ECOS®
Support And Maintenance Services For Stationary Energy Systems (CHP)
Our services for combined heat and power (CHP) plants and biogas facilities are channeled under our ECOS® business division.
We provide manufacturer-independent service for all common engine types, including both minor and major engine overhauls on-site and in our workshop. Our offering also includes the supply of spare and exchange parts, engine and plant optimization for emission reduction, and a wide range of additional services.
With over 90 years of experience in engine reconditioning, we service, overhaul, and optimize gas engines from various manufacturers used in CHP systems operating on natural gas, biogas, wood gas, landfill gas, or sewage gas.
In the event of operational issues, our mobile service technicians are available to provide prompt, on-site support. Component replacements and partial overhauls can also be carried out directly at your location – all without the need for a long term maintenance contract.
In addition to conducting the legally required annual emissions testing, we are happy to offer expert consultation on exhaust gas monitoring. We also provide retrofit solutions for your system upon request.
Full engine overhauls are carried out at our headquarters in Kiel-Wellsee. This includes inspection and refurbishment of individual engine blocks and housings, restoration of all engine components, and the reconditioning of turbochargers.
For your engine peripherals, we offer a wide range of services related to control systems, electrical engineering, and hydraulics. We support you with system upgrades, retrofitting, and optimization of switchgear, control and regulation systems, as well as engine monitoring.
