Direct-to-Chip cooling for Data Centers –
Heat transfer fluids by Clariant
Ready-to-use MPG-based coolant for Direct-to-Chip cooling
Clariant provides heat transfer fluids for data center liquid cooling systems. Built on 75+ years of thermal management expertise, our fluids keep Technology Cooling Systems (TCS) running reliably while protecting equipment from corrosion, fouling, and microbial growth. For Facility Water Systems (FWS), established Antifrogen™ solutions are also available.
We offer a portfolio of options for direct-to-chip cooling. For most applications, Antifrogen™ PG 25 is the recommended choice:
- Ready-to-use mixture based on monopropylene glycol (MPG) with a low toxicity profile
- Antifreeze protection down to -11°C
- Protection against fouling and microbial growth
- Fulfills the requirements of the OCP guideline
Available on request: concentrate and customized concentrations, fluorescent tracer for leak detection, and low carbon footprint versions based on mass-balance or recycled glycol.
Antifrogen™ PG25 - Greater chemistry for data centers
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.

Our complete product portfolio for data centers
Clariant recommends Antifrogen™ PG25 for direct-to-chip cooling in data centers. It is a ready-to-use, MPG-based fluid with a low toxicity profile, antifreeze protection to -11°C, and corrosion protection that exceeds ASTM D1384 at 10 times the standard test duration.
Direct-to-chip cooling is a data center liquid cooling method that removes heat directly from processor chips using a coolant fluid. It is used in Technology Cooling Systems (TCS) to manage the higher heat loads of modern, high-density servers.
Antifrogen™ PG25 provides antifreeze protection down to -11°C. Antifrogen™ EG20 provides protection down to -9°C.
Monopropylene glycol (MPG) has a low toxicity profile compared to monoethylene glycol (MEG). This makes Antifrogen™ PG25 a safer handling option for facility teams in data center environments.
Yes. Antifrogen™ PG25 fulfills the requirements of the OCP guideline and exceeds the ASTM D1384 corrosion standard, tested at 10 times the standard test duration.
Yes. Concentrates and customized glycol concentrations are available on request for all Clariant data center cooling fluids.
Yes. A fluorescent tracer option is available on request to support fast leak detection.
Low carbon footprint versions are available through a mass balance approach or the use of recycled glycol.
Clariant offers the Antifrogen™ Service, which includes fluid sample analysis, condition monitoring, and maintenance recommendations. An online calculator is also available for concentration, freeze protection, and physical parameter calculations.
