Enhancing System Performance
Avoiding hard water in JEFFCOOL® coolant solutions is crucial. Hard water, laden with calcium and magnesium ions, may lead to scale deposition in the system and potential precipitation of the inhibitor system. In the presence of hard water, it is advisable to opt for distilled, deionized, or boiler condensate water whenever possible. In cases where a suitable water source is unavailable, consider the convenience of pre-diluted JEFFCOOL® formulas for optimal system performance.
JEFFCOOL® E100 / E100N
Description and Usage:
JEFFCOOL® E100 is a 100% inhibited ethylene glycol-based industrial coolant and heat transfer fluid. It is provided as a concentrate and must be diluted with deionized water to achieve the desired freeze point and system compatibility. The recommended dilution range is between 30% and 70% by volume.
JEFFCOOL® E100N is identical in base formulation but includes nitrite to provide added protection against cavitation corrosion, specifically for stationary engines. It is the preferred option for applications such as natural gas compression, oilfield operations, power generation systems, and heavy-duty portable compressors. If you are not operating a stationary engine, the standard JEFFCOOL® E100 is sufficient.
