Inspect belts for stiffness, cracks, or fraying.
- Replace any suspect belts with new belts to avoid downtime.
Keep Moving All Winter
With a few simple checks and the right replacement parts, you can keep your reciprocating compressor running reliably through winter. No service visits needed.
