Efficient technology for industry and refrigeration
Plate heat exchangers are essential components in refrigeration and many other industrial applications. They impress with their efficiency and versatility and are indispensable in many sectors. A plate heat exchanger is a specially designed device that transfers heat from one medium to another. Their compact design and high performance make them particularly suitable for industrial plants, the process industry, and in refrigeration technology.

With API Schmidt-Bretten’s plate heat exchangers, you benefit from innovative technology that combines efficiency, safety and flexibility.
Your advantages at a glance:
- Easy maintenance
The gasket side can be inspected and cleaned as with conventional gasketed plate heat exchangers – uncomplicated and time-saving. - Reduced risk of leakage
Thanks to the ring seal, the seal length is reduced to 20%, reducing the risk of leakage by an impressive 95%. - High degree of flexibility
The modular design allows for easy expansion or modification. Existing gasketed plate heat exchangers can be converted to semi-welded systems. - Fast return on investment (ROI)
No spare parts required on the welded side – this saves costs and significantly reduces downtime. - Cost efficient
Lower costs are required in comparison with purely gasketed plate heat exchangers. Options with FKM or PTFE gaskets offer additional cost-efficiency.
Advanced technology with SIGMADUAL plate heat exchangers
The SIGMADUAL semi-welded plate heat exchangers from API Schmidt-Bretten utilize state-of-the-art laser welding technologies, which guarantee the highest precision and reliability in plate processing.
Special features of laser welding technology:
- Product-side sealing:
Sealing is achieved by precise laser welding around the flow channel and the openings. High-quality elastomers such as nitrile, EPDM, FPM, or PTFE-coated elastomers are also used. - Service-side sealing:
On the service side, elastomers seal the flow channel, while the openings are also laser-welded.
Flexibilität durch modularen Aufbau
Ein großer Vorteil der SIGMADUAL-Plattenwärmetauscher ist ihr modularer Aufbau. Ähnlich wie bei gedichteten Plattenwärmetauschern können Module einfach ausgetauscht oder ergänzt werden. Dies ermöglicht eine schnelle Anpassung an veränderte Betriebsbedingungen und sorgt für maximale Flexibilität.
Höchste Betriebssicherheit durch doppelte Schweißnähte
Eine doppelte Schweißnaht an den Durchtritten der Wärmetauscherplatten sorgt für eine verbesserte Betriebssicherheit. Diese Konstruktion schützt effektiv vor Leckagen und ermöglicht eine sichere Produkttrennung – ein wichtiger Faktor in sensiblen industriellen Anwendungen.
