AlfaNova-52-90P
The Alfa Laval S.p.A. AlfaNova-52-90P is an AlfaNova fusion-bonded plate heat exchanger. AlfaNova units use corrugated stainless-steel plates bonded with Alfa Laval's fusion-bonding process, producing an all-stainless-steel heat-transfer path without conventional copper or nickel brazing material. This construction is intended for duties where material compatibility, cleanliness or resistance to aggressive media makes a conventional copper-brazed exchanger undesirable. The unit is compact and gasket-free, so the plate pack is not normally opened for onboard maintenance and cleaning is performed by suitable flushing or cleaning-in-place procedures. Neighbouring AlfaNova sizes and suffixes represent different configurations, but no plate count, duty or operating limit should be inferred from the supplied model string alone. The designation AlfaNova-52-90P identifies a specific AlfaNova fusion-bonded 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.

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.
