Kolmeks Ltd – Finnish pump and motor manufacturer
Reduced costs and improved reliability

The project

Headquartered in Turenki, Finland, and with factories also in Chuzhou, China, and Viljandi, Estonia, Kolmeks Ltd manufactures pumps and motors which are typically used in heating and cooling systems, in pressure boosting and, to an increasing extent, also in the process industry. Kolmeks saw the potential of integrating AC drives into the pump system.

The solution

VACON® 20 Cold Plate was integrated with Kolmeks' updated family of in-line pumps in a power range from 0.75 kW to 7.5 kW. Kolmeks also started a software development project to get the necessary multipump drive features for the small end of VS pumps.

We enjoyed fluent collaboration between Vacon's expert team, Kolmeks' R&D department and sub-suppliers. A teamwork of Chinese, Italian and Finnish experts in this case ensured a successful result. The transition to Danfoss Drives was smooth and the fluent collaboration has continued.

The result

Using AC drives to control pumps and pump systems significantly improves the controllability and energy efficiency of the whole pump system. The output, pressure and flow in the water piping system can be adjusted in relation to actual needs. This reduces energy consumption and stress on the electrical network and mechanical parts, extends the operating life of the pump, and improves operational reliability. Teamwork between Chinese, Italian and Finnish experts ensured a successful result.
