Reliable and compact Desiccant dryers are often selected for sensitive applications requiring maximum compressed air availability. To ensure the necessary reliability, DC desiccant dryers are therefore built with top-quality materials and components. Long-lasting desiccant tanks Long-lasting desiccant In accordance with the AD regulations, the desiccant tanks are rated for a million load cycles at a 10 bar pressure differential and thus for continuous operation of at least 10 years. Internal stainless steel flow diffusers and corrosion-resistant exterior surfaces contribute to outstanding...

High efficiency - low pressure dew points Achieving pressure dew points below 0 °C is always a challenge. That makes it even more important to draw on our decades of experience in the design of our DC desiccant dryers and use high-quality components throughout. This ensures outstanding energy efficiency across the entire performance range. Long desiccant tanks The radially mounted piping provides a compact system design with a maximum tank length. This maximises the duration of contact between the compressed air and the desiccant, thus ensuring optimal use of the desiccant capacity. It also...

Compared with molecular sieve dryers, for example, DC series dryers typically require up to 20% less purge air to maintain a pressure dew point of -40 °C. In addition, only top-quality desiccants are used, consisting of uniform beads...

High efficiency – low pressure dew points The ECO CONTROL 2 saves considerable energy especially with variable flow rates, pressures or temperatures. The dew point trend recognition control is more cost-effective and secure than conventional dew point controllers since it reacts to changes in the desiccant temperature differential instead of responding only when the pressure dew point at the dryer outlet increases. New measurements and relative temperature difference comparisons are carried out for each new cycle. Since tank switchover occurs only when the desiccant is used to its full...

Stop wasting energy! Heatless regenerating desiccant dryers should always be sized for maximum compressed air flow, the highest possible inlet temperature and minimal operating pressure. This ensures that the desired pressure dew point is maintained across the entire operating range of the compressed air station. Under real-world conditions, however, compressed air needs, ambient temperatures and network pressure will deviate from the originally specified parameters. The ECO CONTROL 2 dew point trend recognition control responds automatically to these variations and adjusts the dryer’s...

Dew point trend recognition control Valve control Switching sequence monitoring ECO CONTROL 2 controls and monitors the valve switching sequence. The correct sequence can also be checked in a manual testing mode. Saving energy with trend recognition For pressure dew points down to -40 °C, maintenance-free temperature sensors monitor the moisture content of the desiccant. The system switches to the purge tank, before the pressure dew point at the dryer outlet rises, only after optimal utilisation of the desiccant, but within 30 minutes. This minimises the need for purge air. Expansion...
