Water-Based Heat Transfer Fluid For Low-End Temperatures

MultiTherm WB® is a water-based heat transfer fluid engineered to deliver the desirable low-end temperature performance of synthetic organic and silicone-based fluids. Yet it safely exceeds the properties of familiar aqueous-based glycols to reach operating temperatures to below -5°F (-50°C). It’s non-toxicity combines with the high level of performance to provide a highly effective fluid, posing little risk to the environment, equipment or personnel. Five concentrations of MultiTherm WB® are available to serve a wide range of applications. However, custom formulations are available to satisfy special applications at any temperature between ambient and -80°F (-62°C).

Recommended temperature range:
WB -58: -58°F (-50°C) to 250°F (121°C)
WB -40: -40°F (-40°C) to 250°F (121°C)
WB -22: -22°F (-30°C) to 250°F (121°C)
WB -5: -5°F (-20°C) to 250°F (121°C)
WB+14: 14°F (-10°C) to 250°F (121°C)
