The magnetic sludge removal device (MSRD) — MOS type are designed for fine purification of water in heat systems and returning cycles, for protection against corrosion and crustose deposits of boilers and internal surfaces of pipelines and their components, as well as to remove from the heat supply system previously formed deposits.
Capacity
The manufacturer produces the MSRD MOS type with capacity from 26 to 7700 m3/hr.
Differences between objective and network MSRD
Objective magnetic sludge removal devices (MSRD) differ from the network MSRD by larger surface of magnets per unit of volume of water passing through the MSRD. As a consequence, the operation of the objective MSRD is achieved more effective water purification (95%) compared with the network MSRD (up to 67%).
Consequently, the use of the objective MSRD advisable for the protection of heat exchangers and heating systems of buildings, and the network MSRD — for cleaning water network systems and security of boilers from deposits.
Installation sites
The MSRD MOS type are installed on the return piping network of boilers, before heat exchangers of circulating cycle and the hot water supply system from the heating side in view of creation of the bypass line to provide possibility of cleaning the MSRD without stopping the system.
Design
The network MSRD MOS type consists of a body equipped with the inlet and outlet nozzles. Inside the body is placed a removable cartridge with partitions, the lower edges of which is put on a removable perforated sheet. Under this sheet is fitted the sludge chamber for collection of big size pollution particles.
These partitions determine the direction and velocity of purifying water flow. On partitions flat ring magnets are installed. The main wall of the magnetic cartidge is made of perforated for the passage of water flow after a labyrinth made by other partitions. The screen filter, located on the entire height of the inner space of the body, prevents the ingress of dirts into the output nozzle. For the purpose of easy work and thorough cleaning of the MSRD, the body cap, partitions and screen filter are made removable to ensuring ease of disassembly.
As additional options are proposed:
- the body cover lifting device;
- the MSRD washer device.
Use of these devices allows the follows:
- to lift the body cover with side shifting;
- to flush the MSRD without disassembly, which significantly reduces time and complexity of service.
Also it is possible to produce the custom-made MSRD according to the Customer’s size.
This is particularly true for reconstruction of boilers, when there is a unique opportunity to install the MSRD instead the standard sump. Moreover, it significantly reduces the cost of reconstruction.
