LTI Adds Second Heat Treating Furnace

The Red Devil Dual Chamber Furnace is an affordable option for occasional heat treaters looking for durable energy efficient equipment. With both chambers 12 in H x 14 in W x 24 in L, the upper chamber is programmed to heat to 2200 deg F while the lower oven reaches 1200 deg F. Dual Chamber furnaces allow a shop to harden in the upper chamber then temper/draw in the lower oven without waiting for a single chamber unit to cool down.   
The Red Devil Dual Chamber furnace performs capability heat treating to ASTM, AMS, GE and ASME specifications, as well as other solution treatment cycles, aging cycles, post weld heat treat, normalizing, hardening, and tempering requirements. 

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. 

Vermont Custom Gage Installs Heat Treating System

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.
