Antifrogen™ PG25 - Greater chemistry for data centers

36125_original_Clariant_Antifrogen Heat Transfer Fluid solutions for Data Centers2 EN 2026

The challenge: Rising heat loads in Data Centers

Higher processor densities are increasing heat output across data center cooling systems. Conventional cooling methods are no longer sufficient for high-density server environments. Direct-to-chip cooling addresses this by removing heat at the source. It requires a fluid that delivers both thermal performance and long-term equipment protection.

 

The solution: Clariant heat transfer fluids for direct cooling

Clariant's data center cooling fluids are formulated for Technology Cooling Systems (TCS) and Facility Water Systems (FWS). The primary solution is Antifrogen™ PG 25.

Property Antifrogen™ PG 25
Base fluid Monopropylene glycol (MPG)
Toxicity profile Low
Antifreeze protection Down to -11°C
Corrosion standard Exceeds ASTM D1384 (10x test duration)
Industry compliance Fulfills the requirements of the OCP guideline
Format Ready-to-use (concentrates available on request)

  • Protectogen™ C Aqua
    Protectogen™ C aqua is a yellowish, water-soluble, glycol-free liquid which contains a highly efficient combination of corrosion inhibitors. The product is inhibited without the use of nitrite, amine, borate, phosphate, and silicate. The optimization of the corrosion inhibition system was performed without the use of CMR-substances ( C ancerogenic M utagenic R eprotoxic). According to the formulation, Protectogen™ C aqua does not contain any restricted substances as described in the EG-guideline 2011/65/EG (RoHS = Restriction of Hazardous Substances), article 4 §1 like lead, mercury, cadmium, chromate VI, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE).

Looking for well-established fluids for Facility Water Systems (FWS)?

  • Antifrogen™ N
    Antifrogen™ N is a liquid, tinted pale yellow, for use as a heat transfer medium in closed hot water heating systems, heat pumps and as cooling brine in industrial refrigeration equipment. Antifrogen™ N is not suitable for the use in food or pharmaceutical applications. Alternatively, the use of Antifrogen™ L is recommended. The product is inhibited without the use of nitrites-, amines-, borates-, silicates- and phosphates. Read more about Clariant Heat Transfer Fluids Find a distributor
