Setting the industry standard, HUB free standing
crucible furnaces combine superior efficiency with easy maintenance
and crucible change. Customers claim 30-40% and more increased
efficiency after changing to MU furnaces from day tanks.
Our furnaces are designed to last. The furnace
design allows the front of the furnace to be opened up. This
design is a very common industry standard as it allows easy
crucible change and furnace interior maintenance. We have been
building these furnaces for more than 20 years and all of our
furnaces are still operating, producing glass every day. With
proper care, these furnaces should last a lifetime
No furnace system should be operated without proper training and safety precautions. We are committed to safety. Our transformer system provides galvanic isolation—there is no direct connection between the power line and the heating element. The result is a system that has no significant voltage difference versus ground. You will not be hurt if are grounded and accidentally touch an energized element with your pipe or ladle.

More About Our
Freestanding Crucible Furnaces
Each furnace is shipped with a mold for casting
a new gathering port block and a spare door. The gathering
port block is typically replaced at every 3rd or 4th crucible
change, depending on wear. A manual with step-by-step instructions
and pictures detailing the process of changing the crucible
and routine maintenance is included with each furnace.
Crucible life is easily one year. We recommend
a yearly shut down for crucible change and maintenance; however,
many customers have claimed 20 months and more of continuous
use.
The interior of these furnaces is a cast high
alumina lining. This is an incredibly rugged system that is
backed up with a minimum of 10” of 12 lb./sf fiber
insulation. The heavy insulation and thick refractory lining maintain even heating
and allow quieter operation utilizing
smaller burners.
Furnaces are delivered on heavy duty bases,
heavy steel exteriors and include levelers. Wheels are also
standard.
As with all of our equipment, these furnaces
are designed to accommodate a wide variety of burners and control
systems. Combustion system prices vary depending on size, type
of burner, flame safety requirements and the level of automation
desired.
This is an excellent opportunity for those of
you who want to build a great furnace, save money, and learn
more about building equipment.
The step by step instructions (with 62 photos)
detail the process of building a furnace. These are the same
steps that we use here at the HUB. The book contains complete
drawings of the refractory and metal parts. There is a comprehensive
list of refractory and materials needed as well as lists of tools, supplies,
and vendors to help make
procurement and preparation simple. Rentals include backup support—it couldn’t
be easier.
HUB sells high quality refractory and has stocking
distributors nationwide. See Refractory & Crucibles.

Electric Furnaces
To better meet our customers’ needs, we have decided to add electric packages as an option for furnace heating. The furnace is our same tried and true free standing crucible design with moly disilicide elements instead of a burner.
We have selected Duralite as a vendor for these
packages. Duralite has been providing electric heating systems since 1946 and has experience in the glass melting field. They offer options that are very safe and extremely reliable. We welcome your inquiries about our electric furnaces, and we would be happy to answer any questions and provide you with a quote.
HUB now offers two standard size Day Tanks (DT)
designed for efficiency and durability. HUB’s Day Tanks
incorporate superior insulation. Although these furnaces are
not as long lasting or quiet as our pot furnaces, they are more
efficient and quieter than most day tanks. Like all HUB furnaces,
HUB’s tanks provide a shelf at the door. Our standard sizes
are listed below. In addition, we also build custom tanks to
suit individual production requirements.
