It is, with the transfer, the oldest know-how of Spiroflux.
The dispenser on ground DRD, first of all, was one of the "products headlight" of the company. We manufactured some more than 2500 specimens, and always let us manufacture we, although gravimetric measuring makes him competition cruelly.

Practical, allowing the désachage matter, particularly robust,... it still remains to him of beautiful days in front of him, in France as with export.

The dispensers of colorants, then, such as FD and DCU are very competitive equipment (price/quality) which forges the reputation of Spiroflux.
Sold directly on catalog, they are held in stock (like their spare parts), and thus quickly operational at the customer.
