Depending on the humidity levels and the quantity of outside air required the use of a refrigeration pre-cooling coil may be required. The purpose of this coil is to remove as much moisture as possible before the desiccant dehumidifier.
These systems can be built into your ESC Air Handling Unit, or we can provide Pre Conditioning of Air and Post Conditioning of Air to Package Desiccant Dehumidification units
Desiccant Media Options
PPS Silica Gel is used in most environments and desiccant cooling applications.
PPM Molecular Sieve is used when the inlet air is either hot or alkaline, or a low dew point is required.
PPH Hygienic is used where enhanced bacteriostatic properties are desire.
If the regeneration air can be exhausted that is typically the best solution
This is typically a very good application for sensible heat recovery.
If the air can not be exhausted a post-cooling coil may be required.
