MSD Series Membrane Dryers
The MSD Membrane Dryer
The MSD Membrane Dryer “Proven Technology for reliable, dependable performan M 18 Filter MSD Dryer Individual Membrane Tube Membrane Bundle
“The system approach” MSD Dryer Air Purge Water Oil “A coalescing prefilter is NOT an option with a Membrane Dryer! It is an integral part of the system. ” - a famous pneumatic trainer
“The system approach” A good coalescing prefilter is necessary to remove bulk liquids and aerosols of oil and water at the inlet of the membrane dryer. Hydrocarbon (oil) molecules are much larger than water molecules, and will quickly plug the membrane pores, rendering it ineffective. Air Water Oil
Principle of Operation - Membrane Technology MSD Dryer Air Purge Water
The MSD Membrane Dryer “Proven Technology for reliable, dependable performan M 18 Filter MSD Dryer Individual Membrane Tube Membrane Bundle
Cutaway and Close-up of Membrane Module Individual Membrane Tube Membrane Bundle Consists of thousands of individual membrane tubes
Membrane Technology Air (individual membrane tube enlarged for clarity) Membrane Bundle Purge Water Membrane Pores Purge orifice
Membrane pore size allows water to pass, but Nitrogen and Oxygen molecules bond in pairs and are too large to pass. Nitrogen molecules N 2 Oxygen molecules O 2 Water molecules H 2 O Membrane
Oil (hydrocarbon) molecules are much larger than water molecules, and will quickly plug the membrane pores, causing dryer failure. Water molecule Oil molecule Membrane
The partial pressure of water vapor is usually referred to as the vapor pressure. It is the pressure the water vapor would exert if it existed alone at the temperature and volume of the mixture. P = Pa + Pv (k. Pa) Where: P = pressure of atmospheric air Pa= partial pressure of dry air P v=partial pressure of water vapor
Membrane Technology Air (individual membrane tube enlarged for clarity) Purge Water Membrane technology: (A. ) The process is simple. Saturated (wet) air has a higher partial vapor pressure than dry air. Water molecules migrate through the membrane from higher partial vapor pressure to lower partial vapor pressure. Membrane Pores Purge orifice
Membrane Technology Air (individual membrane tube enlarged for clarity) Purge Water Membrane technology: (B. )As air at system pressure expands through the purge orifice, its partial vapor pressure lowers. This air then “sweeps” over the outer surface of the membrane, causing the water molecules (with higher partial vapor pressure) inside the system to migrate across the membrane. Membrane Pores Water molecules migrate through membrane to purge air side Purge orifice

MSD Membrane Dryers Coalescing Prefilters are a must with membrane dryers. Hydrocarbon (oil) molecules will rapidly plug the membrane pores, quickly rendering the membrane ineffective. Automatic mechanical drain removes liquid oil and water contaminants from the system.
Key Features of the MSD Membrane Dryer w/ Prefilter: Mechanical DP indicator Patented Modular Joiner set with mounting bracket Easily serviced, no adjustments OUT IN Purge exhaust has cover 0. 01 micron Coalescing Prefilter Exceeds ISO Class 1 for particulates and oil content Membrane technology tried and proven ISO 8573 -1: 1991(E) Auto float drain

We will add photos of specific applications and installations in the future
Powerpoint presentation uses same graphics as brochure for clarity and reinforcement
. To read this graph: Plot actual application point (dewpoint and adjusted flow rate) on chart. Closest curve DOWN and RIGHT of point is correct model for application. EXAMPLE: 3 SCFM @ 0ºF ADP. Model MSD-03 -KA 1 D is correct model. Front of fold-out page in Brochure 9 CW-DX-233 7/98. Applies to selecting dryers on all four graphs
