Challenge
Scaling Sustainable Heat Pump Production with Reliable Electrical Control
Since its founding in 2020, Fenagy A/S has experienced remarkable growth. As a Danish OEM specializing in large sustainable refrigeration and heat pump systems, the company meets the rising demand for eco-friendly, energy-efficient solutions.
Their advanced systems significantly reduce energy consumption, helping clients lower operational costs and minimize their carbon footprint. By using only natural refrigerants like CO₂ and hydrocarbons, Fenagy ensures efficiency and minimal environmental impact compared to traditional synthetic alternatives. Powered by electricity, their systems further integrate renewable energy sources to limit reliance on fossil fuels—making them truly the most visionary heating and cooling systems in the world.
Developed for industries such as District Heating, HVAC, and Data Centers, the systems require reliable power control for uninterrupted operation. As Fenagy has grown, so has their need for more capable electrical switchboards.
In late 2023, they identified RLAY, a partner of CUBIC, a Rockwell Automation company, as their new supplier for the control panel operating their H-2600 Heat Pump and stainless steel enclosures for the system’s evaporators.
Fenagy faced three critical challenges in selecting a new supplier: “Our requirements change quickly, and new control panel solutions must be constantly developed. A new supplier must be able to support the development, deliver large quantities, and easily adapt production to keep up with demand and growth at Fenagy," says Niels Erik Bjerregaard, Electrical Engineer, Fenagy A/S.
A collaborative approach and technological expertise were essential to support the development of Fenagy’s electrical solutions.
Solution
Standardized Control Panel Design Powered by Partnership
After evaluating several candidates, Fenagy selected longtime CUBIC Partner, RLAY, for their collaborative approach, expertise, flexibility, and experience in series production. Within the first month, the first delivery was completed, and the relationship quickly evolved into a valuable partnership.
A crucial initial step was to conceptualize ideas and requirements into a standardized control panel solution that allows for effective and adjustable series production. Through sparring and constructive dialogue, RLAY’s extensive know-how became an important asset in the ongoing development and innovation of control panels tailored to Fenagy’s evolving needs.
Partnering with RLAY also provided Fenagy with valuable sparring, training sessions, and additional tools from CUBIC to further enhance development. In particular, the CUBIC Galaxy design software, which integrates with Fenagy’s existing electrical CAD software, enabled a transition from 2D to 3D design and full leverage of Digital Twin principles.
“Together, we have developed a standardized concept that allows for series production with the possibility to make adjustments based on the end-user's preferences. Both RLAY's knowledge and CUBIC's support and Galaxy software play an important role in this process,” says Niels.
RLAY’s modern 4,500 m² panel workshop and expertise in series production positioned them to meet Fenagy’s anticipated need for 70 control panels and nearly 450 customized stainless steel enclosures within the first year.
Being a CUBIC Partner allows RLAY to integrate the advantages of the CUBIC Modular System, simplifying and accelerating assembly to support large volumes and ensure consistent quality and shorter lead times.
“The CUBIC Modular System gives great flexibility and makes us more competitive. It supports our abilities in series production and allows us to efficiently meet high-volume demands while maintaining consistent quality and fast delivery times,” says Lars Farsø, CEO at RLAY.
