Common questions
Why choose the PMT21 over the PMT18?
The PMT21 is the largest chamber in the PMT Series at 21" x 13" x 21", built for the highest-volume batch loads and largest components at the same 2350°F ceiling as the rest of the series.
What applications suit the PMT21 best?
Serious industrial heat treating that needs both volume and intensity — large batch processing, bigger components, and production runs where a smaller PMT model would create a bottleneck.
Can I add gas atmosphere control?
Yes — a Gas Inlet & Flow Meter is available, with an optional solenoid valve for automated control, to reduce oxidation scale during heat treating.
Is the warranty valid if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Paragon dealer, so your PMT21 comes with Paragon's full one-year manufacturer's warranty. Register your kiln within 30 days of delivery to activate coverage.
