Memmert has launched two temperature control appliances with climate-neutral CO2 as the refrigerant (R744) during ACHEMA 2018. The ICHeco climate chamber and the ICPeco compressor-cooled incubator are not only more environmentally friendly, but also more efficient than appliances cooled with fluorinated greenhouse gases. Experience unparalleled homogeneity of temperature and humidity. For stability testing according to ICH - WHO - EMA - ASEAN- GMP - GLP – GCCP.
The climate chamber ICHeco is virtually maintenance-free, extremely powerful and environmentally-friendly. Compared to appliances with refrigerant R134a, it scores with faster change speeds during cooling. For a transition period, the Memmert climate chambers ICH / ICH L / ICH C with refrigerant R134a will be available in parallel.
Experience an average of 20 % faster temperature change rates with a CO2-cooled compressor (measurement ICH750eco at an ambient temperature of +22 °C according to IEC 60068-3-5).
Not all climate chambers are the same. The humidity content of the chamber load, the ambient conditions, and the respective temperature-humidity working range are decisive factors in the selection of the right appliance.
CO2 refrigerant is climate-neutral
With the gradual phasing out of synthetic refrigerants, Memmert is expanding its range of environmentally-friendly temperature control appliances. The European Union's new F-gas regulation aims to reduce emissions of fluorinated greenhouse gases by around 90 % by 2050 compared with 1990. Measures include gradual reductions in volumes and bans on placing it on the market. For example, new commercial refrigerators with a GWP greater than 150 may no longer be sold from 1 January 2022.
The GWP value (Global Warming Potential) is used to compare the effects of substances on the warming of air layers near the ground and thus on the greenhouse effect. The refrigerant used with immediate effect in Memmert ICHeco/ICPeco appliances with the abbreviation R744 and the chemical molecular formula CO2 has a GWP value of 1 and is therefore practically climate-neutral. By contrast, the refrigerant R134a, with a GWP of 1430, contributes 1430 times as much to the greenhouse effect in the first 100 years after its release. In addition, R744 does not contain chlorine, is neither flammable nor toxic, does not cause ozone depletion in the atmosphere and does not need to be disposed of or recycled. This is a by-product of industrial processes, which is why far less energy is used for its production than for synthetic, fluorinated refrigerants.
