Vertical Air Handling Unit

Vertical air handling equipment for plant rooms and floor-standing installations.

Overview

The vertical air handling unit is a floor-standing air-treatment assembly for plant rooms and other locations where an upright cabinet suits the available space. Its vertical arrangement brings the filter, water coil and fan sections together while leaving the connection layout to be coordinated with the duct network.

A centrifugal fan moves air through the selected filter and heat exchanger. Chilled water provides cooling and dehumidification, and an appropriate hot-water supply provides heating. The required coil rows and fan duty are selected against the actual design conditions.

The catalogue provides several vertical models and coil configurations. Final dimensions depend on the selected thermal duty and arrangement, so room height, access direction and the available space for servicing are considered before the layout is fixed.

PRODUCT DETAILS

Product Features

Upright floor-standing cabinet

The vertical form suits equipment areas with usable height and a limited plan arrangement. The cabinet position is coordinated with the building structure, pipe routing and duct connections.

Integrated air-treatment assembly

Filter, coil and fan sections form a central treatment path. This gives the designer one coordinated unit for the required air quantity and thermal duty.

Copper-tube water coil

The selected water coil exchanges heat between the building’s water circuit and the airstream. Catalogue coil arrangements allow duty to be reviewed for both conditioned-air and outdoor-air operation.

Centrifugal fan selection

The fan is chosen for the required airflow and the resistance of the downstream system. The pressure allowance includes filters, ducts, outlets and other selected accessories.

Insulation and drainage planning

An insulated cabinet and correctly arranged condensate disposal support cooling operation. A suitable drain trap, water-pipe insulation and protected connections form part of the installation.

Accessible inspection and cleaning

Filters and heat-transfer surfaces need periodic attention. The layout should leave practical access to the service side and avoid making the fan or coil inaccessible after the ductwork is installed.

The printed performance table covers vertical / horizontal arrangements; these references identify the vertical layout. A/C duty and all-fresh-air duty are different catalogue conditions. A dash in the 040L cooling cell indicates an ambiguous source value requiring confirmation. Confirm the complete model code, coil rows, water conditions and installation drawing.

WHERE IT WORKS

Applications

Suitable for commercial and industrial buildings using centralized chilled- or hot-water systems. The upright form is particularly relevant where an equipment room can accommodate the required cabinet height and floor loading.

Confirm airflow, pressure, water temperatures, cooling and heating duty, connection side and access space. The final unit dimensions follow the selected model and coil arrangement.
