850KVA Cummins Diesel Generator Containerized Type For Saudi Arabia | KT38-G

850KVA Cummins diesel generator set 60HZ 400V for the back up power for a local shopping mall in Saudi Arabia.

For large shopping malls, a diesel generator set serves as a silent yet absolutely vital “guardian of power.” While it may go largely unnoticed during normal times, the moment a utility power failure occurs, it must immediately step in to ensure the mall’s continued operation and safety. Its primary functions and significance are manifested in the following key aspects:

🛡️ Core Function: Emergency and Backup Power Supply
Shopping malls are highly populated environments; a power outage here would not only result in massive economic losses but could also trigger safety incidents, such as stampedes. Consequently, the core function of a diesel generator set is to provide timely and reliable power support to critical equipment and areas whenever the main utility supply is interrupted.

This function is broadly categorized into two types:

Lifeline (Fire Safety Loads): This constitutes the absolute priority. In the event of an emergency—such as a fire—the generator set must start immediately to power fire safety equipment, including fire pumps, sprinkler systems, smoke extraction fans, fire elevators, emergency lighting, and evacuation signage. This ensures the safe evacuation of personnel and facilitates initial firefighting efforts.

Operational Lifeline (Critical Loads): Beyond fire safety, the generator set must also safeguard the mall’s basic operations and minimize economic losses. This encompasses systems such as point-of-sale (POS) terminals, low-voltage equipment rooms (for network and communication infrastructure), surveillance centers, at least a portion of passenger elevators, domestic water pumps, and basic lighting in select public areas.

📝 Key Design and Technical Requirements
Effectively deploying a generator set within a shopping mall environment requires a comprehensive assessment of multiple factors. The following are some critical considerations:

Capacity Calculation: The capacity of the generator set cannot be chosen arbitrarily; it requires precise calculation. Typically, separate calculations are performed for “Fire Safety Loads” (the total power demand of all equipment that *must* activate during a fire) and “Critical Operational Loads” (the total power demand of essential equipment that *must* be sustained during a utility outage). The higher of these two values ​​is then selected to determine the generator set’s required capacity, thereby ensuring that power demands can be met under any scenario.

Rapid Startup and Switching: Shopping malls demand a power transition process that is virtually seamless. The generator set must feature a rapid automatic startup capability, typically required to initiate and assume the electrical load within 15 seconds. This functionality relies on the integration of an Automatic Transfer Switch (ATS), which automatically monitors the status of the utility power supply and instantly switches the electrical load to the generator set the moment a utility failure is detected. Installation Location and Environmental Considerations: Given the high cost of real estate, shopping mall generator sets are typically situated in basements or dedicated equipment rooms. This presents a series of challenges that require specialized design solutions:

Noise Reduction: Employing silent-type generator sets or implementing soundproofing measures within the equipment room to prevent noise disturbance to the public.

Ventilation and Heat Dissipation: Designing highly efficient air intake and exhaust ducts to ensure that basement-located units can effectively dissipate heat and operate normally.

Exhaust Management: Prudently designing exhaust piping to channel waste gases to the rooftop—or to locations with minimal public impact—while also ensuring proper thermal insulation of the piping.

Reliability and Maintenance: As “standby” equipment that is rarely in active use, its reliability is of paramount importance. Regular test runs and maintenance are essential to ensure the unit remains in optimal condition, capable of a “one-touch start” and reliable operation during emergencies.

📝 The specification of the 850KVA Cummins diesel generator set

  Prime power (PRP): Prime power is available for an unlimited number of annual hours in available load application, in according with GB/T2820-97(EQVLso8528); A 10% overload capability is available for a period of 1 hour within a 12-hour period of operation.

  Standby power Rating (ESP): The standby power rating is application for supplying emergency power for the duration of a utility power interruption. No overload, utility parallel or negotiated outage operation capability is available at this rating.
