This type of heat exchanger uses a tubular structure where fluids exchange heat without mixing. It is better suited than plate heat exchangers to processes requiring high temperature/pressure, a risk of fouling, mechanical cleaning, or very large capacity.

Petrochemicals, power plants, metallurgy/shipbuilding, chemicals, HVAC, steam and condensate, energy recovery, pool heating, and oil cooling. Solutions up to 350°C are available for hygienic processes such as food and beverage and pharmaceuticals (with a CIP/SIP compatible design); for pool applications, we offer models from 15 to 1,750 kW.

The options for fixed tube sheet, U-tube, and floating head, baffle arrangement, and horizontal/vertical mounting are determined by the process fluids, temperature and pressure, water/chemical analysis, and permissible Δp. Materials are typically selected from ST37/ST35.8 (body), AISI 304/316(L), and copper/titanium (tubes) based on corrosion and mechanical requirements.

Depending on the model and process, each Ekin Endüstriyel heat exchanger undergoes a 72-hour hydrostatic test at 1.5 times its normal operating pressure before shipment. Compliance with standards such as ASME Sec. VIII-1, PED, and TEMA, as well as material and welding certificates, are provided as required by the project.

The use of an inlet filter is recommended. Depending on the degree of contamination, mechanical cleaning (inside the tube) or chemical cleaning (CIP) is performed. Warning signs such as an increase in differential pressure (Δp), a drop in fluid or outlet temperature, and vibrations should be monitored regularly; insulation should be replaced if necessary.
