Improve indoor air quality and distribution

Hitachi airside solutions include modular air handling units that can be configured for different indoor air quality requirements, plus a range of efficient fan coils to quickly heat or cool spaces of different sizes.

Fan coils use a fan to blow air over integrated water coils which are connected to a chiller, and can be used for cooling and heating (with a compatible Chiller that supports heating operation). Hitachi fan coil units come in a variety of sizes and formats including cassette, ducted, ceiling suspended and wall mounted.

Air Handling Units come in a wide variety of sizes with different modules to enable air treatment and purification. They are normally connected to ductwork to distribute the treated air around a building.

Ceiling Concealed Fan Coil Units

Ceiling Concealed have an ultra-thin structure to meet almost any space limitation with unit height starting from just 243mm. Multiple ESP (external static pressure) choices: 12pa, 30pa, 50pa and a choice of capacities from 2.43-14.34kW (cooling) and 3.95-22.91kW (heating with air volume ranging from 340m3/h to 2380m3/h. Both 2-pipe and 4-pipe models available; a Hitachi reversible chiller with 2-pipe fan coil units are a cost-efficient solution for seasonal cooling and heating, while for simultaneous cooling and heating in mid-season or larger, well-insulated buildings, 4-pipe systems are recommended.

In such cases, a Hitachi chiller and boiler or multiple Hitachi reversible chillers with 4-pipe fan coil units are advised. The air return box comes with a heat recovery function that allows for the recovery of indoor return air, resulting in reduced energy consumption.
