The heated dryers deliver a constant -40°F to -100°F (-40°C to -70°C) pressure dew point for critical applications Externally Heated Capacity Range: 400-2100 cfm (11.3-59.5 m3/min) Pressure Dew Point: -40°F to -100°F (-40°C to -70°C) ISO Class 1 to 2 Voltage: 460V/3PH/60HZ (400V/3PH/50HZ) Maximum Inlet Pressure: 150 psig (10.3 barg) Maximum Inlet Temperature: 122°F (50°C) Desiccant Type: Activated alumina Features: Low profile design for ease of service Low pressure drop design Pre-filter and after-filter as standard Easy to use, advanced microprocessor High performance valves for long extended life Heated these dryers operate similarly to heatless dryers, with a big exception. Dried air diverted from the air system is first passed through a high efficiency external heater before entering the off-line tank to regenerate the desiccant. Since this heated air can hold considerably more moisture than unheated air, only about half the amount of dried compressed air is needed for regeneration. . Although the addition of the heater and associated components raises the initial capital investment for a heated dryer, less diverted compressed air means lower operating costs.
