The VT air chiller unit is not functioning as expected and as a result, you cannot reach nominal temperatures below room temperatures as of now.  Although you can operate in the high temperature range, the stability will be poorer than (+/-)0.1 deg. C.   I will address the issue in an expedited manner but the fix is not going to be an immediate one. Part of the issue is the leaky/broken heat exchange system of this rather aging and outdated chiller unit. We will try to replace it once we source a suitable alternate unit.

Thank you for your patience.
