Dynarad® Melting and Holding Furnaces 

Aluminum Crucible Melting and Holding Furnaces

Since their introduction in 1983, Dynarad aluminum Crucible Furnaces have led the industry in traditional efficiency and metal quality. Our heavy-duty furnaces are built to perform under severe conditions found in foundries and die casting plants.

Rugged MT Series

Dynarad tilting furnaces feature heavily reinforced furnace frames for distortion free tilting to prevent crucible shifting and cracking. Double acting hydraulic cylinders with safety valves prevent uncontrolled return if hydraulic lines are damaged. Unique “on-demand” hydraulic power package starts and stops automatically, eliminating endless running and oil overheating.

MS & EC Series Portable Furnaces

We’ll set up any furnace for portable use to quickly accommodate alloy changes or maintain production when fixed furnaces break down. Portable “packages” include lifting channels for fork trucks, or eyebolts, chains and spreader bars for crane lifting. Control panel is attached and pre-wired to furnace. Heavy-duty electrical cable with a welder type plug and mating receptacle are provided.

Custom Design Furnaces

Have a special need? We specialize in the design and construction of custom furnaces with unusual shapes and configurations to accommodate limited floor space, unique floor plan “footprints”, special casting machine requirements, etc.

Accessories:
  • CRUCIBLE COVERS – a large selection of crucible covers including pneumatically operated dished head covers, pneumatic split Butterfly covers, pneumatic hinged covers, split manual covers and various custom designs.
  • ALTERNATE POWER SUPPLIES – exclusive Piggyback power supply combines the best in 100% solid state control with the time proven durability of a rugged contactor backup system to virtually eliminate power supply downtime. In addition, all furnaces are available with reduced power ratings for holding and/or superheating applications.
  • PROGRAMMABLE TIMERS can be provided for reducing the temperature set-point at night, reducing on-peak demand during the day, or for simply starting the furnace in the early morning.
  • WHEELS AND QUICK DISCONNECTS easily retract furnaces from casting machines or molding lines.
Reliable Power Control

Because StrikoWestofen America’s unique heating element design requires no transformers or complex solid state SCR power supplies, StrikoWestofen America’s power control panel is compact yet rugged and reliable. It is easily installed and serviced by any plant electrician. The tight, dust-free integrity of the NEMA 12 enclosure is maintained since no fans or vents are needed to cool power control components.

Power Level Selector

The optional Power Level Selector is a true load shedding demand control system, which positively limits KW demand to the power level chosen. More than a simple solid state current limiter, the Power Level Selector reduces utility demand charges, regardless of the type of demand meter used by the utility, and extends heating element life. The Power Level Selector instantly converts a melter to a superheater to a highly efficient holder and back again.

Damage resistant parallel element wiring

Each heating element is independently parallel wired and fused. If for some reason an individual heating element is damaged, the rest of the system will continue to function, unlike series connected elements that will shut down the entire heating bank. This feature gives our furnaces the highest “up-time” in the industry. The durability and performance of our heating elements enables StrikoWestofen America to back its elements with a two year warranty.

Thermally efficient multi layered lining

Crucible furnaces use a computer optimized, multi-layered lining system designed with StrikoWestofen America’s own custom software to cut heat losses like a thermos bottle. Old-fashioned monolithic refractories are eliminated to boost furnace efficiency and save energy dollars.

Heavy duty construction

These furnaces are built to handle the severe conditions often found in die casting plants and foundries. Features like extra heavy, warp-proof plate steel furnace covers and heavy welded steel base and side wall construction are standard on all StrikoWestofen America furnaces.

Easy internal access

The crucible and self-supporting, vertically installed heating elements are easily accessible by removing only the furnace cover. Side panel access is not required; furnaces can be positioned close to casting equipment or other furnaces or pit mounted without sacrificing internal accessibility
