Products - Air-handling units of series H/HL
Product Characteristic
Air-handling and air-conditioning units of series H/HL are modular square or rectangulared units designed for central distribution and air treatment, i.e. for filtration, heating, cooling, heat recovery, humidification and dehumidification in production facilities, office buildings, hospitals, shopping centres, schools, sports facilities, restaurants, food processing facilities and other premises.
Output and Size Specifications
Type sizes of the units are in accordance with CSN 127001.
Rated volume air flows are defined as the optimum ones with respect to the optimum energy consumption, efficiency and noise characteristics of the units. The units HL2 size – HL4 size for suspension under-ceiling.

The protective zinc layer on the panel sheet is 275 g/m2 at minimum. In case of special demand it is possible to supply units with panels made from painted sheets or from stainless sheets. Doors are made from modified panels and are fitted with hinges and locks.
The fan-motor set with V-belt drive is mounted on the common frame, which is made from special profiled Al-bars. The set is spring-mounted on the section structure by means of rubber blocks. The fan discharge and section wall are interconnected with flexible insert. The suction and discharge openings of the unit are fitted with flexible insert for connection to a pipeline.
