HFR/M cabin unit is supplied with control panel and interconnection cable
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.

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.
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.
Regulation diagram, VAV
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.

Airflow measurement accuracy
* ductwork pressure 200-1000 Pa (optimal)
Note: When comparing airflow measurements between cabin unit and other device, cabin unit’s airflow regulation dead-band has to be taken into account (± 10 m3/h).
