Sample Dryer Basics

Atmo-Seal, Inc., understands the demands of Emissions Sampling. Our engineering experience in this field goes back twenty-plus years. ASE’s DDS Series Sample dryers use time-proven designs and principals to dry, filter and deliver a good-quality sample to your instrumentation.

Our use of two trap-separators remove the moisture at the critical junctures between the first and second stages of drying and at the end of the chilling process. Taking out moisture upstream of the chilling process reduces the risk of “freeze-up” on your sample train.

ASE chiller/dryers us eco-friendly R134A coolant. All wetted parts may be Stainless Steel, Teflon or a hybrid of both, for unmatched design versatility.

Of course, the DDH Dryer series is designed to easily interface with other Atmo-Seal, Inc., Emissions components, giving our customers a system that they can rely on.


A Simple Solution

Atmo-Seal, Inc., also supplies a simple trap separator for sample cooling. Though not as effective as a sample dryer, a fan driven coil and trap separator will remove a significant amount of moisture from an emissions sample. When used in conjunction with a peristaltic pump, this inexpensive solution may remove enough moisture that a fill dryer system is not required. 



As always, Atmo-Seal, Inc., will customize our products to your specifications, without jeopardizing your delivery schedule.
