Company Profile

  • ITW GSE 2400 Compact GPU - The market's best choice

    The ITW GSE 2400 Compact GPU series is the market’s best choice when it comes to solid-state, point-of-use GPUs. It is small and simple, reliable and robust. It has all kinds of outstanding technical qualities from the unique output voltage at the aircraft plug, the common ITW GSE user interface, soft-ware update via USB to the standard overload capabilities that matches all types of aircraft.

    Optimum voltage at the aircraft plug

    The 2400 Compact GPU is equipped with the patented Plug & Play system. Therefore, you experience an outstanding voltage quality at the aircraft plug. This is what matters and what makes your aircraft accept the voltage from the GPU.

    The Plug & Play means that the ITW GSE 2400 Compact fulfills the stringent requirements of most installations as it compensates for long symmetrical output cables, unbalanced loads as well as various power factors. The magnetic wave-shaping topology ensures a clean input power with a unity power factor and a current THD less than 5%.

    The ITW GSE 2400 Compact also provides other outstanding features such as:

    • 400% standard overload which makes the GPU future-proof
    • ITW GSE common user interface
    • Maximum personal safety
    • Easy access for cable connection & vital components
    • Suits all types of aircraft incl. A380, A350, B787
  • ITW GSE 2400 Power Coil - The Aesthetic Power Solution for a neat, nice and pleasant apron

    Axa Power Quick Install symbol

    The ITW GSE 2400 Power Coil includes a 400 Hz, 90 kVA power supply and a cable coil in one single enclosure.

    This leaves the PBB and the apron nice and neat and pleasant to look at. Especially, where glass bridges is the preferred solution, the aesthetic aspect is important. The Power Coil works perfectly well with all sizes of bridges and all types of aircraft.

    Innovative Solution based on Experience

    The ITW GSE 2400 Power Coil offers a highly reliable and robust design including a front plate in stainless steel. The Power Coil has an improved cable guidance system that ensures easy and smooth cable handling.

    As a standard, the Power Coil comes with 24m of cable (useable length). However, the spacious housing has room for at least 28m cable. The cable is rolled completely into the housing after use. The rolling automatically stops when the plug head is level with the lower edge of the Power Coil thus leaving the apron free.

    • Less stress on the passenger boarding bridge
    • Supply all Aircraft (PF 0.8 – PF1)
    • Optimum voltage quality at the aircraft plug
    • High reliability and easy maintenance
    • Innovative design
    • ITW GSE Operator Interface
    • Downloads and Updates via USB

    Additional Advantages

    • Weight reduction compared to the traditional solution with a separate converter and a cable coil
    • Space saving
    • One complete, tested and adjusted system
    • Requires only mounting and mains input cable installation
    • No cable compensation / adjustment needed
    • Simplified mechanical installation
  • ITW GSE 7400 eGPU - for cleaner and greener airports

    The ITW GSE 7400 is a true game changer in the ongoing quest for lowering the environmental impact at airports. Zero CO2 and NOx emissions at the place of work and drastic reduction of noise is the key for achieving greener airports and better working environments. The 7400 GPU does just that! As the eGPU uses battery power (instead of diesel), it is practically clean and silent. Further the eGPU emits no NOX into its operating environment. In this way, it contributes significantly to a cleaner and safer working environment for your employees.

    Extreme Flexibility

    The ITW GSE 7400 eGPU is set to change how airports think about ground power without making compromises. It is independent due to the onboard battery packs and can easily be transported to wherever it is needed. The flexible 7400 eGPU provides the same outstanding, well-proven features as other ITW GSE solid-state GPUs, including accurate and clean output voltage at the aircraft plug, and individual phase regulation of each output phase. It can perform multiple turnarounds before it needs recharging, and can be recharged from any standard 50/60Hz socket.

    The combination of two well-proven technologies i.e. Nissan batteries at input and an ITW GSE solid-state converter at output has created the rock-solid eGPU that has already been successfully tested at Amsterdam Schiphol Airports.

  • ITW GSE 7400 JetEx 28 VDC eGPU

    The ITW GSE 7400 JetEx 28 VDC eGPU is a purely battery driven unit. Therefore, it is super quiet and emission free to the benefit of operators and staff. It also makes the eGPU ideal for hangar and for remote use as well.

    The eGPU can be used for engine start, ramp operations or for test of avionics. Actually, the 7400 has enough power to perform up to 100 engine starts on a full charge. If need be, the 28 VDC power unit can be charged simultaneously while delivering power to an aircraft.

    The ITW GSE 7400 JetEx 28 VDC eGPU combines two known technologies into one innovative GPU.
    The JetEx eGPU is powered by a 4 fourth-generation Nissan Leaf battery pack with a capacity of 40 kWh. The same type of battery as in all Nissan branded electric vehicles. Since 2010, over 400,000 of these vehicles have been sold, with close to 90,000 in 2018 alone.
    At the output of the eGPU is ITW GSE’s well-proven 28 VDC solid-state converter. This combination of two tried and true technologies has created the rock-solid eGPU.

    The ITW GSE 7400 JetEx eGPU is well suited to cover the power need for aircraft like the following:

    • Cessna Citation
    • Beechjet
    • Gulfstream G250
    • Dassault FalconJet
    • ATR 42 & 72
  • ITW GSE 3400 PCA - the world's only modular PCA

    ITW GSE has a comprehensive knowledge of controlling and optimizing 400 Hz units. We have combined this knowledge with expert know-how in aviation cooling technology. This leads to the creation of the ITW GSE PCA 3400 – the market’s most innovative, smartest and environmentally friendly PCA unit for de-centralized use.

    The ITW GSE PCA is the ONLY modular PCA on the market. You can exchange a cooling module in approx. 20 minutes and without dismounting the unit from the installation spot!

    Smart advantages of the ITW GSE 3400 Power PCA

    • Flexible, simple and innovative design
    • Easy and time-saving maintenance due to modular design
    • Savings on installation due to low input current
    • Optimal and efficient cooling thanks to variable frequency drives
    • Easy operation and maintenance
    • Passenger comfort and high air quality
    • Tested in a highly advanced in-house PCA climate chamber
  • ITW GSE 1400, 28 VDC GPU - small and easily maneuverable

    Durable Design

    The ITW GSE 1400 is a small, light and easy maneuverable solid-state GPU that does not take up much space neither in mobile nor in the fixed version.

    The solid-state technology means that wear and tear is limited to a minimum since there are no rotating parts.

    The result is a very reliable and dependable unit that is built to last for a long time. In case of service or repair, the canopy can be completely removed within minutes, thus leaving full access to all parts.

    Available in the following ratings:

    • 400A – 600A with peak loads of 1600 and 2400A
    • The units are available in mobile as well as in fixed versions.
  • ITW GSE 4400 Diesel GPU

    The ITW GSE 4400 series is available with a Cummins Tier 3 or Tier 4 engine so that no matter where you are located, we have a 400 Hz mobile driven GPU to meet your needs.

    The 4400 is a mobile, diesel-powered 400 Hz GPU that’s ideal for supplying power to all aircraft at places wherever you need an independent external power source. The GPU provides a quiet, fuel-efficient apron power system, and the unit is easy to move to where you need it – remarkably tough and supremely reliable.

    The engine, alternator, controls, batteries and cables are all easily accessible but completely protected under a tough, corrosion-free canopy made of resilient medium-density Polyethylene. All maintenance points that need to be checked regularly (fuel, oil, water, etc.) are easy to access. The entire canopy can be removed by hand in less than two minutes – no hoists or cranes needed.
