Immersion Heaters for Molten Melting

NEW CENTURY HEATERS

New Century Heaters has engineered our immersion heaters for molten melting. These heaters coupled with specially designed protection tubes provide the most robust and efficient molten metal heat source in the industry.

Heaters Are Single Phase
SAVE UP TO 30% ON ENERGY
CONTROLS AVAILABLE
made in the usa

Our immersion heaters for molten melting heating elements are made of heavy gage ICA wire on cast ceramic cores that guarantee wire spacing to evenly distribute the heat through high density, high conductivity, non-wetting protection tubes.

We use the heaviest gage wire in the industry to provide robust, long-lived immersion heaters for molten melting that can be operated up to 2,000 degrees Fahrenheit. The wire is recessed in separating groves that are precision cast in a ceramic core that is engineered to compliment the mating protection tube. Because of this, the coils can never touch each other and short out. Extra heavy leads are brought out and insulated away from the heater core to provide trouble free connections


Immersion Heaters are the Ideal Solution for:

hOLDING FURNACES
DEGASSING STATIONS
LADLE MELTING FURNACES
HIGH PURITY MELTERS
MOLTEN METAL
FILTER BOXES
AUTOMATIC POUR
SYSTEMS
LOW PRESSURE
FURNACES
TEMPERATURE BOOSTERS IN DIP-WELLS

IMMERSION HEATER SELECTION

Immersion heaters do not super-heat the surface of the molten metal as glow bar and gas fired reverb furnaces do. Super-heating the surface of molten aluminum greatly increases the absorption of hydrogen into the molten aluminum and the creation of aluminum oxides at the surface, many of which become suspended in the melt or sink, only to be riled up from time to time. 

When used in holding furnaces, immersion heaters more efficiently transfer heat into dip wells and degassers. The heat does not have to pass through an insulating layer of oxides on the surface of the melt. The heat source is beneath any separating refractory arch, and is in close proximity to the dip well or degassing head.

Power requirements are typically twenty five to thirty percent less than glow bar furnaces. The reduction in melt loss and improved metal quality over glow bar and gas fired reverb furnaces is significant. Pairing these advantages with extended refractory life provides cost savings for the user.

Immersion heaters virtually eliminate melt loss in melters and since the refractory is never super-heated, the refractory life over glow bar and gas fired reverb holding and melting furnaces is at least doubled. Corundum is eliminated in properly designed immersion heated furnaces.
