Heat Treating: Industry News

Ipsen Awarded U.S. Patent

With the motor relocated outside in ambient air, a step-down transformer is no longer needed for Argon cooling gas, as required by NFPA 86. Maintenance is simplified with easily greased motor bearings, easy motor vibration monitoring, and easy routine maintenance checks. All of this lowers the cost of ownership.
The innovative shaft seal relocates the motor outside of the vacuum chamber, stabilizes operation and extends intervals between rebuilds.

The Model 48-R36 oven is insulated with 6.5 in multi-layered lightweight firebrick and block insulation with a roof lined with ceramic fiber modules, featuring a stainless steel liner which isolates the workload from the heating elements and directs airflow in a horizontal pattern.
The system from Lucifer Furnaces uses an air recirculating oven, salt bath pot furnace and quench tank to produce steel components for their gages.
