Among these processes, the workshop is responsible for cleaning new cast iron engine cylinder heads which can reach up to 250 kg and 1.20 m long before installing them, and which arrive covered with a very heavy storage grease. thick protecting them from corrosion. To do this successfully, operators had to clean the parts manually with a brush using acetone before rinsing them with a Karcher, a process that could take 2-3 hours in total.
Marine diesel engine parts such as coolers and plate heat exchangers which are used to cool fluids to ensure their proper functioning must also be regularly descaled. Scale deposits rush into the internal cavities and part tubes, which further complicates the cleaning process which consisted of soaking them in a hydrochloric acid bath for 30 minutes to an hour then brushing them manually, a process that could last up to 4 hours.
At Eneria, ensuring the safety and preserving the health of employees are major objectives. The company is also involved in protecting the environment by implementing concrete actions to reduce the ecological impact of its activities and that of its customers. This is why the company turned to Safetykleen to find cleaning solutions that meet all of their challenges.
After a complete diagnosis of Eneria’s problems, two automatic cleaning solutions were chosen and implemented in the workshop, each dedicated to its cleaning problem.
For engine heads, it is the automatic spray machine Aquakleen Automatic which was chosen, with an aqueous-based solution that ensures optimal cleaning without risk to the health and safety of operators thanks to a closed circuit but also without risk for the environment.
This automated parts washer allows the simultaneous cleaning of several parts, even large ones, in a one hour cycle, while freeing the Eneria teams by programming the duration and temperature of the cycles as needed. Its motorized rotating basket will turn the parts to allow deep cleaning, even the most difficult to reach areas. The machine is also equipped with excellent insulation to reduce its power consumption.
For marine diesel engine parts, our teams turned to the Sonickleen ultrasonic cleaner to efficiently and quickly descale all areas of the parts. The innovative ultrasonic cleaning technology and a detergent solution without VOCs (Volatile Organic Compounds) chosen allow rapid and targeted elimination of tartar, and compensate for the immersive acid bath solution. Its process also does not require any intervention from operators in order to let them concentrate on their activities.
