Barkell's varied and diverse range of Air Handling Units (AHUs) are developed to meet specific project requirements.

They are delivered in various case sizes with airflow from 0.2-50m³/s. The larger the flow rate required, the larger the case size, although Barkell can engineer the system to deliver maximum system output from the smallest possible footprint whilst still providing adequate space for maintenance.

Barkell's 'less-is-more' means that the most compact AHU will always be recommended given the required design parameters. This makes them ideal for indoor installation (internal installation) and for outdoor applications (external installation) where space is tight and of paramount importance.

AHU unit configurations

AHUs can be provided in indoor or outdoor, side-by-side or stacked, roof- or floor-mounted configurations. When specified at initial tender, Barkell can adapt and develop the AHU accordingly.

AHUs with complete flexibility

A choice of configurations is offered to give real operating flexibility to suit different applications and operator preference throughout all of our air handling units.

The Enviropack™ R410A refrigeration package is available throughout all Barkell's air handling units, providing the option for cooling (10-235kW) and heating (9-218kW). Available in single and dual circuits, Enviropack™ delivers up to 4 stages of cooling or heating across multiple skid platforms. A single control panel manages both the refrigeration package and the AHU.
