Electrically heated glass (request
a quote)
Electrically heated glass is a laminated glass, incorporating almost invisible
electrically-conductive wires. It comprises two or more sheets of glass
interlaid with one or more films of polyvinyl butyral (PVB). This assembly
combines comfort with safety, whilst preventing condensation. Electrically
heated glass is suitable for any situation where there is high moisture content
in the air and where the difference between the internal and external
temperature may lead to condensation risk.
Electrically heated glass is made from laminating two or more lites together. Heating is achieved by a clear resistive conductive coating which is laminated between the lites. The coating can be either on the glass itself or a polyester sheet. The result is a clear heated window without any visible wires or grids.
Voltages: 115, 220 AC 12/24 VDC* (*via AC to DC inverter)
Power: 30-300 watts per Sq. Foot

Electrically heated glass was first developed in World War II to prevent
aircraft windshields from frosting over and obscuring visibility. Since then,
this technology has been become almost universally used in aviation. It has even
reached supermarket freezers, where glass doors must remain clear for customers
to be able to see the merchandise.

Production
In order to electrically heat glass, a microscopic Tin (II) Oxide coating is
applied to a pane of ordinary float glass. This coating is perfectly transparent
and conducts electricity. An electrical current is supplied by two busbars
located on opposite sides of the glass. The electrical resistance of the Tin
Oxide coating produces heat energy. This heat radiates from the glass in the
form of infrared energy. The busbars are typically connected to a power control
unit that regulates the flow of electricity and thus the temperature of the
glass.
Electrically heated glass maintains a steady and consistent temperature across
the entire surface, and heat radiates off the glass in only one direction:
toward the object or area to be heated. In addition, this technology imparts
beauty and elegance to glass. The glass can also be coloured or etched with
designs in order to complement the appearance of a room or appliance.
Groceries
Heated glass is both visually attractive and sanitary, making it ideal for use
with food in a public setting. Since the glass is perfectly transparent, deli
items are in full view of the customers, and remain hot and ready to serve.
Keeping meat and other food items warm improves their taste and prevents
spoilage. This technology is much more efficient and effective than heat lamps,
and is a definite improvement over microwaving cold food just before it is
served.
Electronic Controller
An electronic controller regulates power flow to the heating components, and
thus controls glass temperature. With a simple twist of the dial, the glass can
assume any temperature from approximately 70oF to 350oF. An important feature of
the controller is its automatic fault and glass breakage detection capability
that will automatically shut down the heating circuit if there is a problem. In
addition, the appliance should include a GFCI breaker to guard against ground
faults and leakage currents.
Electrically heated glass windows
Electrically heated glass can also be incorporated into a double-pane Low-E
architectural window unit. With the heating element applied only to the interior
side, the window will radiate warmth into the room no matter what the
temperature outside. This eliminates heat loss, chills, drafts, and frost
problems associated with ordinary glass in cold climates. In warm weather,
heated glass prevents condensation, which helps prevent mould from growing on
the window sill.
Towel warmers
Electrically heated glass can also be employed in the design of towel warmers
for both custom homes and hotels, replacing traditional radiator style units.
The invisible thin film conductor involved in this design is even more efficient
than traditional radiator-type towel warmers. These stylish towel warmers are
comprised almost entirely of glass, yet the glass used in these applications is
never too hot to touch, and it does not contribute noticeable amounts of heat to
the room.
