Sundries
At County we stock a wide range of plumbing and heating sundries, some of which are shown below.
Sentinel X100
A general purpose treatment for total protection against scale and corrosion in all types of indirect central heating systems, including those containing aluminium. Will extend the life of the system, and ensure maximum efficiency and minimum fuel usage. Once added, Sentinel X100 never needs to be replaced unless the system is drained down.
- Effectively controls scale and corrosion
- pH neutral formulation- easy to handle
- 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
Sentinel X200
A unique, life-long system treatment for the elimination of limescale and boiler noise. Safe to use in all types of indirect central heating systems and will quickly pay for itself in reduced fuel usage.
- Restores boiler efficiency.
- Eliminates kettling.
- Safe and non-corrosive.
- A much faster, simpler method of de-scaling.
- No need to flush - stays in system.
Sentinel X300
Flushes out flux and installation debris from new indirect central heating systems and those up to 6 months old. An essential remedy against scale and sludge.
- Powerful, heavy duty cleaning action.
- 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
Sentinel X400
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.
- Restores circulation to part blocked radiators.
- Can be used in all systems.
- Prepares existing systems for the installation of new pumps.
- Does not cause pin-holing or leaks.
Sentinel X500
Provides protection against scale and corrosion in all types of indirect heating systems, including those containing aluminium components, whilst preventing freezing. It is effective at preventing hydrogen gas production.
The product is not suitable for heat transfer circuits of solar energy collector panels in which temperatures may exceed 200C or be subject to periods of stagnation. For best results, systems should be cleansed and flushed in accordance with BS7593: new systems and those up to 6 months old with Sentinel X300, existing systems with Sentinel X400 or Sentinel X800 Jetflo.
The dosage of Sentinel X500 Inhibited Antifreeze will depend on the level of frost protection required. One 20L pail of Sentinel X500 added to a typical domestic system of 8 to 10 radiator panels will provide the minimum concentration of corrosion and scale inhibitor and also protection from freezing down to approximately -6°C. Two 20L pails will provide protection to -20°C.
