Various sizes available, so it adapts easily to the size of the air handling unit

Maximum efficiency

- Hydraulic unit installed in the AHU
- No loss of load
- No condensate in the distributor
- Helps heat the room

Germ-free steam

Isothermal humidification produces sterile steam
  • Installed directly in the AHU: no need for an electronics compartment or distribution piping
  • Automatic draining system with 40 mm diameter
  • Protects against flooding in the AHU
  • Mechanical parts designed to simplify use and maintenance
  • Stainless steel electrodes
  • Electrical panel separate from the hydraulic unit
  • Microprocessor controller with LED user interface
  • Connection for RS-485 protocol for remote control in MODBUS mode

The standout feature of the VEH series is that each model is made up of two separate units: a polypropylene hydraulic unit 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 IP55 protection which requires no electronics compartment.

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.
