Protect Critical Circuits in Case of Fire
Worldwide regulations require fire protection for emergency feeder circuits in commercial buildings, public spaces, hospitals, industrial plants and refineries. Critical equipment and processes must continue to operate during an emergency to minimize damage and protect lives.
Setting the Standard in Fire Safety
Historically, fire safety of critical circuits was achieved by running conventional cables behind a heat barrier such as a gypsum board or hollow concrete block; or by embedding the conductors in concrete.
nVent PYROTENAX mineral insulated fire-rated cables are UL listed and can withstand temperatures up to 1850°F (1010°C) for two hours. This built-in fire resistance provides greater protection as opposed to the fire-rating of conventional cables which require heat barrier systems.
Mineral Insulated Technology
nVent's PYROTENAX mineral insulated fire rated cable offers a unique combination of dependability, versatility and performance. Highly compacted magnesium oxide insulation provides exceptional temperature and electrical performance. This inorganic and inherently fire resistant construction features:
- zero smoke
- zero flame spread
- zero fuel contribution
Meets global codes and standards
As codes increasingly call for two hour fire resistance, the demand for a more costly and more complex construction for adequate protection of conventional cables. PYROTENAX fire-rated cables have built-in fire resistance and do not require a fire barrier.
Durable and long lasting
PYROTENAX cables have a proven track record, with millions of feet installed globally.
PYROTENAX cables are:
- Inherently a flameproof barrier
Supplies more power with less space
The cable itself is a fire barrier (built-in fire resistance) and does not require additional construction methods. While conventional cables require heat barrier systems such as gyproc enclosures, or encasement in two inches of concrete, which takes up space, our cables are a built with a fire-resistant barrier, meaning additional construction methods are not required.
