You have probably heard the brand name Hitachi in all kinds of contexts that don’t have anything to do with commercial compressors. Hitachi is one of the most successful companies in Japan and it has been around for more than 100 years. In that time, it has done a little bit of everything.
In fact, there are nine major product divisions within the Hitachi enterprise.
With expertise in automotive systems, construction machinery, defense, digital media, telecom, electronic equipment, power systems, and many more, you might wonder whether Hitachi has the specialized insights necessary to deliver a truly great commercial compressor.
As it turns out, the company’s diverse skills help it integrate lessons from many different fields.
Hitachi Stands Out for Its Oil-Flooded Rotary (Screw) Compressors
Hitachi’s compressors are offered under the banner of the Hitachi Industrial Parts company. It has a variety of systems including refrigeration and HVAC/R compressors, as well as a line of air compressors, that Compressors Unlimited does not sell. It also has one of the longest histories when it comes to large-scale centrifugal compressors.
It claims to have supplied more than 1,300 of these units all around the world.
With compressors large and small to choose from, it may be tough to know where to start navigating the Hitachi catalog. But if there is one type of Hitachi commercial compressor that our customers come back to again and again, it is the oil-flooded rotary (screw) compressor.
For most projects, screw compressors are a marked upgrade from reciprocating compressors in virtually every way. Superior lubrication and an overall reduction in points of fault make these highly reliable. They don’t suffer from the wear and tear that’s so difficult to mitigate with piston-style compressors.
A screw compressor uses rotary displacement, significantly reducing friction for the entire compression process. Oil-flooded screw compressors employ lubricated seals within the chambers. The presence of oil creates a powerful dividing element between the chambers and improves overall performance.
In these units, opposing threaded screws do the work of compressing the refrigerant gas. Air travels through the unit as the screws spin, enabling the gas to reach the required pressure and ultimately become available to the rest of the system. The entire process is highly mechanically efficient.
How Hitachi Rotary Compressors Excel
Naturally, every compressor company has its own strengths that it brings to the market.
Let’s take a closer look at precisely how Hitachi compressors outperform their rivals:
1. Energy Efficiency
All around the world, Hitachi is one of the leaders of the pack when it comes to compressor energy efficiency. No matter which Hitachi model you purchase, you can expect it to compare favorably with others in terms of energy use. This reduces cost of ownership as well as your carbon footprint.
You might wonder whether a Japanese company will meet all of the applicable EPA standards for your commercial compressor, but worry not. In many cases, Hitachi compressors go above and beyond the current environmental regulations. That helps you to future-proof your operations.
2. Long History of Innovation in Rotary Compressors
Hitachi has one of the longest histories with the rotary compressor. Its multi-speed rotary compressors hit the market back in 1993 and have undergone a variety of upgrades and updates ever since. This is a remarkable brand when it comes to delivering more power and performance in a compact footprint.
3. Easier Maintenance than Many Competing Compressors
Modern commercial compressors add much of their value by being more serviceable than the models of the past. The easier it is to diagnose, maintain, and repair a compressor, the more money it can save you in the long run because it is more likely to perform well for its entire service life.
Hitachi screw compressors have been designed from the ground up with easy maintenance in mind. As long as you have the compressor spare parts you need, it is very easy to keep your Hitachi rotating compressor in good working order. That can give you real peace of mind.
Improve on Hitachi’s Value with a Remanufactured Commercial Compressor
When browsing Hitachi commercial compressors, you’ll find them available in models ranging from 7.5 to 240 KW. They incorporate variable speed options and are diverse enough to suit nearly any operating environment or application. All in all, Hitachi is always a strong selection.
By choosing a remanufactured commercial compressor, you can enhance your value even further.
A remanufactured commercial compressor undergoes a thorough quality control process overseen by experienced compressor engineers. The unit is completely disassembled and cleaned. Components all throughout the system are updated and replaced as necessary and testing occurs throughout.
With remanufacturing, you may save hundreds or even thousands of dollars on your Hitachi compressor as well as weeks off the time it takes to source and ship. Harnessing the power of Hitachi has never been easier.
