Specification

Halton HFR/M is pressure independent or pressure dependent single duct cabin unit with 1-3 outlet connections for terminal units. Pressure independent VAV or CAV operation is facilitated by continuous airflow measurement and damper regulation by intelligent controller. Pressure independent HMF adapts to variations in supply ductwork pressure levels and maintains individual fresh supply airflow rate to each cabin. Pressure dependent VAV operation is facilitated only by damper regulation by intelligent controller. Pressure dependent HMF adapts to room temperature changes by regulating airflow between pre-set minimum and maximum damper positions. Halton HFR/M is an excellent choice for suites, deluxe cabins and office areas where the total airflow needs to be distributed to several points, but controlled centrally with one control panel.

Accessories

MS-Cable (master-slave cable)

  • For master cabin unit – slave cabin unit/units connection
  • Prefabricated with plugs on both sides
  • Halogen free and flame-retardant
  • Standard length is 7 meters. Other lengths available as an option.

Communication adapter

  • Bluetooth communication to external device
  • For wireless connection to set cabin unit parameters and trouble shooting

Network adapters

  • Network adapter (also available as WiFi) expands a stand-alone unit to network compatible unit (LON or Ethernet network)
  • Enables supervision and advanced energy efficiency functions
  • For more information, see Halton Networks for cabin ventilation -brochure or contact Halton Marine Sales office.

Reheaters available

  • Standard reheaters: 400W, 800W, 400+800W, 1200W, 1500W, 1800W
  • Offshore reheaters: 400W, 800W, 1200W, 1600W (surface temperature below 90ºC on operating airflow)

Practical power level may be software adjusted cabin by cabin. Cable and power supply design has to be done according to maximum available heating power.

Function

Control panel includes also a number of special features such as diagnostics function, room brightness measurement and re-programmability. The power supply and data transfer between cabin unit and control panel is carried out via interconnection cable.Temperature range is software adjustable between 10 and 30°C.

Function of VAV unit

When passenger demands lower temperature by using control panel unit, the damper opens in order to increase the flow of cold air towards the maximum value. When the required temperature in the cabin is achieved, the damper reference is held until the temperature demand changes. In heating mode, the damper restricts the airflow towards its minimum rate, and if the required temperature in the cabin is not thus achieved, the controller activates the electric reheater inside the unit in a stepless manner.

Function of CAV unit

Airflow is kept in pre-set level in any condition. When passenger demands for a higher temperature by using control panel, the electric reheater inside the cabin unit will be activated in a stepless manner towards to maximum heating capacity or until desired temperature is achieved. When passenger demands for a lower temperature by using control panel, the electric reheater inside the unit will be deactivated in a stepless manner towards to zero heating capacity or until desired temperature is achieved.
