Fluids for Commercial & Domestic Heating Systems
Commercial Fluids For Heating Systems
Key Steps when considering the importance of fluids in your heating systems:
Cleansing & Protection
Sentinel X300
X300 System Cleaner is specifically designed for new central heating systems. It flushes out flux and installation debris from new indirect heating systems. X300 cleaner helps to maintain system efficiency and conserve fuel.
- Cleans new heating systems up to 6 months old.
- Powerful, heavy duty cleaning action.
- Removes installation debris, swarf, flux residues & greases.
- Eliminates corrosive flux residues which could give rise to rapid pin-holing corrosion of radiators.
- Prevents harmful copper deposits being left in the system.
- An ideal preparation for X100 inhibitor.
- Supplied in 1L, 10L and 20 litre tubs.
Commercial Fluids For Heating Systems
Sentinel X400
Specifically designed for existing systems Sentinel X400 System Restorer is a non-acid treatment for cleaning older heating systems, restoring circulation to radiators and pipework. A ruthlessly efficient way to eliminate the build-up of magnetite sludge, X400 is the quick and easy way to eliminate cold spots and restore full heat emission. Helps to improve and maintain system efficiency and conserve fuel.
- Eliminates radiator cold spots.
- Can be used in all systems.
- Prepares existing systems for the installation of new boilers, pumps or panels.
- Does not cause pin-holing or leaks.
- Supplied in 1L, 10L, 20 litre tubs.
Commercial Fluids For Heating Systems
Sentinel X200
Sentinel X200 boiler noise reducer is a unique, life-long system treatment for the elimination of boiler noise.
Safe to use in all types of indirect central heating systems, X200 noise reducer will quickly pay for itself in reduced fuel usage.
- Eliminates boiler noise “kettling”.
- Restores boiler efficiency.
- Safe and non-corrosive.
- No need to flush – stays in system.
- Supplied in 20 litre tubs.
Freeze Protection
Some boiler systems require protection against freezing as well as protection from scale formation and corrosion. Sentinel X5OO combines the market leading technologies available in X100 inhibitor with a non-toxic antifreeze in one simple to use product.
Sentinel X500
X500 provides protection against scale and corrosion in all types of indirect heating systems, including those containing aluminium components, whilst preventing freezing.
- Prevents freezing.
- Enhanced scale & corrosion protection.
- Protects all system metals.
- Ensures optimum boiler efficiency.
- Prevents boiler noise.
- Prevents pin-holing.
- Helps prevent the formation of hydrogen gas.
- A simple test kit is available to check levels.
For best results, systems should be cleansed and flushed in accordance with BS7593:2006 new systems and those up to 6 months old with Sentinel X300, existing systems with Sentinel X400 or Sentinel X800 Jetflo.
X5OO should be dosed at a minimum of 20% of total system volume to give frost protection of -8C, a 30% solution will protect down to -13C.
Central Heating Inhibitor
Sentinel X100
Formulated as a multipurpose treatment to inhibit corrosion, scale, boiler noise and hydrogen gassing in all types of indirect heating systems including those containing aluminium components.
Sentinel X100 is suitable for use in all waters, both hard and soft. The formulation is completely non-toxic. 1 litre of Sentinel X100 is sufficient to treat a typical domestic system of up to 10 radiators.
Features and Benefits:
-
- Effectively controls scale and corrosion.
- Complex pH stabilisation pack.
- Helps prevent the formation of hydrogen gas.
- Suitable for all metals including aluminium.
- Easy to handle – Non-toxic and biodegradable.
- Concentration is easily checked with a Sentinel Test Kit or a conductivity meter.
- Supplied in 1L, 10L and 20 litre tubs.
We recommend regular use of the Sentinel X100 Test Kit for central heating systems containing Sentinel X100 Inhibitor as it is a versatile treatment intended to control the risk of corrosion and scaling. The Sentinel X100 Test Kit allows you to check that the dosage of Sentinel X100 inside the system is sufficient to provide protection.
Sentinel SystemCheck is a water treatment analysis service which provides rapid confirmation to installers, engineers, homeowners and authorities that a central heating system has been correctly cleaned and then protected with Sentinel X100 Inhibitor. It can be used during the commissioning of a new system or an older system following the replacement of any components.
Key features
- Independent laboratory analysis.
- Validation of correct cleaning and then treatment with Sentinel X100 Inhibitor.
- Freepost envelope included.
- Full report of results and recommendations provided digitally or by mail.
Sentinel R700 Sanitizer & Biocide
Improved and better performing R700 Sanitiser & Biocide from Sentinel
The new R700 Sanitiser & Biocide is a more stable better performing non-peroxide biocide giving the installer and end user greater peace of mind. Still supplied in 1 litre bottles and available from stock. The new formulation of R700 is still compatible with the existing R500C & R600 heat transfer fluids.
With the technical improvements Sentinel 
have made to the R700 a new test kit will be required to test the biocide levels in a system (the old test kit will not work with the new revised formulation of R700). Please view the attached PDFs and the attached video for technical and usage information:
Sentinel R700 Test Kit Instructions
Normal boiler systems do not generally need to be sanitised with R700 because they operate at temperatures well above 60C and therefore there is a general pasteurisation effect. However, many biomass boilers do not run on a regular basis or they are so big that the temp in some parts of the system remains low, e.g. underfloor heating. – If you think this is the case then using R700 to sanitise is a wise precaution… if in doubt add R700!
- Sanitizer & Biocide
- Typical fill is 1 litre bottle for 300L (new system)
- 3 in 1 advantages
- Pre-treatment steriliser
- Ideal as a system protector if the collector pipes/vertical probes are to be commissioned at a later date to maintain a sterile environment
- Can be added to a system where there exists problems caused by the growth of organisms such as bacteria & fungi. Caused typically by the degradation of thermal fluids or blockages in the pipework system causing unpleasant smells and corrosion of heat exchangers & manifolds etc.
R700 Test Kit
The new R700 Test is supplied in a compact, durable plastic case and contains everything required to analyse the system water both prior to and post application of the R700. This ensures the levels in the system are sufficient before the introduction of the thermal fluid giving both the installer and the system owner piece of mind.
KalGUARD
Sentinel’s commercial electrolytic lime scale inhibitor for all water heaters.
KalGUARD requires no salt to operate and is an environmentally friendly solution to prevent limescale deposits that saves money through greater energy efficiency, reduced maintenance and enhanced performance of water systems. The technology is listed in the Part L Building Regs Domestic Building Services Compliance Guide.
- Only ONE KalGUARD is needed to protect the whole H&C system
- Independently proven water treatment chemistry
- KalGUARD treatment does not decay with pumping or storage, it permanently protects against limescale
- WRAS approved
- Delivers value engineering when installed on rising main, CAPEX savings likely with no detriment
- in performance
- Cleaner taps, showers and valves means bacteria have less places to hide
- Keeps systems clean and protects capital investments
- Where it replaces a brine water softener, it can deliver an ROI in around 12 months
KalGUARD permanent treatment solution is widely specified & installed for major commercial clients.
