Calcium Chloride Solution or Calcium Chloride Refrigeration Brine Grade
A Brine may be defined as liquid of low freezing point used in transmission of refrigeration without change of state. The brines commonly employed in refrigeration are Calcium Chloride CaCl2 and Sodium Chloride. Sodium Chloride is cheaper but cannot be used below minus 15C. CaCl2 of commercial grade can operate satisfactorily up to minus 40C. Use of CaCl2 above 33% should be avoided as it results in crystallization resulting in reduced efficiency. The CaCl2 selected should be adjusted to pH of around 8 and it should be free from free-acid and dirt. Colored material should not be used as it results in corrosion and scaling of the tubes. For the same reason by-product CaCl2 is not desirable as it contains Organic Chlorides which may break into Hydrogen Chloride.
