What parameters are required to purchase plate heat exchangers and air coolers?

Didn’t the design institute give you the design data sheet?

When purchasing plate heat exchangers and air coolers, a series of key parameters must be provided to help select or design the most suitable equipment for your specific application. These parameters usually include, but are not limited to, the following: **For plate heat exchangers:** 1. Fluid type: It is necessary to know the type of fluids flowing on both sides of the heat exchanger, such as water, oil, acids, alkalis, etc. 2. Fluid temperature: includes inlet and outlet temperatures. 3. Fluid pressure: includes inlet and outlet pressure. 4. Fluid flow rate: or heat transfer requirement. 5. Design pressure and design temperature. 6. pH value of the working medium. 7. Material requirements: The material requirements for heat exchanger plates and gaskets, such as stainless steel, titanium, Hastelloy, etc. 8. Connection method and size: such as clamp, thread, flange, etc. 9. Any special requirements, such as anti-corrosion requirements. **For air coolers: ** 1. Fluid type: The type of medium to be cooled. 2. Fluid inlet and outlet temperatures: Determine the required cooling capacity. 3. Fluid flow rate: Affects the size and configuration of the heat exchanger. 4. Evaporation temperature and condensation temperature: For refrigeration applications. 5. Design pressure and operating pressure. 6. Environmental conditions: such as ambient temperature, humidity, etc. 7. Cooling medium: Usually air, but information on specific humidity or purity levels may be required. 8. Heat exchange area and fan configuration: including the number of fans, power, and air volume. 9. Material requirements: Requirements for materials used in heat exchange pipes, finned plates, frames, etc. 10. Noise level limits: especially in places with strict restrictions. NB/T 47004 and NB/T 47007 are Chinese standards that specify the design and manufacturing requirements for plate heat exchangers and steel air coolers, respectively. These standards provide detailed specifications for sorting, manufacturing, and testing, but usually do not offer standard parameter tables. You can contact the manufacturer or supplier of the heat exchanger; they usually provide standard forms or configuration sheets that you can use to fill in the required parameters based on your application needs. If you need a specific table template, you may need to contact the heat exchanger manufacturer or supplier directly, or search in industry-related technical documents and communication platforms. Since these table templates often need to be customized according to actual design and manufacturing requirements, there are usually no standard tables that can be used universally. .

I’m from a design institute; what do I need to provide?

What kind of crappy design institute is this? They design something without even knowing the design parameters for the equipment they’re purchasing – absolute garbage!
