What thermal fluids are used in each heating or chilling bath?

All Hubers, except the chiller for the cold trap, will receive Marlotherm SH.

For the cold trap chillers, we recommend a suitable thermal transfer fluid such as 99% isopropyl or ethanol.

While other fluids can be used, we recommend reaching out to Root Sciences Technical Support prior to using a different fluid.

Typically, we recommend replacing the thermal fluid in the feed, residue, and condensing baths every 24 months, and the fluid in the evaporator should be replaced every 6 months.

The fluid in the cold trap should be topped off every month so that it completely submerges the cooling coils in the bath in order to prevent water from condensing on them and contaminating the alcohol.

If water does contaminate the alcohol, it will cause it to appear discolored or hazy, in which case it can be easily drained and refilled with clean 99% isopropyl or ethanol.

My Huber K6 is not maintaining temperature during operation. What can I do to make sure my Huber is operating properly?

The Huber K6 is capable of both heating and cooling. The unit is composed of two halves, a lower cooling bath and an upper heating element with a recirculation pump and controller.

There is a data cable that connects the two halves, enabling the controller to control both halves. Ensure this data cable is snugly secured.

Finally, there is a three-position switch on the lower unit that must be in the “II” position (the upper position) in order for the bottom unit to be controlled by the controller.

Why is my Huber showing the code of “variable speed fault?”

When shutting down Huber heaters and chillers, it is important that the unit’s power switch not be turned off until the unit is fully shut down, or else the valve on the outlet of the unit may become stuck halfway in its throw, somewhere between open and closed.  

To properly shut down a Huber: 

  1. press the stop button in the bottom right of the home screen for the pump icon to become stationary 
  2. the RPM readout below it will read “PUMP” (This means the pump is fully disengaged, the valve has closed) 
  3. power to the unit may now be turned off 

To fix this issue, you may need to re-flash the Pilot One on the Huber unit.
