Enhancing environmental care (measures for the RoHS Directive and the refrigerant reduction)
Every unit is in compliance with the RoHS Directive,* which stands for the Restriction of Hazardous Substances:
Lead-free soldering is used to avoid Lead Groundwater Contamination on the print board. The amount of
refrigerant on the unit has also been reduced to enhance environmental care.
* RoHS Directive: the restriction of the use of certain hazardous substances in electrical and electronic equipment that has been sold in EU since July 2006
History of refrigerant
R22, an HCFC-based refrigerant, has been a popular choice for most chillers. R22 has been targeted by the
Montreal Protocol to be phased out in new equipment. Additionally, governments in many countries are enforcing a
ban of HCFC-based refrigerants for new installations.
Because of these restrictions, R410A refrigerants are desirable. R410A is a blend of HFCs, which do not deplete
the ozone.
Technical aspects of refrigerant
New Design
R410A is a more efficient refrigerant as it has a higher specific heat capacity when compared to R407C or R22.
This higher energy carrying capacity allows for smaller pipe sizes, longer pipe runs and reduces the volume of
refrigerant within a system. This is a major factor when concerning safety and environmental requirements in the
design, manufacture, installation, operation, maintenance and disposal or refrigerating systems.
