Trident''s condensate sensing type automatic drain valves is the latest advancement in drain valve technology. Instead of operating through cycle timer, these valves sense the condensate level for activation, ensuring absolutely NO LOSS of compressed air and hence enormous ENERGY SAVING Trident condensate sensing type drain valves are highly efficient and reliable. These drain valves can be fitted directly on the equipment simply by replacing the manual drains.


Features:

  • Latest in drain valve technology.
  • Electronically senses condensate and activates valve.
  • No air loss and is extremely economical to operate.
  • Status indicator.
  • IP 65 protection.
  • Test button for quick check.
  • No noise as air is not discharged.
  • Capable of draining oily condensate.

Operations:
Condensate collects in the drain valve and the level slowly rises which is detected by the sensor. When the condensate reaches upper level the controller signals the valve to open. The condensate now drains. When the condensate level reaches low level the controller switches off valve and stops the draining.

 

The controller routinely checks for health of the system and can detect probe or valve failure and take action. There are 3 LED displays which indicate all these. There is also Test/ Manual override button. The condensate level sensor is of capacitance type. This makes it work on all types of condensates e.g. water, water+oil, water+oil+dust etc.

 

If the condensate is not discharged due to valve failure then the condensate level will not reach lower limit. The controller energises the solenoid coil for 8 secs. and waits for 2 mins. It repeats the timed cycle of 8 secs. ON and 2 mins. OFF, 4 times. If condensate level does not reach the low limit then the controller activates the alarm mode and alarm mode LED glows. In the alarm mode the controller works on a timed cycle. The controller automatically reverts to normal mode when the problem clears.


Application:

Trident condensate sensing drain valves are suitable for all compressed air systems like :

  • Air receivers
  • Separators
  • Air dryers
  • Filters
  • Inter and after coolers.

Dryer TechnologyDessicant
Automation GradeAutomatic
Voltage210-230 V
Body MaterialMild Steel
Surface TreatmentColor Coated

  • Designed for locomotive use
  • Non volatile memory system
  • Automatic Purge control valve
  • Fixed Volume Automatic Drain valve

Features:
  • Designed for locomotive use : Meets all Environmental and functional specifications for the Railroad industry. This dryer will withstand the vibrations, temperature in a locomotive platform out side the locomotive.
  • Operates over a wide Voltage range.
  • Non volatile memory system - The dryer is completely switched off when the compressor is off and restarts where the cycle was stopped. This increases the life of the dryer.
  • Automatic Purge control valve : Adjusts purge air depending on the compressed air flow and pressure. This ensures guaranteed dew point at optimized purge loss. This also reduces compressor usage.
  • Fixed Volume Automatic Drain valve drains condensate without wasting much of compressed air. It has a fail safe design.
  • Optimised design to meet Input-output dewpoint depression requirement.
  • Desiccant health indicator for each desiccant tower.
  • Pre-filter health indicator.
  • Low MTTR
  • High MTBF
  • All aluminum construction for corrosion free long life.
  • Slide-In mount : The dryer can be slided in and out for service and installation in minutes, when installed in the mounting bracket (e.g. Trident MB1).
  • Small size
  • Dewpoint depression of 30oC at design airflow and 15oC at worst case of airflow and ambient temperature.
  • Low pressure drop of 3% of inlet pressure at design air flow.

Operations:

Moist Air from the compressor enters into the Pre filter through the top manifold. Water and oil coalesces here. The condensate with water and oil is drained by the Drain valve. The drain valve is periodically opened by the controller. The specially designed drain valve discharges only a fixed volume of condensate and minimizes air loss. The air then passes through the Inlet Shuttle valve and the Drying tower. In the drying tower, Activated Alumina adsorbs the water vapour present in the air and sends out Dry air of required Dew point. Fine Alumina powder which may come from the bed of desiccant is removed by the After filter. Clean and dry compressed air is let out through the outlet shuttle valve and Purge Control valve.

 

The Purge Control Valve Diaphragm senses the outlet flow and accordingly the Purge Air port size area is varied. This varies the amount of Purge Air during regeneration in proportion to the flow of compressed air through the dryer. It is also a function of the inlet pressure and hence only uses purge air in proportion to the moisture load.

 

The two towers operate alternately in the drying and regeneration phases. In the regeneration phase dry purge air is passed through the tower under regeneration and released into the atmosphere. Under given operating conditions (service pressure of 10.5 Kg/cm2 (g)) 10% of the airflow is used for regeneration. A fixed quanity of air is purged during very low flows. The regeneration phase is shorter than the drying phase in order to allow the regenerated tower to return to service pressure before a new cycle starts. The purge is 10% for units with Auto Adjust purge control valve and fixed 15%without Auto Adjust purge control valve.


Application: Trident Locomotive dryers are designed exclusively for the railroad industry for the following applications :

  • Electric Locomotives
  • Diesel Locomotives
  • Commuter Locomotives
  • Shunting Locomotives
  • Mining applications

Product Details:

Dryer Horse Power5 HP
Minimum Output Dew Point-40 C
Drying Capacity501 - 1000 cfm
Pressures4 kg/cm2(g) to 70 kg/cm2(g) and flow upto 1920 m3/hr

Designed and tested to provide 100% clean, dry, oil-free compressed air at -40°c atmospheric dew point, to safeguard your valuable pneumatic equipment. Trident Dryers are available in 19 models to suit your requirement. 


Features:

  • Purge economizer, an energy saving device reduces purge loss to as low as 50%.
  • Programmable Controller, with clear functional displays, ensures uninterrupted operation even while tower changeover.
  • Automatic drain valves in pre and oil filter to reduce moisture load and to ensure life of desiccant at no extra cost.
  • All new Microprocessor based controller has a unique purge economizer. The dryer load can be manually set. It can also accept up to 3 compressor load/unload contact and compute dryer load dynamically. The purge is set accordingly. The controller also accepts a pressure input and purge air is controlled accordingly. 
 
Prefilteration: The moisture laden compressed air passes through the pre filter. Here moisture load is reduced through coalesence. Condensation is removed through the drain valve ADV1. At the oil filter (2) oil vapors are removed completely, small levels of oil/water condensation are purged through the valve ADV2. Compressed air is then passed through a 3 way valve into Tower.

Drying:
The Towers are filled with Activated Alumina as desiccant (Molecular sieve available as option). When air passes through Tower 1 which consists of "DRY" Dessicant, it gets completely dried, and passes through check valve and After Filter(3). At the after filter, Desiccant fines are removed. Therefore dry compressed air passes out at the outlet.

Regeneration:
Regeneration takes place in 2 stages a) De-pressurisation b) By passing Dry air. Tower II consists of fully moist desiccant at pressure. This is suddenly De-pressurised by opening the purge valve. Water molecules weep out of the desiccant and appear on the surface. "Super Dry" purge air passes through the Regeneration "Nozzle" and the desiccant bed thereby completely carrying away the water molecules. Tower 2 gets regenerated and is ready for the next drying cycle.
