Plate Heat Exchanger · Heat Exchangers
Sondex S-8 500kW FW cooling is a gasketed plate heat exchanger. It is installed in an engine-room cooling, heating or process circuit between two separate fluid systems. Its purpose is to transfer heat efficiently between fluids while keeping the circuits separated. A corrugated plate pack provides the heat-transfer surface, with a permanently brazed core used in brazed units and an openable gasketed frame used in gasketed units. The exact model designation and the listed surface or duty information distinguish plate size, material and thermal selection from neighboring exchangers; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Trend inlet and outlet temperatures and pressure drop to identify fouling. Inspect frame or external connections and visible sealing areas for leakage or distortion. Clean heat-transfer surfaces using methods compatible with plate and sealing materials. 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.
Keep model-correct gaskets or connection seals, selected spare plates for openable units, filters and manufacturer-recommended service parts. Brazed units are normally replaced as an assembly after an internal structural leak. Verify materials and dimensions against the exact serial number.
