Snap On Tools to Install L & L Oven

“L&L Special Furnace Co. has shipped a model QDD29 economical dual-chamber heat-treating and tempering oven to an equipment provider located in the Midwest. The furnace will ultimately be installed in a Snap On production facility servicing tool and die support within the company’s production line.

The smallest of our dual-chamber furnaces, the QDD series is ideal for various thermal applications. Its compact over/under design saves floor space and provides dependable and reliable heat-treating without the delays of third-party vendors, shipping costs and transit holdups.

The top chamber is primarily deployed for heat-treating tool steels at temperatures up to 2,200°F; the tempering chamber is suited to temperatures up to 1,250°F and has a recirculation baffle that makes it suitable for small aluminum work as well. The hardening and tempering chambers have interior dimensions of 12” wide by 8” high by 24” deep, with total external dimensions of 55” wide by 70” tall by 56” deep.

The QDD29 is controlled with digital single setpoint controls along with overtemperature protection. Solid-state relays drive the heating elements in a simple, robust control circuit.”
