Compressor-gekoelde klimaatkamers en incubators ICHeco / ICPeco nu CO2-gekoeld

Memmert introduceert twee temperatuurregulatie toestellen met klimaatneutrale CO2 als koelmiddel (R744) tijdens de ACHEMA 2018. De ICHeco-klimaatkamer en de ICPeco compressorgekoelde incubator zijn niet alleen milieuvriendelijker, maar ook efficiënter dan apparaten die met gefluoreerde broeikasgassen worden gekoeld.


CO2 refrigerant is climate-neutral

With the gradual phasing out of synthetic refrigerants, Memmert is expanding its range of environmentally friendly temperature control appliances. With the constant climate chamber HPP and the cooled incubator IPP, Memmert has already been offering Peltier-cooled, environmentally friendly temperature control appliances without a refrigeration compressor for many years.

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. 


F-Gas regulation provides incentives for conversion

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. "Memmert reacted early for several reasons," explains Stefan Kaufmann, Head of Development Department at Memmert. "On the one hand, our new eco appliances have a positive impact on our customers' environmental balance sheet, and on the other hand, they are virtually maintenance-free and score points with improved cooling capacity." Internal measurements with an ICH750eco showed a 20 % faster average change speed at an ambient temperature of 22 °C.

Both appliances also feature the proven Memmert air jacket temperature control system, via which both heat and cold are quickly introduced into the interior over a large area via four sides. The hermetically sealed working area offers numerous advantages: no dehumidification in the interior and thus no dehydration of sensitive samples and no icing over of the cooling unit. In addition, the climate chamber ICH does not consume any water after reaching the setpoints as long as the door is not opened.
