Description:

The QDD Series Dual Chamber Heat Treating furnaces feature a high heat chamber for hardening and a recirculating tempering oven. The over/under configuration saves floor space. The hardening furnace is mounted on top with the tempering oven below. Agitated and heated quench tanks are optional. The tempering oven features a fan and recirculation muffle for high uniformity.

The QDD29 reaches 2200°F/1200°C in the hardening chamber, while the QDD124 and QDD126 reach 2350°F/1285°C. The maximum temperature in the bottom recirculation oven is 1250°F/675°C for all three models.

Both chambers are controlled with simple but powerful digital program controls and backed up with high limit safety controls. The controls are made in the USA by a major supplier to our ceramic kiln division and have proven their worth in these heat treating furnaces.
