This furnace is specifically for the controlled, slow cooling of glass products to relieve internal stresses introduced during forming (like blowing or casting). Operating at annealing temperatures (e.g., 550°C), it holds the glass at its annealing point before enacting a carefully programmed cool-down. The working principle uses precise temperature zoning and control to ensure all parts of the glass object cool at the same rate. Its purpose is critical for producing stable, strong glassware that won't crack from internal stress; it is used after any major glass-forming process.
Trutherm manufactures 700 Degree Celsius (700°C) Glass Annealer 520 × 875 × 520 MM Chamber for buyers who search by exact machine type, chamber size and 700°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 520 × 875 × 520 MM chamber with usable chamber volume of 236.6 litre, approximate power load of 26.400 kW, rectangular - tall chamber profile.
