Revotec’s cooling system for Classic cars.

Many classic cars only have a belt driven cooling fan. This vital cooling mechanism is old-fashioned and makes the cars prone to over-heating, especially while queuing in traffic with the engine idling. Revotec, however, are able to solve this problem by making an electronic controlled fan cooling system which can be fitted to these cars allowing the radiator to be cooled, in all conditions.

Carrs’ role in this process is welding the sensor housing, called a tube insert (pictured below), for Pace UK Ltd. This sensor is used to detect the temperature of the water pumping through the hose determining whether or not to start the fan. For their function, it is vital that these parts are thin to be able to react to the temperature quickly and efficiently. However, being thin makes the parts vulnerable to over heating in TIG welding, therefore laser welding is the best option for the job. The tube insert, a 5000 grade of aluminium, is welded with a filler wire to make a nice fillet joint and strong weld.
These cooling systems are fitted to classic cars like Jaguars and Triumphs which do not have the luxury of an electronic cooling fan. This new technology from Revotec, enables the engines of classic cars to survive our modern day conditions.

Laser welding and Electron Beam welding comparisons. Easy guide. The Disk or Fibre laser and the Electron Beam (EB) all make for good welding techniques and are both high power beam processes. They both produce neat repeatable welding procedures and due to the capital cost of the equipment are relatively expensive compared to conventional MIG […]

A client came to Carrs while trying to combat a medical condition called ‘Persistent Nystagmus’, an abnormal rhythmic oscillation of the eyes that is estimated to occur in 0.24% of the population. This effects a person’s ability to control eye movements, having a substantial impact on quality of life. CWT were able to  successfully weld […]
