AHT Snow Melting
and Ice Prevention
AHT’s Snow-and-Ice
Melting system is ideal
for external concrete,
asphalt, paving stones,
gravel and lawns/turf
(sports fields etc).
Based on our unique and
patented Amorphous Metal
Ribbon Technology they
have significant
advantages over any
other type of hydronic
or electrical
cable-based Snow Melting
and Ice Prevention
systems.
Benefits
Benefits are as follows:
• Larger contact area
with the cold ground or
iced surface
• Reaches the working
temperature faster than
other systems
• Energy saving
• Less costly
• Generates more even
heat
• Extremely simple and
easy to install
• Perfectly safe from
electrical shock hazards
and electromagnetic
radiation
• Reliable and durable
AHT Heating
Elements
AHT
currently supplies two
product families:
• Outdoor underground
heating ribbons or mats
normally at 250 – 500
Watts/m2
• Pipes and Gutters
Freeze Protection/Heat
Tracing ribbon
Both families are based
on a unique design of
fully grounded
heat-tracing cable made
of amorphous metallic
ribbon enclosed in a
mechanically robust
flexible enclosure. The
element is designed to
meet IEEE 515.1 standard
for underground and
outdoor exposed
applications.
Heating
Element Performance
The heating element is
of a fixed wattage. By
using different widths
of amorphous ribbons and
different length of the
element itself, one can
achieve the required
output power per linear
meter/foot. Typically
the high-end limit for
the heating element
power is 62 watts per
meter. This limit
corresponds to more than
5 amps on a single
circuit. The heating
element can be driven by
various power voltage
sources, AC or DC:
110-120, 208, 220-240,
400 and 600 Volts, as
long as the current
limit is met. Low
voltage (below 50 volts)
usage is also possible.
The upper limit working
temperature of the
heating element is 700C.
Geometric
Dimensions
The
heating mats are
designed to cover a
nominal 20% of the
heated area, but the
normal area-covering
density ranges from 15%
to 30%. Other values are
also possible.
Electrical Measures
The normal input power
of each heating mat is
250 – 500 watts/m2. as
specified on each
heating mat label.
Higher input can easily
be achieved by reducing
the spacing between
parallel heating
elements.
