Advantages of Buying Overstock/Refurbished Industrial Equipment

The choices when you buy industrial automation equipment are varied.  Do you buy new? Overstock? Refurbished? Do you consider repairing your current part?  Some of these decisions will be predicated by the age of your factory automation systems and the availability of parts.  Older, legacy systems that are no longer supported by the OEM give limited options and may offer a challenge when sourcing quality replacement parts. 

Here at AX Control, we stock a wide range of professionally refurbished, repaired, and reconditioned automation parts from companies like GE, Eurotherm, and Reliance Electric, just to name a few.  Every piece of legacy equipment we sell has been inspected, cleaned, tested, serviced, and brought up to proper working order before we place it into our available online inventory. When you order from us, we carefully pack each product so it will reach you in the exact condition it was in when it leaves our facility and is guaranteed to arrive not DOA. 

Overstock/Refurbished: definitions.

Overstock parts exceeded the original demand from the OEM. Many of these parts have never been used and remain in their factory packaging.

Refurbished parts, on the other hand, have been used. They make their way to us in a number of ways, but regardless of how they get here, they are fully checked over and optimized before we place them in our inventory. While these parts may show wear associated with age and use, they are in good working order and are fully reliable.

Reduce(your costs.) Reuse. Recycle.

Other advantages to buying refurbished parts from AX Control include: 

  • Reliability–Since we take such care in preparing our automation parts for sale, you can be confident in their durability.  Additionally, all items are automatically warrantied upon purchase. You can learn more about the warranty terms for a specific product on that product’s individual page. 
Five stars to show quality.  Industrial Automation Equipment is built to last.
  • PriceRefurbished legacy parts at AX Control are typically sold at a fraction of their new cost.   This significant cost savings allows our customers to maintain an inventory of on-the-shelf spares without a lot of outlay of capital.  These available spares, in turn, minimize downtime for your facility. No one wants expensive downtime.
  • Equivalence–OEM parts can swap out like-for-like. This is an easy way to avoid compatibility issues that can occur with upgrades to your existing equipment.  This also avoids the functionality and fit issues that sometimes occur with third-party parts. The cost in time is important here. Issues may not be obvious until a part has been delivered and fails to work on your system.

The Reliance VFD: Basics of Variable-Frequency Drives

Reliance VFD drives have been around for years. VFDs have been widely used for industrial applications, for good reason. Pulse-width modulation (PWM) VFDs offer low costs, high efficiency, and excellent input power factor.

However, VFDs need proper care and installation to run optimally. Sometimes this means controlling airflow going to the drive to control heat generation. VFDs have a typical efficiency rating between 95-98%. But VFDs produce more heat than other electrical equipment, especially when enclosed. And heat losses are directly related to the VFD’s efficiency rating.

Make sure to note your drive’s max operating temperature under real operating conditions. Some drives can operate to 122 degrees Fahrenheit safely. Others can only withstand max temps of 104 degrees Fahrenheit before overheating. To extend the life of your equipment, err on the side of caution and try to operate VFDs below their rated max operating temperature. This will extend your equipment’s lifespan. It will also reduce any risk of localized overheating.

Positioning is Key

One way to ensure your Reliance VFD maintains temperature is through proper positioning. Try to place VFDs close to the bottom of electrical enclosures. This will ensure incoming air is as cool as possible, since it hasn’t already run across other components. Also, maintain recommended right-to-left clearances between units.

Why Are VFDs Used?

Many prefer VFDs like the Reliance VFD over single-speed drives because they can control the speed of an AC motor while offering smooth startup capabilities. Adjustments to frequency delivered to the motor prevents straining from heavy load.

VFD Design Saves Energy

This same frequency adjustment offers energy savings, too. VFDs allow motors to operate at less than full speed. A 25% reduction of motor speed can decrease energy consumption by close to 60%. Meanwhile, a 50% reduction can decrease consumption by almost 90%.

It is important to note “frequency adjustment” can also fall under the misnomer of “speed control.” Speed control is the result of the former. As downward adjustments in frequency occur, other improvements follow improved energy consumption. Mechanical stress lowers, extending machine lifetime. Noise levels also reduce.

Where are VFDs Used?

Three out of every four VFDs produced end up as part of control systems for pumps, fans, and compressors. It is easier to control the speed of a pump through a VFD rather than try to control the flow of water or air in the system through valves. This makes VFDs perfect for pump and fan applications.
