| Answers |
|
| What is the crystal material used? |
| Our Crystal range of Thermographic Inspection Windows use a proprietary material called CLIRVU. This material has been designed to operate with short-wave, medium-wave and long-wave infrared cameras, and is able to withstand an internal arc blast. |
| I have heard that crystals absorb water - will these as well? |
| No. The CLIRVU crystal material will not absorb water or degrade. This material can withstand over 20,000 cleaning cycles and repels dust due to its anti-static capability. CLIRVU is not hygroscopic. |
| If I install these Thermographic Inspection Windows, will I void the UL listing or warranty? |
| Typically speaking, warranties will expire eighteen months from the date of shipment, or twelve months from the data of commissioning. If your switchgear is more than two years old, then there shouldn't be any issues with the warranty. |
| What is the Field of View? |
| The achievable Field of View is approximately six times the cabinet depth. For example: if a cabinet is six inches deep, the diameter at the base of the Field of View 'cone' is thirty-six inches. |
| How long does it take to install these? |
| The installation process in standard switchgear can be less than ten minutes. In addition, we supply an installation kit (available to either purchase or rent), which can reduce this time further (particularly ideal for large scale installations). |
| What are the gaskets made out of? |
| The gasket material is silicone. It has a continuous maximum operating temperature of 250°C. |
| Can we remove the security impact covers? |
| No. While these covers may be removed by authorised personnel for inspection purposes, they must be returned and locked after the infrared survey has been completed. |
| What is NFPA 70E, and why do I need to worry about it? |
NFPA 70E is the standard for electrical safety in the workplace, and is also an OSHA recognised industry practice. If you are performing infrared surveys with equipment live and exposed, then you are running the risk of arc-flash related injuries or worse. This is also true even if you do not remove the covers directly, or even if you do not break the plane of the door during the inspection. |
