Air Cooled Generators For Sale

Air Cooled Industrial Generators

Air-cooled industrial generators use fans to dissipate heat, while liquid-cooled generators use coolant to regulate engine temperatures. Air-cooled models are typically more affordable, easier to maintain, and ideal for lighter commercial or industrial applications. However, they tend to run hotter, which can reduce lifespan and limit power output. On the other hand, liquid-cooled generators offer superior cooling, are quieter, and can handle more demanding applications but come with higher upfront costs and more complex maintenance requirements. The choice depends on budget and power needs. An air-cooled generator relies on ambient air to regulate engine temperature. The cooling process can be passive, where the heat naturally transfers from the engine to the surrounding air. As the heated air rises or wind carries it away, fresh air flows in to remove more heat. This passive system is typically sufficient for open-frame or portable generators, providing enough cooling for smaller, less demanding applications. Learn More -->

Air cooled generators are produced in two basic configurations:

- Open ventilated (OV) - In the OV design (Most common), outside air is drawn directly from outside the unit through filters, passes through the generator and is discharged outside the generator. 

- Totally enclosed water to air cooled (TEWAC)- In the TEWAC design, air is circulated within the generator, passing through frame-mounted air to water heat exchangers (like radiator does in a car). In this process, the water is circulating and enters the heat exchanger that cools down the air which directly penetrate the internal part of the generator.

Liquid Cooled Industrial Generators

Liquid-cooled industrial generators use a radiator and coolant system, much like a car, making them more effective at handling high-power loads and running for longer periods compared to air-cooled models. They offer greater durability and quieter operation (which is why they are used for marine engines), ideal for heavy-duty commercial use. However, they have higher upfront costs and require more maintenance due to their complex cooling systems. Liquid-cooled generators generally have a longer lifespan than air-cooled models, as the cooling system prevents the engine from overheating, but regular upkeep of the radiator and coolant is essential for optimal performance.

Natural gas, diesel, and propane liquid-cooled generators offer differing fuel choices for anyone who needs backup power during an outage.

Fuel Types

At Rosco Industrial Supply, we provide a wide range of industrial-grade and residential generators to ensure you’re never left in the dark. Whether it’s for your home, business, or industrial site, our backup generators are designed to deliver reliable power during outages caused by storms, natural disasters, or unexpected grid failures. We offer most major brand manufacturer generators powered by different fuel types, including diesel, natural gas, propane, and gasoline, to suit the specific needs of every customer. Whether you’re preparing for hurricane season or power interruptions, our generators provide peace of mind with dependable power solutions.

When choosing a standby generator, it’s important to consider the pros and cons of each fuel type. Diesel generators offer fuel efficiency and longer run times but require regular fuel maintenance and can be noisier. Natural gas generators are convenient for homes connected to city gas lines and offer clean operation, though they are less portable and may be affected by service disruptions. Propane generators burn cleaner and can be stored for long periods, but they require large storage tanks to access the fuel. Gasoline generators are usually smaller and more affordable and widely available but have shorter run times and require frequent refueling, making them less ideal for long-term power outages. Usually not ideal for larger homes.

Propane Generators For Sale By Generac

Propane Fueled Generators

Propane generators are a great choice for backup power due to their clean-burning fuel and long storage life. The most common choice for residential generators so they're ideal for homes & businesses alike, propane generators are reliable and environmentally friendly. However, there are factors to weigh before choosing one over other fuel types.

Pros:

- Clean-burning with lower emissions
- Fuel can be stored indefinitely without degradation
- Quieter operation compared to diesel generators
- Less maintenance required

Cons:

- Requires large propane storage tanks
- Shorter runtime compared to diesel
- More expensive fuel compared to gasoline and natural gas

Propane generators are excellent for environmentally conscious users but may require more space and higher upfront costs for fuel storage compared to a natural gas options.

Natural Gas
Generators

Natural gas-powered standby generators are a popular choice due to their consistent fuel supply from a home's existing gas line, eliminating the need for fuel storage. They are quiet, low-maintenance, and environmentally friendly with cleaner emissions. However, they can be costly to install if a gas line isn’t already available, and they may not function during gas supply interruptions. Basically very similar to propane, it just comes down to what gas type is more easily accessible for you as the home owner or business. If you live in a neighborhood that's a nat-gas community, then go with this. If you do not, then know you're going to have to get a propane tank buried, or sitting beside or behind your home to fuel the generator.

Gasoline
Generators

For the tailgater in all of us the gasoline-powered standby generators are often chosen for their portability and easy fuel access. Gasoline is readily available and ideal for smaller applications, making these generators a flexible option. However, gasoline is highly flammable, has a shorter shelf life, sometimes loud and requires frequent refueling, making it less suitable for long-term power outages. All major manufacturers of generators sell the gasoline powered generators, so it really just comes down to who has the best customer reviews for reliability, ease of services, and lifespan.

Cummins Diesel Industrial Generators

Diesel Generators

Diesel generators are a popular choice for standby power, especially for industrial or commercial use. Known for their durability and fuel efficiency, diesel generators can handle heavy loads for extended periods. They are often the go-to solution for situations that demand reliable backup power over long durations. However, there are several factors to consider before deciding whether a diesel generator is the right choice.

Pros:

- Long lifespan and durability
- Fuel-efficient, especially under heavy loads
- Low maintenance compared to other types
- Reliable in extreme conditions

Cons:

- Noisy operation
- Higher upfront costs
- Requires proper fuel storage and maintenance
- Emissions concerns in some areas

A diesel generator may be ideal if you need robust, long-lasting power. However, it might not be the best fit for residential use due to noise and fuel handling requirements, where natural gas or propane options could offer quieter, cleaner alternatives.
