General Description

GEFRAN series 1200 / 1300 digital controllers have
been designed for temperature control in any
applications involving heating or cooling processes.
They represent an exclusive combination of
performance, reliability and applicational flexibility. In
particular, this new line of Gefran temperature
controllers is the ideal solution for application in sectors
where performance and service continuity are
important, including:
• extrusion lines
• injection molding for plastic materials
• thermoformers
• presses for rubber
• wrapping and packaging machines
• processing plant for the food industry
• cooling switchboards
• climatic chambers and test benches
• ovens
• paint plants
• etc.
