Wall bushings, ceiling and roof ducts are used wherever the exhaust pipe is routed through components made of combustible materials.

Wooden houses are enjoying increasing popularity. However, additional attention must be paid to fire protection when building them. Special protective measures are to be taken above all if a heating system or a stove is to be installed. This applies primarily if the heat generator is connected to the chimney through the wall. In this case, Schräder’s wall bushing, ceiling and roof ducts provide maximum safety.

The product is available in three insulation thicknesses, numerous diameters and various lengths. It can also be used with composite thermal insulation systems - and it is approved by the German Institute for Building Technology in Berlin under number Z-7.4-3408 and thus offers tested safety.

Lightweight shaft system for all standard fireplaces for refurbishment and new construction

This system consists of a shaft made of 45 mm thick THERMAX SL® thermal insulation panels in combination with the proven Schräder exhaust gas systems "Sanro - Aqua", "Future E" or "Future C" in the pipe diameters DN 80 to 600 mm, which are suitable for connection to all standard fireplaces in positive and negative pressure. It is not necessary to additionally insulate the pipe system with insulating sleeves (exception: LAS operation for solid fuels).

Thanks to the lightweight construction of the shaft, which is equipped with a spring system on one side, the installation can be carried out without any problems. The pipe elements and fittings are made of stainless steel (1.4404) as standard and are designed as usual with an expansion or bead side. The capillary effect within the tube column is prevented by the introduction of beads.

The Schräder System Future - Therm has the fire resistance class LA 90 and therefore does not have to be covered additionally.

With the lightweight chimney Future-Therm 45, Schräder is presenting the first certified lightweight chimney at ISH. The renowned Passive House Institute in Darmstadt has issued the certificate for the chimney as a passive house component and will present it at the ISH. The certification fulfils additional requirements in the thermal and building physics fields.

The advantages at a glance:

• Suitable for all standard fireplaces
• Fire resistance class LA 90
• Easy assembly due to low weight
• Space-saving design
• Short assembly times due to modular construction system
• No additional installation of insulating sleeves required (exception LAS for solid fuels)

The granting of the approval for the mounting shaft allows maximum application possibilities.

Increase energy efficiency - reduce costs  

Enormous amounts of heat are generated in domestic or commercial boilers, combustion plants and industrial processes. The waste heat is released into the atmosphere via the chimney.

Part of the generated energy remains unused and is lost!

Heat exchangers make it possible to transfer heat from a warm medium to a colder medium. In the Turbu-FlexS AWT, the exhaust gas is led past a coil and heats the water conducted into the coil windings. The bimetallic baffle plates inside the coil cavity deflect the hot exhaust gases several times. The heated water raises the boiler return temperature or can supply individual consumers directly with hot water.

Schräder supplies the technology that not only reduces your costs, but also contributes to the reduction of emissions and thus to active environmental protection.

The three product variants TurbuFlexS-300, TurbuFlexS-600 and TurbuFlexS-900 are available. All have a DN200 stainless steel exhaust pipe with a material thickness of 1.5 mm. The inlet pipe is wide in the standard version and the outlet pipe is narrow so that the exhaust heat exchanger can be installed like a standard exhaust pipe. Several heat exchangers can also be combined in a series or parallel connection. The designs can be flexibly adapted to customer-specific requirements.

Your benefit:

• Reduce costs
• Use energy reserves
• Protecting the environment

TurbuFlex advantages:  

• Hot water in a short time
• Universally applicable
• For solid, liquid and gaseous fuels
• Little space required
• Vertical, horizontal or oblique mounting
• Low installation effort

Examples of heat sources:

Heating boilers with fuels: wood chips, logs, pellets, oil, gas, coal

Firing systems: wood-burning stoves, heating inserts, tiled stoves, hot-air stoves, baking ovens, pizza ovens, drying systems, roasting systems, kitchen blocks, process heat generation systems  

ELECTROSTATIC FINE DUST SEPARATOR FOR HIGH-PERFORMANCE WOOD COMBUSTION PLANTS

In the Filterbox-S, the exhaust gases from the boiler are first directed and led downwards from the inlet nozzle. They flow through stainless steel pipes in which both electrostatic charging and particle separation take place. The purified exhaust gases then enter the chimney. Depending on the fuel and the condition and operation of the furnace, the separation efficiency is between 80 and 90 percent. The electrodes and separating surfaces are cleaned automatically by means of a vibrating mechanism (dry cleaning). The dust falls into a collecting container during the cleaning process.

The advantages at a glance

The modular 100 kW units can be compactly assembled at the point of use ("standard door suitability")

The powerful wire electrode ensures high separation efficiency with low power consumption

Fail-safe and stable operation due to minimal mechanics

Automatic dry cleaning by vibration ensures simultaneous dedusting of electrode, separator tubes and housing.

Easy maintenance due to several cleaning and inspection openings

Low operating costs

Integrated bypass and shut-off prevent reentrainment during the cleaning process

Increasing energy efficiency - with Schräder exhaust gas heat exchangers

INDIVIDUAL SOLUTIONS

Schräder does not offer standardized heat exchangers. All systems are individually planned and manufactured according to the requirements and needs of the respective project. This guarantees the highest power yield with optimum adaptation to the location

Laser-welded finned tubes inside the Schräder heat exchanger offer a large surface area and thus ensure particularly high heat transfer. Compared to heat exchangers with smooth tubes, the Schräder heat exchangers are much more compact.

The Schräder heat exchangers are made of high-quality stainless steel (1.4404/1.4571). Special designs are also possible for special process-specific requirements.
