Foundational Points for Choosing the Right Fluid

Choosing a thermal fluid? Here are the key factors you’ll need to evaluate before making a final decision.

Managing & Preventing Water in Your Heat Transfer System

The presence of water in a high-temperature heat transfer system is more than an inconvenience—it can also pose serious safety risks.

A Closer Look at Flash, Fire, and Autoignition Temperatures

When selected and applied correctly, heat transfer fluids are extremely safe. Following a few simple guidelines for their use and handling is essential.

Fluid Basics

Choosing Fluids for Systems Over 250 Gallons

This guide is designed to help you make an informed choice when selecting a fluid. While every application is different, it offers enough insight to simplify your decision.

Fluid Basics

Choosing Heat Transfer Fluids for Systems under 250 Gallons and /or Electrically Heated Systems

Systems under a few hundred gallons are often open to the atmosphere, meaning no nitrogen blanket separates the fluid from air at points like the reservoir or expansion tank. These setups require special consideration when selecting fluids.

Fluid Basics

Open Baths and the Challenge for Heat Transfer Fluids

Few applications stress a heat transfer fluid more than open baths. By design, these leave the fluid exposed to air, making oxidation—the leading cause of breakdown—inevitable.

Fluid Basics

Avoiding Oxidation and Thermal Breakdown

When fluid at high temperatures meets air, oxidation begins. This is one of the most common ways fluids deteriorate, usually forming sludge inside the system. Petroleum-based fluids, for example, oxidize once temperatures exceed 200°F, and the rate of oxidation doubles with every 15°F rise.

Fluid Basics

Operating Procedures for Startup and Shutdown

Whatever the system’s design, size, or heat source, a few key steps during startup or shutdown can help extend fluid life and reduce the chances of thermal damage.

Fluid Basics

Maximizing the Life of Extruder Heat Transfer Fluids

Every hot oil used in extruders has a finite life. While the primary factor is the type of fluid, temperature levels and production speeds also play a role in how long the fluid remains effective.
