Our FLFA semi-welded plate heat exchangers are the primary choice for applications that require corrosive media or high pressure. We customize each heat exchanger to your specifications and provide a durable solution to withstand extreme conditions and minimize the risk of chemicals or refrigerants.
Semi-welded plate heat exchanger
Our FLFA semi-welded plate heat exchangers are ideal for ammonia applications and can handle most refrigerants easily. Primarily used in the air conditioning and refrigeration industries, they are typically installed as evaporators, condensers or oil coolers, but their versatility means they can be easily configured for use in other industries and applications, such as chemical processing.
With our solutions, you can safely operate dangerous, aggressive media, high pressures or extreme temperatures, which are not suitable for conventional rubber seal heat exchangers.
What does this mean for you?
Our FLFA Semi-Welded Series eliminates off-the-shelf heat transfer solutions and offers custom heat exchangers for your personal applications. Enjoy a service-friendly, semi-welded plate heat exchanger that is easy to install and provides efficient thermal performance.
In order to improve safety, the semi-welded product range uses box-type plate set technology instead of ordinary plates. The non-hazardous medium in each plate group flows on the side of the gasket and the dangerous medium flows in the middle of the welded plate. The combination of alternating gaskets and welding processes ensures that the media does not mix.
There is a custom, damage-resistant annular gasket on the welded side. Our semi-welded plate heat exchangers have a long product life and provide safe, leak-free operation, greatly reducing the exposed gasket area.
Our extensive experience and extensive process knowledge enable us to avoid the common pitfalls of complex applications and provide reliable, high performance heat exchangers.
Features and benefits
High efficiency means that high performance requires fewer plates, thus reducing footprint. The lack of plates also reduces the cost per heat exchanger as an additional bonus.
Designed for use with a small amount of potentially hazardous media, the FLFA Semi-Welding Series is a safe and responsible option.
Unique gasket system for high working pressure and vacuum applications. The gasket groove keeps the gasket secure and prevents inconsistencies in the package during assembly and operation.
