Cuatro-20 Control Systems was born out of the lack of specialists in PLC-based control systems in a highly industrialized city like Huelva, to provide services both here and worldwide. With over a decade of experience in the naval and industrial sectors, our staff possesses excellent technical qualifications that endorse them to undertake projects related to:
- System integration.
- Design and construction of control panels.
- PLC, HMI, and SCADA programming.
- Industrial instrumentation.
- Migration of obsolete control systems.
- Repair of electronic equipment.
- Repair of frequency converters and soft starters.

Additionally, we provide technical assistance services worldwide, carrying out maintenance, installation, repair, and/or improvement works on naval equipment such as: bilge separators, oil meters, boiler control systems, incinerator control systems, power plant control systems, UMS alarm systems, refrigeration plant control systems, and much more. 

Furthermore, our facilities are equipped with the necessary instrumentation, knowledge, and experience to repair all types of electronic equipment, and even to study and manufacture obsolete electronic boards that are not available in the market.
