Niche Slimline Coil Heat Exchangers

Reliable, Corrosion-Resistant Immersion Solutions

Niche Slimline Coil Heat Exchangers are engineered for metal finishing and chemical processing applications, offering superior performance and durability in harsh environments. These immersion heat exchangers are especially effective in batch and continuous steel pickling operations, where substandard materials often lead to corrosion and frequent maintenance. With Niche fluoropolymer tubing, corrosion and fouling are virtually eliminated, ensuring a long service life and reducing operational costs.

Available in standard FEP or proprietary Q-series tubing, Slimline Coils excel in both efficiency and performance, particularly in high-pressure and high-temperature applications. For steam heat processes, the Q-Series Slimline Coils avoid desuperheating, saving energy and optimizing productivity. Their role in metal processing helps lower acid consumption, cut down waste, and reduce the costs of spent pickle liquor disposal.
