Technical Summary of Heat Exchanger Specifications

1. Specific Heat Transfer Parameters

The document provides specific heat transfer values expressed in kW/°C for various heat exchanger models. These values are essential for evaluating the thermal performance of each unit.

2. Flow Rate Ranges (Qhot and Qcold)

Two main flow rate parameters are indicated:

• Qhot (Hot fluid flow rate): Given in liters per minute (L/min), with standard ranges specified for different heat exchanger models.
• Qcold (Cold fluid flow rate): Also in L/min, with ranges varying by model:

• 40 to 230 L/min
• 20 to 140 L/min
• 12 to 75 L/min
• 8 to 46 L/min

3. Heat Exchanger Models and Ranges

The document lists multiple heat exchanger models, categorized under two ranges:

• Standard range: Models such as E135-564-4, E135-411-4, E135-283-4, E110-564-4, E110-330-4, E110-241-4, E083-411-4, E083-283-4, E083-196-4, E065-411-4, E065-241-4, E065-161-4.
• "E" range: Specific models within the standard range, possibly indicating enhanced or specialized versions.

4. Pressure Parameters

Two pressure values are mentioned:

• 250 mb (millibar)
• 2000 mb (millibar)

These likely correspond to operating or design pressures for the heat exchangers.

5. Thermal Performance Data

The document includes a table or chart with temperature differences (t_hot_in - t_cold_in) ranging from 10°C to 300°C, with corresponding heat transfer values (DPhot) for a 50% glycol mixture. The values range from 0.2 to 10 kW/°C, indicating the heat exchanger's capacity to transfer heat at various temperature differentials.

6. Notes and Recommendations

The guide values are subject to change without notice, emphasizing the need to contact the supplier or manufacturer to confirm selections based on specific thermal specifications.

7. Version and Date

The data corresponds to version 03.2018, indicating the last update of the specifications.

Critical Information Summary:

• Heat exchanger models are specified with corresponding flow rate ranges and pressure limits.
• Specific heat transfer coefficients vary with temperature difference and fluid composition (50% glycol).
• Users should verify current data with the manufacturer before final selection.
