05 · FAQ
Plate heat exchanger questions
Practical answers covering selection, design ranges, materials and common maintenance issues.
How do I select the right plate heat exchanger?
Selection starts with the actual duty: hot- and cold-side inlet/outlet temperatures, flow rates, media properties, pressure, allowable pressure drop and connection requirements.
What pressure range can a plate heat exchanger handle?
Typical ranges are up to 2.5 MPa for gasketed units, 4.0 MPa for brazed units, 6.0 MPa for fully welded units and 2.5 MPa for semi-welded units. Final limits depend on model and material.
What temperature range is available?
Typical ranges are 0–180°C for gasketed units, 0–200°C for brazed units, 0–350°C for fully welded units and 0–180°C for semi-welded units.
Which plate materials are commonly available?
Common materials include 304 and 316L stainless steel, titanium, Hastelloy and 254SMO. Selection depends on corrosion, temperature and hygienic requirements.
Which gasket materials are commonly available?
Common options include EPDM, NBR, HNBR and FKM, plus fluorinated, PTFE and silicone solutions for specific duties.
What causes internal or external leakage?
External leakage is commonly linked to aged, damaged or incorrectly compressed gaskets. Internal leakage may indicate cracked or damaged plates.
What should I do if heat-transfer performance drops?
The usual causes are fouling or blockage between plate channels, off-design flow or incorrect piping. Verify operating data, then inspect and clean the plate pack.
