Most frequent findings

Internal contamination

Structural frame

2×

Observed condition: Inside the structural frame, sediment build-up and rust were found, a condition that could be associated with an insufficient coolant concentration in the water mix.
Technical risk: Low efficiency, internal damage to the radiator lines.

Dirt build-up in the core

Core

2×

Observed condition: Dirt build-up and contamination between the core rows.
Technical risk: Blocked air flow, overheating and loss of efficiency.
Recommended action: Deep cleaning with a method that does not deform the fins.
