Choose the most suitable version for your AHU
Models are available with 4 or 7 electrodes of different depths and steam production capacity that goes from 10 to 100 kg/h, making the VEH series easy to adapt to the size of the AHU.
A range of accessories is available to customise the size and accessibility of the hydraulic unit.
- Tank in self-extinguishing engineering plastic and in compliance with Method A and Method C of ISO 846
- Automatic draining system with 40 mm diameter
- Protects against flooding in the AHU
- Microprocessor controller with LED user interface
- Connection for RS-485 protocol for remote control in MODBUS mode
- Mechanical parts designed to simplify use and maintenance
Separate plumbing and control
The standout feature of the VEH series is that each model is made up of two separate units: a hydraulic unit in self-extinguishing engineering plastic which is ISO 846 certified (it is installed directly in the AHU, it has no distribution piping for optimal steam release and helps heat the room) and an electrical control unit with IP65 protection which requires no electronics compartment.
Positioning enhances efficiency
Placing VEH humidifiers inside air handling units means energy savings: not only does the 100 °C steam help with heating, it is also produced exactly where it is needed, preventing the formation of condensate and the loss of load due to back pressure, which can occur when steam is conveyed from its point of production to its place of distribution. And when AHUs are installed outdoors, placing the humidifier inside means no protective casing is needed for it.
