Image result for Memmert appliances ICHeco and ICPeco now CO2-cooled

Memmert introduced two temperature control appliances with climate-neutral CO2 as the refrigerant. The ICHeco climate chamber and the ICPeco cooled incubator are not only more environmentally friendly, but also more efficient and economical to maintain than appliances cooled with fluorinated greenhouse gases. 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.

CO2 refrigerant is climate-neutral

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. It is a by-product of industrial processes, which is why far less energy is used for its production than for synthetic, fluorinated refrigerants. 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. On the one hand, the new eco appliances have a positive impact on customers’ environmental balance sheet. On the other hand, they are virtually maintenance-free and impress with improved cooling capacity. Internal measurements with an ICH750eco showed a 25% faster change speed at an ambient temperature of 22°C and a time saving of almost 20%. In addition, the measurements showed a reduced emission of heat.

Both appliances 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. With interfaces for programming, storage and printout of process curves, like all Memmert appliances they are network-capable, documenting all parameters.
