What does the full operating window look like?
Discuss both the coldest and hottest fluid conditions, rather than just a target process temperature. The catalogue lists different operating envelopes for each model, and concentration can change physical properties. A freezing point is not a recommended operating limit.
What will the fluid actually touch?
Include metals, seals, hoses and other wetted materials. The catalogue distinguishes several aluminium-compatible variants and some narrower metal-compatibility lists. Family names alone do not establish complete system compatibility.
Is water part of the system — or prohibited?
Some products are water-dilutable, while others must be used directly in dry, closed circuits. Certain low-conductivity models call for ultrapure water; anhydrous families require measures to prevent moisture ingress.
What kind of cooling architecture is involved?
An indirect circulation loop and direct immersion cooling are different applications. The catalogue includes LM-4 data-centre variants, low-conductivity LM-4D, fluorinated LM-14 and dedicated LM-17 immersion fluids. They are not interchangeable by default.
Which safety and application requirements apply?
The catalogue contains both combustible and non-combustible formulations, and identifies several hazardous-chemical families. Food-industry use, electrical insulation and environmental descriptions each require the appropriate supporting documents for the actual product and application.
How will you monitor and maintain the fluid?
Several products call for periodic pH, conductivity or corrosion checks. Salt systems may need inhibitor replenishment; an existing alcohol-water system may call for a compatible additive programme. Confirm the ongoing plan before commissioning.
This is a discussion guide based on the supplied August 21, 2026 Glacier catalogue, not a system design or a safety instruction. The current model-specific technical agreement and SDS take precedence.
