Halton HME can be used for air distribution and sound attenuation in various applications such as suites and pantries.
Halton HME can be used for air distribution and sound attenuation in various applications such as suites and pantries. The unit operates as a plenum box with a balancing and measurement module inside but also fulfils fire safety requirements as standard cabin unit. The supply volume flow rate is determined during commissioning by using the measurement and adjustment device. The airflow measurement tubes and control spindle can be accessed through the unit’s outlet. Using the pressure difference readings between the measurement taps and the k coefficient, the corresponding volume flow rate can be calculated. Rotating the control spindle adjusts the volume flow rate until the desired setting is achieved.

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 HME 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).

Correct airflow for HME unit is set during commissioning by adjusting MSM/MEM device in inlet spigot. MSM/MEM is operated by flexible spindle which is easy to access from outlet.
When passenger demands for warmer temperature by using contol 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.

Projects requirements and possibilities should be taken into account when designing the installation. For more information on the possibilities contact Halton Marine sales office.
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 install, draw it through the provided tube from Cabin unit to CP unit (the plug on CP unit is small enough to allow drawing through Ø 16 mm tubes). Max. allowed tractive force is 30 N. 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. Airflow measurement accuracy cannot be guaranteed if safety distance is not taken into account.
The supply flow rate is determined by using the measurement and adjustment module MSM.
The tubes and control spindle 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)

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.
Replace the tubes and spindle into the plenum.
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.
