With many years experience making market leading compressed air dryers, Norgren's team of experienced engineers have applied their knowledge and experience into eliminating many of the problems associated with desiccant dryers.
The Norgren Hydra-D range is a new standard for compressed air dryers incorporating innovative features and benefits. Compressed air is an important source of energy that is widely used throughout industry. Certain processes have an essential requirement for clean dry air to ensure their safe, efficient and profitable operation. The problem with air is that it contains water vapour, which condenses to water droplets when the air cools. Water and dirt in compressed air is a major problem as it may damage the equipment being supplied by the compressor and contaminate the process that equipment supplies.
Patented filter/desiccant cartridge - water separation, inlet and outlet filtration and desiccant integrated into a single cartridge (can eliminate up to 3 external filters) improving flow distribution giving better performance and lowering pressure drop. High density filled desiccant provides maximum adsorption capacity and the easy to replace cartridges simplifies and speeds up maintenance.
PLC controlled operation - The dryer is controlled by a robust and reliable plc control system. The PLC memory retention enables the controller to resume the drying cycle at the point where it previously stopped, ensuring clean and dry air downstream.
Energy saving dew point control option - Monitoring of outlet dew point means purge only occurs when the bed is fully saturated, saving on purge air.
Optimum dewpoint performance - Air velocity is controlled by a pressure maintaining device to ensure dew point maintenance constant flow and pressure.
Constant flow and pressure - Pressure is equalised before switching columns to ensure consistent air pressure and to reduce movement of the desiccant media which causes attrition.
Reliable high performance valves - Hydra-D1 uses ball valves and two piloted solenoid valves and hydra-d2 and d3 series use four piloted solenoid valves to control inlet and outlet air, maintaining air pressure within the dryer which prevents ingress of moisture onto the desiccant beds when off-line.
Floor or wall installation - can be floor or wall mounted – simply by rotating the mounting feet by 90°.
Quiet operation - optimising the exhaust air flow paths result in reduced noise levels.
Strong corrosion resistant construction - Anodised, high tensile extruded aluminium.
