One of India’s largest air cooler/heat exchanger manufacturers has ordered a vacuum furnace from Seco/Warwick. The customer’s choice is a three chamber CaseMaster Evolution (CMe)® furnace which will be used for heat exchangers. The client has decided on Seco/Warwick vacuum technology after a long period of trials with single and double chamber furnaces.

The CMe furnace with vacuum loading and cooling chambers is a semiautomatic brazing furnace that is quickly becoming popular especially in automotive, aerospace and defense industries due to its performance and high precision. Here, the client’s focus was on increasing production volume of its air cooling/heat exchangers. It is the first vacuum technology overall used by this manufacturer.

The client was previously using single-chamber furnaces but Seco/Warwick’s three-chamber technology became so attractive that the client conducted a number of trials at various heat solution providers to finally decide on the Seco/Warwick furnace. The engineering team played a great role in the process with professional support to train the client’s crew and acquaint them with the vacuum technology. As both parties stressed, there was a close cooperation on both sides and on all the levels starting with top management and finalising on operating levels of the production team. Sharing information was transparent and the learning process was smooth.

CaseMaster Evolution

CaseMaster Evolution–T (CMe-T) – a three-chamber vacuum furnace – delivers economical surface hardening using low-pressure carburising (LPC) technology and high-pressure nitrogen quenching. The CMe-T furnace can replace existing lines and generators used for mass heat-treatment under protective atmosphere and oil quenching, while ensuring higher precision and process repeatability. This solution stands out not simply because of its three-chamber design, but more significantly because of improved process quality, cost reduction from doubling yields, and increased production flexibility. Further, the CMe-T furnace’s intrinsically safe operation and low environmental impact are becoming more and more important to industry leaders as a whole. These are among the key reasons that aviation and automotive manufacturers are becoming increasingly attracted to CMe-T as their heat treat solution of choice.

“The client has chosen Seco/Warwick technology after long trials with other single and double chamber solutions from our competitors. Although initially the client focused simply on increasing the volume of production there was the whole spectrum of benefits not offered by the competitors. In a word, the advantage through technology prevailed” – said Maciej Korecki, VP Vacuum Business Segment at Seco/Warwick.

“Our engineering team worked closely with the client since this was the first vacuum technology purchased by the manufacturer; furthermore, Seco/Warwick is prepared to provide full customer assistance in implementing both technology and crew training at the site. We are very happy and proud to have successfully implemented another Seco/Warwick solution in India,” – added Manoranjan Parta, Managing Director Seco/Warwick India.
