Chemical processes processes<div class="ExternalClass6C7F86C99BC44C2E9CA2FE192F3E2F10"><p>The chemical sector is such a diverse industry that the range of applications for our products is very wide. Our experience across a wide variety of gas mixtures, including extremely corrosive compositions, enables us to select the construction materials that will provide the most durable and safe long-term service for each individual application.</p><p>Fans can be supplied to be gas tight and made of special materials to resist corrosion. Diaphragm compressors maintain the highest cleanliness of gas being compressed, preventing gas contamination by means of complete separation from mechanical lubrication and the external atmosphere.  Diaphragm compressors are frequently used in chemical processes (Fluor, Polysilicone) and have a high pressure capability for reactor feeding while piston compressors are custom designed with regards to materials and instrumentation for handling complex chemical gases. </p><p>Blowers and turbo-compressors are supplied to provide air for carbon black plants and for sulphuric acid plants. <br>Howden screw compressors are used for gas handling and in refrigeration plants while Howden ExVel(R) turbo fans are used in MVC evaporators to concentrate chemical solutions for transport and further processing in crystallizers or dryers.<br></p></div><div class="ExternalClassABCB9436FB7F43F8A0E3C5CD49A3DE8F"><p>Equipment that keeps the product purity and that can handle toxic, corrosive and unstable gases</p></div><div class="ExternalClassDCC032676120421198AEE4F0CC38EA06"><div class="container-fluid benefits-panel bg-Hgray" style="padding-top:0px;padding-bottom:0px;"><div class="container"><div class="row"><div class="col-md-4"> <img class="icon" src="/assets/portal/Process/icons/icon-custom-services.svg" alt="" /> <h3 class="white">Comprehensive, Customized Services</h3><p class="white small-text">We supply a range of equipment to the chemical industry, from fans for process heating and cooling, to compressors that are used for gas compression and processing.</p></div><div class="col-md-4"> <img class="icon" src="/assets/portal/Process/icons/icon-bespoke-packages.svg" alt="" /> <h3 class="white">Bespoke Packages</h3><p class="white small-text">The important differences in gas composition to process constraints make our ability to custom-design for specific needs and site conditions enormously valuable.
