PREVENTIVE MAINTENANCE PROTECTS AND SAFEGUARDS.
Interruptions in the crucial cold supply are expensive and unproductive.Reliable refrigeration is essential for many industrial production and process applications. Through regular maintenance and preventive servicing, we help ensure the long-term availability of your refrigeration system and minimize the risk of unplanned downtime.
A professionally maintained system supports reliable and cost-effective operation. Regular inspections, functional checks and optimization recommendations can help reduce unnecessary energy losses, improve operational safety and extend the service life of your critical components.
At the same time, we support plant operators in meeting their legal and regulatory obligations. Depending on the installation location, these may include requirements relating to refrigerant management, environmental protection, occupational safety, pressure equipment and recognised engineering standards.
Our service technicians receive continuous technical training and hold the qualifications required for maintenance, servicing and refrigerant handling. They also undergo the necessary occupational health examinations required for work in demanding industrial environments, such as steel mills and heavy industry facilities.
AVAILABILITY STARTS WITH THE RIGHT SPARE PARTS STRATEGY.
We help secure the availability of your refrigeration system through the use of high-quality original spare parts supplied directly by equipment manufacturers.
During the design of new installations, we place particular emphasis on accessibility for maintenance activities. Components subject to regular wear or scheduled replacement can therefore be inspected and exchanged efficiently.
Should an unexpected failure occur, we do not simply replace individual components. We investigate the root cause of the problem and develop practical and economical solutions that provide long-term operational reliability, including for installations that are already beyond their warranty period.
We focus on identifying the cause of failures, not merely correcting the symptoms.

REPAIR, MODERNISATION AND RETROFIT
Planning and Engineering of Refrigeration System UpgradesWEISSHAAR has many years of experience in upgrading existing industrial refrigeration systems to improve operational reliability, energy performance and long-term compliance with modern refrigerant regulations.
In particular, we have established ourselves as a trusted partner for refrigerant conversion projects. As early as 1995, WEISSHAAR supported customers during the transition from the phased-out refrigerant R124 to R227, carrying out both in-house testing and extensive field trials.
Since then, regulatory requirements for refrigeration systems have continued to evolve.
Brief history and current overview:
Stratospheric ozone depletion and the atmospheric greenhouse effect caused by refrigerant emissions have led to drastic changes in refrigeration and air conditioning technology since the early 1990s.
The use of the former CFC refrigerants that contribute to ozone depletion, e.g. R12, R22 R12B1, is no longer permitted in industrialised countries, but there have been extended transition periods for the HCFC refrigerant R22. However, there was also an early phase-out of R22 in the European Union, which was implemented in several stages (R22 as a transitional refrigerant).
With the chlorine-free (ODP = 0) HFC refrigerants R134a, R404A, R407C and R227fa with R236ea widely used in industrial refrigeration, air conditioning and crane temperature control systems for years, new challenges are now on the horizon. These primarily concern the issue of the greenhouse effect. The aim is to significantly reduce direct emissions due to refrigerant losses and indirect emissions through the use of particularly efficient system technology.
Corresponding legal requirements already exist in this regard, such as the EU F-Gas Regulation 517/2014, as well as a number of regulations already ratified or in preparation within the framework of the EU Ecodesign Directive. Similar requirements are either in preparation or effective in Australia, Canada and the USA. At international level, the so-called "Kigali Amendment" was adopted in 2016 within the framework of the Montreal Protocol. This includes a phased reduction of HFCs ("HFC phase-down"), starting in 2019.
Although the indirect emissions from energy generation are disproportionately higher than the direct (CO2-equivalent) emissions from HFC refrigerants, restrictions or bans on the use of refrigerants with a high global warming potential (GWP) will come into effect in the future. This primarily pertains to refrigerants with a high to very high global warming potential, for which alternatives with a lower GWP are already available.
Over time, substitutes that have ever lower greenhouse equivalents are being introduced in stages to the market, with a tendency also towards combustible materials. We are careful here to achieve the goals set in a harmless, operationally reliable and economical manner.
In addition to new operator obligations, it is also necessary to observe the EU F-Gas Regulation 517/2014. We offer you individual retrofit packages and shall be happy to advise you on this in order to safeguard your investment in the future.
Refrigeration plants can often also be modified to meet the current regulations or retrofitted with energy-saving components. Please contact us for your individual quotation.
