Original Press Release:

Rite-Hite Pioneers New Door Safety Category with LITESPEED(TM) HZ

New high-speed door can operate around combustible dusts

The LiteSpeed™ HZ joins the Rite-Hite family of high-speed doors as one of only two doors in the industry that is UL listed for hazardous rated environments. Rite-Hite’s FasTrax is the only other door with this distinction.

The LiteSpeed HZ has a Class II, Division 2 listing from UL, carrying a Group Code G and Temperature Code 6. The listing means it can safely operate in facilities where combustible dusts (such as flour, grain, wood, plastic or chemicals) are not normally in the air, but can be present. All electrical components are enclosed in a UL Type 4X (NEMA) or DustTight enclosure. Those components include photo eyes, encoder, junction box near the motor, and the motor and brake, making it the only door rated as a whole.

Its roll-up design translates into a small physical footprint in the workplace and operating speeds of up to 65” per second. Using available safety presence sensors, personnel working near the door are likely to avoid a collision. However, if the LiteSpeed Clean is bumped or impacted, the TRUE Auto Re-feed™ will automatically reconfigure the door back on its tracks. This eliminates a potential breach in a clean room environment and the downtime and costs associated with repairing a traditional door.

In addition to its ability to function well in clean environments, the LiteSpeed HZ also comes with an array of safety features. Most notably, the bottom has soft breakaway, which provides a higher degree of protection for product, personnel and equipment. An optional full-width vision panel allows workers to see what’s on the other side of the door. A reversing slack sensor can reverse the door’s course if an obstruction is sensed.
