Controller options

Level 1

Plain and simple
The HHL series presents traditional heatless drying technology. Using a simple timed control, these are designed to provide maximum benefit to applications operating at or near full capacity. Automatic, timed bed regeneration cycles provide consistent performance and cost effectiveness.

LX controller

It is a standard PLC controller with a PDP sensor and an energy-saving function.
