Krušik - Model Type E -Double Wall Tanks
Double-wall plastics tanks (double-skin plastics tanks) are applied mostly for purposes of storage of so-called dangerous chemicals, primarily for aggressive liquids (high-concentrated acids, alkali and liquid salts) as well as for substances which could endanger the environment in a very critical way. If some leakage occurs out of the inner (storage ) tank, the whole “dangerous” content will be held inside the outer (retention) tank.
The usual practice is to place so-called “leak detector” into the space between the inner and the outer tank. This is in fact the electronic device which detects the leakage and makes the alert by the proper signal.
We mainly produce double-wall tanks of a vertical type, because they are the most comon in practice, but we are also able to manufacture double-skin tanks of a horizontal type. These horizontal tanks can be intended for both underground (burial) or overground installation.
The design of the vertical double-wall tanks is such that they basically consist of two bottoms (the inner and the outer bottom) and two cylinders (the inner and the outer cylinder). The inner tank is intended for long-term storage of substances, while the function of the outer tank is to retent the stored substance in case of an injury of the inner tank, in order to prevent endangering people and the environment.
Our double-walled plastic tanks can normally be equipped with all kinds of standard connections and additional elements like all our other tanks. It is also a practice to install a special sensor in the space between the two mantles – the so-called “leak detector” that signals with a sound and/or light signal if there is a possible leak between the two casings, and we are able to install such a sensor in any of our double-walled plastic tanks at the customer’s request.
Design and manufacturing of vertical double-wall (double-skin) tanks are normalized by EN 12573-2:2000.
Dimensions and volumes of our standard double-wall tanks are principally equivalent to those of our type-B tanks, in case of vertical tanks, and to our type-C tanks, in case of horizontal tanks. At the request of the customer, double-wall tanks can be made with volumes/dimensions combinations that are different than the standard ones.
