Pioneers in Compressed Air Drying and Filtering. Quality at a Fair Price. 
Features and Benefits
  • Pipes – All pipes are expertly welded to ensure a non-leaking robust construction which offers little resistance to air flow.
  • Valves - Specifically designed shuttle valves require no lubrication and have low maintenance.
  • Vessels - All vessels are government certified to PD 5500:2015 standards and are supplied with certificates of compliance. ASME 8 as an option.
  • Pressure Gauges – All dryers are supplied with pressure gauges to enable the user to monitor the correct operation.
  • Electronic Enclosures – Enclosures for the electronic controllers are to IP52 standards allowing for safe user operation and protection of circuitry.
  • Display Panel – A LED display panel mimics the operation of the controller thereby indicating the current status of the electronically controlled purge and re-pressurisation valves.
  • Silencers – A unique range of silencers may be fitted which will reduce vessel purge noise down to 75 dba.
  • Operating Voltage – A choice of operating voltage is available according to the client’s requirements. All controllers have standard 220V 50 Hz operating voltage.
  • Technical Support – Tegnon offers an experienced team of maintenance personnel capable of delivering the highest level of service in the industry. Your problem becomes our priority.
  • Optional Service Contract - We also offer all our clients our TEGNON ULTRACARE service contract which will allow you complete peace of mind and accurate maintenance budgeting for your business.
Operation
  • The Tegnon RHL dryer consists of two separate adsorbent chambers. One chamber dries the air or gas while the other is being reactivated - providing a continuous drying operation.
  • The wet air or gas enters at the bottom of the left chamber and passes upwards through the adsorbent where it is dried to dewpoints as low as -70ºC.
  • The dry air passes through the outlet near the top of the left chamber. At the same time, a small amount of the exit air is expanded across a valve between the twin chambers. This purge air flows back through the adsorbent in the right chamber - reactivating it - passing out through the purge exhaust.
  • At the end of the cycle the process is automatically reversed with the right chamber doing the drying while the left is being reactivated.
  • The Tegnon RHL dryer unit can be put into operation and will allow flow even if adsorbent beds become inadvertently saturated.
