DBM Technologie

DBM Technologie is a manufacturer and supplier of high-temperature insulation heat shielding for protection up to 1,400°C, and is available in flexible or rigid form.

High-temperature thermal insulation

DBM Technologie works at several levels:

• Research and development
• Prototype and productionisation
• Serial production
• Qualification and certification

The main products manufactured by DBM Technologie are rigid heat shields, flexible insulation blankets to protect valves and piping, fire screens, and insulating / heating shells.

The company offers innovative solutions to a variety of markets, including power generation, aeronautics, railway, automotive and industrial applications.

Rigid and detachable flexible insulation on an exhaust pipe.

Thermal screen insulation of an exhaust manifold.

Thermal screen insulation of thrust reverser for aircraft engine.

Detachable blanket with hook fastening.

Large fire-screen without thermal link for train.

We are ready to respond to our customers’ requirements and work with them on their projects.

Integrated heat shields

DBM Technologie designs and manufactures high performance integrated insulation heat shields to give thermal protection for temperatures of up to 1,200°C.

The insulation is applied in two ways:

• Integrated: it is fixed by us on to the items to be insulated
• Half-integrated: the customer attaches the insulation to his equipment

The insulating materials composed of glass fibre or silica powder agglomerated by a binder are generally encapsulated in thin refractory stainless steel, inconel or titanium sheets depending on the requirements. The insulation could be in glass fibre (500°C), silica fibre (1,000°C) or silica powder clustered by binder (high-performance insulation with low thickness).

The advantages are:

• Mechanical durability
• Excellent vibration strength
• Excellent resistance to fluid contamination
• Reliability, limited thermal bridge

Typical applications:

• Engine exhaust manifolds and turbochargers
• Exhaust system piping and components
• High-temperature ducting

Detachable heat shields

DBM Technologie designs and manufactures high-performance detachable insulation heat shields that provide thermal protection for temperatures up to 1,200°C. Typically, this form of insulation is detachable and composed of two half shells, which are hinged together.

Insulating materials consist of glass fibre or silica powder agglomerated by a binder, they are encapsulated in thin refractory stainless steel, inconel or titanium sheets, depending on the requirements.

The insulation could be in glass fibre (500°C), silica fibre (1,000°C) or silica powder clustered by binder (high-performance insulation with low thickness). Usually the encapsulation is done with refractory stainless sheet of 0.1mm or 0.15mm in thickness, but when we need a significant mechanical strength, the heat shield encapsulation stainless steel could have a thickness of more than 1mm.

The advantages are:

• Simple logistics; the customer’s component is not sent to DBM
• Mechanical durability and excellent vibration strength
• Excellent resistance to fluid contamination
• Reliability

Typical applications:

• Engine exhaust manifolds, exhaust system components and turbochargers
• Piping and ducting
• High-temperature exhaust of gas turbines
• Industrial and power generation systems heat shielding

Flexible insulation blankets

DBM Technologie designs and manufactures high-performance soft thermal and acoustic protection. This type of insulation can protect against temperatures of up to 1,400°C.

Insulation is applied in two ways; it is either detachable or integrated onto the items needingto be insulated. A mock-up is frequently used to quickly create a prototype of the thermal insulation. The series of insulators can be assembled with hooks or industrial self-gripping (Velcro).

Thermal insulation

Our thermal insulators are made of fiberglass (up to continuous temperature of 500°C), silica fiber (1,000°C), silica aerogels (650°C). They are encapsulated in special fabrics resistant to heat, made from glass, silica or aramid fibres. Depending on the application, these fabrics are coated with silicone or Viton®. The coating laid on the outer fabric allows a fluid seal in the case of projections; it also satisfies environmental standards such as resistance to salt spray, humidity and fungus. The insulation can have a minimum thickness of 3mm.

The outside of Silcamide complex is composed of insulating glass fabric coated with silicone and the inside of thermally desized glass fabric, while insulation is a needled fiberglass. The Noviamide complex is composed of Nomex® fabric coated Viton®.

Acoustic insulation

Acoustic fibres are encapsulated in aramid fabric with customised weaving.

Typical applications:

• Pipe insulation
• Valve insulation
• Insulating conduit
• Thermal cover
• Acoustic insulation and sound attenuation

Design and manufacture of fire-screens

DBM Technologie designs and manufactures fire-screens in soft or rigid insulating material. The insulators customised for the application are held in envelopes made from thin refractory stainless sheets and fireproof fabric.

These products enable protection from fire for durations specified by the customer. Fire protection material can be manufactured in small or bigger sizes and up to several metres of length or width without thermal link.

Typical applications:

• Fire-screen protection for collective passenger transport
• Fire protection for military vehicles
• Fire protection for industrial applications, such as furnaces and engine bays
