## ULTIMA's innovative design

#### Designed with large evaporators, ULTIMA ensures uniform cooling across the entire component, preventing localized overheating and optimizing heat dissipation. Its fully integrated structure eliminates additional thermal interfaces, enhancing efficiency, reliability, and manufacturability. Optimized for applications requiring leveled installation, ULTIMA delivers powerful, scalable thermal performance.

 ULTIMA

## Two Architectures. One Platform.

Both ULTIMA products are built on patented NEOcore thermosyphon technology and deliver significantly better thermal performance than traditional cooling methods. The difference is in how far you need to push your power stack.

Next GenerationULTIMA-X. For Maximum Power Density and Design Freedom

When your SiC modules are pushing beyond what standard heat sinks can handle, or your enclosure geometry makes a conventional solution impossible, ULTIMA-X is the answer. One expanded baseplate. Multiple modules covered. Free-form design to fit your exact layout.

Proven StandardULTIMA. For Reliable, Cost-Efficient IGBT Cooling.

When you need a proven, scalable two-phase cooling solution that fits a standard footprint and hits your cost targets without compromise, Classic ULTIMA delivers. A modular, standardized solution trusted in AC drives, BESS, and industrial converters worldwide.

 

 NEXT GENERATION · POWERED BY NEOcore-X

## ULTIMA-X. One Evaporator. Multiple Modules. Maximum Performance.

The next generation of the most efficient air cooling is here. ULTIMA-X combines an expanded baseplate with patented NEOcore thermal channels, delivering integrated 3D phase-change technology for high-density converter and inverter designs. The fully aluminium NEOcore-X evaporator eliminates thermal interfaces inside the heat sink, enabling the whole structure to work, not just the area directly above the module.

ULTIMA-X fits the installation envelope of conventional heat sink solutions. And when the application calls for something purpose-built, we engineer the solution around your geometry.

Multi-Module Coverage

For the first time, a single ULTIMA unit serves multiple power modules simultaneously. One expanded baseplate replaces what previously required several individual heat sinks.

Scalable by Design

Pipe length extends, and air interface height increases to match your power requirements. Performance scales with height.

Free-Form Geometry

ULTIMA-X adapts to complex enclosures and irregular module layouts. Product designers get genuine freedom to design around the system.

 Benchmarked head-to-head. Identical airflow. Identical load.
