ITW GSE has the power to cover your needs no matter which type of Ground Power Unit you are looking for. We supply 400 Hz solid-state GPUs, diesel GPUs, gasoline GPUs or even battery GPUs. We also supply 28 VDC solid-state or diesel GPUs or a combination of 400 Hz and 28 VDC GPUs. We got you covered. ITW GSE is a leading supplier of Ground Power Units to the airport industry with roots stretching back nearly 100 years. If you are in aviation and haven't yet done business with ITW GSE, there are some very good reasons for getting to know us. At ITW GSE, we monitor the market and are at the forefront of new aircraft requirements and market developments.

The ITW GSE 3400 PCA is the market's most innovative, reliable and environmentally friendly point-of-use Pre-Conditioned Air unit.

The 3400 PCA is also the market's only true modular PCA. It supplies fresh, clean air into parked aircraft at carefully monitored temperatures. This provides a pleasant atmosphere for the crew and the next passengers and helps make aircraft turn-around faster and more effective.

ITW GSE is a trustworthy partner designing and optimizing GSE equipment. We also have strong expertise within cooling technology. The combination of those capabilities is at the origin of the smart 3400 PCA design.


The 3400 PCA can be installed underneath passenger boarding bridges. It can also be apron mounted or mobile. It is designed to suit all types of aircraft from the Narrow-Body (Code C: Airbus 320) & Wide-Body (Code D: Boeing 767) equipped with 1 PCA connector over the Jumbo (Code E: Boeing 777) to the Super Jumbo (Code F: Airbus 380) equipped with 4 PCA connectors connected to two ITW GSE 3400 PCA 210 units.


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.

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 ITW GSE 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.


The ITW GSE operator interface is easy and intuitive. This is your guarantee for correct operation and on-time aircraft departures. The operator only has to press the combined start/stop button. Also, he can monitor various parameters such as temperature and air flow at the display screen.

The operator interface is common from one ITW GSE product to another. Therefore, airport staff familiar with one ITW GSE product can easily switch to another as the icons and display are the same. For easy set-up and maintenance purposes, there is a deeper level dedicated for the technician. The software-based control system means that your 3400 PCA can be updated and given additional capabilities in the future, simply by transferring new software from a USB stick.

With an in-depth knowledge of the Ground Support Equipment industry, ITW GSE combines customer-back innovation to develop and deliver solutions that are tailored to your needs. As a result, you get cleaner and more reliable ground support systems that improve the working environment for your staff and increase the efficiency of your operations.

The backbone of all ITW GSE design is our common design platform that offers significant advantages.All products are equipped with the ITW GSE icon-based user interface. It is easy and intuitive to use - just like a smart phone or tablet. Airport staff that is already familiar with one ITW GSE product, can easily operate another since the display and the icons are the same. Less human errors during operation, simple product training, reduced spare part requirements and quick service and repair are advantages of the ITW GSE Way of Thinking.

We invented the patented ITW GSE Plug & Play system that provides unique voltage at the aircraft plug. We also designed the market's only modular PCA with easy-swap cooling modules, and the 2400 Power Coil, which combines a converter and a cable handling system in one self-contained unit.We provide experience you can count on.
