SUM Exhaust Guard

SUM Exhaust Guard covers offer excellent resistance to high temperatures ranging from 450°C to 1000°C, thanks to the availability of a wide range of reinforced fabrics and insulation materials, including glass fibre (HT, HTM), silica and ceramic insulation.

SUM Exhaust Guard covers are designed as thermal insulation jackets for a wide range of engine exhaust system components, including:

• Exhaust manifolds and exhaust pipes
• Silencers, diesel particulate filters (DPF) and catalytic converters
• Turbochargers (turbine/exhaust side)
• Flexible connectors and expansion joints
• Industrial generator sets
• Rail vehicles
• Heavy mining and construction equipment
• Military vehicles
• Agricultural machinery
• Marine propulsion systems

The SUM Exhaust Guard range is also frequently adapted for other high-temperature applications, including:

• Hot components within industrial process installations
• Extruders, injection moulding machine heaters and turbines

The primary functions of SUM Exhaust Guard covers are:

• Protecting the surrounding environment from unwanted radiant heat
• Improving the efficiency and performance of filters and catalytic converters by maintaining their optimum operating temperature
• Extending component service life through the stabilisation of operating temperatures

The covers are designed for repeated use and can be removed and reinstalled without damage.

Inner and outer technical fabric layers – High temperature resistance ranging from 450°C to 1000°C, achieved through the use of a wide selection of reinforced glass fibre fabrics with G2, TG and HT finishes, as well as silica and ceramic fabrics.

Insulation core – Approximately 80% of our products utilise mechanically needled E-Glass insulation felt. Unlike conventional mineral wool insulation, it offers:

• High density: from 130 to 180 kg/m³
• Excellent water resistance – even after complete saturation, it regains 100% of its insulating properties once dried
• Outstanding durability and mechanical integrity – resistant to deformation caused by bending, with no delamination or fibre breakdown

For higher temperature applications, silica mats, Pyrogel®, ceramic paper and other advanced insulation materials are used.

Fastening and edge finishing systems are always tailored to the specific application, taking into account operating temperatures, surrounding equipment and the user’s individual requirements. Available fastening solutions include industrial hook-and-loop fasteners (including high-temperature grades), stainless steel buckle straps (standard), stainless steel hooks and other specialised fixing systems.

Identification plate – Each cover is assigned a unique serial number, and its design specification is stored indefinitely in the SUM database. The identification plate may also include any information required by the customer, such as installation location, valve numbering or asset identification details.

All fittings and fastening hardware used in every version of a SUM cover are manufactured from stainless steel.

Exceptionally strong seams, sewn with stainless steel thread braided with Kevlar®, ensure long service life and excellent resistance to high temperatures.
