In recent years, CO₂ refrigeration technology has emerged as a possible game changer in the field of environmental simulation. With evolving regulations and a growing focus on sustainability, Weiss Technik has stepped up, delivering a cutting-edge solution that aligns with the latest European Union regulations. In this blog ‘CO₂ Refrigeration Technology: The Future of Cooling’ explores the revolutionary changes in Weiss Technik’s refrigeration systems and the key advantages that CO₂ refrigerant offers.
As discussed in our previous blog ‘FGas Regulations and What It Means for Our Customers’, the landscape of refrigeration technology has shifted due to the introduction of stricter EU FGAS regulations. These new rules, effective for new chambers introduced after December 31, 2024, limit the global warming potential (GWP) of refrigerants used in portable equipment. The stipulation is clear: no refrigerant with a GWP greater than 150 can be used unless the equipment cools below -40°C.
Weiss Technik swiftly responded to these regulatory changes, becoming the first such company to offer a comprehensive solution by adopting CO₂ refrigerant. They began by redesigning their -40°C chambers and are now expanding this eco-friendly refrigeration technology across their entire product range.
Weiss Technik’s CO₂ refrigeration systems bring significant environmental and operational benefits. Here’s how they stand out:
The key advantage of CO₂ refrigerant is its GWP of just 1, making it a vastly greener option compared to synthetic refrigerants. This positions CO₂ as an ideal solution for businesses looking to reduce their environmental footprint.
With CO₂ refrigerant, the chambers can now reliably achieve temperatures as low as -50°C, improving the overall capability and flexibility of the systems.
CO₂ refrigeration technology offers virtually linear cooling rates down to -40°C, providing faster and more consistent cooling, which is particularly useful for precise temperature control in laboratory environments.
CO₂ refrigeration systems not only provide competitive pricing, but in many cases, the performance surpasses that of previous models. Laboratory requirements remain unchanged or, in most instances, are improved with the transition to CO₂ technology.
Previously, chambers needed a -70°C cascade refrigeration system to reach – 50°C. With the new CO₂ systems reliably cooling to -50°C, the energy consumption has been significantly reduced. Additionally, the elimination of the cascade system leads to lower investment and potential service costs.
The noise levels from the CO₂ refrigeration system are dramatically reduced, as the compressors run much more quietly compared to older systems.
CO₂ refrigeration systems consume less power, leading to reduced operating costs and a more sustainable operation over time.
With CO₂, there is no need for annual leak tests, which saves both time and costs.
Even with all these improvements, the physical footprint of the CO₂ chambers remains unchanged, meaning they can fit seamlessly into existing setups.
With rising refrigerant prices, using CO₂, a more economical refrigerant, adds further value by reducing the overall cost of ownership.
Weiss Technik’s innovative CO₂ refrigeration technology is now available across a variety of their chambers, including:
– LabEvent: Capacities from 34 to 500 liters
– ClimeEvent: Capacities from 180 to 3,600 liters
– ClimeEvent: Capacities from 9 to 40 m³
– PharmaEvent: Capacities from 600 to 2,000 liters
Additionally, chambers designed for special applications, such as SunEvent, SaltEvent, ShakeEvent, AirEvent and EmissionEvent, will also be available with CO₂ cooling technology.
Weiss Technik’s introduction of CO₂ refrigeration technology marks a significant leap forward in sustainable and efficient cooling systems. By embracing CO₂, Weiss not only meets the stringent new EU regulations but also delivers systems that offer superior performance, lower costs, and a reduced environmental impact.
As businesses worldwide look to align with greener practices, Weiss Technik’s CO₂ refrigeration systems are the ideal choice for forward-thinking companies.
