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.
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.
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.
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.
For the first time, a single ULTIMA unit serves multiple power modules simultaneously. One expanded baseplate replaces what previously required several individual heat sinks.
Pipe length extends, and air interface height increases to match your power requirements. Performance scales with height.
ULTIMA-X adapts to complex enclosures and irregular module layouts. Product designers get genuine freedom to design around the system.
