Two-stage compressors are designed to operate at the high input pressures that JT Dryers require. Single-stage air compressors cannot achieve these pressures.
JT Dryers use the Joule-Thomson effect whereby a gas that is expanded becomes very cold. Since cold air cannot carry water the way hot air can, the water then condenses out of the air stream and is collected in the bottom of the dryer. Learn about the JT Refrigeration process HERE.
Yes! JT Dryers produce the same overall performance as Freon-based dryers because we use the same basic method to dry air - cooling it until water carried in the air stream condenses out.
Yes! Anyone with even modest mechanical skills can easily install one of these dryers. View the installation sheet.
Because we use pressure differential, rather than a complex Freon cycle, to cool the air stream, JT Dryers are far simpler than Freon-based designs and, therefore, less expensive to manufacture.
In general, JT Dryers are sized as follows: JT-20 for 3 to 5 HP compressors. JT-40 for 7.5 to 10 HP compressors. JT-80 for 15 to 20 HP compressors. JT-120 for 25 to 30 HP compressors.
The input and output ports of the JT Dryers are sized as follows: JT-20: 1/2" FNPT, JT-40: 3/4" FNPT, JT-80: 1" FNPT, JT-120: 1-1/2" FNPT.
The drain ports of all JT Dryers and our Work Station Traps are 1/2" FNPT.
The maximum output pressure of the master regulator on all JT Dryers is 125 PSI. However, to achieve the best drying performance, the Factory recommends 100 PSI.
Your compressor’s pressure switch should be adjusted to turn off at 175 PSI and turn on at 145 PSI. Unfortunately, nearly every 2-stage compressor has different adjustments for this procedure. Consult the user manual or contact the manufacturer of your compressor for this information.
Many of our customers prefer to save money and use the automatic drains that they have in hand.
JT Dryers are a true air dryer that can remove both liquid water and water vapor (that can condense into liquid water inside the air lines) from the air stream. Work Station Traps remove liquid water only.
JT Dryers are suitable for use with all General Purpose air applications such as: Auto Repair Shops - Body Shops - Machine Shops - Home Workshops - Paint Shops - Plasma Cutters - CNC Machines - Sandblasting - Powder Coating, - Farm Shops - Service Trucks - Dry Cleaners - Dental Labs - Water Jet Cutting - HVAC Systems - Manufacturing Plants - Chemical Plants - Process Equipment - Food Packaging – and More.
The condensate generated by any air compression system is officially classified as Hazardous Waste. It is a violation of both state and federal laws to dump untreated condensate into storm and/or sanitary sewers. Likewise, blowing this discharge into a yard or drainage ditch is also a violation. Fortunately, it’s fairly easy to build a DIY oil/water separator to address this problem. For more information on this, see our technical bulletin Num. 32 Titled “DIY Oil/Water Separator.”
