VarTech’s new UL-1604; UL-60950 Certified and CSA 213; CSA-60950 Certified all-in-one fully-enclosed NEMA 4X computer/LCDs and panel computers insure intrinsic safety in Class 1/Division 2 hazardous areas where explosive or flammable gasses or vapors could possibly exist. Both the fully sealed and panel mount all-in-one computer models are available with integrated touch screens in 10.4″, 15.0″, 17.0″, and 19.0″ LCD screen sizes. These units require no purge system, giving them a sleek design with a slim profile.

VarTech’s new line of UL-1604; UL-60950 Certified and CSA 213; CSA-60950 Certified computers have Intel processors, DDR2 system memory, a 320GB hard drive and Windows XP Pro operating system (optional Windows 7 or Windows XP Embedded).

VarTech Systems goes beyond UL60950 testing to achieve UL 1604 certification. UL 1604 certification assures safe operation in areas where potentially explosive or flammable substances may be present.

UL 1604 is a higher-level certification awarded only to information technology products that are already UL 60950-compliant. Underwriters Laboratories (UL) assures that products meeting its UL 1604 standard can be safely operated where specific potentially flammable or explosive materials may be present. To earn UL 1604 certification, VarTech computers are tested by Nationally Recognized Testing Labs (NRTLs) to meet six basic criteria: spark ignition, temperature rating, warning markings, I/O mechanical integrity, water ingress and dust penetration testing.

VarTech Systems has upgraded its DiamondVue and Crystal Vue series of industrial LCD monitors with many new features and improvements.

Unlike many of who claim to build rugged industrial monitors, VarTech Systems does not “repackage” commercial grade off-the-shelf LCD monitors meant specifically for use within very controlled environments (home, office, retail), but rather individually sourced or company designed modules engineered especially for use throughout harsh industrial applications which will be used running 24 hours a day, year round.

LCD Improvements Include:

1. Use of Next Generation Industrial LCD Cell ( We do not use commercial home/office grade LCD panels);
2. Greater energy efficiency;
3. Improved optical performance;
   
4. Improved environmental performance;
5. Improved image reproduction;
6. Wider color gamut;
7. Higher image definition;
   
8. Improved backlight and LCD cell reliability;
   
9. Improved MTBF

Electronics – We do not use “commercial” grade controllers, but rather true “industrial” grade devices.

1. More robust ruggedized designs;
2. Improved safety and compliance standards;
3. Improved environmental performance;
4. Improved product standardization;
   
5. Greater energy efficiency;
6. Improved MTBF (Mean Time Before Failure).

Mechanical

1. Superior ruggedization – best throughout the industry;
2. Machined 6061 T6 Aluminum NEMA 4 (IP65) or 316 Stainless Steel NEMA 4X (IP66) Front Bezels;
3. Lighter weight without compromising ruggedness;
4. More customizable available options for our customers.

New Features and Improvements for the CrystalVue Display series:

Sunlight Readability

1. The integration of the latest Light Emitting Diodes (LED) instead of traditional CCFL backlights which:

• Provides an LED array allowing for light-source redundancy;
• Provides a no risk scenario of backlight hard failure;




• Are virtually instant on with little or no “warm-up” common with traditional CCFL backlights;
• Superior electrical to light efficiency allows our LED backlit LCDs to provide sunlight readability while consuming significantly less power than that of traditional CCFL backlit panels;
• Provides for improved shock & vibration protection and improved brightness uniformity over CCFL backlights;
• Provides far greater backlight life expectancy, over 70,000 hours.

2. Advancements to recycling of what would be wasted off axis light and then redirecting light towards the viewer;
3. An innovative advancement to the optical stack;
4. Advancements to the reflecting and recycling polarized light which under normal circumstances 50% of the backlight output would have been absorbed into the LCD and subsequently wasted;
5. The use of a multilayer, ultra-high reflectivity, mirror-like optical enhancement film that is used as a very efficient light guide and cavity reflector with a reflectivity of 98.5% across the visible spectrum which provides a brighter more efficient display;
6. Far more efficient use of ambient light;
7. Improved transmissive ratio of the transmissive field and the efficiency of the backlight(s);
   
8. Greater optimized balance between brightness and reflection ratio;
9. VBOND – VarTech’s unique proprietary optical bonding process is now STANDARD – benefits include:

• The best reduction of ambient light washout compared with that of any other commercially available enhancement technology;
• Offers superior ruggedization by enhancing the display durability under vibration and shock extremes;
• Significantly improves reflective light loss;




• Increases extrinsic contrast ratio significantly;
• Eliminates the air-gap between the LCD and the touch screen or protective window which:

1. Prevents the “greenhouse” effect;
2. Prevents fogging and moisture build up;
3. Eliminates any contamination from dirt and/or other obstructive particles.
