Largest stock holder of vacuum & atmosphere sealed quench furnace spare parts

Vacuum & Atmosphere Services Ltd are the UK’s largest stock holder of vacuum & atmosphere sealed quench furnace spare parts, holding in excess of 80,000 spare parts.

VAS stock & specialise in Ipsen sealed quench atmosphere furnaces & hold in stock hearths & muffles from Ipsen TQ4 up to TQ17.

The silicon carbide and Mullite (MulSiC) mixture, specially designed by VAS furnace engineers & experts, has a significant advantage against pure forms of Silicone Carbide or Mullite muffle furnace parts.

The massive advantage for VAS hearths & muffles is the excellent resistance against “glazing” the hardening of the surface by means of glass type residues. The VAS hearths & muffles also have a high resistance to thermal shock & long working life.

Pure Silicon Carbide has a long working life and a high resistance to thermal shock. However, it is very susceptible to the “glazing effect” causing irregular granular growth, reduced passage and consequently early failure. Pure Mullite is almost totally resistant to glazing, however, it only has a very short life, particularly with exposure to frequent temperature changes.

For all of your hearth & muffle enquiries please do not hesitate to get in touch with us at enquiries@vacat.co.uk or call us on +44 (0) 121 544 4385
