At Chillventa, DuPont will present new, lower-GWP refrigerants, working fluids and foam expansion agents based on hydrofluoroolefins (HFOs). These include Opteon® XP40 which can replace R-404A/R-507 in commercial and industrial medium- and low-temperature refrigeration systems.

Neu-Isenburg, August 2014. The DuPont Chemicals & Fluoroproducts' (DC&F) presence at this year's Chillventa from 14-16 October in Nuremberg will focus on new refrigerants, working fluids and foam expansion agents. These new products are based on hydrofluoroolefin (HFO) technology and, compared to previously used substances, offer benefits in energy efficiency and have a significantly reduced Global Warming Potential (GWP).

For instance, on stand 4-206, Hall 4, DuPont will present Opteon® XP40, a new member of its Opteon® family of low-GWP refrigerants. It has a GWP of 1397, which is 65 per cent lower than R-404A/R-507A, which it can replace in commercial and industrial medium- and low-temperature refrigeration systems. 

A further highlight at the trade fair will be novel, non-flammable working fluids with reduced GWP. These are suitable for use in high temperature heat pumps and organic Rankine cycles, as they boost energy efficiency at relatively high temperatures. Another new product is Formacel® 1100, a chlorine-free, high efficiency foam expansion agent for producing PU rigid foam insulation with zero Ozone Depletion Potential (ODP) and a GWP that is 99 per cent lower than that of HFCs normally used today.

DuPont experts will also present various technical papers about these new products during the Specialist Forums (http://www.chillventa.de/en/supportingprogramme/specialist-forums/).

Opteon® XP40 for stationary refrigeration systems – the future is clear!

Opteon® XP40 (R-449A) is a non-flammable refrigerant blend (ASHRAE Class 1) with similar thermodynamic properties to R-404A/ R-507A widely used today in medium- and low-temperature commercial and industrial direct expansion refrigeration systems. XP40 is suitable for use in both new systems and for cost-effective and simple retrofitting of existing systems. 

Having an approximately 65 per cent lower GWP than R-404A/R-507A, XP40 complies with the requirements of the new European F-Gas Regulation No. 517/2014 which comes into force from 1 January 2015. Over a period of 15 years this regulation will gradually reduce the number of tonnes of CO2 equivalents available on the market. This will result in a reduction of around 80 per cent by 2030 and will prohibit the use for service of HFCs with a GWP greater than 2500 in most applications from 1 January 2020. 

Opteon® XP40 has no ozone depletion potential and better energy efficiency than R-404A/R-507A. It can contribute significantly in reducing overall greenhouse gas emissions arising from leaks and energy consumption by refrigeration systems in supermarkets, cold stores and in industrial process cooling. Successful pilot projects have already demonstrated the benefits of Opteon® XP40 in a practical setting and these projects will be presented at the trade fair. 

The growing Opteon® family of low GWP refrigerants also includes Opteon® XP10 for hybrid cascades and Opteon® XP44 for transport refrigeration.

New low GWP working fluids for high-temperature heat pumps and organic Rankine cycles

At Chillventa, DuPont is also exhibiting new, developmental non-flammable working fluids with distinctly reduced GWP. These include DR-65 (GWP < 850) for high temperature lift applications of up to 65°C, DR-14A (GWP approx. 375) for heating at temperatures of up to 100°C and DR-2 (GWP of less than 10) for high efficiency, high temperature heat pumps for temperatures up to 160°C. Planning for commercial introduction of these products is underway.
As John McMenamin, Business Manager, DuPont Fluorochemicals Europe, Middle East and Africa (EMEA), says: "DuPont will continue to develop new products based on our ground-breaking HFO technology. Our new range of solutions with reduced GWP will assist our customers and their respective value chains in providing products that contribute significantly to ensuring refrigeration, foam insulation and heat pump applications are both energy efficient and environmentally responsible."
