FTK Fine Filter System - Available to rent or buy

Inline water treatment via use of the FTK fine filter is a safe method that has proven itself many times to adjust the water quality in heating/cooling systems to the desired level without having to replace the existing system water or interrupt system operation.

Heavily silted systems can be cleaned via the FTK fine filter while they remain fully operational.  Filtering down  to as small as 1 micron and assisted by a high powered neodymium magnet the FTK provides a quick approach to system cleaning.  

Made from stainless steel and combined with a 8m3/hr pump the FTK system can operate up to 95 degrees & up to 16 bar system pressure making it ideal for any installation.

Fitted with an internal pressure switch which automatically turns the pump off once the filter has become blocked the FTK filter is safe to leave in operation while unattended. 

The FTK can be used in conjunction with our PUROFILL VA to condition the existing system water during the renovation period. 

Fine Filter Cartridges
Fine Filter Cartridges

Highly effective filters cartridges are available in 1, 5,15 & 40 μm. The fine filter cartridges dramatically reduce the time taken to clean existing systems.

Automatic Shutdown
Automatic Shutdown

Fitted with a pressure switch the FTK fine filter automatically switches its self off once the cartridge has expired. Allowing users to leave in operation safe in knowledge that the system will turn its self off if required.

The Facts 

If a corrosion promoting environment occurs within a system the water quality will  become a problematic & as soon as a new appliance is installed into an existing system it is likely to be contaminated via pre existing corrosion.  

The water quality in existing systems is likely to reduce the new appliances life span, instantly reduce efficiency, impede  its reliability, not to mention the system as a whole. It is also unlikely to comply with manufacturer's specifications, which can invalidate the warranty. There is a risk of reduced efficiency  due to limestone formation or layers of magnetite/sludge which spreads through the system like a cancer effecting every component. 

The advantage of in-line heating water treatment is the system water quality can be prepared without interrupting the system operation, flushing or exchanging the system water and introducing fresh oxygenated water which promotes corrosion. 

Stagnant water in areas with poor flow, which may not have been accessible or existing deposits that dissolve in the newly filled heating water can gradually be filtered out as these will greatly effect the quality of the newly filled systems. When the water quality is checked, which usually takes place after the system has been in operation for 8 weeks, deviations from the quality of the treated fill water are found. A renewed correction of the water quality is often necessary in these cases & for these reasons the use of FTK fine filter in conjunction with PUROFILL VA is particularly appealing. 

The uninterrupted heating water treatment in the circulation process, also called inline desalination or inline water treatment, is usually used for the following measures:

  • Commissioning rehabilitation of silted underfloor heating

  • Removal of silt and circulating impurities from the heating water

  • Removal of disruptive substances, e.g. oil in the heating water

  • Lowering the heating water total hardness

  • Heating water desalination during operation, thus lowering the electrical conductivity of the heating water

  • Correction of the pH value

  • Targeted removal of corrosive salts from the heating water

Cleaning & Preparation For Existing  Heavily Silted Systems

Sludge and incrustations due to corrosion or residues of hardening salts can lead to considerable problems in heating systems. Some sources speak of a deterioration in heat transfer of up to 20% due to insulating deposits. This can result in increased energy consumption and even failure of entire heating circuits.

Corrosion is the cause of sludge formation in the heating system, which is triggered by the constant influx of oxygen. Sludge-filled heating systems must be flushed out so that the heat transfer of individual heating circuits works optimally again.

It is not just sludge/magnetite which requires flushing from existing systems. Residues of old water or oxides and hardness salts can adversely affect the new water quality. Therefore these residues should be rinsed out as best as possible before refilling the heater.

OXILIN P-20 IMPROVES & ACCELERATES THE  FLUSHING PROCEDURE

 

Existing deposits are often very sluggish, stick firmly and are therefore difficult to flush out of the system. The use of  OXILIN P-20 helps to remove the toughest of debris. 

 

OXILIN P-20 has a cleaning and dispersing effect which means that on the one hand deposits are loosened and on the other hand they are also kept in suspension. This combination of effects significantly improves the result of the flushing procedure.

OXILIN P-20

  • Thanks to its optimal product properties is an effective support in cleaning every silted heating system and other water-carrying systems.

  • Dissolves stubborn dirt, which improves heating flushing.

  • Brings even inert corrosion particles into suspension, whereby they can be rinsed out.

  • Non aggressive to metals and as an alkaline cleaning agent with a pH value of 8-9 is ideal for heating systems.

  • Safe for people and the environment thanks to the most modern mixing components.

 

Area of application OXILIN P-20 is particularly suitable for use in water-bearing systems in which several different materials such as steel, non-ferrous metals and light metals are present together. Due to its dispersant component, deposits are broken down on the pipe walls and solids are kept in suspension. Due to the thermal and chemical stability, an excellent long-term effect is guaranteed, which makes OXILIN P-20 particularly suitable for cleaning heating systems in the renovation phase.

According to the EC directive of September 18, 1979 (Annex VI), OXILIN P-20 is not classified as harmful to health.

 

Dosage Rate
Dosage Rate

The dosage level of OXILIN P-20 is calculated according to the water content of the heating system and should be 1000 to 5000 ppm (0.1 - 0.5%) of the system volume for system cleaning. If the system volume is unknown, approx. 20 litres of water content per kW of heating output should be assumed.

Exposure
Exposure

OXILIN P-20 must remain in the heating circuit for at least 24 hours with the circulation pump switched on. To optimize the effect, we recommend an exposure time of 10 days. After the exposure time, OXILIN P-20 must be rinsed out of the heating system together with the system water. When rinsing out, compare the pH value and conductivity of the incoming and outgoing water.

Suitable For All Materials
Suitable For All Materials

OXILIN P-20 can be used with typical materials such as those found in heating and cooling systems without hesitation. The compatibility was tested on common sealing materials (e.g. hemp, elastomers, synthetic fibres), plastics (e.g. PE, PB, PP, PTFE) and metals (e.g. steel, copper, brass, stainless steel, aluminium).
