Air Cooled Generators For Sale
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.
Industrial Generators For Sale
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.
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 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-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.
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 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.
