Marvell S10 Silicone Heat and Cooling Fluid (200kg)

Premium Dimethylpolysiloxane-Based Thermal Transfer & Cooling Medium

Product Overview

Marvell S10 Silicone Heat and Cooling Fluid is a high-purity, high-stability silicone oil engineered for demanding thermal control applications across industrial, mechanical and laboratory environments. Formulated using dimethylpolysiloxane, this product delivers exceptional thermal stability, ultra-low pour point performance and excellent resistance to oxidation and degradation, allowing it to function reliably in both high-temperature heating systems and extremely low-temperature cooling circuits.

Its chemically inert, non-corrosive and non-reactive nature makes Marvell S10 suitable for use in temperature-controlled baths, industrial heat exchangers, chiller units, environmental chambers, laboratory circulators and specialised equipment requiring consistent thermal conductivity and long fluid life. The fluid maintains uniform heat transfer efficiency across a wide operational spectrum, ensuring stable system performance, reduced maintenance requirements and extended service intervals.

The 200 kg pack is ideal for industrial users, maintenance teams, equipment manufacturers and service technicians who require a premium silicone-based heat transfer medium for high duty cycles and precision temperature regulation.

Key Features & Benefits

1. Exceptional Low-Temperature Fluidity

With a pour point of ≤ –100 °C, Marvell S10 continues to flow and circulate under extremely low ambient and operating temperatures. This characteristic makes it ideal for use in cryogenic cooling systems, environmental test chambers, pharmaceutical and biotech applications, and any system requiring reliable performance below freezing.

2. Superior Thermal Stability

Dimethylpolysiloxane’s inherent chemical structure provides excellent resistance to thermal breakdown, oxidation and viscosity change. As a result, the fluid maintains consistent heat transfer capability across repeated heating and cooling cycles, contributing to extended service life and reduced fluid replacement intervals.

3. Non-Corrosive, Chemically Inert Formulation

Unlike mineral oils or glycol-based coolants, Marvell S10 does not react with metals, elastomers or system components. It is safe to use with most pump seals, gaskets, stainless steel, aluminium, copper, plastics and synthetic rubbers. This compatibility enhances equipment longevity and reduces maintenance costs.

4. Low Viscosity for Efficient Circulation

At 10 cSt, the fluid offers excellent pumpability and rapid heat distribution. Systems achieve faster temperature recovery times, uniform thermal stability and improved operational efficiency even under high demand.

5. High Purity and Cosmetic-Grade Base

Because the fluid is based on high-purity dimethicone, it produces minimal odour, leaves no harmful residues, and does not degrade into corrosive by-products. This feature is beneficial in cleanroom environments, food manufacturing machinery (non-contact), laboratories and sensitive electronics cooling setups.

6. Outstanding Oxidation and Chemical Resistance

Marvell S10 remains stable in the presence of oxygen, moisture and most chemicals, ensuring safe use in harsh industrial environments. It does not polymerise or sludge under normal operating conditions.

7. Broad Application Versatility

Suitable for both heating and cooling systems, it offers a dual-purpose solution for manufacturers and engineers who require a single reliable thermal control medium.
