Heat Pump Sanitiser and Biocide Solution

Kilfrost SF20 is a stabilised, fast acting, sanitiser and biocide solution, especially formulated for use with Ground Source Heat Pump Systems.

Used during pre-commission cleaning of pipework in heating and chilled water systems (as instructed in building regulations BSRIA BG 29/2012 and Building Regs Part L) or to clean and sanitise pre-installed systems already contaminated with biological fouling.

The active ingredient in SF20 is a fast acting oxidising biocide which decomposes to environmentally benign substances. These active ingredients are effective against a wide range of microorganisms including legionella bacteria.

  • Suitable for pre-commissioning chemical cleaning
  • Stabilised fast acting oxidising sanitiser and biocide agent
  • Effective against a wide range of microorganisms including Legionella
  • Fully biodegradable decomposing into environmentally benign substances

KFSF20X1L specifications

Kilfrost recommends a 2 steps chemical cleaning and sanitising protocol:

1. CLEANSING: Kilfrost SF10 Cleaning Fluid or SF11 Cleaning and De-scaling fluid is circulated and flushed to lift soil and physical debris or scale. ONLY REQUIRED WHEN CLEANING AN EXISTING SYSTEM

2. SANITISING: After flushing the cleaning fluid, Kilfrost SF20 should be added and circulated.

Kilfrost SF20 process

– For use as a fast acting system sanitiser: 1 litre of SF20 to every 200 litres of system water.

– In systems to be left stagnant for any significant periods of time: 1 Litre SF20 to every 600 Litre of system water.



For best results, it is recommended that Kilfrost SF20 is circulated for a minimum of 12-24 hours within systems. As per the user guidelines, the system should first be cleaned of all physical debris before adding SF20. After circulation it is essential that the system is then flushed with potable water to remove any remaining SF20 prior to the installation of a heat transfer fluid or circulating water.
