Service
Process Systems specializes in servicing Kemp equipment and C.M. Kemp drying and adsorption systems. With more than 25 years of experience dealing with Kemp systems and manufacturer's systems, we can also provide service for other types of adsorption systems.
Parts
Many adsorption systems — especially liquid dehydration, solvent dehydration, and gas drying — have engineered components. Process Systems can help identify specific components and source new replacement parts, particularly for Kemp equipment.
Kemp equipment has been providing systems for over 40 years. Many are still in operation. We can often eliminate the distributor or sales representative, giving customers a direct source for replacement parts.
Many dryers have moisture analyzers to measure dew point. Process Systems works with Cosa Brand Moisture Analyzers and has retrofitted a number of older analyzers with the Cosa Analyzer.
Process Control
Process Systems can help with retrofitting older controls with new PLC (Programmable Logic Controller) panels. We have retrofitted a number of older Kemp ORIAD dryers and PPC DEA dryers with upgraded PLC systems.
PLC systems provide an excellent platform to add moisture analyzers, pressure transmitters, and temperature elements to the control — eliminating mechanical switches and enabling direct moisture indication and control.

All air, gas, and liquids contain moisture in various amounts up to saturation — where just a slight change in temperature or pressure can cause water to condense and create problems in process systems.
Process Systems, LLC provides a full range of drying systems ranging from standard industrial designs to custom-engineered air, gas, and liquid systems. We strive to be flexible in working with our clients to provide the best-suited system for their application.
Key Definitions
Important: Water load doubles for every 10°F rise in inlet temperature to an adsorption air dryer — which can double the required size of the dryer.
Refrigeration Dryers
Mechanical air dryers use refrigeration to reduce the pressure dew point of compressed air. The dryers lower the temperature close to the freezing point of water — about 35°F–39°F — which causes moisture to condense out. The condensed liquid is removed with separators.
There are three kinds of refrigeration dryers: direct expansion types (cycling and non-cycling) and the chiller type.
Direct Expansion — Hot Gas Bypass
At low loads, routes some hot compressed refrigerant from the discharge side back to the inlet, preventing freezing when airflow is low.
Direct Expansion — Thermostatic Controlled
Shuts down under low-load/low-flow conditions. A thermal storage mass continues cooling the air during refrigeration unit shutdown.
Chiller Type
Two-step heat exchange: hot humid air is cooled by chilled water in one exchanger; the warmed water is re-chilled by refrigerant in a second exchanger.
Best suited for: Higher dew point requirements, indoor applications where ambient temperatures are below 35°F, and where low dew points are not a requirement.
Adsorption Dryers
Adsorbents remove moisture from air by attracting and holding water to the surface of their particles, or by ion exchange using an Ion-Exchange Resin.
System Categories
Adsorbent Types
In a classic dynamic adsorption system, there are three distinct zones: the saturated zone (in equilibrium with the incoming fluid), the mass transfer zone, and the active zone where no adsorption has occurred.
Absorption Dryers
Typical absorbents are sodium chloride, calcium chloride, and urea tablets or beads. The deliquescent dryer does not provide a fixed outlet pressure dew point — instead, the dew point varies directly with the dryer inlet temperature.
These dryers can be installed outdoors in combination with aftercoolers to prevent freeze-up in outdoor pipelines and equipment. Typically, they will lower the inlet dew point by 20 degrees.
Note: Process Systems does not recommend this type of system for instrument or process air applications due to potential downstream contamination and poor dew point performance. However, we provide full service support for existing absorption systems.
