Variable speed management

Equipped with an EVCO inverter installed in the electrical compartment and physically separated from the hydraulic unit
  • Humidity distributed into an AHU or the room
  • Number of nozzles customisable (4 l/h or 8 l/h)
  • Constant 80 bar pressure irrespective of number of nozzles
  • Tiny particles produced (15 μm)
  • Stainless steel pumping system
  • EVCO controller with an EPcolor interface on the hydraulic unit and an EVCO controller with an EV3 interface on the distribution rack
  • Pump control with instant viewing of operational parameters

The humidifiers in the HPN series deliver steam into the room using a customisable distribution system, or directly into an AHU, using distribution racks with a configurable number of branches and nozzles. Several AHUs can be served by a single humidifier by connecting the hydraulic unit to multiple distribution racks. Each rack has its own controller connected to the AHU humidity sensor. Depending on the production requirement of each rack, the precision control of the hydraulic unit keeps the pressure of the fluid constant (8 MPa), producing mist with a particle size of around 15 μm, irrespective of the size of the rack.

Steam distribution racks

Distribution racks are available in three different heights; Distribution racks are available in three different heights; the length of the branches is variable and nozzle size may be 4 l/h or 8 l/h. The number of nozzles can be customised to the client’s needs. The EVCO controller installed on the rack gives proportional control of the opening of the nozzles. Built entirely in stainless steel, the distribution system automatically controls the solenoid valve to discharge water, meeting the hygiene requirements of VDI 6022-1.
