2 Product description
General information
AHT products comply with EU Directive 1907/2006
(REACH) for the registration, evaluation, approval
and limitation of chemical materials.
In the product design, the manufacturer has
considered the environmental and disposal-
friendliness of the device, in particular, for the
refrigerant propane (R-290) and the propellant
pentane (for the insulating foam). Propane does not
have any ozone depletion potential (ODP) and only a
very low greenhouse potential (GWP) of 3. The
refrigerant R-404A is recorded in the Kyoto Protocol.
It does not have any ozone depletion potential (ODP)
and has a greenhouse potential (GWP) of 3922.
