ZIRCAR Furnace Insulation Modules Type FIM are pre-assembled insulation systems constructed of premium grade ZIRCAR fibrous ceramic insulation layers encased in a rugged shell. Standard front and bottom loading models are available for use in air to 1700C (3100F) and 1800C (3272F).

These complete units  require only the addition of a protective furnace enclosure and power supply, with temperature controller, to build a complete rapid cycle furnace. Easy to use, they facilitate rapid furnace construction and use components that are easily replaced. 

A hot face of Alumina Insulation Type SALI-2 or SALI is installed in relatively small, fully supported, panels. This installation technique provides for long life during rapid cycling operation. An intermediate layer of Alumina Insulation Type ZAL-15AA is backed up with Alumina-Silica Insulation Type ASH. These 3 insulation layers are encased and supported by an outer shell of Refractory Hardboard Type FRA-600. A welded frame of high grade steel surrounds and protects the entire insulation package. Heating element holders, element straps & clamps, terminal boards, hearth systems and thermocouple holes are provided. Front loading models with center point hinged doors utilize Refractory Hardboard Type ARA-1000 door cowls secured with stainless steel fasteners which provide superior wear resistance.

Accessories such as heating elements,  thermocouples, hearth systems, and furnace module enclosures are available.

Many custom size & shape modules and those with unique features have been designed and fabricated including:
