The market’s most innovative, smartest and environmentally friendly PCA unit for de-centralised use. The pre-conditioned air unit is available for mounting underneath the passenger boarding bridge, as an apron mounted unit or in a mobile version.

The ITW GSE 3400 PCA is innovative, reliable and environmentally friendly. It supplies fresh, clean air into parked aircraft at carefully monitored temperatures and provides a pleasant atmosphere for the crew and the passengers. It also makes aircraft turn-around faster and more effective. The point-of-use 3400 PCA is the market's only true modular PCA (patented). It is designed around identical cooling modules that can easily be swapped by a technician with no special skills and in 20 minutes only.

This smart and innovative PCA is available in the following models:

  • 130 kg/min
  • 210 kg/min.

Additional Notes

  • Specifications
  • Advantages


The increasing focus on environmental issues means that airports aim to let an external pre-conditioned air unit and a 400 Hz solid-state unit take over the functions of the aircraft APU while the aircraft is parked at the gate. We call this the “Go Green on Ground” concept whereby carbon emission is reduced by approx. 80-85%. The concept furthermore provides savings on the costly maintenance to the on-board APU, based on hours of operations. For the airports, the “Go Green on Ground” also means a reduction of the noise level to the benefit of the airport personnel, passengers and to surroundings in general.

Innovative Design

The ITW GSE 3400 PCA is the market's only modular PCA and designed around identical cooling modules. Even with one module inactive, the 3400 PCA continues providing cooled air thus resulting  in minimal downtime, avoiding delays and keeping aircraft turn-arounds on schedule. Moreover, the modules are easy to swap by a technician with no special skills and in 20 minutes only. The modular design further means big savings on spare part inventories.
