Halton HML is an airflow unit for large air volumes with centralized airflow heating. The unit can be controlled with one control panel. HML VAV/CAV unit offers several regulation options from independent operation system to network applications. This pressure independent product can be equipped with reheater(s) from 900 W up to 30 KW.
Note: HML units are manufactured for rectangular ducts (width B 200-1000 mm and height H 200 – 1000 mm). Circular connection pieces are available. Non-standard dimensions and flange drilling available on request.
|Casing||Hot galvanized steel or EN 1.4404 (AISI316L) as an option|
|Insulation||Mineral wool, s = 50 mm, MED approved|
|Reheat coil||Incoloy 800|
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.
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.
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.

Note: When comparing airflow measurements between airflow unit and other device, unit’s airflow regulation dead-band has to be taken into account (± 10%).
