VT Series Vacuum Tempering Furnaces
Tempering is a process primarily used to increase the toughness of hardened ferrous-alloy parts. The tempering process is typically applied after a hardening process.
SECO/VACUUM’s VT series is an advanced cold-wall vacuum tempering furnace available in horizontal and vertical configurations.
The VT model’s compact design, with recirculation blower and heat exchanger configured to fit within the same footprint, requires minimum floor space. The vacuum tempering temperatures are achievable with furnaces capable of higher temperature vacuum heat-treating processes, but allocating those furnace resources for tempering is not always achieving optimal ROI. The tempering phase is often the bottleneck of a more comprehensive overall heat treatment. The VT furnace eliminates that bottleneck and frees up more advanced furnaces to spend more time on more advanced processes.
SECO/VACUUM’s line of Vacuum Tempering Furnaces is designed for quick and efficient vacuum tempering. Convection heating, gas cooling, and powerful vacuum pumping allow this tempering furnace to reach process temperatures and conditions and return to room temperature quickly, enabling smoother heat-treat process flow at an often-congested stage of the overall heat-treat process. Graphite felt insulation and metal heating elements provide long, reliable service in this heavy-duty furnace. The heating chamber design guarantees the best temperature uniformity within the working area.

The VT is SECO/VACUUM’s most popular tempering model. It is a single chamber horizontal vacuum tempering furnace with a workload size that complies with industrial standards related to heat treatment equipment and has sold many hundreds of units worldwide. It comes with a full range of options and accessories for performing a wide range of functions for heat treaters and can be customized for special functions.
The furnace is completely assembled, leak tested, and then dismantled as required for shipment. The entire system will be ready for operation after re-assembly, interconnection of subsystems and connection to utilities in the PURCHASER’s plant, as required. Equipment manuals with operation and maintenance instructions, spare parts lists, and all necessary maintenance drawings will be provided.
