FLOW ICE (Slurry Ice)


Process Cooling

Fluid Transporting Latent Heat

Slurry ice has the advantage of high heat transfer rates and can be used very effectively in applications where low flow rates are required, to save pumping cost.  This is only possible with a fluid transporting latent heat.

Very High Cooling Rates

Some process cooling requires fast cooling times during peak loads throughout the working day.  Slurry ice has the advantage of being stored in a buffer tank and can be pumped through indirect cooling jackets or heat exchangers to provide very fast chilling times, thus maximising existing equipment usage to deliver better products and increased production.

Very Effective Secondary Refrigerant

Slurry ice is a very effective secondary refrigerant, with ammonia as the primary refrigerant.  Energy efficiency, in combination with cost effective installations, and the simplicity of slurry ice, pumped as easily as water through heat exchangers, ensures that slurry ice is the most suitable choice.  The use of slurry ice has the advantage of lower circulation rates (up to 5 time lower circulation rates) and pipe diameters of half the diameter, compared to glycol or equivalent secondary refrigerant systems.

Containerised Flow-Ice Systems

A very compact “plug and play” containerised Flow-Ice System.  This system is mobile and all that would be required is power supply and water.  There are two options – the first a 6 metre container with a 10 ton agitated storage space and the second is a 12 metre container with 30 ton agitated storage space.

Flow-Ice Packaged Systems

The standard packaged unit is the most powerful, robust system with the smallest footprint possible.

Thermal Energy Storage

Energy Store – Tank Size

Slurry ice has the advantage of storing energy in the form of ice that can be melted efficiently to maintain constant temperatures during peak load periods.  The size of the tank will depend on the peak load and period of this load along with the operating time of the machine.

Power Supply Restrictions

Slurry ice could also be used in applications were there are power supply restrictions.  The ice machine will produce slurry ice during off-peak times and the peak load problems will be eliminated with the availability of an energy store in the form of slurry ice.

Demand Side Management

Thermal energy storage systems also offer the advantage of minimising energy cost by running equipment during off peak hours and thus eliminating the risk of being penalised with high energy cost penalties during peak hours.

Pipe Remediation Via Pipe Pigging Using Flow Ice

Pipes and pipelines tend to become fouled with many contaminants, including rust-scale and various other detritus and  the use of pumpable Flow-Ice is an effective way to scour pipes without introducing hard “pigs” that may cause structural damage to some pipelines.

Also, being fabricated from various solid materials  – plastics and metals – pigs may be quite expensive to use. Sometimes, solid pigs may be difficult to place, use, and recover.

Flow-Ice is a non-chemical process that scours the internal walls of pipes to remove corrosion or other contamination, via friction, without causing any structural damage to the pipework

This is accomplished using pumpable Flow-Ice (also known as Binary ice or Micro Ice).

Flow-Ice can be introduced into the pipes via fire hydrants and discharged via hydrants at a predetermined distance and location.

This allows the recovery of contaminated debris that has been removed via the ice pigging process. Alternatively the waste stream can be directed into other methods of disposal according to local discharge laws and requirements.

The application of Flow-Ice is not restricted to municipal water supplies, Any pipe that requires flushing and cleaning is a potential candidate.
