The Sentratek IMPEX Division was formed to support our Client’s need to move chemical products and equipment around Sub Saharan Africa in a timely and economical manner. The products and systems that are moved for Sentratek by this division are aimed primarily at cost optimization for the end client and as importantly the improvement in safety during the shipment and handling of hazardous chemicals. IMPEX 's main functions are the sourcing, importing and exporting of chemical products and various equipment components on behalf of the Sentratek divisions and their clients in Africa.

Through close co-operation with their freight forwarding and logistics partners, we take care of the complex chemical product export and logistics procedures from South Africa into countries in Sub Saharan Africa. IMPEX provides a vital logistics service to Sentratek clients across Africa who are wanting to source spares and equipment that are not readily available in the countries in which they are operating. IMPEX will source the items (or fabrication thereof) and calculate the quickest and most economical route to the customer directly from the supplier or manufacturer. Our knowledge and understanding of the import and export requirements for each country allows us to provide an efficient and economical service to Sentratek and its Africa-based clients. 


The development of the Shield Range of technologies was undertaken by a team of technology specialists who are available to offer advice, conclude designs or forward Standard procedures for various process cleaning requirements in various industries.

Our support team consists of specialists in various industries which offers our clients confident and cost effective options when choosing their chemical products and equipment supplier.
