Resistent

There are basically two types of heat exchanger available, which are selected depending on the application area:

Heat exchanger stainless steel V4A

Heat exchangers made entirely of V4A stainless steel are suitable for use in areas with aggressive air as well as for operation with heating media of aggressive composition.

Galvanized steel heat exchanger

This version is preferred when the room air is heavily contaminated and the heat exchanger needs to be cleaned regularly. The robust design allows mechanical cleaning.

Compared to the copper/aluminum version, the thermal output is reduced, but it offers greater resistance to external influences.

The units are available in several model sizes to allow the output to be tailored to requirements.

The model size is selected depending on the required thermal output, the air volume flow and the sound requirements of the room.

Larger model sizes offer higher performance, but are associated with larger housing dimensions, which must be taken into account when planning the installation situation.

Depending on the application area and application, variants with different heat exchanger areas and numbers of pipe rows are available. Units with a reduced heat exchanger surface area enable particularly high air volume flows and a deep air supply into large rooms. For demanding heating tasks, especially in the (operated) at low temperature range, we recommend versions with an increased heat exchanger capacity and several rows of pipes. These achieve a high heat output even at low flow temperatures and are ideal for modern, energy-efficient heating systems.

• The Resistent is designed for use in extreme conditions.
• Where aggressive air needs to be ventilated, the Resistent shows its strengths.
• Both the housing and the heat exchanger are made entirely of stainless steel.

• The unit heater can be mounted on the ceiling or wall.
• Ceiling-mounted is preferable to wall-mounted.
• Warm air pockets under the ceiling are reduced and an even flow is ensured.
• If the structural conditions do not allow the unit heater to be mounted on the ceiling, wall-mounted installation is possible.
• To be mounted from 2.5 m height lower edge.
• The throw is highly dependent on the hall layout and the room geometry.

• Determination of the heat load according to DIN EN 12831

Determination of the unit or unit size with the design criteria taking into account:

• Heat load and heat output
• Acoustics
• System temperatures

• The unit heaters should be arranged symmetrically in the room to ensure an even flow through the room.
• Structural conditions such as lintels, ceiling cranes or other installations must be taken into account.

• For comfortable conditions in the occupied zone, the temperature-controlled air must be introduced precisely.
• All blow-out characteristics can be achieved using a wide range of diffusers.
• The diffusers are made of stainless steel for heavy-duty use.

• Any type of mounting can be realized using brackets available as accessories.
• Whether wall brackets or ceiling brackets - maximum flexibility can be achieved for any structural conditions
• The brackets for the Resistent are also made of stainless steel.
