Triad Automation was one of the five original business units created by Purvis in 2007.  Triad’s primary focus is to provide automation and controls expertise to all of Purvis’ branches, account managers, and customers.  


Triad’s extensive knowledge and a large stock of drives and controls provide significant value to our customers. We maintain a steady supply of up to drives (up to 700 Hp) and soft starters (up to 500Hp) in multiple warehouses throughout the company to ensure speedy delivery. Need a motor and motor control? We probably have it in stock!


Triad’s regional application engineers are stationed in key locations throughout the company. These knowledgeable field specialists are available to help you troubleshoot your controls problem and help design solutions. Additionally, our in-house support engineers act as the first line of defense when problems occur.

We also offer custom motor control panels through our  ACES - the Automated Custom Enclosure System. ACES was developed in-house by our engineers and allow us to design a motor control panel for virtually any application. Our competitors may take a week or more to provide a proposal, but ACES allows Triad to return proposals quickly and accurately.


Triad offers the rebuild and repair of electronics through our partner, Power Control Services (PCS). PCS offers unmatched warranty and quality with their cleaning process and the use of military-grade components! Contact your Purvis Account Manager today to learn more.

Electric drives may be called many things, such as variable speed drives (VSD), variable frequency drives (VFD), or adjustable speed drives (ASD), but all refer to the same thing. Typically, we refer to them simply as a “drive” or “VFD”. Drives allow you to control the speed of your electric motor.  In many applications, reducing the speed of the motor can result in significant energy savings. This type of application involves a variable torque load and is one of the most common drive applications.


Purvis is proud to represent the world leader in electric motor control as our primary driveline: ABB! The ABB ACS550 is one of the most successful general-purpose drives ever produced, with an installed base of over five MILLION units! For high-performance applications, the ACS880 continues to dominate, continuing the strong legacy of its predecessors, the ACS600 and ACS800. These drives utilize ABB’s proprietary Direct Torque Control (DTC) technology. DTC is the most powerful open-loop motor control method in the world! ABB continues to be an innovator in the drive marketplace and recently released both the ACS580 and the DCS880.


Purvis is also very proud of our Authorized Value Provider status with ABB, indicating our superior knowledge of drives, training, and large inventory. Many of our engineers and account managers are trained in ABB drive applications. Most of our regional application engineers are also factory-trained warranty technicians, meaning they know as much as the ABB service technicians.

The heart of any production line is the prime mover - the electric motor.  Electric motors range from very small and simple direct current motors (aka dc motors) to large, powerful alternating current (aka ac motors) traction motors. Electric motor applications are universal and nearly all industrial processes require electric motors.


Purvis stocks electric motors in multiple variants, such as standard duty, explosion-proof, inverter duty, and crusher duty – all from high-quality manufacturers. We also sell both rolled steel and cast-iron motors. Need a C-face or other flange mount motor? We probably have one in stock.

Our common industrial controls stock includes motor starters, pushbuttons, switches, and control power transformers. Additionally, we stock thermal solutions, such as air conditioning and filter fans. We are happy to provide safety controls, like conveyor pull cords, trap lock switches, and safety mats.


Our network of integrator partners around the country means we can provide custom control systems for almost any application. We work with you to provide solutions, backed by our local integrators, using components from local branches, to provide you with the best options for support and long-term success of your controls systems.
