We supply Food Grade propylene glycol with or without a corrosion inhibitor package. The food grade formulations are Generally Regarded as Safe (GRAS) for use in the food and beverage industry where the possibility of incidental product contact exists or where a non-toxic coolant is mandated, with typical applications listed as follows;
 
  • Immersion Freezing
  • Defrosting Coils
  • Chilling Beverages
  • Beverage Packing
  • Dehumidification
  • Fermentation Tank Cooling
   
Inhibited blends contain food-grade, non-toxic, multi-metal corrosion and scale inhibitors to protect equipment against corrosion and scale, thus maintaining maximum heat transfer. 

Industrial  Grade formulations were developed for a multitude of closed loop service applications requiring a propylene glycol based coolant operating over a broad temperature range;
 
  • Heat Pump Systems
  • De-Icing 
  • Ice Rinks
  • Natural Gas Heaters
  • Waste Heat Recovery
  • Chilled Water Systems 

 
Our inhibitor packages contain organic or inorganic inhibitors for corrosion protection of single or mixed metallurgy systems.  The additional buffers generate a higher reserve alkalinity level and will ensure the neutralization of organic acids, extending the service life of the fluid. Products can be dyed to provide leak indication.
