Class A Ovens
Gruenberg ovens can be designed as Class A ovens to conform to OSHA, NFPA 86A, Factory Mutual (FM) and Factory Insurance Association (FIA) requirements. Class A ovens are equipped with a high exhaust rate: because the heating elements are an ignition source so a high exhaust rate is needed to dilute the volatile vapors below the “lower explosive limits.” As a result, the heating elements’ kW must be sufficiently increased to compensate for the heat loss caused by the above-normal exhaust rate. In addition, for a Class A oven to be energy efficient, the additional kW required must be carefully calculated according to solvent load and operating temperature requirements.

Proactive Downstream Spectrum Analysis
SpectraVizion
SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.
