Did you know there are many options to consider when selecting thermal fluids?

  1. Temperature is Everything – match your bulk temperature but also consider film temperature, heater type
  2. Controlling Oxidation – high temperature air exposure can destroy the wrong fluid quickly
  3. Maximizing Fluid Life – short-term or long-term use – invest wisely
  4. Availability is Critical – thermal fluids are often critical to production – how long can you wait for your thermal fluid to ship?
  5. Reliable Service & Support – thermal fluids are maintenance-intensive, but can your vendor help you if there are problem

Operating Viscosity Calculator

Knowing the viscosity of any fluid you are trying to pump is key. As viscosity tends to change with temperature for most fluids, being able to accurately calculate viscosity across a range of operating temperatures is vital in determining if a pump can even handle a viscous fluid at lower start-up temperatures.

Measured in centistokes (cSt) in honor of George Stokes, water at 20°C is used as a reference and has a base value of 1 cSt. To calculate your operating viscosity using our calculator, you’ll need viscosity vs. temperature properties for your fluid along with your operational temperatures.
