Advanced dehumidification technology
The RDO 750 dehumidifier has been designed with a 3-stage heat exchanger which ensures exceptional efficiency of the drying process. Pre-cooling the inlet air with dehumidified exhaust air optimizes the moisture separation process, reducing energy consumption. Secondary heating of the exhaust air eliminates the risk of water vapor condensing outside the installation, and the automatic condensate drain guarantees continuous operation without the need for operator intervention.
Ecological and durable solution
The RDO 750 dehumidifier uses R134a refrigerant and stainless steel heat exchanger. These features ensure high resistance to moisture and minimize the risk of corrosion, which contributes to the long life of the device. Regular drying of compressed air prevents breakdowns and reduces maintenance costs, ensuring the reliability of pneumatic systems in any working environment.
