The first deliveries of the enamelled tanks were directed to the agriculture sector for the purpose of the storage of agricultural products - in particular grain, silage and haylage. During several years, this technology has proven practically as the only alternative comparable to the more expensive stainless steel tanks.

Complete implementation of fertilizer storages

We are supplying the liquid fertilizer storage systems based on the customer requirements with the automated withdrawal control, with the fertilizer storage registration option, and with the option of mixing various fertilizer types.

WITKOWITZ ENVI storages for liquid fertilizers

These tanks are intended for the storage of liquid fertilizers with the density lower than 1,400 kg/m³. The tank is equipped with an enamel roof. The bottom is made of welded steel with a protective coating.

The lower part of the shelter is fitted with a DN 700 inspection input and a socket for the connection of the drain piping. The bottom is equipped with a blowdown pipe. An overflow pipe is connected to the upper part of the shell.

The tank is fitted with an access ladder and a service platform. Enamelled tanks for the storage of fertilizers with the density up to 1,400 kg/m³ may be used also for the storage of potable or fire water after some modifications. The tank bottom may be also made of the impermeable concrete.
