KEEP YOUR DEW POINT UNDER CONTROL
WITH NEW DEWPURE MOLECULAR SIEVES
Moisture is an invisible variable that directly affects drying stability and product quality.
The key indicator of an efficient drying system is the Dew Point of the process air.
DewPure molecular sieves help maintain a stable dew point, ensuring reliable and efficient dehumidification over time.
In many plants, moisture is an “invisible” variable that directly affects process stability, product quality and operational efficiency. Over time, molecular sieves inside the drying system are exposed to thermal stress and continuous airflow. As they age, their performance can gradually decline, impacting the overall efficiency of the dehumidification process.
WHAT HAPPENS WHEN MOLECULAR SIEVES LOSE THEIR EFFECTIVENESS?
To address these challenges, Piovan has developed DewPure, high-performance molecular sieves for drying and dehumidification, designed to ensure more stable drying performance over time.
Adsorption capacity decreases
Less moisture is removed from the process air, affecting drying performance.
Regeneration cycles become less efficient
The system requires more frequent regeneration cycles, increasing energy consumption.
Fine dust may form due to bead wear
Wear of the beads can generate dust inside the dryer towers, potentially affecting system performance.
Aging sieves can compromise drying performance. DewPure is designed to prevent it.
DewPure, developed by Piovan, enhances the drying and dehumidification process by using an optimized blend of zeolites. This formulation reduces the aging effect of molecular sieves, limits dust formation inside dryer towers, and ensures stable, efficient drying over time.
Key Benefits of DewPure molecolar sieves:
HIGH-PERFORMANCE MOLECULAR SIEVES
Special mix of zeolites boosts adsorption capacity and reduces regeneration time for more stable and efficient drying.
DewPure can retains up to 10% more water than standard molecular sieves, resulting in fewer regeneration cycles and lower energy consumption.
UP TO 10% HIGHER WATER ADSORPTION CAPACITY
REDUCED AGING EFFECT
The advanced composition of DewPure helps preserve the performance of molecular sieves over time, reducing the aging effect and ensuring more stable drying conditions.
DewPure molecular sieves are composed of synthetic aluminosilicates.
Pore size: 9–10 Å
Beads size range: 3–5 mm
