We have hundreds of exchangers in stock

Online BPHE calculator

Heat exchangers do not come with fixed capacity ratings (kW) as capacity depends on specific project parameters, including temperatures and media. You can learn more in our article on heat load.

Our online selection tool is a simplified version of the SSP SWEP software. By entering the required heat load and design temperatures, the tool generates a list of suitable heat exchangers. It can also be used to estimate BPHE models for cooling applications.

This online tool provides a simplified calculation for heat exchanger selection, primarily for heating applications. It is a streamlined version of the original SWEP SSP software. Inputs: required heat load and designed temperatures. Output: estimated number of plates for the selected model. The tool can also be used to estimate a brazed plate heat exchanger (BPHE) model for cooling applications. An online calculator for oil coolers is available on the gasketed heat exchangers page.

• Media: water, glycol (ethylene glycol 40%), oil (ISO VG 46).
• For more accurate results, use the Google Chrome browser on a PC to access the online calculator.
• The output (i.e. BPHE model and required number of plates) is indicative and does not serve as a design.
• The online program operates with a basic range of heat exchangers and selects models that are commonly available in stock.
• Pressure drop of 10 kPa is equivalent to 1 meter of water column.

Inputs for calculation

We can design a plate heat exchanger tailored to your project based on your input parameters. Manufacturers' software calculates the heat exchange area from the provided inputs (capacity, media, temperature), then designs exchangers of various types (e.g., SWEP B8TH, B26H, B120), each available with different plate counts (10, 20, 30, etc.). The software sorts the calculated options by price and pressure losses to select the most suitable model for your needs.

To calculate the appropriate size of a plate heat exchanger, please provide us with the following information:

• transmitted power (capacity) (e.g., 150 kW);
• media (e.g., glycol, wort, oil, steam);
• primary circuit temperatures T1 and T2 (e. g. 90 and 70 °C);
• secondary circuit temperatures T3 and T4 (e. g. 60 and 80 °C);
• alternatively, flow rate (q1) instead of any of the temperatures T1, T2;
• maximum allowable pressure losses dp1, dp2 (eg 50 kPa).

Since the SWEP calculation program is not freely available, you can send us your input parameters, and we will provide you with a custom heat exchanger design.
