Operating pressure in the reflex expansion tank. Reflex expansion tanks. Features and types of water supply tanks from Reflex
Excessive pressure in the water supply system negatively affects durability, so compensating devices have been developed. The Reflex membrane expansion tank has excellent performance properties, including ease of installation and durability. Each presented vessel complies with current GOSTs, so it is perfectly suitable for pipelines even in large-scale heating and water supply systems.
Construction work
Before purchasing a membrane container from the manufacturer Reflex, you need to consider common features work.
The division is carried out into 4 stages:
- normal conditions exclude increased pressure in the network;
- an increase in temperature in the system provokes an increase in pressure;
- an increase in the indicator becomes the reason for the spontaneous connection of the Reflex container to the water supply;
- when the liquid cools, the vessel pushes it back into the pipeline.
Ordering Reflex products allows you to be confident in the durability and stable operation of the system.

Expansion tanks Reflex is represented by dozens of models. They are divided into two categories - for water supply and heating. Tanks for heating systems are produced in several model lines. They are resistant to high blood pressure coolant due to uniform distribution of the load over the entire surface of the membranes. Some of them are designed in welded housings, the membranes in them are non-removable.
One of the most popular lines in the world is Reflex N. These tanks are equipped with non-removable membranes and are resistant to wear. Due to their small volume, they are used in small heating systems, including domestic ones. They are characterized by a floor-mounted design, for which metal legs are provided. The manufacturer also presented consumers with tanks of increased volume, designed for use in large-volume heating systems - many of them are equipped with removable membranes. Separately presented is a line of tanks for systems with solar collectors and a line of tanks for wall-mounted gas boilers (the latter are distinguished by their compact design and flat body shape).
Reflex membrane tanks for water supply needs are presented separately model series. They are used in conjunction with pumping and water heating units, as well as with hydropneumatic accumulators. Buyers can choose from models with replaceable and non-replaceable membranes that can withstand high loads. Another type of membrane tanks from the Reflex company are hydrodynamic shock compensators. They are designed to absorb water hammer in water pipes. Their installation is carried out directly in front of the connected consumers - these are washing and dishwashers, water heaters and indirect heating boilers.

The German company Reflex offers the widest range of expansion tanks for water supply, water treatment and heating on the market. They are closed containers with a rubber membrane that separates the gas zone (nitrogen cushion) from the liquid compartment.
Designed to accumulate and store a reserve supply of water (made from environmentally friendly materials that are safe for human health), maintain pressure in the circuit, and prevent water hammer. For the heat supply system, any Reflex expansion tank (expanzomat) is equipped with an elastic heat-resistant membrane. Its main task is to serve as a damper and maintain the necessary pressure. When heated, excess liquid collects inside, which, when cooled, returns to the circuit. Also, it performs protective function from water hammer.

Customers' opinions
“I installed Reflex NG 18 on the return pipeline heating system in front of the circulation pump. I took it with a small reserve. There were doubts about the non-replaceable membrane, but it has been working without problems for about 3 years.”
Dmitry, Moscow.
“The water supply system in the cottage was arranged as follows: borehole pump supplies water to storage tank Reflex 300 l with relay. Next to the filter rough cleaning and to the house. The relay is set to oscillate from 2 to 4 atm. The tank volume is completely enough for all needs. It has been functioning without repair for more than 3.5 years; a specialist performs a preventive inspection only once a year.”
Vasily, Nizhny Novgorod.
“There was a need to change the heating in the house, the system is about 180 liters. Installed circulation pump and a membrane tank. I wanted one with a replaceable diaphragm, but I couldn’t find one for the required volume. I decided to trust German quality- purchased Reflex N 18 white. I’ve only worked for 2 heating seasons so far, no complaints.”
Timur Kireev, Chelyabinsk.
"For autonomous system water supply, we bought a pump with a capacity of 3.5 m3/h and an expansion tank model Reflex DE 100 about a year ago. We chose it for its removable membrane with antibacterial properties. It’s completely enough for our family (4 people), although we like to splash around in the shower. The equipment is functioning properly, everyone is happy.”
Kirill, Volgograd.
“The length of the wiring around the house is about 40 m of 2-inch pipe, 50 sections cast iron radiators. I installed a closed German Reflex tank of 18 liters. The system works like clockwork, without failures.”
Mark, Yekaterinburg.
