PROTHERM-Q

NEXT GENERATION UNIVERSAL PROCESS CONTROLLERS FOR HEAT TREATMENT

PROTHERM-Q is the next-generation controller series in the Protherm family, designed to monitor, control, record, and archive heat treatment processes across single or multiple furnace chambers. Configurable for various batch and continuous furnaces, it supports both new and refurbished installations. Featuring advanced process control, customizable graphics, and a full-color display, PROTHERM-Q models are available with a touchscreen interface. With options for modeling, target control, and detailed PID tuning, these features ensure precision and reliability in treatments, whether implemented as a standalone solution or integrated into an existing system as part of a retrofit.
