Entry-level automatic control system for kiln drying


Drying Control


HELIOS 2 kiln controller is the evolution of the well-known Helios and improves the performances of its predecessor thanks to a completely renewed electronics, always maintaining a very affordable price.

This instrument is particularly suitable to control small kilns or, generally, in all systems which is necessary to maintain a high standard of quality and to reduce costs:

HELIOS 2 is the instrument with the best price/performance ratio today available on the market. 


Simply by setting the desired drying program, by writing it directly or by recalling a drying program from the memory (a standard one or a program previously saved by the user), Helios2 controller is able to run the drying cycle in a fully automatic way.

HELIOS 2 includes into a single sealed box (IP55) the control panel and the amplifier for the signals coming from the timber probes. For this reason, it must be placed close to the kiln, operation made easier thanks to its extended working temperature range.
