IEL was founded in 1930 by John Brook & Sons outside London. In 1939 a
new branch was opened in London, and in the same year the company completed
the first foreign order. In 1940 the enterprise was closed down and all the
equipment and machinery were shipped to the East. In post-war years (1950-1952)
the company reopened some branches and streamlined the enterprise to satisfy the
needs of the country. In 1992 it became a self-managing establishment. Its foreign
business started flourishing again.
The company produces process equipment. It consists of six departments:
Production, Sales, Export, Financial, Personnel and Research & Development. The
last one is the newest at the company, they created it five years ago. The
management is the Board of Directors. Currently they employ about 1600 people.
Their feernover is more than E300 million.
Recently the company has concentrated on the timber business, which has
enabled the enterprise to develop furniture production. This will lead to increase in
profits and earnings.
The company sells its products to five countries in Easten Europe. The
management hopes to penetrate some international markets in the near future. This
has become the driving force of the enterprise. The company would like to expand
its activity towards the West. To do that its representatives establish personal
contacts with different companies of the world.
They study through by their business offers, price-lists, catalogues. They
make Draft Contracts, but first the representatives discussed them with Directors,
sometimes by phone. Before signing a contract, the representatives negotiate terms
of payment, shipment and delivery, discounts, packing, transportation. ​
