AHT outdoor heating ribbons

are designed and manufactured to withstand harsh external conditions and meet the highest international safety standards.
The outdoor heating ribbons are based on a unique design of fully gounded heat-tracing amorphous metal ribbon heating element enclosed in a mechanically strong but flexible enclosure. They meet the IEEE 515.1 standard for undergound and outdoor exposed applications.
 
As such the AHT outdoor heating ribbons have been globally approved by Intertek and proudly carry the ETL mark.
 
AHT products have been tested and have been found to have negligible electromagnetic radiation, far below the minimum requirements of the applicable standards. As such they have been approved by Nemko and have the appropriate certification.
 
All AHT products when installed according to the installation instructions outlined in the appropriate AHT installation manual, are perfectly safe and achieve the highest performance levels.

AHT Snow-and-Ice Melting systems are based on our unique amorphous metal ribbon heating technology. They have significant advantages over other types of hydronic or electrical cable- based Snow Melting and Ice Prevention systems.
 
AHT currently supplies three families of products:

  • Underground – U Outdoor heating ribbons
  • Roof and Gutter – G Outdoor heating ribbons
  • Road – R Outdoor heating ribbons

 
Among the benefits of the AHT Snow Melting and Ice Prevention systems are:

  • Wider contact area with the cold ground or ice
  • Reaches the working temperature faster than other systems
  • Energy saving
  • Generates more even heat
  • Less costly
  • Extremely simple and easy to install
  • Reliable and durable.

 
Intended for use under concrete, asphalt, paving stones, gravel and natural or artificial grass to heat sportsfield of all types such as football, rugby, tennis, golf etc. as well as for agricultural applications. 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 70C.
 
All AHT Outdoor heating ribbons 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 standards for underground and outdoor exposed applications and are fully certified and listed by INTERTEK and proudly carry the ETL mark.

AHT SNOW MELTING AND ICE PREVENTION

AHT Snow-and-Ice Melting-system är baserade på vår unika Amorphous Metal Ribbon värmeteknik. De har märkbara fördelar jämfört med andra typer av vattenburna eller elektriskt kabelbaserade snösmältnings- och isskyddssystem. AHT levererar för närvarande tre produktfamiljer:
·   Undermark - U Outdoor heating ribbons
·   Tak och takrännor - G Outdoor heating ribbons
Vägar - R Outdoor heating ribbons

BENEFITS

Fördelarna med AHT Snow Melting och Ice Prevention Systems är bland annat:
·   Bredare kontaktområde med den kalla marken eller isen.
·   Når arbetstemperaturen snabbare än andra system
·   Energi sparande
·   Genererar mer jämnare värme
·   Mer ekonomisk
·   Extremt enkel och lätt att installera
Pålitlig och hållbar.

Avsedd för användning under betong, asfalt, stenläggning, grus och natur- eller konstgräs för att värma upp idrottsplatser av alla typer som fotboll, rugby, tennis, golfbanor etc. samt för användning inom jordbruket. Värmeelementet kan drivas av olika strömspänningskällor, AC eller DC: 110-120, 208, 220-240, 400 och 600 volt, så länge strömstyrkan inte överskrids. Lågspänning (under 50 volt) är också möjlig. Värme elementets övre arbetstemperaturgräns är 70 ° C.

Alla AHT Outdoor heating ribbons är baserade på en unik design av jordad värmekabel tillverkad av amorphous metallic ribbon som är inneslutet i ett mekaniskt robust, flexibelt hölje. Elementet är utformat för att uppfylla IEEE 515.1-standarder för undermark och utomhusexponerade applikationer och är fullt certifierade och listade av INTERTEK och bär stolt ETL-märket.

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 70°C.

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.
