An SRL finned tube radiator is an industrial air-heating unit that uses steam to rapidly raise air temperatures. It features steel or copper base tubes wrapped with aluminum fins to maximize surface area for efficient heat transfer. These coils are widely utilized in factory drying systems, greenhouses, and large manufacturing facilities.
How the SRL Design Works
The SRL system operates using forced or natural convection. As steam flows through the inner tubes, heat transfers through the tube wall to the outer fins, which quickly dissipate that heat into the surrounding air.
Key Technical Specifications
Heat Medium: Steam (or hot water)
Operating Pressure: Typically supports steam pressures up to 0.3 to 2.6 MPa (depending on the specific model and manufacturer)
Materials: Commonly constructed with a carbon steel frame and a combination of steel-aluminum heat radiating pipes.
Rows: Available in configurations of 2 to 3 rows depending on the required air temperature and capacity.
Advantages
High Efficiency: The aluminum fins provide a massive surface area, vastly improving thermal conductivity and heating speed.
Durable: The tight, mechanical bonding or wrapping of the fins minimizes thermal resistance and prevents deformation over repeated hot/cold cycles.
Compact: It offers high heating capacity in a relatively small physical footprint.
