IPEload series

Our IPEload load units are compact systems for thermodynamic loading of refrigerant compressors, e.g. from the automotive sector. The IPEload can be used to test both electric (eKMV) and mechanically driven refrigerant compressors (mKMV) under various thermodynamic load conditions. For maximum flexibility, the IPEload is available for both the chemical refrigerants R134a and R1234yf as well as the natural refrigerants R744 (CO2) and R290 (propane).

IPEload-04-AW

Fully automatic control for efficient compressor testing

The IPEload-04-AW was developed for users who require automated and dynamic test sequences. Software such as IPEmotion can be used to create complete test program, which the system then runs fully automatically - ideal for complex and time-critical applications such as NVH analyses, dynamic load cycles or long-term tests.
The automatic control enables reproducible measurement series with flexible load curves without the need for manual intervention. This makes the 04-AW particularly suitable for development environments that require high precision, repeatability, and controllability.

Energy efficient: Low power consumption due to optimized thermal design
Compact & flexible: Suitable for laboratory and series testing
Easy integration: Connection via CAN, Profinet, Profibus, or analog/digital interfaces
Future-proof: Ready for R744

IPEload-04-MW

Mechanical loading technology for stable test environments

The IPEload-04-MW is the right choice for users who require static and stable load points. All settings are made using mechanical controls and will remain constant until manually changed. Thanks to the absence of electronic components, the 04-MW is ideal for EMC applications, as no electrical interference fields can arise.
The mechanical design ensures maximum operational reliability, even in demanding test environments. This makes the 04-MW particularly suitable for endurance runs, comparative tests, or situations where smooth, unadulterated measurement is crucial.

Energy efficient: Low power consumption due to optimized thermal design
Compact & flexible: Suitable for laboratory and series testing
Future-proof: Ready for R744

IPEload-05-MW

Mechanical load technology for stable test environments and different refrigerants

The IPEload-05-MW is the mechanical hybrid solution for users who need to switch between R290 and R134a/R1234yf while maintaining static and stable load points.
By eliminating electronic components, it is ideal for EMC-sensitive environments, where electrical components could influence the measurement results.

All load parameters are controlled directly mechanically, remaining constant until adjusted manually. As a result, the 05-MW delivers interference-free, stable, and particularly comparable measurement results - ideal for endurance runs, reference tests, or EMC-related test applications.

Full flexibility: Test today for tomorrow. Can be used with R290 or R134a/R1234yf
Proven performance: Precision and reliability from the IPEtec test environment
Save space & resources: One unit for two applications - less effort, more efficiency
Future-proof: Ready today for new refrigerant requirements, with the highest safety standard for R290
