General Description

The Nortec EL steam humidifier is an advanced electrode steam humidifier with state-of-the-art features.

built-on blower pack. The large models, with steam capacity from 150 lb/h (68 kg/h) to 200 lb/h (91 kg/h),
are equipped with dual steam cylinders – each with its own dedicated driver board.
The dedicated driver boards in the large models allow the steam cylinders to be configured to operate in
series, in parallel or independent mode. Two separate sets of control signals are needed for independ-
ent mode of operation. In series mode, the output capacity of steam cylinder "A" is configured to 0-50%
of humidifier demand, and steam cylinder "B" to 50-100% of humidifier demand. In parallel mode, the
output capacity of each steam cylinder is configured to 0-100% of humidifier demand.
In addition, up to six integrated controllers (for a maximum of 12 steam cylinders) can be set up in a
"main-extension" configuration using Nortec's Linkup system to satisfy large humidification needs.
