Introduction
The document provides technical details about the Split Flow Air Dryer, specifically the Heated Desiccant Dryer - DS series, designed for onshore and offshore applications. It highlights the product's capability to achieve a dew point better than -40°C and its status as India's largest exporter of compressed air treatment products.

Specifications
The DS series includes models DS 500 to DS 4000, with inlet flow capacities ranging from 500 to 4000 cfm. Each model specifies the connection size and heater power required. The dryers are designed for an air inlet pressure of 7 kg/cm², an air inlet temperature of 38°C, and an ambient temperature of 35°C. The desiccant used is activated alumina with a 14% adsorption capacity.

Principle of Operation
The Split Flow Dryer operates on the principle of Thermal Swing. It uses a heater to regenerate the desiccant bed by heating split hot air, avoiding purge loss. The process involves splitting the inlet air, using a portion for regeneration, and then recombining it before adsorption. This method ensures no purge loss and effective moisture adsorption.

Working Principle
The dryer avoids purge loss by splitting the inlet air and using it for regeneration. The heated air carries moisture from the desiccant and is cooled before being mixed with the inlet air for drying. The system ensures the heated bed is cooled using dry air to prevent dew point spikes. The cycle involves changing valve positions to shift the regeneration process between towers.

Salient Features
The dryer offers no purge loss, low dew point, low pressure drop, and low energy cost. It is compact, ready to use, and reliable, with dew point-based tower changeover controls and low total cost of ownership.

Additional Products
The company also offers timer-based and level-sensing auto drain valves, submicron filters, moisture separators, and both heated and heatless desiccant dryers.

Manufacturing and Presence
Trident Pneumatics Pvt Ltd has manufacturing facilities in India, China, and Malaysia, with sales and service outlets across major Indian cities.

Local and Central Control Interfaces
The local panel interface includes flow indication, alarms for low flow and heater failure, emergency stop, and system status indicators. The central control room interface provides heater failure alerts, run/trip status, and optional high moisture level alarms.

Applications
The document does not specify applications, but the features suggest suitability for various industrial air treatment needs.
