Company

We are an engineering company with a large experience in industrial installations for the reception, storage, transport as well as the ingredient dosing into manufacturing processes. Moreover, we are specialists in developing technology, producing machinery and creating installations for a wide range of sectors such as the feed and food, cosmetic, chemical, and pulp and paper industries.

Over the last 30 years we have been developing a great number of successful installations and controls to help our customers in their needs of dosing great quantity of ingredients.

At MANGRA we design, manufacture and set up storage and reception tanks, chemical preparation equipment, ingredient dosing equipment, filtration systems, process control systems, heat exchangers (steam and electrical) and the complete piping and all the components needed to perform a turnkey installation.

Thanks to our highly qualified team which is permanently innovating and doing research we own a leadership position in the ingredient dosing and control market.

What is more, because of our state of the art dense phase pneumatic transport technology, which transports either granular or powder material,we are proud to claim that our customers are provided with the most competitive advantages for their businesses.

Not only this innovative technology allows energy cost savings, but it also has a flexible application and no maintenance at all and it replaces conveying belts, bucket elevators, screw conveyors and dilute phase pneumatic transport.

Finally, our system optimizes significantly the conveyance process and minimizes the installation and start up costs.

Our customers will be assisted by specialized engineers in the design of the installation, technical support and mechanical assembling. Furthermore under customer request we can supply with turnkey basis. Equipment available in AISI 304 or AISI 316 stainless steel, for temperatures up to 200°C and ATEX 21 and ATEX 22 configurations.

Our technical office is at your disposal to develop any needed customized request to help you grow your business.
