KEEP YOUR DEW POINT UNDER CONTROL WITH DEWPURE, THE HIGH PERFORMANCE MOLECULAR SIEVES
Moisture is an invisible factor that directly impacts drying stability and product quality. The effectiveness of a dehumidification system is measured by the dew point of the process air.
To maintain low dew point levels, molecular sieves are typically used to capture moisture.
DewPure, developed by Piovan, is a molecular sieve designed to ensure a stable dew point, delivering consistent and efficient dehumidification over time.
In many plants, moisture directly impacts process stability, product quality, and efficiency. Dryers must therefore be equipped with accurate dew point probes for continuous monitoring and efficient molecular sieves that maximize water adsorption while ensuring thermal and mechanical resistance. However, many sieves on the market lack the mechanical strength to withstand repeated regeneration cycles, leading to structural degradation and reduced dehumidification capacity
WHAT HAPPENS WHEN MOLECULAR SIEVES LOSE THEIR EFFECTIVENESS?
DewPure, high-performance molecular sieves for drying and dehumidification, is designed to ensure more stable drying performance over time.
Adsorption capacity decreases
Less moisture is removed from the process air, affecting dehumidification performance.
Regeneration cycles become less efficient
The system requires more frequent regeneration cycles, increasing energy consumption.
Fine dust may form due to bead wear
In commercial sieves, wear and tear on the balls can cause dust to build up inside the dryer towers, potentially compromising the plant’s performance.
Minimizing sieve aging while maintaining effective dehumidification is the key challenge.
DewPure enhances the drying and dehumidification process through an optimized blend of zeolites.This formulation reduces molecular sieve aging, minimizes dust formation inside dryer towers, and ensures stable, efficient performance over time.
Key Benefits of DewPure molecular sieves:
Special mix of zeolites boosts adsorption capacity and reduces the number of regenerations respect to the typical molecular sieves.
DewPure can retain up to 10% more water than typical molecular sieves, resulting in fewer regeneration cycles and lower energy consumption.
The advanced composition of DewPure helps preserve the performance of molecular sieves over time, reducing dust formation 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
MobileDewP
CleanTech & PureTech
Piovan can supply Mobile DewP, the portable sensor for measuring process air dew point in drying systems and enabling rapid performance checks.
For enhanced protection of the dryer, we recommend installing CleanTech or PureTech filters, depending on the type of resin.
