MHD Systems
A New Focus on Energy Efficiency: clean and green energy savings
MHD Systems Technology
Scale control for fluid systems. Fuel savings for fuel systems.
MHD units use magnetic applied-field technology that is scientifically designed, tested and proven over time. They improve performance, save money and reduce environmental impact.
- Successful installations in 42 countries
- Units can be built in any size for specific applications
- Lifespan of 100+ years
- Effective scale control over a mile or more of pipe
- Return on investment in under 1 year
30%Less water & energy use
20–30%Lower HVAC costs
5–10%Lower fuel costs
Product Overview
Two product lines, one proven technology
Scale removal & prevention
High-density rare-earth permanent magnets provide water treatment without chemicals. They remove existing scale, prevent new scale and work on both organic and inorganic scale.
How it works
1
Charged particles
Charged particles soften existing scale.
2
Scale erodes
The softened scale is worn away by the fluid flow.
3
Fine sludge
Small particles settle as fine sludge in the sump and leave through blowdown.
Effective scale control for:
Boilers, condensers & cooling towers (up to 30–40 COCs)
Food processing (up to 4× normal run-time cycles)
Hot water heating & laundry systems
Heat exchangers & cooling systems
Water treatment systems
Chillers, evaporators & scrubbers
HVAC systems
Virtually any fluid or aqueous stream
Fuel savings & lower emissions
The MHD unit spreads apart the hydrocarbon molecules in fuel, which gives a larger surface area. The result is more complete combustion, lower emissions and fuel savings.
- Gas & diesel fired boilers
- Gas & diesel engines
- Gas & diesel generators / co-generation
- Marine propulsion engines
- Ships' service generators
- Off-highway mining trucks
Summary of Benefits
Benefits to industry
Prevents & Removes Scale
Removes existing scale and prevents new scale from forming.
Energy & Fuel Savings
Lower energy, fuel and labour costs.
No Maintenance
No moving parts and no power connections. Simple, fast installation.
Environmentally Safe
Non-polluting. Reduces or eliminates anti-scaling chemicals.
Higher Productivity
Less downtime and better equipment performance.
Long Lifespan
Low capital investment with a lifespan of 100+ years.
Longer Equipment Life
Equipment lasts longer and performs better.
Environmental Compliance
Helps with pollution reduction and environmental compliance.
Environmental Comparison
MHD technology vs. chemical treatment
MHD improves performance, saves money and lowers environmental impact. Chemical treatment brings ongoing costs for chemicals, equipment, labour, storage, handling and disposal.
| Factor | MHD Technology | Chemical Treatment |
|---|---|---|
| Ongoing chemical costs | None | Required |
| Power / electrical connections | None | Energy costs |
| Labour & maintenance | None | Required |
| Storage & handling | Self-contained | Chemical storage |
| Dosage monitoring | Not needed | Monitor & regulate |
| Disposal | Environmentally green | Proper disposal required |
| Lifespan | 100+ years | Ongoing purchases |

US DOE Study & Report, 1980
Geothermal test with MHD unit
U.S. DOE Test Facility, East Mesa, California. Report by Bill J. Witt.
Problems: hard scale in the heat exchanger, cooling tower and plumbing, causing inefficiency, frequent downtime, lost production and higher operating costs.
Unit without magnets
Valves fully clogged
MHD with magnets
Valves fully open, full water flow, no scale buildup
Conclusion: The MHD unit controls scale and stops it from forming in a geothermal system, and extends the life of equipment and components.
