Refurbishment of a CAT C32 plate heat exchanger for Spliethoff

For Spliethoff, we received a CAT C32 plate heat exchanger at our workshop for maintenance. The unit consists of 61 titanium plates and was delivered complete with frame. Before we start a refurbishment, we first determine the condition of the heat exchanger. We look at contamination, the condition of the plates and seals, and check […]

Overhaul of a Hisaka PHE for the MV Challenge Prime

A plate heat exchanger plays a key role in the on-board cooling system. Contamination between the plates and wear on the gaskets can affect the operation of the PHE and make regular maintenance necessary. In February 2026, we received a Hisaka plate heat exchanger from the MV Challenge Prime on behalf of EDR for a […]

Refurbishment, repair and recoating of 3 NRF box coolers for the MV Bergensfjord

For the MV Bergensfjord, we received three NRF box coolers with heavy marine fouling. Large sections of the tube bundles were covered with mussels, shells, sludge and other organic growth. This may not only have restricted heat transfer, but also made it difficult to assess the actual technical condition of the cooling tubes. We therefore […]

Boxcooler refurbishment voor MV Flying Dutchman

A box cooler is a critical component of a vessel’s cooling system. Day after day, the unit is exposed to water, contamination, and corrosive influences. Without regular maintenance, not only does cooling efficiency decrease, but the risk of failures and unplanned repairs also increases. At Blue Orange, we frequently encounter box coolers that are still […]

Overhaul of plate heat exchanger for industrial application

Within industrial processes, the reliability of plate heat exchangers is essential for stable and efficient operations. As a heat exchanger has been in operation longer, plate fouling and gasket wear can lead to loss of efficiency and increased risk of failure. For this project, one industrial plate heat exchanger with a plate pack of 37 […]

Overhaul & recoating of 8 box coolers in the Maritime Sector

Eight NRF box coolers were delivered to a marine vessel for cleaning, pressure testing and complete overhaul. The pre-service reports indicated that the coolers were severely fouled: heavy fouling from long-term exposure to seawater, multiple spots of hard limestone deposits and incipient leaks. The documentation states, among other things: “very hard limescale,” “already 2 leaking […]
