Reliability, simplicity, solidity

Designed with technologies from the ACT series, the SMAX series make for a great air quality for industrial purposes, with minimum clutter.


    •    electronic condensation drain

    •    minimum clutter

    •    low energy consumption

    •    electronic controller

    •    LED display of dew point

    •    up to 55ºC inlet air temperature

    •    extremely low pressure drop (<150 mbar on avg.)

    •    proportional power regulation for perfect dew point stability

    •    vertical design of the heat exchanger, natural separation of the water through gravity, without risk of backflow

    •    integrated aluminium close-coupled heat exchanger

    •    processing capacity designed to adapt to generic compressor powers

Small but sturdy


A highly efficient monobloc heat exchanger, built entirely out of aluminium, gathers in a unique configuration the five essential functions of the air drying procedure: pre-coling, condensation, separation, draining and compressed air heating.
This heat exchanger diminishes the pressure drop and is an overall energetically very efficient unit.

The dew point is maintained constant thanks to a high quality proportional bypass  regulator valve, specially developed by DANFOSS®. It procure perfect stability and frost-safety, regardless of the dryer’s loading rate.
