Secondary Refrigerant Antifreeze

Anti-Freeze	Non Toxic	Biodegradeable	Corrosion Control	Quality Assured



COOLFLOW NTP has been especially formulated for use as a Non-Toxic Secondary Refrigerant Antifreeze in Process Cooling, Refrigeration and Air Conditioning systems. It contains synergistic corrosion inhibitors to protect metals commonly found in such systems. It has been tested in accordance with BS5117 and found to meet BS6580 corrosion standards for mild & stainless steel, aluminium, copper, brass and cast iron. Zinc or galvanised components are not recommended for use with closed loop cooling or heating systems.

COOLFLOW NTP also contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency.

COOLFLOW NTP mixtures are readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.

COOLFLOW NTP is miscible with water in all proportions and can protect RAC systems down to -50°C depending on concentration.

COOLFLOW NTP exhibits super-cooling characteristics and mixtures containing in excess of 50% by volume do not freeze solid, alleviating any concern over possible expansion and burst damage.

COOLFLOW NTP is a clear, slightly viscous liquid. It is mildly sweet to the taste and has a non-pungent but characteristic aroma.

As per BSRIA guide AG 1/2001.1 all pipe-work systems should be clean and free from biological contamination prior to commissioning.

To minimise corrosion air* ingress and exposure should be minimized. A pressurised system is best.
* Oxygen feeds the corrosion process which consumes inhibitors.

Determine the total system volume and add COOLFLOW NTP to the system according to the minimum operating temperature required (see table). The minimum dose of COOLFLOW NTP should not be less than 25% of the system volume and the maximum does not normally exceed 60%. We recommend the use of deionised, distilled or UltraPure™ water for this dilution. Avoid water containing high levels of calcium salts or Chlorides [Cl-].

Health & Safety: Please refer to the associated Safety Data Sheet.

Shelf Life: 3 years when stored in sealed containers out of direct sunlight.

Available in: 5, 10, 15, 20, 25, 205 & 1,000 litre containers and in bulk tankers.

COOLFLOW NTP can also be supplied pre-mixed, as a Ready-To-Use solution.

When measuring the percentage of COOLFLOW NTP in the system use a refractometer.
