F-gases: Piping systems for better alternatives

Fluorinated gases or F-gases are a family of man-made gases consisting of HFCs (hydrofluorocarbons), PFCs (perfluorocarbons) and SF6 (sulphur hexafluoride). F-gases have a very high GWP (Global Warming Potential). This means they have a large negative impact on global warming. HFCs accounts for the largest share of F-gas emissions. They are used in various sectors and applications, such as refrigerants. SANHA offers excellent piping systems to transport more environmentally friendly alternatives.


Stronger Regulations

With the growing urgency of tackling the climate crisis and in the light of the European Green Deal, the importance of stricter F-gas regulations has become more and more clear. Currently, the EU is taking regulatory actions to control F-gases as part of its policy to combat climate change.

The F-gas regulations were originally enacted in 2006 and revised in 2015. The main goal of these regulations is to phase down F-gases which carry a high GWP value and to replace them with environmentally friendly alternatives. To this end, measures and initiatives are being developed at global, European and regional level. Some of the most important developments are:

- Since 2020, it is already prohibited to install new cooling applications with HFCs who carry a GWP value of more than 2500. The use of newly produced F-gases with a GWP value of more than 2500 in existing cooling systems will also be phased out.

- From 2022 onwards, GWP value of such installations will be limited to 150.

 The main goal of these regulations is to reduce F-gas emissions with two-thirds of 2014 levels by 2030 and move towards more climate-friendly technologies.

CO2 as climate friendly alternative

As from 2022 regulations on the use of F-gases will be even more strict, the time is now to switch to more climate-friendly alternatives. Currently, great innovations in the refrigeration sector are being developed. One of the best alternatives available to using F-gasses in large refrigeration systems is switching to CO2.

To meet the strict requirements, more and more industrial and commercial refrigeration plants are indeed preferring CO2 as natural refrigerant. With a GWP value of 1, CO2 is the most environmentally friendly alternative. It is energetically very attractive compared to conventional refrigerants and can even lead to energy savings of up to 25%.

SANHA provides the solution

SANHA is at the frontline of these new developments. For the application of industrial and commercial refrigeration with CO2, SANHA offers its RefHP® piping system. The solder fittings and pipes are made of copper-iron (CuFe2P, CW107C) and are designed especially for climate friendly refrigerants such as CO2. The system is suitable for operational pressures up to 130 bar at working temperatures of up to 150°C. The range of fittings is available up to 2 5/8”. A special range of fittings for cool unit builders is available as well.

Installation companies and cooling unit builders prefer solutions in copper-iron instead of (stainless) steel. The advantages are numerous. The installation cost is much lower, because the fittings can be soldered instead of TIG welded. This is 2,5 times faster and eliminates the need of relying on expensive external TIG welders.

With the implementation of stricter regulations of F-gases, the use of CO2 refrigeration systems will increase at an exponential rate in the future. With our RefHP® system, SANHA provides the optimal solution in order to support this. More information on RefHP® can be found here.
