Four Benefits of Indoor Generators

Indoor generators are always installed in generator rooms that comply with building regulations.

Assembling these generator rooms is the basic process for establishing high-performance commercial indoor generators. Once equipped, these generators have a series of unique advantages that are highly suitable for industrial applications.

1. Controlled climate

Indoor generators are protected from severe weather conditions such as rain, snow, ice, and thunderstorms. Due to life safety regulations requiring generators to supply power to building loads within 10 seconds, they must be kept within the designated operating temperature range. In an uncontrolled climate, generators will not be able to achieve this.

This environmental protection also extends to other common environmental wear and tear of outdoor installation devices, such as:

Overheating: Even outdoor devices equipped with appropriate generator enclosures can face temperature issues in hot weather, lacking sufficient air circulation to cool components.

Leaves: Leaves and other plants must be systematically removed from the casing of outdoor generators, while indoor generators do not come into contact with any brushes.

Ice: All outdoor generators require the construction of ice dams to ensure that ice crystals and bodies do not enter the internal components of the generator and cause lasting damage. The indoor generator is protected and will not come into contact with ice and snow.

2. Security

Indoor generators are not affected by the environment and are isolated from any external interference.

Enhanced system security is particularly attractive for data centers, telecommunications, and medical facilities. The first two industries require smooth, unrestricted 24/7/365 operations to maintain compliance, while the latter cannot use medical devices to perform life-saving functions without power.

However, considering the location of indoor generators within the facility and the proximity of subsequent occupants, indoor generators must comply with a more stringent set of generator room design requirements. However, it is precisely these requirements that enhance their security:

Accessible transfer switches and panels: used for correct load start-up, power-off, distribution, and load adjustment control.

Sprinkler fire extinguishing system: in case of fire or high temperature emergency.

Two hour fire rating: A fire compartment classification system means that a room is designed to accommodate and withstand a fire lasting up to two hours.

More frequent maintenance checks and testing: Some indoor systems require four maintenance checks per year to check levels, load groups, batteries, filters, etc.

3. Noise reduction

Indoor generators can adopt more noise control solutions. Installation can use current building structures and materials to reduce the inherent noise and vibration of any type of generator. Diesel engines or natural gas can be used as backup or primary.

The best noise reduction strategy for indoor generators is an indoor sound attenuation system, which means that the generator room design has an overall sound mitigation function:

Room location: The best practice is to build the generator room in a less frequently used area or on the periphery of the facility.

Generator location: Contemporary sound attenuation can help determine the accurate position of the generator, strategically locate the sound radius of the equipment, and minimize remote noise pollution as much as possible.

Exhaust muffler and muffler: In addition to the diesel engine and radiator fan, the noise generated by the generator exhaust is the highest. The built-in muffler and silencer in the system can greatly reduce exhaust noise interference.

4. Exhaust gas control

Waste gas cannot be mixed with the HVAC intake system of facilities or buildings. Although this is a risk for all types of generators, outdoor units cannot configure fully customized compliant spacing between the generator exhaust control device and the HVAC air inlet like indoor generators.

Additional architectural attention to indoor generator rooms can help alleviate the problem of exhaust gas infiltration. The internal generator room is designed with isolated exhaust pipes and absorption filters. Without significant facility upgrades, outdoor units cannot easily adopt these designed systems.
