Saetech (Salem Advanced Energy Technologies)
Sáetech’s mission is to provide proven new energy enhancement and conservation technologies for manufacturing, industrial and power generation markets.
What is Multi-Pole Magnetic Technology?
- Green technology that treats fluids with a magnetic field and reduces energy requirements, chemicals for treatment, and emissions
- Water and other fluids pass through a series of alternating reversing polarity fields that are orthogonal to the fluid flow, which redirects the orientation of the charged species and produces physicochemical changes in fluids
Cutaway of a multi-pole unit for scale treatment
Applications of Magnetic Fluid Treatment
- Scale removal
- Replaces most water-softening equipment (U.S. DOE, 1998)
- Commercial boilers, cooling towers
- Ice-makers, steamers, dishwashers, coffee makers, misting nozzles, irrigation systems, car washes, commercial laundries, dental spray units, residential water systems and hot water heaters
- Zebra mussel control
- Natural gas combustion
- Potentially unlimited applications for energy reduction and scale control
The Problem of Natural Gas Combustion
Depletes fossil fuel resource; Produces CO, CO2, and many other pollutants; Degrades health; Contributes to global warming

The Problem of Scale
Hard scale is a major problem worldwide! Scaling reduces the heat transfer performance of equipment. Scaling decreases the flow rate of water through tubes and pipes. Scaling leads to increased energy usage and costs. Energy consumption on heat exchange surfaces can increase by:
- 8.5% for 1/32 inch (0.8 mm) of scale
- 25% for 1/8 inch (3.2 mm) of scale
DOE Boiler Project Summary
Traditional Lime Softening vs Magnetic Technology using NIST BLCC (ver.4.4-97 model)
Assumptions:
- Recirculating boiler with 1,000 gpm flow (1.4 MGD)
- Hard water (350 mg/L as CaCO3)
- Makeup and blowdown = 10% of flow
- Lime sofenting required semi-annual inspections and annual cleaning of heat exchanger.
- $10/ton for delivered lime; $5.80/1,000 ft3 natural gas; $2/gallon for acetic acid
