Get Added Stability with This Series of Synthetic Hydrocarbons

Product Description

CAMCO® 4628-68 SC, CAMCO® 4628-100 SC, CAMCO® 4628-150 SC

A 100% synthetic hydrocarbon based lubricant including specially designed additives to: protect against corrosion, oxidation, and thermal breakdown; provide seal swell (patented); improve coalescing; and prevent foaming. Used for applications where the lubricant is subjected to certain harsh chemical environments. Major benefits in ammonia applications: pumps, compressor, and refrigeration. This product series has excellent stability with hydrogen, carbon monoxide, and carbon dioxide. This product is 100% synthetic based and unlike competitive products does not contain any mineral oils such as Group II, Group III, or GTL that may result in waxy build up. The result is also improved lubricant film thickness.

Benefits

  • Very low pour point and excellent low temperature fluidity
  • Low volatility—base fluids selected for very low volatility combined with a proprietary anti-misting additive; shown to improve system efficiency through improved oil separation resulting is less fouling of evaporators
  • Low ammonia solubility—carefully formulated to improve system efficiency and reduce wear and limit oil consumption
  • Excellent thermal, oxidation and hydrolytic stability provides cleaner operation, protects equipment, and provides longer service life with improved system efficiency
  • Excellent natural viscosity—temperature characteristics for improved system efficiency and lubrication
  • Superior lubricant film strength reduces energy requirements, maintenance costs and extends equipment life
  • Shear stable—designed to provide extended life with consistent viscosity performance

Applications

  • Lubricant & coolant for ammonia refrigeration compressor applications
  • Especially effective in promoting long life in ammonia compressors and combating corrosion
  • Used in selected hydrogen, CO, and CO2 compressor applications and with certain light hydrocarbon gasses
  • Lubricant & coolant for selected process and gas compressors; typical applications include light hydrocarbons and natural gas compressors
