The finned-tube coil is the heart of every TECS unit and it is made in our own factory. PLC-controlled fin lines stamp the aluminium fins from coil stock, hairpin benders form the copper tubes, and automatic tube expanders fix the tubes into the fins to give the metal-to-metal contact the thermal design relies on. Headers and tube ends are machined on CNC equipment, so every coil of a series is the same coil.
Casings, fan plates, support legs and frames are cut and formed on turret punch presses, brake presses and a shear press, and pipework is bent on CNC pipe benders. Fans, guards, expansion tanks, junction boxes and connections are assembled on the finished unit, and every circuit is pressure tested before the fans are fitted.
Overhead cranes and the assembly area allow units up to 13 m long to be built, tested and packed as one piece for road or sea transport.
Quality
Every circuit is pressure tested, fans and electrical equipment are function tested, and the records are delivered with the unit. Performance and acoustic verification are carried out where the project specifies them.
