URT is the world's leading manufacturer of refrigerator disposal plants. For over 25 years URT engineers are working in this field and creating plant concepts for the different customer demands. More than 50 plants worldwide are equipped with the URT technology.
URT refrigerator recycling plants have achieved excellent results especially in the field of CFC's (VFC) recovery. The changeover to CFC-free refrigerants and blowing agents (VHC) was a new and further challenge for URT engineers, because substitutes are flammable and explosive. URT is offering different concepts for the recovery of blowing agents.
Employees of URT are working in different national and international working groups in order to submit their specialized knowledge to be integrated also in regulations and laws.
URT fridge disposal reference plants are located in Europe, North America, South America and Asia.
Fridge disposal plants for VHCs and VFCs
The ozone layer is an important part of our ecosystem and protects us daily against strong, ultraviolet radiation of the sun. A chemical balance ensures that a relatively constant layer thickness remains. Due to their volatileness, chlorofluorocarbons (VFC), released on earth, simply get into the earth´s atmosphere and reach the ozone layer at a height of about 20 km.
The CFC blocks the ozone production there. The local reduction of the ozone layer is the result. During the 70s and 80s it was found out that mainly the VFC used in the in-dustrial sector were responsible for this process and the reduction was started. 195 countries signed the Montreal-protocol in 1989 and resign to use these greenhouse gases mainly nowadays. Substitute materials which have similar physical characteristics but are much more environmentally friendly are used rather now. However, it must be considered that VFC was used in many ways and, despite of prohibition of processing in Europe, VFC is still contained in many products from the past. There is still a huge amount of end-of-life cooling devices on the market which contain not only polyurethane foam in the insulation body but also cooling agents strongly contaminated with VFC. This fact requires to dispose such end-of-life cooling devices properly and to separate CFC with suitable processes. The company URT Umwelt- und Recyclingtechnik GmbH has constructed plants for more than 20 years, which dismantle a cooling device in several work steps, separate them into single components and partially feed to the recycling process. It is very important that this process takes place in a closed room in order to avoid VFC gases escaping to the ambient air.
VHC-selective fridge disposal plants
No more CFCs have been used for the production of cooling devices in Europe since 1995. Those cooling devices which have been produced with substitute materials for the last 2 decades meanwhile represent a considerable part. A common characteristic of all substitute materials for cooling agents and propellants is the flammability of these materials. For this reason, all treatment plants must be constructed as fire and explosion-proof. URT has already realized various concepts successfully. In case of new plants, it is quite reasonable to treat VHC (volatile hydro carbons) and VFC end-of-life cooling devices differently, as the operating costs can be reduced considerably if using different device treatment systems.
