“The measuring equipment makes it easier and more efficient for me to do all the cooling jobs.”

Cooling technician William Giorgi regularly reviews systems and associated technologies to ensure the right climate in cleanrooms and warehouses at medtech company Wellspect HealthCare. An important part of the job going forward is to create sustainable cooling solutions.

William runs Kyl & Industriteknik i Väst AB together with Johnny Olofsson and two employed refrigeration technicians, Josefine and Emil. The quartet works with a range of repeat clients where they are “the centerpiece of a property or process”, as William puts it.

– Our aim is to have a wide range of knowledge that makes us a long-term partner. We are familiar with all refrigerants and work with ventilation, control technology and heating systems. That is, everything around a cooling machine,” says William Giorgi.

Assignments range from installing and commissioning new cooling systems in various spaces to modernizing and streamlining existing cooling systems. A major customer is Wellspect HealthCare in Gothenburg, which offers proprietary products and services in incontinence care. The assignment there consists of technical property management with a focus on cooling. William and his colleagues are responsible for maintaining the company’s cleanroom validation by ensuring the correct temperature, humidity and pressure are maintained in these environments.

Cooling for air treatment in cleanrooms
– “Our job is to ensure optimal cooling for air treatment processes through continuous, transparent monitoring and servicing of refrigerants, ventilation and humidification,” says William.

Kyl & Industriteknik also monitors the climate in a large warehouse where catheters are stored. Data loggers are deployed up at the ceiling and down at the floor in several different places to detect any temperature differences in the warehouse. The dataloggers are Celsicom T600s that store all temperature values in the cloud, which means that William can get the current values on his mobile at any time and quickly troubleshoot and fix any problem.

For the majority of other tasks, William uses manometer stands, sensors, air flow meters, multimeters and other measuring instruments from Testo. He appreciates the quality and simplicity of, for example, the testo 558s pressure gauge rack.

Durable, smart measuring instruments
– It works flawlessly in all situations – even outdoors in really tough weather conditions. I also like the ability to connect wireless SmartProbes sensors to the manometer stand. In other words, the measuring equipment makes things a lot easier and allows me to do all the cooling jobs more efficiently. Another thing I like is that Testo continuously comes up with updates that improve the measuring instruments, says William and adds:

– I also appreciate the proximity to Nordtec. If I have a technical question, I can always reach a product expert and get a quick answer. They know the ropes. From time to time I also get to test new tools that might be interesting to acquire in the future. For example, I was able to test the testo 560i digital refrigerant scale, which offers a very smart solution for charging refrigerant.

A lot is happening in the field of refrigeration, which means that William and his colleagues must constantly keep their eyes open for new regulations and new refrigeration technology. An amended F-Gas Regulation, which aims to phase out fluorinated greenhouse gases, is driving the shift to natural refrigerants. The aim is to reduce emissions of carbon dioxide equivalent, which is a term for gases that contribute to the greenhouse effect and global warming.

“Exciting transition journey”
A significant part of the job at Wellspect HealthCare is to jointly drive the transition to environmentally friendly refrigeration technology by replacing the refrigeration plant with ammonia. Of course, William is happy about this change because it creates more work for him and his colleagues in the industry.

– As we move to natural refrigerants such as ammonia, hydrocarbons and carbon dioxide, there are additional safety requirements as some of these refrigerants are flammable and toxic,” says William, concluding:

– We have started an exciting transition towards more sustainable cooling systems and environmentally friendly refrigerants.
