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.

3 Layout and function
The device is a compact device ready to plug in.
All individual devices are delivered ready for
operation and have their own control unit.
The devices are pre-programmed at the factory.
Each device contains one or more hermetically
closed refrigerant circuits, the components of which
