Urgent help needed for heat exchange equipment!

Thread Content

Dear colleagues, due to project requirements, we are in urgent need of a heat exchanger at the moment. If any of you in this industry have a suitable heat exchanger, please get in touch with me. Thank you very much. The technical requirements for the heat exchanger are as follows: 1) It should be a gas-liquid heat exchanger, with inert gas on the gas side and an operating pressure of 25 bar; the liquid side should use normal cooling water, with a pressure of 5 bar sufficient. The heat exchange area should be ≥50㎡, and the heat transfer capacity should be ≥250 kW. The dimensions of the inlet and outlet ports on the gas side should be >DN100. 2) The heat exchanger must come with reports on its airtightness and strength tests. 3) The quality of the welds must be reliable; it’s advisable to have inspection reports available as well. 4) Since the project requires prompt use, it’s acceptable if there are significant deviations in the heat exchange area and heat transfer capacity. However, the operating pressure and the dimensions of the gas side inlet and outlet ports must be met. Those in the industry who are aware of suitable options can contact me; we can either rent or purchase such a heat exchanger.
