Pyradia has developed the most advanced line of drop bottom ovens for aluminum solution heat treating. These ovens incorporate state of the art insulation, control system and hoist mechanism which make them the most performing and reliable on the market.

Fields of application
- Solution treating
- Annealing
- Preheating
- Aging
- Any process on aluminum components

Rugged construction
Pyradia's drop quench ovens are designed for an intensive and continuous use up to 1 200^oF (650^oC) . The loading and quenching systems are fully automated by PLC. The dual speed electro-mechanical winch system permits a controlled acceleration/deceleration of the load descent and has proven to be much more reliable and sturdy that the commonly used pneumatic systems.

Superior insulation
The insulation consists of 6" of ceramic fiber modules. This high efficiency materiel assures minimum heat loss and heat storage for rapid heat cycling and energy economy. Contrary to layered blanket arrangement, ceramic blocks have a great resistance to high air velocity abrasion. This configuration is extra durable and requires very little if no maintenance.

Best temperature uniformity on the market
The lo-density tubular heating elements are evenly distributed in the air ducts all around the working zone. The high efficiency fans located in the top plenum procure a powerful verticalairflow, which passes evenly through the working area. As a result, the temperature uniformity throughout the working area is within ± 9^oF (5^oC) (or ± 5^oF/3^oC when required), at any given temperature, even during ramp-up. With these exceptional performances, our drop bottom ovens will meet the tighter specifications of the future. They can also be used for aluminum aging at lower temperatures.
