The Regens are used for drying air in Storage Tanks or Pneumatic Conveying Systems and are beneficial in the drying of hygroscopic (water-absorbing) resins. These Dryers remove water from the air by passing it through a desiccant that absorbs moisture.
Features
The Regens consist mainly of two cylinders containing desiccant, connected by a valve system.
Operation
When the desiccant in the first cylinder is saturated, the air flow can be switched to the cylinder containing the dried desiccant.
Dessicant Types
- Silica gel (an oxide of silica)
- Alumina (aluminum oxide)
- Calcium sulfate (the anhydrous form of gypsum).
Costs
Most Expensive
Heatless Regens run a portion of dried compressed air through the previously utilized cylinder to extract moisture from its desiccant.
Least Expensive
Heated purge regenerative Regens use less air than the heatless variety in addition to heat, which helps the air carry away more water as it passes through the saturated desiccant.
Best Compromise
Heated blower purge regenerative Regens use air from outside the dryer that is heated and sent through the water-saturated desiccant for drying.
Types
There are different types of regenerative regens. These are:
- Small Heatless Regens
- Large Heatless Regens
- Compact Heatless Regens
- Mini Heatless Regens
