Air handling unit – humidification

Introduction

Humidification graphic

Typical for applications are: nowadays preferred steam humidification (up to 140°C steam); fail-safe function is required; 0-10 V control signal; 2-port flanged or threaded valves; stainless steel trim; PN 16 pressure class.

The proposed combinations vary in: control accuracy; plant operating conditions.

Fast and accurate flow control combination

Fast and accurate flow control combination

PN 16 magnetic flanged valves with integrated actuator and selectable valve characteristic; fast and high-precision flow control for operation up to 180°C and steam pressure up to 9 bar; opening without inlet jump; excellent for minimum controllable load.
