Coolant Tank Cleaning and Sanitation
Precision Cleaning, System Insight, and Preventive Maintenance — Because Clean Coolant Means #LessDowntime
At Machine Tech, we treat your CNC coolant system as a vital part of your machine’s performance — not an afterthought. Over time, sludge, chips, and bacterial buildup can compromise coolant quality, clog lines, and shorten both tool and coolant life.
Our Coolant Tank Cleaning Service is a comprehensive, technician-led process that goes far beyond a quick rinse. We completely remove, clean, and sanitize your coolant tank while simultaneously inspecting the entire coolant system for wear, leaks, or developing issues that may affect flow and reliability.
🕒 Recommended Service Interval:
We recommend performing a Coolant Tank Cleaning every 6 months to 1 year, depending on machining conditions, material types, and coolant composition.
High-volume shops or those machining aluminum, cast iron, or abrasive materials benefit from semiannual cleaning to maintain coolant quality and reduce bacterial growth.
Step-by-Step Coolant Tank Cleaning & Inspection Process
1. Initial Machine Inspection & Documentation
Before any disassembly begins, we perform a full inspection of your coolant system:
• Assess current coolant and tank condition
• Mark all hoses, fittings, and electrical connections for accurate re-installation
• Capture detailed before-service photos of every connection for documentation
• Visually inspect pumps, seals, hoses, and fittings for potential wear or leaks
This early stage ensures a precise reassembly process — and identifies issues before they escalate into downtime.
2. Safe Disconnection & Tank Removal
Our technician disconnects all hoses, pumps, and wiring, then carefully removes the coolant tank from your machine.
Using professional lifting equipment, we hoist the chip conveyor out of the tank and rest it securely on 4×4 blocks for full cleaning access.
This stage is performed with precision and attention to detail to prevent damage to sensitive components or sensors.
3. Sludge, Chip & Debris Extraction
We manually remove all built-up sludge, chips, and fine metallic debris — restoring unrestricted flow and preventing pump blockage.
This is not a rinse; it’s a full physical clean-out designed to eliminate odor, corrosion, and bacterial contamination.
During this process, we also inspect for signs of corrosion, cracks, or coolant flow obstructions that may need follow-up maintenance.
4. Surface Wipe-Down & System Sanitation
Once cleared, the coolant tank and chip conveyor are thoroughly wiped using industrial-grade towels.
We then apply a specialized sanitizing solution formulated to eliminate bacteria, fungi, and biofilm, ensuring every coolant-contact surface is disinfected and safe for reuse.
This deep cleaning process removes the root cause of coolant odor, contamination, and microbial growth.
5. Pump, Filter & Screen Restoration
Each coolant pump is disassembled, cleaned, and inspected for wear or performance issues.
All screens, strainers, and filters are washed, blown out, and reinstalled to restore unrestricted coolant flow.
Any cracked screens, worn pump seals, or restricted filters are noted and brought to the customer’s attention for repair or replacement recommendations.
6. Re-installation, Refill & Leak Testing
The cleaned components — including the chip conveyor and pumps — are reassembled and reinstalled into the coolant tank.
We then reconnect all hoses and electrical connections, reinstall the tank into the machine, and fill it to the proper level with customer-supplied coolant.
A complete system flow and leak test is conducted to verify operation, circulation, and pressure before completion.
On-Site Time Estimate
Because of the depth and thoroughness of this process, a Coolant Tank Cleaning Service is typically quoted for two days on site per machine.
This allows sufficient time for:
• Full disassembly and tank removal
• Complete cleaning and sanitation
• System inspection and testing
Actual service time may vary depending on the machine configuration, coolant condition, and accessibility.
Simpler setups may be completed in less than two days, while larger or heavily contaminated systems may require the full quoted duration.
⚠️ Coolant Disposal Policy
Machine Tech does not dispose of or remove old coolant fluids.
Customers are responsible for coordinating coolant disposal or recycling through their existing waste management provider.
This ensures environmental compliance and allows us to focus entirely on system restoration and inspection.
Why Routine Coolant Tank Service Matters
Regular cleaning and inspection every 6–12 months helps to:
• Prevent bacterial growth and foul odors
• Maintain coolant clarity and consistency
• Restore proper coolant flow and filtration
• Extend pump and tool life
• Reduce unplanned downtime and maintenance costs
• Detect small issues before they become expensive repairs
A clean and properly maintained coolant system is essential to machine longevity, productivity, and consistent part quality.
