Cress C336 & C444 Large-Capacity Industrial Furnace – 36″×36″ & 48″×48″ Chambers, 1950 °F Max, Digital PID Control

Description

Built for high-volume thermal processing, the Cress C336 & C444 Industrial Furnaces feature large cubic firebrick-lined chambers with built-in axial-flow fans for consistent temperature distribution. These models support processes from 200 °F to 1950 °F and can be upgraded to 2250 °F with a 4-zone control system.

Constructed with a robust steel angle frame, vertical-lift door with rope seal, and heavy insulation (4½″ brick + 1½″ block), these furnaces offer energy-efficient performance and operator safety. The standard digital electronic control includes process and high-limit settings, solid-state relays, and door safety switches for instant power cutoff.

Highly suitable for applications like large-part heat treating, batch annealing, drying incoming parts, or stress-relief of welded assemblies, they are available in 208/240 V single- or three-phase power and backed by robust warranty and service support.
