TDL8411

Thermal Dilatometer

Detects thermal expansion and contraction changes within samples with high reproducibility.

Utilizing a differential expansion method that cancels thermal expansion and contraction caused by the detection mechanism, this instrument enables precise and reproducible measurements, even for low-expansion materials or thin samples. An optional auto-sample changer can also be installed, contributing to energy savings and high throughput. Additional features include a built-in air-cooling fan to shorten cooling time after measurement completion and an automatic sample length measurement function.

Dramituff Standard version

DRAMITUFF is a single component, air setting, castable. It has a very good abrasion resistance, cold crushing strength and chemical resistance. It can be hand packed or rammed in thin lining applications. DRAMITUFF is based on a proven binder system, which allows a wide range of water addition, giving working

Anchors for Fibers – Series D

Anchors produces refractory anchors for fibers (for insulating blankets, insulating boards/pannels, modules fibers). The fiber linings are common when we need the lining with good thermal shock resistance and a fast installation. Example : heat treatment furnaces. D1 : “Cerafix” type anchors «CERAFIX» type anchors : Anchors for fibers with

Support Brackets – Series C

Anchors produces refractory support brackets. Support brackets are used when the walls of the furnace are high.This enables to spread the weight on the refractory which reduces the risk of deterioration of the wall. They are also often placed around doors or < openings > to reinforce the refractory on

Brick Anchors – Series B

Anchors produces refractory anchors for bricks linings. B1 : “BSTP” type anchors BSTP1/BSTP2 : Brick anchors for linings composed of refractory insulating bricks, this type of lining is common in petrochemistry for example. Download “BSTP” B2 : “BR” type anchors Anchors for lining on dense

Castable Anchors manufacturer – Series A

Anchors produces refractory anchors for castable linings. Our range can suit all applications, We produce refractory anchoring systems in round and flat material, for hand welding, for gun welding, for all types of concrete density. A1 : “CH” type anchors CH1 – CH2 – CH4 – CH1RL : Castable anchor
