Cooling towers and cooling tower systems from Wesel
M-CTI Mumme Cooling Tower International GmbH is an owner-managed manufacturer of cooling towers based in Wesel, with around 25 years of experience in professional cooling tower systems. Sourced mainly from in-house production, the company supplies all proven and innovative wet cooling tower designs – from small to maxi versions – as well as their components and spare parts. The portfolio includes standard cooling towers, cell cooling towers and natural draft cooling towers in GRP, wood and concrete versions. In addition to manufacturing, M-CTI offers the construction, refurbishment and extension of existing cooling systems, including installation of noise protection components. The cooling tower service covers maintenance and upkeep, analysis and performance optimisation using special measuring methods, and spare parts supply; rental cooling towers are also offered. In the design and development area, design plans and technical drawings are produced using modern 2D and 3D CAD programs. The cooling towers are used, among other things, in the chemical, mineral oil and petrochemical industries, in the steel and aluminium sector, and in the energy industry.

Quality and service
The condition of the cooling systems is analysed using special measuring methods; parameters such as water distribution, temperature, power consumption, water drift, vibrations and machine noise are checked and regulated. Service contracts for regular maintenance ensure the performance and service life of the systems.
