Power by the Hour


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.

The truly modular design is unique to the ITW GSE's pre-conditioned air units, creating innovative, efficient and reliable point-of-use PCAs. The ITW GSE 3500 is designed around interchangeable cooling modules that are easily swapped in only 20 minutes by technicians with no special skills.

This state-of-the-art PCA unit supplies fresh, clean air into parked aircraft at carefully monitored temperatures and provides a pleasant atmosphere for both crew and passengers.

Improve the Environment and Cut Costs

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.


Smart Advantages:

  • Automated Aircraft Type Detection through Integration with VDGS/BMS etc.
  • 400 Hz GPU built in for PCA 150 (60/45 Ton) - option
  • Reduced infrastructure costs with Intelligent Power Management
  • Maximum uptime due to modular design
  • Optimal and efficient cooling thanks to Variable Frequency Drives Compressors and Blower
  • Manufacturing in Denmark, Europe and Florida, USA
Automated Aircraft Type Detection

Improved Passenger Comfort

The PCA includes an integration to the Visual Docking Guiding System or to the Airport Building Management System and similar systems. This means that the PCA automatically receives information on the arriving aircraft type as soon as the aircraft approaches the gate.

From its aircraft data base, the PCA knows the exact aircraft settings and not just the generic aircraft category. Therefore, it will adapt the airflow settings and will provide the most optimum airflow for each specific aircraft. This helps to avoid operator errors and increases the PCA cooling performance by up to  54% and improves the passenger comfort.

Optimal and efficient cooling

The ITW GSE 3500 PCA makes it possible to limit the current drawn from the airport power supply. This ensures that the PCA does not overload the mains supply, thus, reducing the risk of blowing fuses and aircraft delays. If the airport should choose to upgrade the infrastructure, the current limit can easily be set to another value allowing the PCA to cool more and keeping the passengers comfortable.

The excellent high-power factor of > 0.97, results in a line current reduction of up to 20% compared to similar PCA units with the same rating. The current reduction also means that smaller and less costly cables can be used.

Further reductions on the energy consumption are achieved due to the variable frequency drive (VFD) control of all main parts such as compressors and blowers. Therefore, the lifetime costs of the ITW GSE 3500 PCA are as low as they can possibly be.

Finally, state-of-the-art components ensure a high performance at the output as well as a low energy consumption.

Stepless Regulation

The 3500 design includes updated variable frequency drive technology that gives easy, stepless regulation of the discharge temperature.

Therefore, the ITW GSE 3500 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.

vfd pca

The 3500 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 optimizes the efficiency of each cooling circuit and prevent condensation drops from moving from one evaporator to the next.

Modular Design

The ITW GSE 3500 PCA is a truly modular PCA.

  • Replace a module in less than 20 min
  • No welding to be done at gate
  • Improved MTTR
  • Common refrigerant circuit for 150 & 210
  • An inoperative module will NOT shutdown the PCA
  • Module removable even when PCA unit mounted underneath PBB
  • Cleaning the internal plenum in less than 2h30
