Maxi size, minimal noise. The PME cooling towers supplied to CAMpreq, installed at a paper mill in central Sweden, combine appropriate design with high water flow rates and solutions to contain noise levels.Learn More
Industrial cooling towers for a steel processing plant in Sweden
MITA Cooling Technologies supplied two PMM open-loop towers for the Swedish multinational steel processing company SSAB: a few years later, we are receiving very positive feed-back regarding the technical solution and performance.
- Supply of large modular cooling towers
- High powers, easy maintenance
- Very positive customer feedback on the shared choice
- Type of interlocutor

1. Company and installation context
As SSAB‘s website explains, “The company is a leading manufacturer in the global market for advanced high-strength steels (AHSS) and hardened steels (Q & T), strip, plate, and tubular steels, as well as construction solutions. SSAB steels and services help make end products lighter and increase their strength and durability”.
SSAB, the company explains, has a cost-effective and flexible production system to produce about 8.8 million tons of steel per year. All with a focus on environmental sustainability as well.
The Swedish plants in Oxelösund are embedded in an integrated blast furnace process (from raw iron to steel blanks). At this plant, the outdated cooler needed to be replaced with a new one that would last and provide high performance for the entire process.
2. Proposed solution
The Swedish company CAM Preq, formerly known as C.A. Mörck, managed the project and relations with SSAB in Oxelösund:
- two industrial cooling towers type PMM C65;
- 9.3 MW to be disposed of;
- inlet and outlet water temperatures of 25.8 and 20°C respectively (with a wet bulb temperature of 18°C).
The PMM open-circuit tower is a modular system and suitable for medium- to large-scale plants. Fiberglass, of which all MITA industrial cooling towers are made, is also a durable material. Wide side accesses ensure easy inspection and maintenance.
Moreover, this is not the first supply of cooling towers, by MITA Cooling Technologies, for the steel industry. A significant project in Italy, for example, was the Rubiera Steelworks. In this case the customer’s different requirements, as to output water temperature and workload, called for the use of a smaller PME-E system (also open circuit).
3. Results obtained
One can assess the operational performance of the PMM industrial towers from the feed-back forwarded by SSAB to CAM Preq, as told by the Swedish supplier company itself: “The cooling towers are working perfectly so that continuous production operation is possible. Even the recent heat has not been a cause for concern: our engineering department, together with the supplier, have done a good job in system design and product selection”.
Cooling systems of this project
Foundries, steel mills, aluminum production lines: the plant managers of these industries require operational continuity, significant thermal jumps in cooling and cost containment for management and maintenance. Remote management platforms are an ally.
The mechanical industry includes the most diverse sectors, in addition to metal and plastic processing: compressors and test benches are significant examples. Required temperature differences and water quality vary greatly depending on the industry: evaporative cooling towers can be used, preferably open-circuit ones (with exchange packs for dirty or clean water depending on the context) and adiabatic coolers for consumption optimize.
The different phases of the industrial water treatment process require defined cooling temperatures in accordance with regulations. In this sector, it is preferable to use cooling towers with anti-clogging fill packs for industrial contaminated water.
MITA case studies
In 2019, MITA Cooling Technologies sold 4 PME-E open circuit cooling towers to a Swedish paper mill. The "Super Silent" version of the PME-E makes it possible to meet the customer's extraordinary low sound level requirements.Learn More
