DYNAMIC ENGINEERS introduces a range of Air Heat transfer Coils and heat exchanger Coils for Oil cooling, Refrigerant cooling, water cooling in air cooled condenser and evaporator applications.
Copper Tubes – The best quality imported 10mm, 13mm, 16mm OD Copper Tubes in level wound coils are used to ensure coils with the minimum number of joints by forming Hair pin bends as well as to ensure a uniform wall thickness that eliminates embarrassing & expensive leaks after installation. Tubes are staggered in the path of air flow for better heat transfer efficiency.
RETURN BENDS
They are die-formed from thick walled tubing that is heavier than the standard tubing used in the rest of the coil. This provides the toughness & durability required in the most vital part of the coil.
HEADERS
Inlet & Outlet headers are constructed of heavy wall copper pipe with shoulders formed at each brazed connection to the 13 mm,16mm tube in the coil. This header intruded with special tooling provides the strength to the brazed joint that eliminates another source of leak during transit & installation.
Mechanical Tube Expansion
Tubes are mechanically expanded for an optimum bond between Tube and Fin. This positive & controlled expansion procedure provides a clean, smooth inner tube surface for a low water pressure drop & guarantees uniform heat transfer between Tube & Fin.
PRESSURE TESTING
Each coil is pressure tested after manufacture by air under water at 350 psi for water application & 400 psi for air cooled condenser application using R-22.
