The differences between commercial UPS & industrial UPS. Over the life of a facility an owner would need to buy and install (3) commercial UPS systems and (4) vrla battery plants compared to the equivalent (1) industrial UPS with a matching NiCad battery. Industrial might cost more up front but comparatively speaking I cannot see how an airport or water treatment facility would go any other direction.

1. THE INDUSTRIAL UPS DIFFERENCE
WHAT SEPARATES AN INDUSTRIAL GRADE
UPS FROM A COMMERCIAL GRADE UPS?

2. COMMERCIAL UPS APPLICATIONS
• Data Centers
• 911 Call Centers
• Banks / Financial Institutions
• Pharmaceutical Labs
• Schools
• Office Buildings
• Medical Equipment (MRI)
• Phone Switches
• POS Devices

3. INDUSTRIAL UPS APPLICATIONS
• Refineries (Steel, Oil, Gas, Chemical)
• Railroads – Signal, Communication
• Airports
• MWRD and DOW Facilities
• Utilities/ Power Generation Stations
• Military Bases and Installations
• Nuclear Power Plants
• Oil and Chemical Pipelines

6. INDUSTRIAL UPS LAST 3X LONGER
• Industrial UPS - designed for 30 year operation, minimum of 20
years before first component replacement
• Longer life cycles achieved through high grade components
being more lightly loaded. 60% loading on average, 70% max
loading is required
• Redundant components including caps, power supplies, fans &
SCR’s, increase system reliability while extending life
• If specified correctly and scheduled parts are replaced at year
20, a 30 to 40 year installation life is not uncommon. Many
Steel, Oil/Gas & Power Gen facilities in the USA see these 30 +
year installations

7. INDUSTRIAL UPS VS. COMMERCIAL UPS
1. Each Industrial UPS is Designed & Built Project
Specific
2. Rectifier Filters Reduce DC Ripple, Extending
battery life
3. Rectifier/Charger Sections are Designed for a
Specific Battery (such as NiCad) and sized for
Long Run Times
4. Input and Output Isolation Transformers Standard
5. Circuit Boards are Conformal Coated for
Protection

8. INDUSTRIAL VS. COMMERCIAL UPS SERVICEABILITY
• Industrial UPS manufacturers anticipate the owner maintaining and
servicing their own equipment and will support them in doing so.
• Replacement parts for industrial UPS are made available for a minimum
of 20 yrs. While commercial parts are available for a maximum of 10
years
• Service manuals, factory support and software updates are all made
available
• Larger footprints make servicing easier and safer. In addition to
improved air circulation and heat rejection.
• Lower DC bus voltage (120vdc or 240vdc) makes servicing much safer
compared to commercial UPS internal DC voltages over 400VDC
because it is cheaper.

9. BATTERY TYPES
• 10 Year Valve Regulated Lead Acid (VRLA)
• 20 Year Valve Regulated Lead Acid (VRLA)
• 20 Year Wet Cell – aka Flooded Cells
• 25-30 Year Life Cycle Nickel Cadmium or NiCad

10. Capital Expense
Factors
(Industrial)
•(1) UPS - Lasts 20-30
Years
•(1) 20-30yr NiCad Battery
Capital Expense
Factors
(Commercial)
• (1) UPS Lasts 7 Years
• (1) 10yr VRLA Battery
Lasts 5 Years
 (To get 10yrs from a
commercial UPS a major
parts replacement must be
performed in the field. The
cost of this replacement
typically equals
replacement cost)
