Description

Glysofor KF is an environmentally friendly, glycol-free low temperature cooling brine with an extremely low viscosity based on an aqueous potassium formate solution.

Glysofor KF serves as an antifreeze, corrosion protection agent and refrigerant (cooling brine) in industrial and food-related refrigeration circuits.

Its optimised viscosity enables energy costs of existing refrigeration systems to be reduced while at the same time increasing their refrigeration capacity; it also enables the dimensions of newly planned systems to be reduced.

Glysofor KF is supplied as a ready-to-use brine (KF15 – KF50) with frost protection values from -15 to -50 degrees Celsius.

Glysofor KF is free of nitrite, amine, phosphate, silicate and borate.

Typical areas of application

Refrigeration and deep-freeze facilities, antifreeze, and corrosion protection agents in water circuits, cooling brine in the food industry.

Further information

Antifreeze

Based on potassium formate, Glysofor KF significantly lowers the freezing point of water and prevents the liquid from freezing, e.g. in cooling systems. Glysofor KF ensures that refrigeration systems remain functional even at sub-zero temperatures. Glysofor KF reliably avoids frost damage to the system caused by bursting effects.

Corrosion protection

Glysofor KF contains an up to the minute combination of corrosion inhibitors which are optimised for the metals normally used in plant and equipment (including copper and aluminium) as well as plastics. Galvanised components of industrial equipment and soft solder must be avoided. Glysofor KF does not attack the materials normally used for seals and gaskets in refrigeration plants. According to our own experience and information in the literature, hemp and normal compressed asbestos seals are resistant as well as

  • Butyl rubber (IIR)

  • Hard and soft polyethylene (LDPE, HDPE)
  • Ethylene propylene diene rubber (EPDM)
  • Polyethylene, networked (VPE)
  • Epoxide resins (EP)
  • Polypropylene (PP)
  • Fluorocarbon elastomers (FKM)
  • Polytetrafluorethylene (PTFE)
  • Nitrile rubber (NBR)
  • Polyvinylchloride, hard (PVC h)
  • Polyamide (PA)
  • Styrene butadiene rubber (SBR)
  • Polychlor butadiene rubber (CR)
  • Unsaturated polyester resins(UP)

Polyurethane elastomers, phenol formaldehyde resins and soft PVC are non-resistant.

Application

Preparation

Any water in the system should be drained as completely as possible before filling the equipment. Small residual quantities and resultant slight dilution can be accommodated by Glysofor KF cooling brine.

Filling

Glysofor KF is supplied in five ready to use variants KF15 to KF50 and can be directly added to the equipment needing filling. The figures in the product name indicate the relevant cooling limit.

Topping up

Only Glysofor KF must be used if the system needs topping up. Glysofor KF must never be mixed with cooling brines based on chlorides or glycols.
