CBM76-180P

The Alfa Laval S.p.A. CBM76-180P is a compact marine-oriented brazed plate heat exchanger in the Alfa Laval CBM family. It transfers heat through corrugated metal plates that are permanently bonded into a gasket-free plate pack, allowing a small footprint compared with many conventional shell-and-tube arrangements. The CBM line is specifically positioned for marine heating and cooling duties and is commonly integrated into engine-room and cargo-support systems. Unlike a gasketed plate-and-frame exchanger, the bonded plate pack is not dismantled onboard for routine plate or gasket replacement; cleaning is normally performed by flushing or an approved cleaning-in-place method. Neighbouring model numbers and suffixes within the family distinguish physical or application configurations, but no capacity or plate count should be inferred solely from the model name. The designation CBM76-180P identifies a specific CBM marine brazed plate heat exchanger configuration in the supplied equipment list. Exact capacity, pressure and temperature limits, materials, connection details and internal configuration must be verified from the unit nameplate and manufacturer documentation; refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Fouling or scaling inside the narrow plate channels reduces heat-transfer performance and increases pressure drop
Blocked strainers or restricted upstream piping reduce flow and produce abnormal outlet temperatures
Corrosion, erosion or fatigue damage to the bonded plate pack can cause internal cross-contamination between circuits
External leakage at connections caused by damaged joints, vibration or piping loads produces visible fluid loss
Freezing, thermal shock or operation outside the approved pressure and temperature envelope can damage the plate pack and lead to leakage

Service & Maintenance

Trend inlet and outlet temperatures and pressures to identify gradual loss of thermal performance. Inspect the external plate pack, connections and supports for leakage, corrosion, vibration damage and excessive piping loads. Maintain upstream strainers and system cleanliness, and use only cleaning-in-place procedures compatible with the installed materials. Any indication of cross-contamination requires prompt investigation because the bonded plate pack is not normally opened for onboard repair; refer to the manufacturer documentation for test limits and cleaning criteria.

Replacement Parts

Because the bonded plate pack is a sealed assembly, the principal strategic spare is a correctly specified replacement heat exchanger where redundancy and trading pattern justify carrying one. Also consider connection seals, strainer elements, isolation-valve service kits and approved cleaning consumables. A replacement unit must match the original materials, connections, duty and approval requirements.
