Temperature control built for the future: Meet the HRSC F-Gas Compliant Chiller

A direct replacement for the HRS model, now with natural refrigerant and full regulatory compliance

The European Union´s accelerated phase-out of fluorinated greenhouse gases (F-Gases) is reshaping industrial cooling and temperature control. With increasingly strict regulations in force, companies across manufacturing, medical, food & beverage, and other sectors are under increasing pressure to adopt eco-friendly, sustainable temperature control technologies.

Legacy industrial chillers using high-GWP (Global Warming Potential) synthetic refrigerants are no longer a viable option. Non-compliance with the latest F-Gas legislation risks severe financial penalties, operational downtime, and reputational damage. The SMC HRSC Circulating Fluid Temperature Controller meets this challenge with a fully F-Gas compliant design using natural CO₂ (R 744) refrigerant – setting a new benchmark for environmentally responsible, regulation-ready industrial temperature control.

Discover HRSC: Next-generation CO₂ temperature control for compliance and performance

The HRSC Circulating Fluid Temperature Controller is a next-generation industrial cooling solution designed specifically for the era of natural refrigerants. Developed as a direct, 100% drop-in replacement for the HRS Series thermo-chiller, it offers companies an effortless way to modernise their temperature control systems without compromising performance, safety, or compliance.

Engineered to use natural CO₂ (R-744) – a non-flammable, non-toxic, and low-GWP (GWP=1) refrigerant – the HRSC ensures your operations remain fully F-Gas compliant, while contributing to your environmental and sustainability goals. Its robust construction and compact footprint make it ideal for industrial process cooling applications that require precise thermal management and long-term reliability.

Backed by SMC’s renowned quality standards, the HRSC is not only built to meet today’s regulatory demands – it’s designed to exceed them. Whether you are transporting by air, operating in sensitive environments, or aiming for sustainable innovation, the HRSC provides the confidence, safety, and energy efficiency your business needs to stay ahead.

Still relying on F-Gases? Here is why CO₂ is the safe and sustainable future of industrial temperature control

As EU and UK F-Gas regulations phase out harmful fluorinated gases, CO₂ (carbon dioxide) has become the leading natural refrigerant for industrial cooling and temperature control. With a Global Warming Potential (GWP) of just 1, CO₂ offers a safe and environmentally responsible alternative that aligns with the most stringent environmental regulations.

Unlike many synthetic high-GWP refrigerants, CO₂ is non-toxic, non-flammable, and free from transport restrictions, making it ideal for global logistics and sensitive industrial applications. Its high energy efficiency enables compact chiller system designs and delivers consistent temperature stability, even under demanding manufacturing and process conditions.

Switching to CO₂ -based circulating fluid temperature controllers isn’t just a regulatory move – it’s a smart, future-proof investment in safety, sustainability, and long-term cost efficiency for your industrial temperature control systems.

Key benefits of CO₂ as a refrigerant:

• Natural and sustainable: Zero ozone depletion and minimal climate impact
• Safe: Non-toxic, non-flammable ASHRAE 34 A1 classification
• Efficient: High thermal conductivity for improved cooling performance
• No transport restrictions: Safe for air, land, and sea freight
• Regulatory-ready: Fully compliant with current and future EU F-Gas regulations

Note: CO₂ has a Global Warming Poten tial (GWP) of 1 – the lowest possible value and the reference baseline defined by the IPCC and recognised in EU F-Gas legislation.
