Have I mentioned before we have an amazing machine shop at DEMCO?!?? We had a customer call us late on Thursday with a breakdown. They snapped a mixer shaft on a critical piece of equipment in their process. Our machinists worked a lot of overtime to get this completed and delivered early Saturday.

Today’s project was a Toshiba S15 installation in a mobile HVAC unit. This unit was using a competitors drive that failed. This is not something the end user ever wants to happen, especially when they are already renting this unit and without air conditioning in their building. I ended up replacing 2 of them and saving the program with ASD Pro so the customer can easily replace more units in the near future.

Another cooling tower upgrade completed at a power plant in Delaware. We removed a magnetic coupling that was inline with the motor and fan and added a longer carbon fiber driveshaft. To control the towers cooling temperature we added a Toshiba AS3 (pictured). This is the second cooling tower upgrade we did at this plant in the past year.

We have been working on a project for the last week with one of our power plant customers. They had an old MagnaDrive and Beck drive controlling the speed of their cooling fan. It was way past its service life and was causing them a lot of vibrations and they were really worried about reliability.

We removed all of that and installed a longer Rexnord Carbon Fiber driveshaft to connect the motor to the gearbox. Also, we removed and installed another gearbox that we had rebuilt a few months ago. In addition, we reconditioned their existing motor and installed shaft ground rings in the motor to prevent bearing fluting.

To top this off, we installed a Toshiba AS3 VFD to control the fan speed and provide feedback to their control room.

Great project that displayed a lot of our capabilities.

Another successful Toshiba AS3 VFD install today for a customer that had a submersible well with over 1800ft of motor leads. Several of our competitors drives couldn’t get the job done but we made it happen. Thanks to some support from Toshiba on this one, as it had some interesting issues that came with it.

Completed an installation of a Toshiba AS3 VFD for one of our customers. They recently just switched to Toshiba after using one of our competitors for several years. What made them switch? 1. Toshiba has a very good inventory even with the supply chain issues others manufacturers are experiencing. 2. Very price competitive among other top brands. 3. Superior product support. We don’t just sell VFD’s, we install them and give the customer 24hr local support if they have any problems.
