ProSpec Auto MUHP5 –
Custom Cabinet Application
The Auto MUHP5 panels can be configured into various custom
configurations. They can also be configured into several sizes
of gas cabinet enclosure. Panel feature and configurations are
dependent on local and international safety codes and gas type.

from side to side. The SP8100 is a touch screen controller that
uses an analog input signals to control the switching of gas from
one side to the other. The analog signal can be from a pressure
transducer installed on the inlet side of the primary regulators, or
from individual scale platforms monitoring weight of a liquefied
gas cylinder. The controller also has an emergency shutdown
feature and monitors 2 general and 6 safety faults. The ProSpec
Auto MUHP5 is an ideal platform for gas cabinet installations.
We can provide this series in a full auto switchover with purge,
2 cylinder auto switchover, or a simple process purge. A single
Auto MUHP5 panel can also be controlled by the SP8100.
