Series IDU provides a stable supply of dry air even under high demand conditions with an inlet air temperature up to 176°F. The IDU's stainless steel heat exchanger improves corrosion resistance. Each unit is also equipped with an evaporation thermometer as a standard feature.

SMC's series IDH compact air dryer offers stable, compressed air temperature control with its integrated heater, regulator, dryer, and filter. The IDH air dryer delivers a constant volume of compressed air at the correct temperature, dew point, pressure and cleanliness, regardless of external conditions or seasonal climatic conditions. Due to it's compact size, and the ventilation holes being on the front and top, the IDH can be installed close to a wall or panel.

Optional accessories include: a separately installed power transformer (supplies other than standard power and voltage); dedicated base (integrates a separately installed power transformer and the air dryer); dust-protecting filter set (prevents a decline in the performance of an air dryer); bypass piping set (connecting this set to the air dryer allows a substantial reduction in installation time); foundations bolt set (fixes the air dryer to the foundations); and a piping adapter (converts the thread type of and IN/OUT fitting for an air dryer).
