Onda S76 2000kW Central cooling

Onda Onda S76 2000kW Central cooling is identified in the source list as a brazed plate heat exchanger. It is normally installed or arranged in the engine-room cooling, heating or process circuit. Its purpose is to transfer heat between separate fluid circuits. The source record provides the existing record note 'Heat Exchangers, Central cooling'. The equipment is based on plate, brazed-plate or shell-and-tube heat-transfer surfaces and connections. The exact model designation distinguishes the installed configuration from neighboring variants in the same category; refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

●Heat-transfer surface fouling caused by scale, sludge or biological deposits, resulting in reduced thermal performance and increased pressure drop
●Seal, gasket, braze or tube leakage caused by wear, corrosion or thermal cycling, resulting in external leakage or cross-contamination
●Plate or tube corrosion caused by incompatible fluid chemistry, resulting in pinholes and contamination between circuits
●Blocked flow passages caused by debris or deposits, resulting in uneven flow and abnormal differential pressure
●Frame, cover or connection problems caused by incorrect assembly or piping stress, resulting in leakage and mechanical distortion

Service & Maintenance

Trend inlet and outlet temperatures and pressure drop to identify fouling. Inspect frame or covers, port connections and visible sealing areas for leakage or distortion. Clean heat-transfer surfaces using methods compatible with installed materials and deposits. Investigate any evidence of cross-contamination with an approved leak or pressure test. Support connected piping independently so nozzle loads are not transferred into the exchanger. Refer to the manufacturer documentation for the exact figure for tightening, cleaning, pressure-test and repair criteria.

Replacement Parts

Keep model-correct gaskets or cover seals, selected spare plates or approved tube-repair materials as applicable, port seals and manufacturer-recommended corrosion-protection parts. Brazed units are normally replaced as an assembly after an internal structural leak.
