Fiberfrax^® Anchor‑Loc^® 3 Insulating Fiber Module

The Fiberfrax^® Anchor-Loc^® 3 Insulating Fiber Module is designed to meet a wide range of application requirements in many types of heat processing vessels.

Unifrax specifications require inorganic spun fiber blankets for construction of the Anchor-Loc 3 module. The spinning process produces a long, tough fiber that contributes to the strength and stability of the needled blanket. Anchor-Loc 3 modules are manufactured from either ceramic fiber or soluble fiber chemistries to meet customers’ specifications or regional product requirements.

Advantages Over Refractory:

• Low heat loss
• Low heat storage
• Thermal shock resistance
• Fast thermal cycling (heat up/cool down)
• Energy savings (less fuel used)
• Easy to install
• Requires less maintenance

The two ceramic fiber blanket chemistries used for Anchor-Loc 3 construction are Durablanket^® HPS and Durablanket 2600 with temperature grades of 1316°C (2400°F) and 1427°C (2600°F) respectively. Anchor-Loc 3 modules are also constructed from biosoluble insulating blankets. For applications where operating temperatures may reach 1100°C (2012°F), the Anchor-Loc 3 module is fabricated from Insulfrax^® S blanket. For continuous operating temperatures up to 1260°C (2300°F), Isofrax^® 1260C soluble fiber blanket is selected for module construction.
