WELCO is a key supplier of small to medium series production of cooling compressors, as well as electrical motors used to drive fans, blowers and pumps based on in-house manufacturing capacities adapted to specific constraints.
Our products
Key advantages
Overall Weight: up to 30% lighter than mechanical solutions (belt-driven…)
Power range: high variability, electronically controlled
High Voltage: lower Current (amps) consumption
Unmatched Electrical Power to Cooling Power ratio
Maintenance free: no maintenance needed, replacing the unit if broken(sealed); no mechanical system to grease, control, attend to, fix, etc
Low Noise Emission

ELECTRIC MOTORS
Our motors are fully adapted and customized as per our customers’ needs and depending on the application or environment. We manufacture our motors in-house under our own design and characteristics which allows us to produce motors for specific applications with a very high reliability and perfect adaptation to various needs or requests such as wild frequencies, 400Hz, 115V-3phases-60Hz motors…

In-House Manufacturing of electrical motors
FANS / BLOWERS
We design and manufacture adapted electrical motor for your special fan and blowers requirements. You have a fan or blower design and are struggling to find a suitable motor due to specific constraints (frequency / voltage / power / size…): please consult us and we will work on a solution with you.
PUMPS
For specific applications (mission-critical with a very high level of reliability) or severe environments (aeronautics, space, naval), we can design, manufacture and refit electrical motors on existing OEM equipment for specific demands or requests. For example we recently replaced an existing electrical motor on a pump of a standard off-the-shelf dishwasher for a special demand on a civil aircraft.
Do not hesitate to send us your specific requirements (however special or demanding), our team of dedicated experts will analyze your needs and will be able to propose an adapted product based on our 40-year experience with ECS customers worldwide.
