Zentel Tech Optimizes Rare Book Storage HVAC

Zentel Tech was contacted by the director of commissioning for a world renown institution to investigate issues with the HVAC in their rare book storage. Zentel Tech reviewed all of the information and equipment. The initial complaint was that the heat was being carried over to the supply air from the desiccant regeneration system causing the temperature to rise in the rare book storage. A secondary issue was the motor for the desiccant wheel failed due to the motor leads overheating.

Quad Plus Adds Seven New Synchronous Motor Field Application Systems at The Chicago Water Departments South Water Purification Plant

Quad Plus has completed their installation portion of the 45 million dollar Electrical Distribution revamp of The City of Chicago’s South Water Purification Plant. This first phase of the project was to install 9 new PCP’s (Pump Control Panels), for 7 synchronous and 2 induction motors. These panels completely changed how the motors were started from the existing systems installed in the late 1940’s. The installation team consisted of MG Electric (general contractor), Quad Plus (provided 7 Synchronous Motor Field Applications Systems), Siemens Industry, Inc. Switchgear Division (supplied new Switchgear and motor starters), and Allen ICS (Supplied SCADA equipment and programming). One of the challenges was that the Plant could not be shut down to accomplish this retrofit.

Ask Al presented by Quad Plus - Siemens Masterdrive Servicing

I have received many notifications about the discontinuation of the Siemens Masterdrive. As an owner of this drive system, this is the type of communication that causes anxiety. Questions such as How am I going to get parts, repairs, and service immediately start swirling in your head. And the biggest question of all is, if I have to remove and replace these drives, how much will it cost, how long will it take, and are their implications to my automation system.

So, what exactly does this notice mean?

How long should your fan run for?

We all know we shouldn’t wait until our cooling fans come to a complete stop before replacing them on our Motor Drive/Power supply units. By not having the proper cooling ventilation on our equipment it can cause overheating causing electronic devices to malfunction or fail resulting in severe damage to the Drive/Power Unit. .

So...what are some of the steps to prevent these types of failures

Ask Al presented by Quad Plus - Reforming Capacitors

Many AC Drives and other inverter types (i.e. solar) contain aluminum electrolytic capacitors for DC bus filtering. If these capacitors have been in storage for a period of time, for example in your spares, they may explode if reforming is not performed BEFORE applying full power. In this video we explain what is going on in the capacitor and what you can do to prevent explosions.

CAD Department Development - Getting Started

When a project reaches our CAD Department desks, we, the CAD team, start developing the schematic and Mechanical drawing sets. Let’s not forget, however, that back in the day - which is around the year 2014 and before, we could only develop the schematic part of the project drawings. Upon completion, we submitted the drawing set to the shop to use in developing the Back-Panel layout.

Today, we are easily able to develop all drawings needed for any of the company’s projects ?  Ambition, commitment, & determination of the CAD team, along with Quad Plus Management’s support & guidance, brought our CAD work great success during the time of development.

Don't Start No Static!

Electro-static discharge (ESD) can be a serious problem when handling electronic equipment. It can cause permanent damage in both an immediate and latent fashion causing components to fail prematurely. The little electric arc we produce when touching a door knob is somewhere between 2,000 and can be as much as 35,000 volts!
