The dynamic style of HITZINGER pre-conditioned air units reflects innovation and technical know-how. The flexible layout allows customized PCA solutions and an integration of hot or cold water chilled coils. The AIR POWER can either be mounted on a passenger boarding bridge or stationary below. For more flexibility, our PCA unit is also available as mobile towable version.

The combination of an aluminium light-weight construction and the use of energy efficient components support our general understanding of reduction of total costs of ownership. Our modular concept allows an easy installation, quick accessibility for maintenance purposes and reduced inventory of spare parts.
