DRYER HRE-4000

PRODUCT DESCRIPTION

The externally heat regenerated adsorption dryers HRE tropical 0375-13600 work according to the dynamic adsorption principle. Wet compressed air streams through a desiccant bed. While streaming through, moisture is drawn out of the compressed air. Since the adsorption capacity of the desiccant is limited, the flow direction has to be changed be- fore the desiccant is completey saturated. Using two parallel adsorption vessels (adsorbers AD1 + AD2) with alternating function, the permanent supply of dried air for consumers is guaranteed.

One adsorber is always available for drying the compressed air. The second adsorber is regenerated at the same time. The activation time respectively the regeneration time is always shorter than the loading time of the working adsorber.The regeneration of the saturated desiccant is realized in two steps:

1. Desorption in counter-current flow to the adsorption direction with externally heated blower air

2. Cooling of the heated desiccant with a partial stream of dried compressed air

Typical applications for the adsorption dryers HRE tropical are:

• Central compressed air purification
  Generation of dry, oil-free and particulate-free compressed air (with option pre- and after filter)
• Point-of-use applications
  Drying and purifi cation of control and instrument and process air
• Automotive industry
  Purification of compressed air for painting applications

MAIN FEATURES & BENEFITS

• 19 sizes available, matching to the compressor flow capacities
• Energy efficient regeneration (desorption) in counter-current flow
• Excellent for application in tropical environment, cooling of the desiccant by partial current flow of the dry air
• Inlet temperatures up to 45°C permitted
• Pressure dewpoint of -40°C as standard
• Robust design with welded steel vessels and flanged pipelines
• Service-friendly design of butterfl y valves and pressure reducing valves for fast replacement of wearing parts
• Robust, efficient programmable controller of the latest generation, for which service and support are guaranteed beyond the next decade
• Touch Panel with a high operational comfort; The main menu shows a system overview with the operational data such as pressure, temperature, cycle of the vessels etc.
• Comprehensive option package: dewpoint dependent capacity control, start-up-device, free of silicone and parting agents, bypass line, filter extension etc.
• Suitable high efficiency filters as pre- and after filter (option) ensure a low differential pressure for the complete unit and thus small operating costs
