Paratherm™ NF Food-Grade Heat Transfer Fluid

Premium NSF-HT1 Mineral Oil-Based Thermal Fluid for Food Processing and High-Temperature Applications

Paratherm™ NF is a high-performance, food-grade heat transfer fluid engineered for use in closed-loop heating systems operating from 24°F to 630°F (−4°C to 332°C). Certified Kosher and Halal, this NSF HT-1 registered fluid delivers exceptional thermal stability, low viscosity, and ultra-clean operation—making it ideal for food and beverage processing, chemical extraction, plastics manufacturing, and renewable energy systems.

Key Features & Benefits:

NSF HT-1 certified – suitable for incidental food contact in food-grade environments
Non-fouling, ultra-pure mineral oil formulation ensures long-term system cleanliness
Exceptional thermal stability minimizes fluid degradation and maintenance
Kosher and Halal certified – compliant for global processing standards
Low start-up temperature of 24°F (−4°C) for fast, efficient system ramp-up
High maximum operating temperature: up to 630°F (332°C)
Flash point over 300°F (149°C) enhances safety
Low vapor pressure and low volatility improve performance and reduce losses

Best Practices for Use:

To maximize fluid life and system performance:

Prevent oxidation by installing a nitrogen blanket on the expansion tank
Implement side-stream filtration to capture particulates and extend service intervals
Monitor fluid condition annually with Paratherm’s ISO 9001:2015-certified lab analysis
Use a 60-mesh Y-strainer upstream of the pump to filter installation debris

⚠️ Safety and Compliance:

Paratherm NF is classified as Aspiration Hazard Category 1. It is not classified as carcinogenic or acutely toxic under OSHA, IARC, or NTP. Proper handling and storage practices, such as grounding during transfers and storing containers indoors, are recommended. Always refer to the Safety Data Sheet (SDS) for full regulatory and handling guidelines.
