Disc Heaters
Disc heaters, sometimes called as Ring Heaters, are used for heat transfer by conduction or convection to heat liquids, air, gases and surfaces.
Materials
These unique heaters are constructed or a rust-resisting iron sheath (750°F Max Temp.) with optional chrome steel sheaths (1200° F. Max Temp.) available. They are precision pieces of equipment proven to be suitable for continuous duty applications. Heater reliability is assured by high quality nickel-chromium resistance wire, which is embedded in a special ceramic formula developed for long life with excellent heat conductivity. This refractory insulation is compressed and the cured in high temperature ovens to insure maximum quality.
Typical Applications
The primary application of ring & disc heaters is the heating of flat surfaces: tank bottoms, melting pots, hot plates, platens, dies, molds, coffee urns, vacuum pumps (diffusion pumps), incubators, vulcanizers, ovens and resistive load banks.
Installation
Ring & Disc heaters should be clamped firmly to the application surface. Small diameter disc heaters can be nested inside larger ring heaters to increase heating capacity. Center holes of all heaters accommodate positioning of the heater & facilitate mounting to threaded studs welded to the surface to be heated. Utility clamps are positioned over the heater and bolted down upon the threaded studs. The studs can also be through bolted vs. welded. Tighten clamps wrench tight and the back off 1/2 turn for expansion.
