Schniewindt GmbH & Co. KG

CSN® air heaters are characterized by a wide range of uses and applications. In addition to the use in industrial drying and in process technology, they can be mainly used in workshops, air conditioners, construction sites, cranes and lounges. They are used for direct heating of flowing air or non-flammable gases and mixtures.

CSN® air heaters are available in different variants. Besides the use of CSN® tubular heating elements, we also obstruct CSN® heating grid.

Thus, the different strengths may be optimally aligned to your needs.

Optionally, et al Temperature monitors and limiters, thermocouples, custom electrical controls and built-in fans possible.

CSN® explosion-proof heaters are used for heating up gases and liquids in hazardous areas.  

Our products realize individual solutions for complicated technical process. Different heating systems for heating up liquids, nitrogen or other gases activate exact determinded processes in chemical factories. In close discussion with our customers problems will be defined and changed in technical optimale solutions. Our Quality-Management-System ensures the high quality level of our customers.

CSN® FLOW HEATERS FOR THERMAL PROCESS APPLICATIONS

Typical Fields of Application are in the chemical, petrochemical, railroad and shipbuilding industries, in the machine and industrial equipment construction. CSN® circulation heaters are manufactured in close coordination with our customers from a few watts to the megawatt range, a division in individual circuits is made according to customer’s requirements. Equipment for installation in hazardous areas we produce in protection class „Ex d“, „Ex de“, „Ex e“.

On request, CSN® circulation heaters are supplied with optimized process controls. Please contact us to talk about the most appropriate control system. Schniewindt is certified by the Lloyd’s Register to produce equipment according to the Pressure Vessel Directive 97/23/EG and a certificate from TÜV (Technical Monitoring Agency) certifies that we meet the prerequisites for welding procedures according to AD 2000 Merkblatt HP 0 / DIN EN 729-3.

Product advantages:

A wide range of possible applications in the electric heating of liquids and gases, high quality electric CSN® tubular heating elements produced by Schniewindt and a surface load perfectly adapted to the process condition in combination with the use of high quality stainless steels ensure a long service life, high efficiency by direct heating of the fluid, easy operation and low maintenance costs.

Equipment design:

Highly compacted U-shaped CSN® tubular heating elements are welded or hard soldered into blind flanges with diameters up to DN 1000 (40”) and inserted and mechanically fixed to cylindrical (tubular) pressure vessel. According to customer’s specification, the vessel will have nozzles prepared for welding, threaded pipe couplings or welding neck flanges. The terminal housings comply with protection class IP-65. The production of the CSN® circulation heaters is according to the guidelines of Directive 97/23/EC (Pressure Equipment Directive), the tubular heating elements in diameters of 8,5 mm, 11,5 mm and 16 mm are available, on request, sealed according to the Giso process, guaranteeing a high insulation resistance. Various stainless steel materials for different fluids are available. Depending on customer’s requirements, our heaters are designed with kilowatt ratings up to the megawatt range. For a precise temperature control, mechanical thermostats or temperature limiters, Pt-100 RTD’s or thermocouples are available.

CSN® screw-in heating units are particularly suitable for the direct heating of liquids, air and gases.

In relation to the process, we provide you with screw-in or tank heating units with tubular heating elements made of stainless steel which we adjust to the respective application situation and the medium to be heated in consultation with you.

The surface loadings, a very critical design feature for the long-term durability of the elements, are calculated for their specific application.

For exact temperature monitoring, the screw-in heating units can be manufactured with various controllers and / or limiters, as well as PT100 sensors or sheath thermocouples.

Our team also looks forward to standing by your side if you need heating solutions which cannot be covered with so-called standard solutions. We are happy to develop process-customised solutions in close consultation with you. We look forward to your task. Various fitting sizes, voltages, installation lengths up to 3.5 m and a wide range of materials make this device a universal solution.

Nowadays, amongst others, our high quality standards are documented via the „Giso-Verschlusstechnik“ (Giso locking technology), with which we specify the isulation resistance values of our heating elements clearly above the values recommended in DIN 44874.

Thanks to worldwide co-operations, we now belong to the leading suppliers of electronic heating technology and are therefore able to provide our customers with various international licenses and certifications (e.g. Gost, UL/CSA, DNV, etc.) for various product groups.
