MATCH YOUR NEEDS TO PROSEMI

By partnering with us, you gain access to robust heat exchanger solutions engineered for demanding industrial environments. Our brazed and welded plate technologies are designed to deliver efficient heat transfer, compact footprints, and long-term operational reliability. From system selection and technical consultation to integration and full-scale operation, we support your thermal performance goals at every stage.

Core Performance Parameters and Selection Fundamentals for Plate Heat Exchangers

1. Heat Load (Q)

The client’s core requirement (kW, BTU/h).

  • Calculated based on flow rate, specific heat capacity, and temperature difference
  • The starting point for all heat exchanger design calculations

2. Flow Rate (ṁ)

Volumetric or mass flow rate of hot and cold fluids.

  • Directly influences plate count and heat transfer area
  • Affects channel velocity and overall process design

3. Temperature (T)

Inlet and outlet temperatures of both fluids.

  • Used to calculate the logarithmic mean temperature difference (ΔTlm)
  • ΔTlm represents the driving force for heat transfer

Higher ΔTlm requires less heat exchange area.

4. Allowable Pressure Drop (ΔP)

Pressure loss tolerance of the client’s system (bar, psi).

  • One of the most critical constraints for selection
  • Low ΔP may result in poor heat transfer performance
  • High ΔP may exceed pump capacity or increase energy consumption

5. Overall Heat Transfer Coefficient (K / U)

Measures heat transfer efficiency (W/m²·K).

  • Significantly higher than shell-and-tube heat exchangers
  • Influenced by flow velocity, fluid properties, plate corrugation, and fouling

6. Fouling Factor (Rf)

Safety margin for performance degradation (m²·K/W).

  • Increases required heat transfer area and cost
  • Varies with fluid type: cooling water, river water, oil, steam, etc.

Fouling assumptions should always be confirmed with the client.

7. Design Pressure & Temperature

Maximum operating limits the equipment can safely withstand.

  • Determines plate thickness and frame strength
  • Critical for gasket material selection

8. Medium Properties

Extremely critical for correct material and model selection.

  • Chemical composition, concentration, viscosity
  • Corrosiveness (pH, chloride content)
  • Presence of particles or fibres
  • Phase changes such as condensation or evaporation

These factors directly determine plate material, gasket type, and plate design.
