Water Based Heat Transfer Fluid MultiTherm WB

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 -58°F (-50°C). It's non-toxicity combines with the high level of performance to 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 425°F (218°C)
WB -40:
-40°F (-40°C) to 425°F (218°C)
WB -22:
-22°F (-30°C) to 425°F (218°C)
WB  -5:
 -5°F (-20°C) to 425°F (218°C)
WB +14:
14°F (-10°C) to 425°F (218°C)
