When gas containing water vapour passes through Nafion tubing, the water is absorbed by and moves through the walls of the tubing, evaporating into the surrounding air in a process called per-evaporation. The remaining components in the gas are unaffected. The reaction is driven by humidity gradient until equilibrium is reached. If a dry purge gas flows over the exterior surface of the Nafion tubing, water vapour will be continuously extracted from the gas stream inside the tubing until the sample humidity matches that of the purge gas.

• MD series contains a single Nafion tube
• PD series contains a bundle of Nafion tube
• DM series dryer used for portable applications

• They are ideal for low-flow, compressed air drying applications

• Dryer operation is fully automatic, with outlet dew points as low as 50°C
  
  

FC - series

• They use an exclusive Nafion membrane tubing to continuously humidify gas streams
• These humidifiers operate over a wide range of flow rates
  
• They can use either liquid water or a humid gas stream as a source of humidity

The water-to-gas humidifiers:

• They have water on one side of the tube wall and the gas to be humidified on the other
• These humidifiers offer the greatest amount of humidification

The gas-to-gas humidifiers:

• They use counter-flowing arrangement to move water from one stream to other
• They can be used as heat exchangers as well

ME - series moisture exchanger:

• It uses Nafion membrane tubing technology to transfer water to or from gas.
• It is ideal for both drying as well as humidifying gas streams

MH & PH - series humidifiers :

• They use permeation distillation as the operating principle
• As only water molecules are transferred bacterial growth and contamination will not occur

• They are high-efficiency particulate and coalescing filters
• They are designed for high-temperature, corrosive service
  
  

• They are inertial separation filters for high participate load applications
  

• Used in the upstream of fine paniculate FB-series filters will greatly increase the life and performance of paniculate and coalescing filters
  

• They produce purified air at rates up to 18 liters per minute with just a flip of a switch

• They convert ambient air into clean air that meets the norms of zero air for instrument calibration

  
  
  

• They remove ammonia from a gas stream
  

• They protect analysers and sample lines from clogging due to the
  formation of ammonium salts

  
  
  

• ED-series eductors or aspirators are non-mechanical pumps

• They exploit the Venturi effect to draw a liquid or a gas into a flowing stream

• They can serve where corrosion-free or maintenance-free operation is of particular concern
  

• Premapure’s unique sample conditioning technology assures that a cleaner, dryer gas is delivered for the most accurate analysis. Innovative probes, line filters, scrubbers dryers and controls work together in a complete package to achieve quality sample conditioning
