ITW GSE 3400 Pre-Conditioned Air Unit, electric powered


ITW GSE 3400 PCA – the world’s only modular PCA

ITW GSE is a trustworthy partner designing and optimizing GSE equipment. We have strong expertise within cooling technology and the ITW GSE 3400 PCA is the market’s most innovative, reliable and environmentally friendly point-of-use PCA.

The 3400 PCA 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 3400 PCA is the market’s only true modular PCA.
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: ITW GSE PCA 130 (130 kg/min), ITW GSE PCA 210 (210 kg/min)

The 3400 PCA is designed to suit all types of aircraft from the Narrow-Body (Code C: A320) & Wide-Body (Code D: B767) equipped with 1 PCA connector over the Jumbo (Code E: B777) to the Super Jumbo (Code F: A380) equipped with 4 PCA connectors connected to two ITW GSE 3400 PCA 210 units. The PCA is available for bridge- or ground mounting plus in a mobile version.

The increasing focus on environmental issues means that airports aim to let an external preconditioned 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.
