The complete programme of DEC International was developed in such a way that it can be used under all circumstances. This is why DEC International can operate all over the world. Our technicians can turn their hands to most things. The flexibility of the product range and the flexible attitude of the staff ensure a good product.

Below you will find an overview of some of our projects in various countries.

Emirates Stadium

E and S installation has fitted the ventilation system. The company has a clear preference for DEC International flexible air duct systems firstly, because the SONODEC series has exceptional sount attenuation properties and secondly because the flexible ducts are such high quality.

Russia Offices BCG Moscow

Boston Consulting Group works throughout the world on different specialities for every large industry as does DEC International. Both enterprises come to pioneering ideas through their decisiveness and cooperation. This project, which has been realized with SONODEC, is once again an excellent example.

Martini Ziekenhuis Groningen

DEC International flexible duct systems were used for the ventilation systems. Certified duct systems that are available in many models and bores, in standard sizes or made-to measure: the choice is up to you. Their top quality guarantees their durability, long life and top class comfort for the patients and staff.

Hong Kong Shanghai Bank

For this project DEC International supplied tailor-made flexible ducts in special made to measure diameters. These ducts complied with the technical air requirements that apply to rigid duct work. In order to meet the high standards regarding leaks and energy loss, all ducts can be disconnected and reassembled. This is achieved by using a male/female connection with a rubber seal.

München Airport

Durability and comfort were the requirementsthat were set to the technical installations of the ventilation systems. ABB Gebäudetechnik AG chose the Dutch manufacturer DEC International because of its global character, high quality work, its many certified products and the versatility of its assortment. In addition, DEC International stands for durability and safety!

WTC Office Tower Slovenia

The requirements for the technical installations were high; state of the art in the technical field particularly as far as comfort, noise and durability were concerned. DEC International easily met the requirements with its noise-reducing flexible air duct systems called Sonodec. Thanks to the high quality facilities the WTC Ljubljana is part of the first group of fifteen WTC’s that have been awarded the WTCA certificate.

Tokuda Hospital Sofia

The Dutch manufacturer DEC International was selected due to its innovative character, high quality, its many product certificates and the versatility of the assortment. In addition, this durable choice guarantees top-class comfort and a reliable method of working. Thanks to the innovative character, the Tokuda hospital was the recipient of the “Building of the Year” award.

Whitehall Leeds

Flexible HVAC systems have been installed in order to have a flexible response to the needs of users. This is also the case with No 1 Whitehall which is a striking new office building in the heart of Leeds’ business district. Flexibility is the key word that DEC and Direct Ventilation Distributors Limited have running through their veins and DVD Limited has used various products from the DEC range for this “First class” office building.

University Medical Centre.

Hilton Athens

Extension Hôpital Mondor

Hôpital Mondor Due to the Covid crisis the opening has been advanced to help alleviate the need of hospitalsbeds in the Paris area.

Torre Agbar Barcelona

Beijing Capital International Airport

Beijing Capital International Airport is the main international airport serving Beijing. It is located 32 km (20 mi) northeast of Beijing's city center, in an enclave of Chaoyang District and the surroundings of that enclave in suburban Shunyi District.

DEC International was chosen because of its global character, high quality, the number of product certificates and the versatility of the DEC International range. This choice also guarantees durability and safety which are a top priority today.

The Winter Palace - St. Petersburg

The Winter Palace was, from 1732 to 1917, the official residence of the Russian monarchs. Situated between the Palace Embankment and the Palace Square in Saint Petersburg, the palace was constructed on a monumental scale that was intended to reflect the might and power of Imperial Russia. Today, the restored palace forms part of the complex of buildings housing the Hermitage Museum.

Volkswagen production facility - Poznan

The Volkswagen production facility in Poznan, Poland is a joint venture between Volkswagen AG and the Polish car manufacturer Tarpan.

Dzerzhinsky Joint Car Centre

“Strong together” is the motto of the four car manufacturers Ford, Mazda, Rover and Volvo. Strong together also seems to have led to success for our business partner Ventrade and the installation company EVS .
