Reftronix - CO₂ Control Solutions for Modern Refrigeration and Heat Pump Systems

Danish Control Technology for Natural Refrigerants

Reftronix is a Danish technology company based in Sønderborg, focused on developing electronic control solutions for refrigeration and heat pump systems using natural refrigerants. Their CO₂/R744 controller platform is designed for companies that need reliable, energy-efficient and future-ready cooling technology.

As regulations and market expectations push the HVAC/R industry away from high-GWP refrigerants, Reftronix provides control systems that support the transition toward CO₂-based refrigeration, heat pumps and cloud-connected system management.

Why Reftronix Matters Now

The refrigeration and heat pump industry is changing rapidly. F-Gas regulation, energy-efficiency requirements and the need for lower climate impact are forcing retailers, OEMs, system builders and service companies to rethink how cooling systems are designed, controlled and monitored.

Reftronix helps make that transition easier by combining CO₂ control hardware, cloud-based monitoring, analytics and application know-how into one technology platform.

EU’s revised F-Gas Regulation, Regulation (EU) 2024/573, strengthens the phase-down of HFCs and moves the market toward alternatives with lower climate impact, including natural refrigerants.

Core Reftronix Solutions

Reftronix offers a family of CO₂ controllers and cloud-connected technologies for different refrigeration and heat pump applications. Their platform includes control solutions for condensing units, chiller systems, pack and booster systems, room and cabinet control, heat pump control and cloud-based monitoring.

Reftronix’ own website lists CO₂ controller categories including Cloud Platform, Condensing Unit Controller, Chiller Systems Controller, Pack & Booster Systems Controller, Room & Cabinet Controller and Heat Pump Controller.

Who Reftronix Is For

Reftronix is relevant for companies and decision-makers working with commercial refrigeration, heat pumps, supermarket cooling, industrial refrigeration, OEM system design, energy optimization, service operations and the transition to natural refrigerants.

The solution is especially relevant for organizations that need to reduce refrigerant-related climate risk, improve energy performance, simplify commissioning and gain better visibility into system operation.
