The heatless type is the most popular, due to its inherent advantages of high reliability and low maintenance.
The desiccant used IRD dryers have been selected basis our forty plus years of experience in the design and manufacturing of Desiccant Dryers. The vessels have been designed specifically for this service. Vessel diameters have been chosen to allow a minimum of five (5) seconds contact time, which is essential for complete moisture adsorption and consistent dew-points. Air velocity through the dryer has been conservatively designed at less than fifty-five feet per minute, minimizing desiccant fluidization and dusting, and resulting in high dryer reliability.
Ingersoll-Rand’s IRD heatless desiccant dryers are designed to produce a consistent -40°F (-40°C) dewpoint compressed air. Optional IRD dryers for -100°F (-70°C) are also available.
Heatless air dryer works with elements of adsorption & regeneration, which take place due to differing vapor pressure. Desiccants adsorb moisture at atmospheric pressure with part of dry air coming from air outlet of the dryer. The two towers process by turns to provide dry air to distribution system. 10 minutes standard cycle, dryer cycles are controlled by a timer.
And we can also supply the option functions as below:
l Digital Dew Point Monitor
l PLC Controller With Connection Port
l Without Failure To Shift Alarm -DF1, -RS485, -MODBUS
l Including Failure To Shift Alarm -DF1, -RS485, -MODBUS
l Dew Point Demand Control
英格索兰再生式干燥机中使用的吸附剂是根据生产厂家超过40年的设计和生产经验而选用的。压力容器的容积能够允许压缩空气有不少于5秒的吸附剂接触时间。这个接触时间，是保证饱和湿空气被干燥并达到和维持设定的压力露点的必要条件。压缩空气通过干燥机的速度一般小于55英寸每分钟，从而减少吸附剂的液化和粉碎的可能性，加强干燥机的可靠性。
无热再生式干燥机是利用变压吸附的原理，是干燥剂在管网压力下吸附，然后在切换到大气压力下吸附，并从干燥机出口引回一部分干燥空气对干燥剂进一步净化再生。双塔交替并行以上过程，并向用气点提供干燥的压缩空气。
2.3 Heated Regenerative Dryer Features
The desiccant used IRD dryers have been selected basis our forty plus years of experience in the design and manufacturing of Desiccant Dryers. The vessels have been designed specifically for this service. Vessel diameters have been chosen to allow a minimum of five (5) seconds contact time, which is essential for complete moisture adsorption and consistent dew-points. Air velocity through the dryer has been conservatively designed at less than fifty-five feet per minute, minimizing desiccant fluidization and dusting, and resulting in high dryer reliability.
Externally heated air dryer adds a heater based on IRED dryer to heat the purge air. It not only benefits the regeneration effect but also decreases regeneration purge loss. 8 hours standard cycle, dryer cycles are controlled by a timer.
And we can also supply the option functions as below:
l Digital Dew Point Monitor
l PLC Controller With Connection Port
l Without Failure To Shift Alarm -DF1, -RS485, -MODBUS
l Including Failure To Shift Alarm -DF1, -RS485, -MODBUS
l Dew Point Demand Control
Dew Point Demand Control:
The Dew Point is energy conservation method that can extend the drying cycle without extra purging. During periods of lower moisture loads, the Dew Point Demand system offers, in one compact package, the utmost in flexibility and accuracy sensing the actual dew point at the outlet of the dryer, at the end of the drying cycle, and extends the drying cycle until the preset adjustable dew point set-point is reached. During this extended drying cycle the purge valves are closed and the opposite tower is pressurized and prepared for the drying cycle. The dew point demand option consists of the following: Digital Dew Point Display, Adjustable Set Points, Demand Cycle Light, High Humidity Alarm Light With Dry Contact, 4~20mA Output for Remote Annunciation.
英格索兰再生式干燥机中使用的吸附剂是根据生产厂家超过40年的设计和生产经验而选用的。压力容器的容积能够允许压缩空气有不少于5秒的吸附剂接触时间。这个接触时间，是保证饱和湿空气被干燥并达到和维持设定的压力露点的必要条件。压缩空气通过干燥机的速度一般小于55英寸每分钟，从而减少吸附剂的液化和粉碎的可能性，加强干燥机的可靠性。
微热再生式干燥机在无热再生干燥机的基础上增加一只加热器，使用来再生的气流在升高温度后对于干燥剂进行加热再生，即可提高再生的效果，又可减少再生耗气量。
露点控制功能（在线露点检测及调节再生时间）：露点控制是为了能节能，当露点仪检测到出口气流露点低于（即满足）用户设定值时，可编程控制器（PLC）自动延长干燥塔的工作时间，同时停止再生塔的再生。而当露点仪检测到出口气流露点高于用户设定值时，PLC自动控制干燥塔、再生塔立刻进行切换，进入下一个正常循环周期。该功能包括：数字显示露点、可设定的控制点、露点控制指示灯、高露点报警指示灯及报警信号（无源触电）、输出露点信号（4-20mA的电流信号）。
2.4 TZ Type -- Heatless
The desiccants used in TZ dryers have been selected basis our thirty plus years of experience in the design and manufacturing of Desiccant Dryers.
The vessels have been designed specifically for this service. Vessel diameters have been chosen to allow a minimum of five (5) seconds contact time,
which is essential for complete moisture adsorption and consistent dew-points.
Air velocity through the dryer has been conservatively designed at less than fifty-five feet per minute, minimizing desiccant fluidization and dusting, and resulting in high dryer reliability.
Ingersoll-Rand’s TZ heatless desiccant dryers are designed to produce a consistent -40°F (-40°C) dewpoint compressed air.
Optional TZ dryers for -100°F (-73°C) are also available.
l Exclusive Non-Lubricated Switching Valves
1. Extremely long and trouble-free service life. Our valves have been tested for more than 500,000 cycles without a problem, the equivalent of 5 years continuous operation. We are so confident of this design, we offer a five year warranty on valve components.
2. Corrosion-resistant materials are used on all valve components, both internal and external.
3. Continued compressed air flow, even with loss of electrical power to the dryer.
4. Automatic float drain valve (TZ100 - TZ1200)
5. Coalescing/particulate prefilter is provided as standard to remove liquid moisture and oil down to .01 PPMW and particulates down to .01 micron with an efficiency of 99.999% D.O.P. (mounted on models TZ100-TZ600, shipped loose on TZ820 and larger). Particulate afterfilter is supplied as standard to remove any desiccant dust that may have resulted from the drying process. Particulate filter removes particles 1 micron and larger with a 99.99% efficiency (mounted on models TZ100-TZ600, shipped loose on models TZ820 and larger).
6. Upflow drying, which protects the desiccant bed by minimizing the effects of water accidentally hitting the desiccant beads.
l Energy Management System
TZ heatless dryers provide a continuous supply of dry compressed air by automatically cycling the flow of air through two desiccant beds. While one bed is adsorbing moisture from the inlet air, the other bed is being regenerated by a portion of the dried air. The normal cycle, or Fixed Cycle, of a heatless dryer is 10 minutes. Each desiccant chamber is in service for 5 minutes, followed by a 5- minute regeneration cycle. The dryer will be sized to deliver a -40°C/F PDP. If inlet water loading to the dryer is less than the dryer is sized for then the desiccant bed will be underused.
1. EMS is “fail-safe.” Any hygrometer probe failure will force dryer to revert to fixed cycle and high humidity light will flash onand off repeatedly.
2. Fixed cycle/EMS mode selector switch.Dryer can be operated in fixed cycle while hygrometer is serviced.
3. Switch Failure Alarm and Light
4. High Humidity Alarm and Light
5. Nema 4 Enclosure
6. Eliminates waste of compressed air
7. A precision digital hygrometer and aluminum oxide sensor measures outlet dew point.
8. Panel mounted direct reading dew point meter.
9. Field adjustable set points for high and low dew point alarm set points.
10. Fast acting aluminum oxide sensor with a dew point range of +68°F to -112°F.
4 - 20 mA output Probe can be calibrated in the field.
2.5 The Others
l For instance silica gels are well suited for use in taking water vapor from air with high relative humidity
l Molecular sieves are suited very well to take water vapor from air or gas with low relative humidity.
l Although Activated Alumina has a lower capacity than the other two, at lower humidities, it is quite satisfactory at the higher humidities. Activated Alumina is usually the most widely used desiccant

Detailed supply scope of IR 115RC Refrigerated Dryer:
Compressor, Pre-cooler/re-heater, Condensate, Evaporator, Expansion valve, Constant pressure valve, Automatic drain valve, Control panel
l High Efficiency Heat Exchange - IR dryers use state of art, high efficiency extended surface heat exchangers. This design minimizes pressure drops whilst maximizing thermal productivity, thus optimizing the dryer performance under adverse operating conditions.
l Moisture Separator with Integral Automatic Drains - IR Dryers use a multi-action moisture separator to ensure water is separated from the compressed air stream, after the evaporator. Optimum efficiency is gained with the use of large flow, solenoid operated drain valves.
This ensures that you get Dry Air for your process requirements.
l Hot Gas By-pass Valve - The key to constant Dew point control is the Hot Gas by pass valve. IR dryers use the finest valve of the world. The use of this valve in the refrigeration system ensures that your IR dryers will provide you with a constant low Dew Point, resulting in Dry Air.
l Filter - IR Dryers are fitted with a high efficiency Filter . This ensures that the refrigeration system will always remain clean and therefore offer the highest reliability.
l Sight Glass - IR Dryers are also fitted with a sight glass, to allow the quick identification of the refrigerant system.
l High and Low Refrigerant Cutout Switches - An IR Dryer has the perfect self-protection for its refrigerant compressor. A high-pressure cutout switch will shut down the dryer should the refrigerant head pressure become too high. A low-pressure cutout switch will shut down the dryer should the suction pressure become too low. This ensures that your IR Dryer can never freeze up.
