The oil cooler is a liquid / liquid cooler and uses refrigerant (in the tubes) to cool the oil that heats up due to the heat generated by the compressor.
Because it was a mobile unit, an efficient and compact device had to be designed and due to the fact that the temperature approach between the oil and the coolant was very small, an F-shell with a horizontal longitudinal bulkhead was chosen. the torso. This creates a 2-pass shell and through the use of u-tubes pure countercurrent and maximum LMTD are realized. Because Robox carries out all activities in-house, providing all necessary data could fully support the customer in obtaining permission for admission to the Belarusian market.
The oil cooler has a 2-pass shell, removable u-bundle with horizontal longitudinal bulkhead in the hull and a removable bonnet type header, TEMA type BFU 324/2700. Everything completely executed in C-steel. Designed and built according to PED cat. II / Mod.A1 and ASME VIII Div.1
