“The only humidity analyzer available that meets or exceeds the performance of lab
technology, whiles being able to sample at the most challenging positions in our
Humidity is one of the most important parameters which can be used in maximizing the efficiency of spray drying operations.
Measurement of absolute humidity at elevated temperatures and high dust loads – in an accurate and reliable way – has
always been a challenge for end-users. RH Capacitive and dew point measurement technology has proven to be inaccurate
and unreliable for these challenging applications. In addition, soft sensors (material balance, flow, density) calculation
of H2O depends on too many parameters and is often considered to be imprecise.
With our proprietary probes, the HICOSYS AQUA is capable of measurement at the most challenging locations such as the
tower exhaust, even before filtration by cyclones and/or bag filters.
The TDL (tunable diode laser) based HICOSYS AQUA, sequentially measures both sample streams. The operator receives continuous
information and updates of the H2O concentrations of the two sample streams, given in vol.% or g/kg dry air. The proprietary lowpressure
sampling concept avoids condensation of water whiles making sample tracing obsolete.
