Energy-optimized specialists for heating, painting and drying processes
Our combustion chambers offer high levels of efficiency for a wide range of heating, painting and drying applications. In their industrial applications, heat exchangers are mainly used to realize the transfer of thermal energy between different material flows. In order to achieve this with the lowest possible primary energy input and thus in a cost-optimized manner, LK Metallwaren offers special heat exchangers with high efficiencies for a variety of heating, painting and drying applications in three material combinations.
In the standard version, heavily stressed parts (such as combustion chamber drums) are made of heat-resistant alloyed steel. In two special designs we offer combustion chambers made of heat-resistant alloy steel or heat- and corrosion-resistant Cr-Ni steel.
Combustion chamber LKVDE
Special heat exchangers type LKVDE are designed (horizontally or vertically positioned) for installation in already existing housings. In the standard version, they allow heating by 60 Kelvin at a maximum discharge temperature of +300 degrees Celsius. If required, we can also provide our customers with combustion chambers with higher heat output, higher heat-ups and additionally with customized exhaust gas ducts.

Combustion chamber LKT
Special heat exchangers type LKT are designed for process heat with Discharge temperatures of max. +100 degrees Celsius designed and are particularly suitable for use in ventilation systems and for painting and drying processes. They can be installed both horizontally and vertically in an insulated housing. LKT heat exchangers are used as standard in our LKPT compact units (supply/return/recirculation units). They are also available to our customers as spare parts for defective equipment as well as for hot air furnaces. Assuming a heating of the air flow of ∆T= 35 Kelvin and discharge temperatures of max. +100 degrees Celsius are available in the following sizes and nominal heat outputs. If your requirements go beyond that – we will find a solution for you too!

Combustion chamber LKNTS
The special heat exchanger LKNTS is designed for process heat with low discharge temperatures and condensing operation. Because of condensation, only heat- and corrosion-resistant Cr-Ni steels are used in the construction of the combustion chambers; in addition, they are surface-treated by spraying or dipping. Each special heat exchanger is designed specifically for the customer in accordance with the process engineering specifications. Depending on the application, the efficiency of the combustion chamber can reach up to 92 percent. The LKNTS is available in the following sizes:

Accessories
Insulated front panels
Insulated faceplates are provided for special heat exchangers for installation in existing housings and ducts. Insulation thickness is available as standard in the following sizes: 100, 150 and 200 mm; others are available on request.
Sliding flange
The sliding flange is designed for combustion chambers for safe penetration of existing insulated walls. The standard sliding flange is offered in insulation thicknesses of 100, 150 and 200 mm; thicknesses deviating from these can be realized at any time on request.
Reference project combustion chamber for drying processes
In April 2023, we received an order from a renowned special plant manufacturer from Münsterland to supply 16 heat exchangers for use in drying processes. You can find out more about the challenges and progress of the project on the following page:
