itw gse 3400 pca Pre-Conditioned Air


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 ITW GSE point-of-use pre-conditioned air units are the market's only truly modular PCAs (patented). The ITW GSE 3400 is designed around identical cooling modules that can easily be swapped by a technician with no special refrigeration skills and in 20 minutes only. This smart and innovative PCA is available in the following models: 130 kg/min & 210kg/min.

Improve the Environment and Cut Cost

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.

Introducing the new ITW GSE 3500 PCA!

The new ITW GSE 3500 is the only PCA on the market that automatically adapts its airflow to the specific aircraft type - and not just to an aircraft category.

Innovative Design

The ITW GSE pre-conditioned air units are the only truly modular PCAs on the market 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 refrigeration skills and in 20 minutes only. The modular design also means big savings on spare part inventories.

Stepless Regulation

The 3400 design breaks completely new ground by using variable frequency drive technology that gives easy, stepless regulation of the discharge temperature. Therefore, the ITW GSE 3400 PCA units supply exactly the required amount of cold air and not more. They use much less energy than other PCAs that are designed for peak load conditions although these conditions probably only apply for 10-20 days each year. Those PCAs deliver excess capacity for about 80% of the time, wasting lots of expensive energy and creating undesirable emissions. Another advantage of the stepless regulation is less mechanical stress – which boosts reliability and service life and gives you a better return on investment.

The 3400 PCA uses a minimal amount of refrigerant due to micro channel condenser technology and the compact design of the unit. The R410A refrigerant does not degrade the ozone layer at all. The refrigerant further provides reliable operation at high ambient temperatures. The distance between the evaporators and the low air velocity optimize the efficiency of each cooling circuit and prevent condensation drops from moving from one evaporator to the next.
