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. Maintaining system health is essential for ensuring that it runs both reliably and in an energy-efficient way, working towards Carbon Reduction Commitment goals whilst keeping employees or patrons comfortable. The Workplace (Health, Safety and Welfare) Regulations 1992 states that: 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. Sentinel X100 Inhibitor provides heavy-duty protection for commercial heating systems and closed cooling systems against limescale and corrosion. These two main culprits of commercial heating inefficiency can cause cold spots in the system, boiler inefficiency, noisy operation and other problems including system breakdown. The associated ACOP goes on to explain that the ‘temperature in workrooms should normally be at least 16 degrees Celsius unless much of the work involves severe physical effort in which case the temperature should be at least 13 degrees Celsius.’
