FAQ
How long is the lead time for a plate heat exchanger?
For plate heat exchangers, the lead time typically averages 20 days due to the custom manufacturing based on the usage and flow rate. For urgent requests, the lead time can be less than 10 days, while mass production or rare metal manufacturing can take 90 to 150 days. (Lead times may vary depending on factory workload.)
Can the unit price of the heat exchanger be determined just by knowing the heat transfer amount?
Even with the same heat transfer amount (e.g., 100,000 kcal/hr), the model and heat transfer area (number of plates) of the heat exchanger will vary depending on conditions such as LMTD (Log Mean Temperature Difference) and DELTA.T (Temperature Change), making it impossible to determine the unit price solely based on the heat transfer amount. However, if the heat exchanger is used for a specific purpose (e.g., for hot water supply, heating), we can provide a quick quote due to the numerous case studies we have.
What is the maintenance interval?
The internal fluid of the heat exchanger can cause the heat transfer efficiency to decrease due to scale (e.g., lime, foreign substances, dust). Even for the same type of heat exchanger, the maintenance interval will vary depending on the operating environment and water quality. The best way to determine the maintenance interval is to check for an increase of more than 0.3 bar in the inlet/outlet pressure drop or a decrease in heat transfer efficiency, which indicates that maintenance should be performed.
