Do You Have an Obsolete PLC System?

Are you looking for the most cost effective and efficient way to upgrade?

Allen Bradley PLC2

Upgrading your Programmable Logic Controllers (PLCs) to a modern system can be overwhelming and expensive.  There are so many steps to take into account, and no transition is without its unforseen complications.  Whom do you trust to give you reliable informatio and ensure you have the least amount of down-time possible?  What system is right for you?  Are there options that would improve production and prove cost-effective in the long term, or are these bells and whistles just icing that would be wasted expenses in the long run?

Are you up to date on what systems are being discontinued by automation manufacturers?  Allen Bradley routinely posts life-cycle updates for their products, but finding out which one you have and what it's life-cycle status is can be confusing and difficult unless you know exactly what you are looking for.

We at RHZ have the experience you need  - commissioning new systems, upgrading existing PLCs for added sources or changed production practices; maintenance and custom programming to improve performance; optimization of existing programs to simplify operation or address known bugs; upgrades of complete PLC systems to modern hardware including turn-key programming solutions for your whole system, custom built for your needs.

Programming Update: Custom PLC-Based Notification Software

RHZ Environmental can now write custom software that send  out emails and text message the moment a problem occurs. Many RHZ employees receive immediate notifications if a piece of equipment we service has a problem, and daily status notifications of equipment we service on a regular basis. This gives RHZ the ability respond to issue with lightning fast speed.

Trio of Good News: Two Engineering Tests and a rebuild

This chamber was rebuilt and relinedTwo successful Engineering Tests and a Beautiful Relining: The first site had failed its previous EPA test, with an outlet concentration exceeding 6,000PPM. RHZ helped with engineering and controls modifications. The subsequent test found the average outlet VOC concentration dropped from over 6,000PPM to just over 1PPM. We also lowered the combustion chamber temperature by over 50F, which will save them over $7,000/year.  

RHZ also wrote a specialized routine which averaged the chamber temperature for each test.  Due to RHZ's skill at PID tuning, the average chamber temperature was within 0.3F of the PID's set point temperature.  The 2nd site had its engineering test yesterday. We prepped this 20 year old unit for the test a few weeks ago. It achieved a 99.97% destruction rate efficiency. This confirms RHZ's ability to achieve exceptional test results from equipment that has been in the field for decades.  The third site had falling insulation. The walls of the combustion chamber had been ravaged by years of neglect, and an entire section had to be rebuilt. This delayed our total scope of work by only Two Days.
