Maintenance, overhaul, and parts for air coolers.

Air coolers – service, overhaul, and parts

Rell supports companies worldwide with maintenance, overhaul, and parts for air coolers.

From charge air coolers and intercoolers to complete air cooler bundles – we provide inspection, cleaning, repair, and delivery of parts for various applications.

SERVICE & MAINTENANCE

Revision of complete bundles - Revision of complete coolers

Air coolers are widely used on the main and auxiliary engines of ships, as well as in CHP (combined heat and power) plants and industrial power plants. These coolers ensure efficient cooling of the intake air, allowing engines to perform optimally and reducing fuel consumption and emissions.

Due to pollution, corrosion, leaks, or damaged tubes, heat transfer can decrease. This often leads to higher engine temperatures, power loss, and an increased risk of malfunctions or unplanned downtime.

Rell supports shipping companies, shipyards, CHP plant operators, and industrial companies in the inspection, cleaning, repair, and complete overhaul of air coolers. Depending on the condition of the cooler, we can replace tubes, repair damages, perform pressure tests, and overhaul complete air coolers, among other services.

Besides air coolers, we also overhaul plate heat exchangers, Pipe bundles, coolers and other heat exchangers used in the maritime, industrial, and power generation sectors. This allows us to maintain complete cooling and heat exchanger systems from a single central point of contact.

Our activities are tailored to the application, operating conditions, and technical requirements of your installation, ensuring your heat exchanger can function reliably and efficiently again.

When is maintenance needed

When is maintenance required?

Air coolers play a significant role in the performance of marine engines, auxiliary engines, and CHP plants. Due to fouling, corrosion, or wear, heat transfer can decrease, leading to less efficient engine operation and an increased risk of failures.

Reduced cooling capacity
Increased pressure drop
Coolant or air leak
Corrosion or damage to tubes
Fin fouling
Higher intake air temperatures
Engine power loss

When these signs are recognized in a timely manner, larger repairs and unplanned downtime can often be prevented. Regular inspection, cleaning, and overhaul ensure the air cooler performs optimally and extend the lifespan of both the heat exchanger and the motor unit.

Rell supports customers worldwide with inspection, cleaning, repair, and overhaul of air coolers, tube bundles, and other heat exchangers for the maritime, industrial, and power generation sectors.
