ammonia plate heat exchanger

A plate heat exchanger for ammonia requires careful selection of plate materials, gaskets, and construction. Stainless steel ammonia plate heat exchangers and semi-welded plate heat exchangers are widely used in industrial refrigeration, including ammonia condensers, evaporators, ammonia glycol heat exchangers, and ammonia water heat exchangers. Depending on the operating conditions, an ammonia plate and frame heat exchanger may use 316 stainless steel plates with suitable NBR or CR gaskets. Applications range from food processing and cold storage to industrial cooling, ammonia production, and emerging NH₃ energy systems. This guide explains material compatibility, gasket selection, anhydrous ammonia heat exchanger considerations, and how to select the right ammonia heat exchanger for reliable operation.
