Pipelines cleaned at freezing point.
PolarFlow uses a dense ice slurry to scour pipework from the inside — clearing biofilm, sediment and product residue in a single pass. Faster changeovers, lower water use, zero excavation.

- What is ice pigging?
A solid pig that can never get stuck.
Conventional pigs are rigid foam or polymer projectiles — powerful, but risky. Ice pigs behave like a solid in motion and a liquid when stopped, so they scour pipework with high shear force, then simply melt if pressure is lost.
- Works in pipes from 50 mm to 1,500 mm diameter
- Removes biofilm, scale, sediment and product residue
- Single entry & exit point — minimal disruption
- No risk of a stuck pig, no chemical residues
- Why operators choose ice
Cleaner pipes. Less downtime. Lower cost.
Faster changeovers
Cut cleaning windows from days to hours — sometimes from months to weeks.
Lower water use
Up to 20× less water than conventional flushing, with cleaner discharge.
Zero stuck-pig risk
If the system stops, the pig melts. Your asset stays safe.
No chemicals
Just ice and water — safe for potable systems and the environment.
