Plate Heat Exchanger · Heat Exchangers
Hisaka UX-40 Series is a gasketed plate heat exchanger. It is normally installed in an engine-room cooling, heating or process circuit between two separate fluid systems. Its purpose is to transfer heat efficiently across corrugated plates while keeping the two media separated. A gasketed plate pack can normally be opened for cleaning and plate replacement, which distinguishes it from permanently brazed plate units. The exact model designation and listed surface or duty information distinguish frame size, plate geometry and installed duty from neighboring exchangers; refer to manufacturer documentation for the exact figures.
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 the frame, tightening arrangement, port connections and visible gasket edges for leakage or distortion. Clean plates using methods compatible with plate and gasket materials and inspect individual plates for corrosion, deformation or cracking when opened. Confirm plate order and orientation during reassembly. Support connected piping independently so nozzle loads are not transferred into the frame. Refer to the manufacturer documentation for the exact tightening dimension, gasket material, cleaning chemistry and pressure-test criteria.
Keep a set of model-correct plate gaskets, selected spare plates, port gaskets and any special frame sealing components recommended by the manufacturer. For critical coolers, enough plates and gaskets to recover from localized damage can reduce downtime. Verify materials and plate pattern against the exact serial number.
