- Applications
One technology. Every pipeline that matters.
PolarFlow ice pigging is deployed across nine industries and dozens of pipe materials — wherever flow, hygiene, or efficiency is being lost to build-up.
- Industries
Built for any pipe with a problem.
If it carries fluid and loses performance to build-up, ice pigging is probably the cleanest, fastest fix.
Potable Water
Restore flow, taste and chlorine residual in drinking water mains without taking the network offline for long.
Wastewater & Sewer
Break down struvite, fats and settled solids from rising mains and force mains in a single pass.
Food & Beverage
Sanitary cleans between product changeovers in dairies, breweries, distilleries and beverage lines.
Pharmaceutical
Validated cleaning of WFI loops, purified water systems and process pipework with no chemical residue.
Oil, Gas & Petrochemical
Clear paraffin, wax, asphaltene and product residue from gathering lines and process pipework.
District Heating & Cooling
Remove magnetite, biofilm and sludge to recover heat transfer in DH/DC networks.
Marine & Offshore
Cooling water, ballast and firewater systems cleaned in port without dry-dock downtime.
Hospitals & Healthcare
Reduce Legionella risk and biofilm in domestic hot/cold water systems with minimal disruption.
Power Generation
Service water, raw water intake and cooling circuits scoured to specification between outages.
- Municipal water
Restore water quality without digging up the street.
Discolouration complaints, manganese release, low chlorine residuals — ice pigging clears the root cause in hours, not days, and uses up to 85% less water than traditional flushing.
- Cleans mains from 50 mm to 1,500 mm
- Up to 85% less flushing water vs. unidirectional flushing
- Returns to service the same shift
- No NDMA, no chemical residue, fully potable-safe
- Food & Beverage
Faster changeovers, fewer effluent losses.
Recover product trapped in transfer lines, slash CIP cycle times, and validate cleanliness between SKUs — without scrap, without overrun.
- Recovers up to 99% of in-line product before flush
- Cuts CIP water and chemical use significantly
- Validated for breweries, dairies, juice and spirits
- Compatible with stainless steel, PEX and HDPE
- Oil, Gas & Petrochemical
Remove wax, paraffin and asphaltene — safely.
Conventional pigs get stuck, chemicals create disposal headaches. Ice pigs simply melt if they meet a blockage, eliminating the single biggest operational risk in pipeline cleaning.
- Zero risk of stuck pig
- Handles bends, tees, valves and diameter changes
- No solvent or surfactant disposal
- Suitable for live and isolated assets
- District energy
Recover lost MW from your heat network.
Magnetite and biofilm in DH/DC circuits silently degrade ΔT and pumping efficiency. A single ice pigging campaign typically pays back within one heating season.
- Restores design ΔT and flow rate
- Improves heat exchanger efficiency
- No system drain-down required
- Documented before/after turbidity reports
- Pipe compatibility
Works with the pipes you already have.
Ice is a soft pig — it scours deposits but never abrades the pipe wall, so it’s safe on fragile, lined and legacy materials that mechanical pigging can’t touch.

- What we remove
If it sticks to a pipe wall, ice removes it.
Water networks
- Biofilm and bacterial regrowth
- Iron and manganese deposits
- Sediment and tubercles
- Discolouration particulate
Process & food
- Product residue (beer, milk, juice)
- Fats, oils and grease (FOG)
- CIP scale and limescale
- Yeast and protein build-up
Industrial
- Paraffin and wax
- Asphaltenes
- Magnetite and corrosion products
- Struvite and inorganic scale
- Proven results
A track record across every sector.
Operators choose ice pigging because the numbers hold up — across municipal, industrial and process applications.
