SÜLZLE KOPF manufactures largest heat exchanger


over 900 welded tubes

SÜLZLE KOPF manufactures two tubular heat exchangers for HEIZA

The welding department has completed two large shell-and-tube heat exchangers for the customer Heiza-Werkstätten, a leading specialist in heat transfer and heat recovery, which will be transported by the customer to Russia by truck, partly as a special transport. There they will be integrated into a plant for the recovery of heat generated during the production of potato chips. The order is not an everyday order for SÜLZLE KOPF’s Welding Production department: it involved the largest heat exchangers ever manufactured by SÜLZLE KOPF. A heat exchanger made of carbon steel in horizontal design was delivered.

The heat exchanger with a diameter of 1,700 millimeters and a length of 7,500 millimeters has a tube bundle with over 800 welded-in tubes with a diameter of 42 millimeters.The weight is approx. 19 tons.

A heat exchanger was also supplied in vertical design and in the material combination carbon steel / stainless steel. The stainless steel tube bundle of the 2,500 millimeter diameter heat exchanger has almost 900 welded-in tubes with a diameter of 38 millimeters. This heat exchanger weighs approx. 17 tons.
