Captures iron-based particulates
Magnetite particulates formed by corrosion and rusting are captured by the magnet even when fine enough to pass through standard filtration.

Magnetic Dirt Separators and Magnetic Filters
Magnetic separators capture circulating magnetite and iron-based particulates from system water with a powerful magnet; these particulates are a leading cause of clogging in exchanger plates and pump wear. At Denfor Endüstriyel, we supply magnetic separators with an easy-to-clean cartridge design and a range of connection sizes for heating and cooling circuits.

Why it matters
What does a magnetic dirt separator do?
It captures iron-based particulates that standard dirt separators cannot fully remove, using a magnet.
Prevents heat exchanger clogging
The narrow channels of plate heat exchangers are especially sensitive to magnetic particulates; a magnetic separator significantly reduces this clogging.
Removable magnet cartridge
The magnet cartridge can be easily removed from the shell and cleaned, making maintenance quick and simple.
Cleaning without interrupting the line
Some models are supplied with isolation valves, allowing periodic cleaning without fully draining the system.
Types
Magnetic separator subtypes
All three capture iron-based particulates with a magnet; what differs is shell design and capacity.
In-line magnetic filter
With a compact shell mounted directly on the pipeline, the standard solution for residential and small-to-medium commercial installations.
- Compact installation
- Economical solution
- Residential/commercial installations
Vessel-type magnetic dirt separator
With a larger-volume shell and a powerful magnet array, used on high-flow industrial lines carrying a heavy fouling risk.
- High capture capacity
- Suited to industrial lines
- Powerful magnet array
Magnetic filter with isolation valves
Fitted with isolation valves at the inlet/outlet; can be isolated from the line and cleaned without draining the system.
- Cleaning without interrupting the line
- Uninterrupted operation
- Easy maintenance
Selection criteria
What data determines the right magnetic separator?
Selection cannot be made without the first two items. The rest determine shell type and fittings.
ParameterWhy it mattersWhat we need from you
Line flow rate
Shell size is determined by the flow rate of the line it is installed on.
m³/h
Fouling intensity
The risk of iron-based particulates is higher in older or renovated installations.
Low / medium / high
Working pressure
Must match the system supply pressure.

Need for isolation valves
A valved model is needed if cleaning without interrupting the line is required.

FAQ
Questions from the field
The questions we encounter most often at the magnetic separator quote stage.
How does it differ from a standard dirt separator?
Standard dirt separators settle heavy particulates by slowing flow velocity; a magnetic separator instead captures fine, especially iron-based, particulates through magnetic attraction — the two complement each other.
In which installations is it especially recommended?
In steel-radiator, older or renovated heating installations, corrosion-driven magnetite build-up is heavier, so a magnetic separator is especially recommended on these projects.
How is it cleaned?
The magnetic cartridge is removed from the shell and the particulate mass on it is cleaned off; on models with isolation valves, this can be done without draining the system.
Does it relate to the heat exchanger warranty?
Some heat exchanger manufacturers may require a magnetic/dirt separator in the installation as a warranty condition; it is advisable to check this requirement before starting the project.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
