PETRONAS HTO 32

High-Performance Industrial Heat Transfer Fluid

PETRONAS HTO 32 is a premium-grade heat transfer fluid engineered specifically for open and closed industrial thermal management systems operating under high bulk oil temperatures. Formulated with highly refined mineral base oils and enhanced with advanced anti-oxidation and detergent additive technologies, PETRONAS HTO 32 delivers exceptional thermal stability, superior heat transfer efficiency, and long-term deposit control.

Core Applications

• Circulating Heat Transfer Systems: Suitable for both open-vented and fully enclosed heat exchange loops.

• Industrial Processing: Ideal for petroleum processing, chemical manufacturing, rubber molding, textile finishing, and plastics processing.

• Renewable Energy Systems: Applied in solar energy collection, heat transfer, and thermal energy storage units.

Key Performance Benefits

• Enhanced Thermal & Oxidation Stability: Resists thermal cracking up to $305^\circ\text{C}$ in closed systems, minimizing acid formation and fluid degradation.

• Optimal System Cleanliness: Advanced detergency prevents sludge accumulation and varnish buildup on internal heating surfaces, maintaining peak thermal efficiency.

• Extended Equipment Service Life: Compatible with standard industrial seals and elastomers to prevent fluid leaks, seal hardening, and system contamination.

• Broad Operating Envelope: Ensures reliable fluid flow and heat dissipation across continuous operating temperatures ranging from $-4^\circ\text{C}$ up to $305^\circ\text{C}$.
