Expansion tank reflex for heating. Reflex membrane expansion tanks: design and operating features

Membrane expansion tanks from Reflex Winkelmann GmbH are used in water supply and heating systems. They differ reliable design, which is confirmed by laboratory tests and reviews from technical specialists. The tanks meet international quality standards (DIN 1988), characterized by a long service life and impeccable membrane strength. Features of these tanks:

  • Increased wear resistance;
  • Corrosion resistance;
  • Big choice models for any needs;
  • Affordable price.

Expansion Reflex tanks presented by dozens of models. They are divided into two categories - for water supply and heating. Tanks for heating systems are produced in the form of several model lines. They are resistant to increased coolant pressure due to the 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 household ones. They are characterized by a floor-mounted design, for which metal legs are provided. The manufacturer also presented consumers with increased-volume tanks designed for use in heating systems large volume- 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 in separate model ranges. 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.

Buy membrane tanks You can find Reflex in the Teplodvor online store. Buyers can choose from models for heating and water supply systems. Tanks are different the highest level reliability, they come with an official warranty from the manufacturer. We will deliver your purchases throughout Moscow and Russia, we will offer optional equipment for installation of heating and water supply systems.

Excessive pressure in the water supply system negatively affects durability, so compensating devices have been developed. The Reflex membrane expansion tank has excellent operational 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 the general features of the operation.

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.

Application of membrane elements

There are many areas for which you need to buy Reflex products with delivery. The metal case is resistant to most influences and can be installed in almost any room. The membrane is made from butyl, making it ideal for use in unstable conditions.

Contact our company in Moscow and purchase Reflex expansion tanks at prices affordable to everyone. The catalog contains dozens of options that have special performance features.


Reflex expansion tanks are designed to accumulate and store the necessary water reserves, maintain the required pressure in the circuit and protect against water hammer. The tanks of this brand are made from environmentally friendly pure materials and are equipped with an elastic, heat-resistant membrane, which allows the containers to also be used for hot water.

Features and types of water supply tanks from Reflex

Modern models of heating and water supply tanks from Reflex are made from food-grade steel and coated with a polymer layer that protects the material from corrosion. The containers are available for sale in white and red.

For many tank models, the nitrogen chamber is factory filled with gas to a pressure of 1.5 bar. Depending on the configuration, the tank can be equipped with a non-replaceable membrane or a replaceable shell. The containers on sale differ in nominal volume, shape, size and operating pressure ranges - from 3 to 10 bar. Many tanks from the range are capable of storing liquids at temperatures up to 120 °C. Small expansion tanks Reflex, for example, model NG8, can be mounted on a wall in a vertical position. Larger tanks must be installed on the ground using special supports.

All Reflex tanks on the market can be classified as follows:

  • Expanzomats of configuration N have a volume of 200 liters or more. up to 1000 l. These tanks are equipped with a non-replaceable membrane and operate at a pressure not exceeding 6 bar. Containers of this type are distinguished by their durability and long service life;
  • G configuration tanks – these Reflex membrane tanks are equipped with a replaceable membrane. These tanks are available for sale in a wide range of capacities - from 100 to 1000 liters. If desired, the buyer can purchase a tank with a capacity of 5 thousand liters. by reservation. These tanks can be equipped with flanged or threaded connection and are available only in red;
  • Reflex N series membrane tanks are manufactured specifically for structures with solar collector. On sale you can find containers with a volume of 2–600 liters. These tanks are equipped with a permanent membrane and have a threaded connection;
  • Bucky from model range S are capable of operating at a pressure of 10 bar. Models with a capacity of 2–500 liters are available for sale. These tanks are equipped with a permanent membrane and have a threaded connection;
  • Reflex hydraulic accumulators are produced with the DD marking. These devices are developed and manufactured specifically for use in conjunction with heating mechanisms. The buyer can choose a Reflex hydraulic accumulator in white or green. Models have a volume of 8–33 liters. The maximum permissible pressure for operation of the devices is 10 bar.


The advantage of Reflex products is a wide selection of containers. Each buyer can choose a large tank for household use, with a volume of more than 800 liters, or a small tank for household services, with a volume of less than 50 liters.
