Caterpillar: Synonymous with Quality and Dependability in Generator Manufacturing

With a longstanding reputation, Caterpillar stands as a beacon of trustworthiness in the generator industry. Globally recognised for their exceptional heavy-duty machinery, equipment, and generators, Caterpillar promises a legacy of unwavering reliability and superior customer service.

Their commercial generator line is engineered to offer thousands of hours of seamless operation before any maintenance is required, establishing them as a prudent choice for consumers seeking small to large-scale generators.

Caterpillar's expansive product range encompasses small and large generator sets, with capacities ranging from a modest 7 kW to an impressive 16,200 kW, providing them a competitive edge in the industry.

Additionally, the ease of specification and purchase further bolsters their market standing. Caterpillar addresses the rising concern over fuel costs with their industry-leading fuel efficiency, ensuring cost savings on refuelling expenses.

Caterpillar's generator sets are designed with customisation in mind, offering a plethora of optional add-ons. If you're seeking a robust backup power generator with integrated solutions for your business, Caterpillar is your go-to choice.

Their generators aren't just world-class; they come paired with high-quality components like batteries, fuel tank bases, security cases, air cleaners, electronic governors, and much more, all aimed at boosting your generator's efficiency.

Backed by a solid track record, an extensive satisfied customer base, and dependable service, Caterpillar generators emerge as a compelling choice for your backup power requirements. Caterpillar caters to businesses of all scales - from small enterprises to large corporations - they have a generator tailor-made for your specific needs.

Remember to explore purchase options from companies like Renteca, especially if you are in Perth. This way, you can gain hands-on experience with your chosen Caterpillar generator before you make the purchase.

Inmesol: A rising star in generator manufacturing

Inmesol, an experienced player in the generator industry for the past 28 years, possesses an in-depth understanding of generator canopy requirements. The company utilises a continuous production system, which involves the application of precision machining processes on high-quality steel sheets using computer numerically controlled (CNC) machine tools. This results in the creation of flawless and dimensionally perfect components. These components are then meticulously welded using a robot, providing spot-on precision.

Every component part of an Inmesol canopy is separately painted, including the joining surfaces, to prevent future rusting, much like the process used in the automobile industry. Each piece undergoes a rigorous cleaning process. Post drying, they are moved to a powder coating cabin for the final stages - polymerisation or firing.

Inmesol canopies are designed to minimise the need for external nuts and bolts. Coupled with their rounded edges, this makes them incredibly sturdy, capable of housing generator sets from 6 to 1000 kVA. Thanks to their thoughtful design and the use of rock wool for soundproofing, Inmesol's canopies are recognised as the quietest in the market.

Comparing Caterpillar and Inmesol: Which generator is the better choice?

Ultimately, the choice between Caterpillar and Inmesol generators ultimately boils down to your specific business needs. Both companies offer a wide range of commercial generators with unique features and customisation options.

However, it is worth considering that while Caterpillar has a more established reputation in the market, Inmesol offers innovative technology at competitive prices.

For businesses seeking dependable performance and service, Caterpillar generators are a reliable option. However, those looking for quiet operation and cutting-edge technology may prefer Inmesol generators. Whichever brand you choose, it's essential to consider factors such as fuel efficiency, product range, customisation options, and customer reviews before making a decision.


Both Caterpillar and Inmesol generators are credible options for commercial use. While Caterpillar is a well-established brand with a long-standing reputation for quality and reliability, Inmesol offers innovative technology at competitive prices.

Ultimately, the choice between the two brands depends on your specific business needs and requirements. We recommend thoroughly researching both brands before making a decision to ensure that you choose the best fit for your business. With either option, you can rest assured that your backup power needs are in capable hands.
