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 product portfolio for Technology Cooling Systems (TCS)
Looking for well-established fluids for Facility Water Systems (FWS)?
Clariant recommends Antifrogen™ PG 25 for direct-to-chip (D2C) cooling in data centres. It is a ready-to-use, MPG-based fluid purpose-built for Technology Cooling Systems (TCS), offering antifreeze protection down to -11°C, a low toxicity profile, and effective corrosion protection that exceeds ASTM D1384 / ASTM D8040 at 10 times the standard test duration.
Antifrogen™ PG 25 is purpose-built for modern data centres, offering antifreeze protection to -11°C, corrosion inhibition exceeding ASTM D1384 / ASTM D8040 standards, and effective prevention of fouling and microbial growth. Its MPG-based formulation ensures safer handling, while low carbon footprint options support sustainability goals. Backed by Clariant's 75+ years of expertise, it comes with the Antifrogen™ Service for ongoing fluid monitoring and maintenance support.
Ultrapure monopropylene glycol (MPG) offers a low toxicity profile, making it a safe and reliable base fluid for data center cooling applications
Yes. Antifrogen™ PG 25 features a tailored corrosion inhibition system specifically designed for D2C cooling. Antifrogen™ PG 25 fulfils the OCP guideline and exceeds the ASTM D1384 / ASTM D8040 corrosion standard — even when tested at 10 times the standard test duration — enabling maximum equipment protection and lifetime.
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 enable fast and accurate leak detection.
Low carbon footprint versions are available through a mass balance approach or the use of recycled glycol, supporting data centre operators in meeting their sustainability goals.
Clariant offers the Antifrogen™ Service, which includes fluid sample analysis, condition monitoring, and maintenance recommendations.
Clariant provides well-established solutions with Antifrogen™ N (based on MEG) and Antifrogen™ L (based on MPG), both delivering outstanding corrosion and freeze protection. The fluids are available in various water mixture concentrations to ensure tailored antifreeze protection for any facility requirement.
