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 unit's truly modular design is unique to ITW GSE, and ensures exceptional efficiency and reliability in a point-of-use PCA. The ITW GSE 3500 is designed around interchangeable cooling modules that are easily swapped in only 20 minutes.

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.

Reduce your carbon footprint and costs

Carbon reductions are top of mind for airports worldwide. Our "Go Green on Ground" concept can reduce parked-aircraft emissions by 80–85% by replacing the aircraft's APU with a 400 Hz solid-state GPU and a pre-conditioned air unit.

In addition to the environmental win, this solution saves on costly APU maintenance and benefits passengers, airport staff and the the airport's general surroundings via significant noise reduction.


Smart advantages

  • Automated Aircraft Type Detection through integration with VDGS or BMS
  • Optional built-in 400 Hz GPU (model 150, 60/45 ton)
  • Savings on infrastructure costs with optional Intelligent Power Management (IPM)
  • Maximum uptime thanks to modular design
  • Efficient optimal cooling via innovative VFD, compressor and blower
  • Manufactured in Denmark and Florida

The beating heart of EcoGate

The 3500 is much more than just a PCA. It also forms the centerpiece of EcoGate, a high efficiency system of ground support units that work together intelligently. By linking your GSE equipment together in an integrated system, EcoGate unlocks new efficiences and removes power-related barriers to progress at the gate.

The 3500 with IPM hosts several technologies that EcoGate depends on, including IPM itself. IPM monitors power consumption and allocates power dynamically, always prioritizing the needs of your GPUs and keeping total power consumption beneath a preset limit.

Automated Aircraft Type Detection

Improved passenger comfort

The 3500 enhances passenger comfort via a new Automated Aircraft Type Detection (AATD) technology that integrates with your VDGS or BMS solution.

As the aircraft approaches the gate, AATD enables the 3500 to recognize its exact aircraft type – not just the category. The 3500 then automatically sets the optimal airflow settings, improving PCA cooling performance by up to 54% and reducing the risk of operator error.

Automated Aircraft Type Detection - how it works

Check out the video and learn how the Automated Aircraft Type Detection adapts the airflow to optimize cooling and passenger comfort.

Optimal and efficient cooling

When equipped with Intelligent Power Management (IPM), the 3500 enables you to set limits on how much current is drawn from the airport power supply. This ensures that the PCA will not overload your supply and risk blowing fuses or delaying an aircraft departure. If you upgrade your power infrastructure, you can easily raise your preset limit to continue providing sufficient cool air and maintain passenger comfort.

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 energy savings are achieved via variable frequency drive (VFD) control of all main parts, including compressors and blowers. This ensures an absolute minimum total lifetime cost of your 3500 PCA. In addition to energy savings, state-of-the-art components ensure high performance at the output.

Stepless regulation

The 3500 design includes updated VFD technology that allows for easy, stepless regulation of the discharge temperature.

This means the 3500 supplies exactly the right amount of cold air, never more. It also consumes far less energy than other PCAs, which are typically designed for peak load conditions that normally only apply 10–20 days per year.

Along with saving energy, stepless regulation helps lower emissions at the gate and reducess mechanical stress, improving reliability and extending the 3500's service life.

vfd pca

The 3500 PCA uses a minimal amount of refrigerant thanks to micro channel condenser technology and the unit's compact design.

R410A refrigerant causes no degradation of the ozone layer, but ensures reliable unit operation at high ambient temperatures.

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
