Robust, compact, proven technology

• Life expectancy of a Hitec rotary UPS is 25 years.
• Except for regular maintainance no re investment costs 
• The amount of floorspace of a Hitec rotary UPS system is half the floorspace required for a static UPS

The energy storage of a Hitec UPS will not reduce over time 

• The energy storage capacity of batteries reduces when they get older. Therefore batteries have to be renewed every 3-6 years,  generating costs for the UPS owner. The old batteries are environmental unfriendly waste.

Power Quality

• The output voltage of a rotary UPS is clean. A static UPS produces distortion on its output voltage
• Hitec Rotary UPS can easily feed capacitive loads while static UPS systems have restricted possibilities to feed capacitive loads.

Hitec UPS offers the highest level of downtime protection

• Unlimited autonomy time at full load.
• Hitec Rotary UPS significantly reduces the risk of damage due to short-circuit because Rotary UPS is able to supply high short-circuit current to activate the load’s protection fuses. Static UPS has limited short circuit capacity.
• The flywheel of a rotary UPS is recharged in 10 minutes. Recharging the batteries of a static UPS requires many hours. During the recharging a static UPS provides only a restricted protection of the load.
• A Rotary UPS can recharge its flywheel (with the diesel engine) when the mains voltage is absent. A static UPS can only recharge after the mains voltage has returned

Hitec Rotary UPS is less critical technology 

• The temperature of the room does not influence Hitec rotary UPS.
• Battery rooms have to be conditioned, which costs extra money.

Simplicity increases MTBF of Hitec rotary UPS

• A Hitec rotary UPS is built with a limited number of parts. Technology that has been improved and used successfully over 30 years. A Static UPS has complicated, vulnerable, power electronics which reduces reliability.
