Keep Your Coolant. Cut Your Costs. Meet Big Sky Decon’s CDU.
Updated: Oct 8
What would your shop save if you could extend the life of your coolant while cutting disposal costs, maintenance labor, and machine downtime?
Big Sky Decon’s CDU
Big Sky Decon’s Coolant Decontamination Unit (CDU) brings a new approach to coolant maintenance: a skimmer, deodorizer, and coolant cleaner in one portable system. It removes tramp oil and treats bacteria responsible for that familiar rotten egg smell, helping you keep coolant in service longer.


Clients using Big Sky Decon’s CDU have reported savings of more than $10,000 a year through reduced coolant replacement, disposal, and maintenance costs.
The CDU helps your shop:
Spend less on coolant: Extend coolant life and reduce the need for full change-outs.
Reduce disposal and labor costs: Skim off unwanted oil and maintain coolant in-house.
Keep production moving: Treat coolant while machines run, or during nights and weekends.
Control foul odors: Target the microbial contamination behind unpleasant coolant smells.
Designed for mills, lathes, drill presses, saws, and other equipment with accessible coolant reservoirs, the CDU fits into your existing maintenance routine. Routine coolant monitoring and top-offs remain part of that process.
We’ve attached a product sheet with more information. Reply with how many machines your shop runs and how often you replace coolant, and we can discuss where the CDU could help you save.
Watch how this unit works in the video below!
If you operate a machine shop, manufacturing facility, or CNC operation, the CDU could significantly reduce coolant maintenance costs.
