In general benefits of Hitec Power Protection diesel rotary UPS systems are:

• The most reliable UPS system
• The most cost efficient system
• The most environmental friendly system
• The most space efficient system

Hitec Power Protection’s unique concept for assuring uninterruptible, continuous and conditioned power rests on four basic principles. Each of them contributes to the unprecedented advantages of our diesel rotary UPS system (DRUPS) over traditional static UPS systems using batteries.

The four basic principles are: 

 1. Hitec DRUPS = Static UPS + standby generator
 2. Hitec DRUPS = Line-interactive system
 3. Hitec DRUPS = Active filter
 4. Hitec DRUPS = Battery-free solution 

1. Hitec DRUPS system = static UPS + standby generator

Our diesel rotary UPS system is based on a simple and reliable concept. It replaces a static UPS, providing temporary power via its batteries, and a standby generator, providing power for longer outages, with only one system.

Your benefits are:

• Fewer components, meaning higher reliability (MTBF) and lower installation costs
• Smaller footprint: saving 40 to 60% in space
• Higher energy efficiency: no power conversion and no conditioned battery room are required
• No environmental unfriendly batteries are required

2. Hitec DRUPS system = line-interactive system

Hitec Power Protection DRUPS systems are line-interactive and run in parallel with the utility power.

Your benefits are:

• Optimal use of utility supply
• Continuous lifeguard for critical applications
• No conversion of electrical energy flowing from utility to the critical load, meaning high end-to-end energy efficiency

3. Hitec DRUPS system = Active filter

The combination of the reactor (choke) and synchronous alternator in the Hitec DRUPS system acts as a filter to clean the incoming utility supply.

Your benefits are:

• Filter for all utility born power quality problems
• No use of power electronics to generate, condition or convert the output voltage, meaning no production of harmonics
• Harmonic filter to both supply and load borne harmonics
• The generator supplies the reactive power drawn by the load, resulting in utility power factor being always close to unity.
• Compensation of utility voltage deviation

4. Hitec DRUPS system = battery-free solution

The Hitec Power Protection DRUPS System uses stored kinetic energy to bridge the diesel engine start time when there is a utility power failure. It is a battery-free concept, which was invented and patented by Hitec Power Protection in 1969.

Your benefits are:

• Proven, environmental friendly UPS concept
• No conditioned battery room required
• No battery replacements after 3 to 5 years, meaning no chemical waste
• The more UPS power you need, the more our concept is the winning concept. Power means batteries to be installed, resulting in investments in space for larger battery rooms.
