Trident offers innovative and customised solutions catering to specialised application requirements of varied industries and thereby, ensure the availability of quality air and gas for all applications.

Oxygen Generator


Oxygen is the most important clinical gas used in health care centers and Hospitals. No modern hospital can manage without oxygen gas Generator. Pure oxygen is an essential resource in the operating room during anesthesia, for the respiration of patients, and in the intensive care or neonatal units. The constant high demand for this gas renders substantial expenses for hospitals. Currently, hospitals buy oxygen from bulk medical oxygen plant Manufactures. The bulk oxygen is bought in both liquid and gaseous form. These sources of oxygen can become an economic burden as large hospitals can spend more money in a year on oxygen supply alone.

Fortunately, Medical oxygen can be generated on-site in any hospital, clinic, or health care center in a much more cost effective manner. Using pressure swing adsorption method oxygen is generated and it is being used, thus enabling a health care center to be self-sufficient in meeting its oxygen demand.

PSA methods are capable of producing oxygen in medium capacity. This is ideal for an on-site hospital unit, because it is a safe process with reasonable energy and area requirements. And acceptable as per USP and Global standards. (Read Catalouge for detailed Principle and Details).The oxygen plant manufacturers in India by Trident, provides bulk oxygen cylinder to the hospital for medical use which is cost-effective and also most reliable.

Air Dryers


An ideal solution for clean and compressed dry air is provided by Trident , one of the experts among the Refrigerated air dryer Manufacturers. Extensive design strategies and prototype testing culminates in Trident’s amazing products that offer a constant dew point of +3 degree Celsius. Also, the CS series of Trident offers a very low running cost unlike the other air dryers.

The cold dry compressed air passes back through the secondary side of the Air to Air heat exchanger where it is reheated by the incoming warm air. Reheating the outgoing compressed air increases the volume of the air enabling it to do more work and it also prevents downstream pipe sweating. Trident heat exchanger has no extended surfaces or sharp corners that collect dust, dirt or oil residue. Their self cleaning smooth surface tube in shell and tube design will maintain the same heat transfer efficiency through out the dryer's life. Any dust, dirt or oil will be washed off from the air system along with the condensed moisture at the De-mister.

Some of the key features are

  • Maintaining of a consistent pressure dew point
  • Control of the condensing temperature for atmospheric variations in temperature
  • The safety of compressor provided by the HP cut switch
  • The advanced mimic display that indicates the functions and faults if any
  • The provision of Trident automatic drain valve in Demister and Heat exchangers for efficient dryer functioning.


Trident pneumatics are perfect examples of vast knowledge, rich experience, meticulous engineering and skilled compressor air dryer manufacturer, which enable it to develop dryers with highest quality performance. The Dryspell Plus series launched successfully by Trident in the Indian and overseas market is a proof of guarantee, warranty and reliability. These dryers are also very economical, manufactured in large quantities, designed and tested to provide 100% clean dry oil free compressed air and require no maintenance in comparison to the refrigeration dryers of it’s range. The Dryspell plus is an ultimate compact dryer with valves and piping built into the manifold. These dryers are suitable not only for point of use but also are available for 10, 20, 30, 45, 60, 100, 125,200, 250, 300, 375 scfm. Paint shops, instrumentation, hand tools, powder coating, CNC machines, automobile garages, dental equipment, pharma are some areas where these dryers are applied extensively

Some of the key features are

  • Provides manifold construction
  • Provides a shuttle valve for low pressure drop that is controlled by the microprocessor
  • Equipped with a built in microprocessor based controller
  • Equipped with a pre filter that has a borosilicate glass fibre element
  • The pre filter drain valve is not only timer based but also gets activated by the controller


  • They save energy besides economising purge by reducing the loss of purge to a minimum of 50%.
  • They have controllers with lucid functional displays that are programmable.
  • They secure undisturbed operation despite tower changeovers.
  • The moisture load is lessened by the auto drain valves in pre and oil filters. Therefore the desiccant life is secured without any extra cost.
  • The inclusion of a unique purge economizer in the latest microprocessor based controller which facilitates manual setting up of the dryer load. This device can not only accept upto 3 compressor load/unload contacts but also compute the dryer load dynamically. According to these settings done, the purge can be set. Also, the purge air can be controlled according to the pressure input accepted by the controller.

Drain Valves


The EDV/CTD valve series represents the ultimate in valve performance. Decades of experience of valve manufacturing have allowed us to identify the issues commonly associated with drain valves and undertake the necessary improvements required. Today the EDV/CTD valve incorporates an ultra-reliable MCU, which features dual control of both drain cycle and drain valve open-time. The oversized orifice design and a specifically designed solenoid operator section allow rapid discharge of dust and particles.


The drain is controlled by a timer. The timer module periodically activates the valve. The valves are designed for dirty liquid and handle all types of condensate. These direct acting models have 2.5 mm orifice. The timer has adjustments for both Drain and cycle time. Further there is manual flush button to drain excess condensation if required.
