1765cfm blower purge desiccant compressed air dryer with independent dew point control
Flow rate: 3000Nm3/h
Presssure dew point: -40 to - 70 deg c
Type : blower heated
BR 400-20000 adsorption dryers are designed for continuous separation of water vapour from compressed air thus reducing dew point. Operation of dryer requires two columns operated alternately. Adsorption takes place under pressure in first column while second column regenerates with a heated ambient air or purge.
A dryer consists of two columns, filled with desiccant beads, blower, heater, controller with LCD dicplay, valves, manometers, and support construction. Proven robust design enables efficient and reliable operation, fast installation and simple maintenance.
HIGH QUALITY TWO LAYER DESICCANT BED
BR series adsorption dryers are filled with a high quality robust desiccant which results in stable operation with low energy input for regeneration. The primary desiccant is a silica gel with an extremely high drying potential.
To prevent potential degradation of the primary desiccant, due to liquid water, the bottom part of the column is filled with an additional layer of special water resistant silica gel. The advantages are
Stable pressure dew point down to -70 deg c
Low regeneration temperature with energy saving up to 33%
Extended desiccant service life
Energy saving dew point dependent control (DPD)
BR dryers are designed for “full load” at pre-determined operating conditions (flow, pressure, temperature).
However in reality “full load” is typically not present all the time meaning that the dryer is operating under partial load. In this case the adsorption cycle can be extended. If the BR dryer is equipped with dew point dependent sensor (available as optional equipment) it can detect when the load is reduced at witch point the controller automatically adjusts the cycles so that energy consumption is reduced to a minimum.
