Koka's story


Kalevi Kariluoma, the founder of Koka, introduced plastic water traps to Finland

Koka Oy was established in the late 1960s when Kalevi Kariluoma who had worked in HVAC companies all his career, saw great potential in a plastic water trap for washing sinks manufactured by a German company. Until then, all water traps on the market were made of cast iron or brass. Kalevi’s lack of language skills or busy day job did not prevent him from starting an import business.


The plastic Akseli water trap became the market leader

Plastic was a revolutionary material in the water trap market, and it took effort to make customers and different user groups understand its benefits. In those days, there was no such thing as type approval certificates, let alone EU certificates. Despite this, the plastic Akseli water trap soon gained fame as the only plastic option on the market for a long time and the market leader for many years.


Several innovative products were developed for the market together with partners

During the 1980s, Koka Oy and its partners developed several innovative products for the Finnish market in a number of product groups. The company’s starting point has always been to provide most functional and advanced solutions for users.


Partnership with B-Meters

Cooperation with B-Meters began in the 1990s, with Koka Oy becoming an authorised representative in Finland.


Respected expert in water metering - Annual sales of more than 100,000 units in Finland

During the close cooperation with B-Meters over the decades, both parties have grown to become leaders in their fields and valued experts in water metering. B-Meters’ annual production of more than 2.5 million units globally is a significant amount, as are Koka’s annual sales of more than 100,000 units in Finland. The companies have achieved this position as a result of successful product development and long-term work as well as investments in customer service. The role of a pioneer is in our company’s DNA. We have always been among the first to adopt new technologies while still respecting traditions.
