Halton HMM is a manually operated cabin unit for single duct applications.
Halton HMM is a manually operated cabin unit for single duct applications. Airflow is controlled via an adjusting knob installed on the diffuser. The control mechanism has mechanical limits for minimum and maximum airflows. These limits can be easily set during commissioning. HMM is recommended to be used in conjunction with Halton’s diffusers, as the mechanism has to be fixed to the diffuser’s structure. The airflow is adjusted with diffuser knob. The HMM cabin unit can be supplied with reheater – controlled by a control panel.

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.
Halton Marine HMM cabin units are available with three different control panel models; with rotating knob, push buttons with LED bar graph (available as option: IP54) and push buttons with LCD-display (available as option: IP54).

Please note: HMM and HME units are also available without a control package.

Airflow is controlled via an adjustment knob between the preset limits.
When passenger demands for warmer temperature by using control panel, the controller activates the electric reheater inside the cabin unit. When the required temperature in the cabin is achieved, the reference is held until the temperature demand changes.
Mechanical maximum and minimum limits are set during commissioning.

Projects requirements and possibilities should be taken into account when designing the installation. For more information on the possibilities contact Halton Marine.
The LRC-1 CP unit should be positioned on the wall inside the room it will regulate. It is advised to avoid direct sunlight or position near heating/cooling source object
Interconnection cable comes prefabricated with plugs on both sides. To ins tall, draw it through the provided tube from Cabin unit to CP unit (the plug on CP unit is small enough to allow drawing through Φ16mm tubes). Max. allowed tractive force is 30N. On the CP side, in the room, leave approximately 8 cm of the cable (the wires) outside the tube. The near end of the tube (CP-unit side) must be blocked (e.g. foam) to prevent condensation and thermal transfers reaching CP unit.
A required safety distance as illustrated must be taken into account when installing the cabin unit.
The supply flow rate is determined by using the measurement probes and manometer.
The diffuser front plate are removed and tubes are passed through the diffuser. Measure the differential pressure with a manometer. The flow rate is calculated using the formula below.
qv = airflow (m3/h)
k = k factor
∆pM = measured pressure (Pa)
HMM | k |
HMM-100 | 48.2 |
HMM-125 | 74.2 |
Adjust the minimum airflow rate by rotating the D-shape bar until the desired setting is achieved.
Move the minimum airflow mechanical limiter against the stand and tighten socket cap screw.
Adjust the maximum airflow rate by rotating the D-shape bar until desired setting is achieved.
Move the maximum airflow mechanical limiter against the stand and tighten socket cap screw.
All parameters can be preset at the factory according to order. During commissioning all parameters can be modified wirelessly with a PDA handheld device using LRC manager software.
Halton also provides supervision and commissioning services for the projects.
