Deltech manufactures standard and custom electric resistance lab scale and production furnaces and control systems for operating temperatures from 1400 deg C to 2000 deg C in air, inert atmospheres (with and without vacuum assisted evacuation), and under positive pressures. We offer a special “RS” line for glass melting applications. We also maintain stock and supply related spare parts including reline kits, heating elements, thermocouples, and ceramics including hearth plates. We sell, install, and service our products domestically and internationally.

Now celebrating completion of our 51st year, Deltech has established a reputation for taking on the custom projects that others will not, and without the customary charges for the engineering time required for custom designs.
