Finned tube heat exchangerAerofin® FNF, ANF

air/air

5/8" OD tube non-freeze steam coil for heating Type FNF steam coils are designed for freezing air, heating applications. The non-freeze design is accomplished with inner-distributing tubes (tube within a tube construction). Outer finned tubes are 5/8” OD. Tubes are pitched in two directions within the casing for positive condensate drainage in either horizontal airflow or vertical airflow mounting positions. Type FNF coils are available with 1 or 2 rows and are typically used for applications with low to moderate steam condensate loads. This coil type falls within the scope of ARI standard 410 Certified Ratings.
