Calyos, a leader in advanced two-phase cooling solutions, has successfully reached pivotal design milestones in March for its technology demonstrators within the Clean Aviation projects TheMa4HERA and HE-ART. These achievements mark significant progress in enhancing thermal management systems for next-generation hybrid electric regional aircraft.
The TheMa4HERA project focuses on developing innovative technologies to manage the substantial heat dissipation challenges posed by hybrid electric power and propulsion systems in regional aircraft. Traditional thermal management systems handle approximately 35-50 kW of heat; however, future hybrid electric regional aircraft are expected to require systems capable of managing between 300 to 1,000 kW. TheMa4HERA aims to mature major technology components to Technology Readiness Level 5 (TRL5), addressing these increased demands.
In parallel, the HE-ART project is dedicated to demonstrating the feasibility of a hybrid electric turboprop system through a comprehensive ground test demonstrator. This initiative integrates an electric drivetrain with an ultra-efficient thermal turboprop engine, compatible with 100% sustainable aviation fuel. The objective is to achieve efficiency improvements and reduce greenhouse gas emissions by up to 30%. Key technologies being integrated include advancements in core thermal engines, electric drivetrains, electrical distribution systems, gearboxes, propellers, nacelles, and heat exchangers.
Within these projects, Calyos is instrumental in advancing passive two-phase Capillary Jet Loop technology to higher TRLs. This technology is pivotal for efficient power electronics cooling and effective heat transfer applications, both critical for the performance and reliability of hybrid electric regional aircraft.
Following the successful completion of these critical design milestones, Calyos is set to commence the manufacturing of prototypes. Subsequent laboratory testing will be conducted in collaboration with key consortium partners, aiming to validate the performance and integration of these thermal management solutions within the broader aircraft systems.

Wings ProjectWho We Are
Calyos is a leader in the design and manufacture of two-phase thermal management systems. Building on our heritage from Euro Heat Pipes (EHP) and their space technology expertise, we specialize in innovative cooling solutions that tackle the thermal challenges of tomorrow.
What We Do
We engineer advanced cooling technologies, including loop heat pipes, micro-channel heat pipes, and pulsating heat pipes, to optimize thermal performance across a variety of applications. Typically these include: power electronics, processors, and batteries, but we don't stop there we are continuing to develop and produce fully customizable solutions for other specific needs, for example e-motors and fuel cells.
Where We Operate
Calyos is headquartered in Charleroi, Belgium, where our engineering and production teams work side by side in a state-of-the-art facility. From this base, we serve a global clientele, providing our cutting-edge solutions across North America, Asia, Europe, and South America.
When We Started
Calyos was incorporated in 2014 as a spin-off from Euro Heat Pipes (EHP), which was established in 2001 and has become a major player in the European satellite market. Since then, Calyos has been adapting and evolving EHP's space-grade cooling technologies for terrestrial applications.
Why We Matter
Our mission is to lead the industry towards adopting the most effective and sustainable thermal management solutions. We aim to address the most pressing thermal challenges in the data-driven and electrified environments of today, leveraging passive cooling technologies to achieve superior efficiency and environmental stewardship.
How We Succeed
Our success is driven by our commitment to four core values:
1. Applied Knowledge - Transforming deep technical expertise into market-ready solutions.
2. Better Together - Emphasizing collaboration with all stakeholders to enhance our collective success.
3. Inherent Flexibility - Adapting our solutions and practices to keep pace with evolving market demands.
4. Continuous Research - Persistently innovating to maintain our leadership in thermal technology.
