The basic idea is an action technology which purifies N2 from 99.5-99.9% to 99.9999% (1ppm) only using 0.4kW per 1m3 of N2.
All versions made for feed nitrogen with 99,5 or 99,9% purity and will use 5 % of feed gas as scrubbing gas for the heated adsorbtion dryer, so if exists demand to 1.000 Nm3/h you need a feed gas of 1.050 Nm3/h.
OPAS comes in 7 different versions starting from 50 Nm3/h ending at 1.000 Nm3/h.
OPAS 100 capacity 50-100 Nm3/h
OPAS 200 capacity 100-200 Nm3/h
OPAS 300 capacity 200-300 Nm3/h
OPAS 400 capacity 300-400 Nm3/h
OPAS 500 capacity 400-500 Nm3/h
OPAS 750 capacity 500-750 Nm3/h
OPAS 1000 capacity 750-1.000 Nm3/h.
