Inductotherm is proud to introduce the latest induction technology -Acutrak®.
This proprietary technology provides faster, cleaner, and more efficient melting of aluminum and other non-ferrous metals.
MORE EFFICIENT
Acutrak® delivers the most energy directly to the crucible with molten metal. This makes Acutrak® more efficient than any furnace on the market today.
|
AIR-COOLED
Furnace energy losses are so low that even water cooling systems have become unnecessary. All components are air-cooled.
LOW OPERATIONAL COST
The automatic control system raises the metal temperature to the set point. Then it cuts the power to about 5% to keep the metal hot. The holding energy cost is just pennies per hour.
FASTER MELTING
Acutrak® applies electrical energy directly into a crucible with molten metal. High power density (150 kW/ton) assures quick melting. |
CLEANER HEAT
Acutrak® applies electrical energy directly into a crucible with molten metal, eliminating the need for fragile electrical filaments and fuel burners.
EXCEPTIONAL METAL QUALITY
Clean induction technology guarantees metal of exceptional purity and at the highest temperature. Metal loss is minimal.
EASIER TO INSTALL
Acutrak® furnaces are compact and requires minimal effort to install:
Place - Connect - Run.
PRECISE TEMPERATURE CONTROL
The metal is heated evenly and to precise temperature with minimal overshoot.
HIGHLY RELIABLE
The rugged construction of Acutrak® assures high reliability. A crucible with molten metal is the only hot component in the entire system.
WIDE BODY FURNACE
Acutrak® offers large melt diameter for easy ladling and charging.
FASTER, CLEANER, AND MORE ECONOMICAL TO PRODUCE HIGHER QUALITY ALUMINUM METAL - THIS IS INDUCTOTHERM'S NEWEST Acutrak® TECHNOLOGY.
