CSN® Braking Resistors are used for controlled braking of every kind of electrical drives. Braking resistors convert the energy of drives into thermal energy which will be dissipated into the corresponding cooling medium. Design variations with natural or forced air cooling are available. CSN® Braking Resistors can be delivered with an indirect water cooling system using an airwater heat exchanger as well. The design of the CSN® Braking Resistors is particularly suitable for use in maritime applications. Schniewindt, as global market leader in this resistor sector, has a wealth of experience in the design according to the technical guidelines and rules of international classification societies for example

Explosionproof/flameproof gas preheater EEx d -ATEX und IECEx zertifiziert In general a cooling down takes place at expansion of gases whilst a heating takes place at compression. Typical gases are carbon monoxide, natural gas and air. The temperature change, which occurs at expansion of gas or gas mixture from a high to low pressure i.e. after a gas pressure control is called Joule-Thomson effect. In order to prevent the effects of Joule-Thomson as icing or condensate separation, the gas will be heated up before expansion. The gas pre heaters are suitable for all kind of gaseous media (i.e. air, natural gas, technical gases, fuel gas) and low flow process applications, suitable for pressures up to 300 bar. The “Cast electric heaters” type flameproof electrical gas pre heaters are certified for use in zone 1 or 2 hazardous area, custom built to meet client specification. The gas pre heater consists of a process tube coil and an electrical heating bundle, casted in aluminium. The process gas flows through the tube coil and is heated by the aluminium block that provides the heat transfer. This indirect electric heating gives an accurate control of the process and eliminates pressure vessel design and associated costs.

A closed end rivet The rivet body of the GESIPA CAP ® blind rivet is absolutely air and watertight. Liquids cannot seep through, could however seep around the set rivet, if the setting hole is too large. Therefore great care must be brought to fullfi lling the hole tolerances. The GESIPA CAP ® blind rivet – The structure For technical reasons, the rivet mandrel of the GESIPA CAP ® blind rivet must be fi xed in the rivet body. However this means that the rivet body can only deform slightly during the setting process. As a result, the cap blind rivet only has marginal hole fi lling capability. However this is necessary to be able to compensate large bore-hole tolerances. The GESIPA CAP ® blind rivet – Tight connections with care The above-mentioned technical situations make careful preparation of the application imperative. The hole diameter should be as tight as possible to ensure a fl awless function in the application for a long period.

Bio scrubbers are systems for the biological cleaning of exhaust air and exhaust gases and thus for the reduction of odours and polluting emissions. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The bio scrubbers from WesselUmwelttechnik work almost without wastewater and are therefore very sustainable, regardless of the nature of the exhaust air. The basic requirement, however, is that the ingredients are watersoluble and bioavailable. WesselUmwelttechnik supplies turnkey plants like the Wessel BIOCATScrubbers in single and multistage construction.

Due to its process-integrated biological degradation, the biofilter is an incomparably cheap and efficient procedure for odour removal and the treatment of low concentrated or undefined air flows. This advantage lies in the natural decomposition of air pollutants into harmless products. Incomparaply cheap technique Simple process technology Operation through permanent staff of the operator Advantage through the natural reaction conditions of the catabolism Flexible concept Reduced operating costs regarding Energy consumption Water consumption and effluent water Use of chemicals Maintenance efforts Long-lasting construction Plant components of corrosion resistent and chemical resistant materials Biologically active filter material High inner surface for the settlement of microorganisms Steady perfusion Good drainage impact Integrated pre-scrubber Dampening of the air until saturation Stripping of pollutants through the microflora for an optimal operation Dosing of various...
