Description
The heated blower desiccant dryers HBA series guarantees dry air at -40°C, without any consumption of compressed air. This technology uses an innovative blower which draws ambient air, which is subsequently warmed up by a heater and sent to the column to regenerate the adsorbent material. Then, the reverse blower produces a counter airflow to effectively cool down the desiccant media inside the column. This technology allows to reduce to zero the air consumption related to the cooling sweep.
Heated blower dryers requires a greatest initial capital investment and a greater expense for electricity, but it guarantees a complete reduction in the consumption of compressed air, which in many applications makes it more competitive with respect to heatless technology.
