‘Armoured’ heat exchangers from IT Tech Swiss TRADITIONAL SiC heat exchangers offer the advantage of the high heat exchange coefficient typical of silicon carbide. The weak point of the system is the sealing between the separation plates and the tubes. At 100°C, PTFE loses tensive stress, hindering the proper sealing between plates and tubes. Leaks from traditional heat exchangers are due to fluid leakage near the plates. chemical aggression enhances reliability and life cycle duration. Guardian heat exchangers are provided with a sealing system realised through Guaflon™ (modified filler PTFE) threaded bushings, which couple to the threading of the PTFE plate, blocking the tubes. The seal is provided by elastomeric O-rings that allow the tubes to expand without compromising the seal tightness. The O-rings are made of Kaflon™ 79P, for the highest degree of elasticity, softness and thermal resistance. IT Tech Swiss SA – Switzerland Email: info@ptfe.ch Website: www.ptfe.ch

The IT Tech Swiss research and development department has worked during the last three years to optimise a new technology for the manufacturing of heat exchangers: the Guardian™ armoured PTFE exchanger. The special ‘armoured’ plates are made from stainless steel with an outer PTFE lining of suitable thickness. While the stainless steel armour guarantees rigidity of the separation plates, the PTFE lining ensures chemical inertia. Splitting the tasks of providing structural rigidity and resistance to
