Italian excellence in the marine air conditioning sector

zero vibrations zero noise zero condensation
easy installation zero mould 100% made in Italy

Climate control, both heating and cooling, in the nautical sector, presents an ongoing challenge for improvement. Combining functionality, ease of installation, compact size, noiseless operation, power and quality is not an easy task, but WEKER has already risen to the challenge. Today Weker offers a range of products which not only constitute the last word in comfort, but also succeed in satisfying all kinds of clients. 7,000 to 1,000,000 BTU is a range which few firms can take on, and Weker has done it magnificently, with its usual unbeatable style. The next step is to become leader in the sector. Whatever your criteria, we are here to design a solution based on your requirements.


These systems feature a unit known as a chiller, usually placed in the engine room and connected to fan coils (ventilating units) located in the cabins to be heated or cooled. The Chiller series of air conditioning and heating systems are built using materials especially suited to marine use; they are encased in stainless steel panels which not only protect the components but also guarantee more noiseless operation. All the systems, fitted with reverse cycle inverters, are complete with seawater/gas condensers in cupronickel, load-bearing structure in stainless steel and hermetic rotary or scroll compressors. With the Chiller system, the ventilating units mean that each cabin can have the desired temperature. With capacities from 12,000 to 250,000 BTU, these are the smallest and most powerful systems in the world.
