Reflex expansion membrane brands are modern high-tech containers. These devices protect engineering systems with pumps and shut-off valves against sudden pressure surges. The devices successfully compensate for the thermal expansion of liquids used in systems.
Modern containers used as expanders have similar qualities.
Reflex tanks have the following general characteristics:
The only distinguishing characteristic of Reflex tanks in this line is the nominal volume and shape. Possible options– from 3 to 10 bar. The tanks can be mounted either on the wall or on supports mounted for the tank.
Tanks are produced in various series, each of which has its own indicative qualities.
For example, Reflex DE 100 containers have:
Additional features include:
Tank installation requirements vary and are usually related to quality characteristics systems. The containers have different purposes. This is usually indicated in the accompanying documents.
Reflex hydraulic accumulators can be used as:
Most often, containers are used in private homes as expansion tanks for water heating. Tanks are also used in industrial plants.
For the manufacture of containers, high-quality materials with polymer coatings are used. Standard containers are divided into two parts. Low-inert gas, nitrogen, is pumped into one of them during production. Water can be pumped into the second chamber.
The gas compartment is separated from the liquid chamber by a rubber membrane. The pressure pressure is regulated using a pneumatic valve. It helps to release the excess volume that appears in the water chamber when the liquid is heated. Water can be pumped into the container.
When a certain threshold is reached, a relay is activated, which turns off the pump. When water is drawn from the container, the pressure drops, and the device automatically activates the pump. Hydraulic tanks have varying efficiencies, which are often related to their volumes.
Reflex is a German manufacturer whose products have a lot of positive reviews. They indicate the reliability of the equipment. Users note the strength of the base and the wear resistance of the membrane.
The hydraulic tank has other positive qualities:
Despite the numerous advantages, users note some significant disadvantages of hydraulic tanks. For example, sometimes difficulties arise during maintenance. In heating circulation systems there is a need to constantly monitor pressure, and you need to systematically pump it up. Top part needs to be retrofitted with a valve that will help remove excess air. This air may still end up in the system.
Users often consider the irreplaceable internal membrane to be a minus. But the manufacturer claims that the shell can last a long time and very rarely loses its functional features ahead of time.
Also, many consider the disadvantages high cost products. However, it is worth noting here that the cost of the models is associated with the presence of additional components. At the same time, the most expensive models belong to the latest generation of the S series.
Tanks of 8-140 liters, which are marked NG, will cost users less. By the way, the G series includes expansion tanks with a membrane that can be changed. N series models are the cheapest in cost.

N series variants There are volumes from 200 to 1000 liters. The tanks are equipped with a non-removable membrane, which is considered the most wear-resistant. Practice shows that the service life of such tanks is the best.
NG series variants 35 have a capacity from 8 to 140 liters with a nitrogen chamber of about 6 bar and equipped with a threaded connection. Containers in this series may have various additions, which will determine the final cost of the products.
Calculations of container volume are associated with several parameters:
The correct calculation formula will look like this: V= (VL*E) |D, where:
