Process Cooling Magazine is sponsoring a Free Webinar Entitled "Cooling Tower Water Problems & Solutions" on April 13, 2011.   Our partner, CoolingTowerChemicals.com is a sponsor of this event.

From the Organizers:

Cooling tower operators pay careful attention to their system's water because water quality problems negatively impact their process, product and bottom line. Water expert Paul Puckorius gives you the benefit of his more than 50 years of experience with advice on tackling and solving an array of real-life tower-water problems. And then you get to ask him your own questions.  You'll learn about:  Correcting water chemistry to protect old and new galvanized steel towers – mechanically or chemically. Handling high dust and corrosion with filtration. Addresses both heavy and light particulates. Using recycled water. Solving microbiological corrosion with improved biocides and monitoring. Using new solid-based products to eliminate handling, shipping and storage of liquid treatments. Saving chemicals and protecting equipment with coatings and sacrificial anodes in water boxes and tube sheets. Cleaning up and preventing film-fill fouling. Monitoring and automation of water quality for protecting equipment and reducing manpower. Controlling deposits with inhibitors that eliminate acid. Conserving water with new deposit and corrosion inhibitors.

Corrosion-free Delta Cooling Towers have many advantages over standard galvanized towers:

• Can Not Rust
• 15 Year Shell Warranty
• Minimize Downtime with Direct Drive Fans
• Lowest Cost of Ownership
• Not Harmed By Water Treatment Chemicals

To take advantage of this offer, which expires 2/28/10, you will need to provide before and after photos of your installation.  To take advantage of this offer, please contact Robson Industries Inc. for a no obligation quotation for the tower that will meet your needs.

An online resource for professionals in the heat treating industry, Heat Treating Forum, continues to grow.  Users find discussions about Processes (Brazing, Carburizing/Carbonitriding, Induction...), Equipment (Atmosphere, Induction, Vacuum...), and general industry news.  

We wish this group the best as they continue to grow their online commmunity.

The Robson Industries Inc. Single Cartridge Filter Skid has been designed to be easy to install and use. It simply plugs in to a standard power outlet, and because of its low profile casters, can roll with a machine sump on wheels. The cartridge is located low to the ground, and swing bolts with eye nuts make filter changes simple and quick. The powerful 1 HP self priming cast iron pump is designed to optimize use of the cartridge for less frequent changes.

Speaking of cartridges, this Single Cartridge Filter Skid uses readily available cartridges, not expensive proprietary cartridges. You can purchase media from us, or any number of vendors including McMaster-Carr Supply Company, who stocks them nationwide.

We have partnered with Google to manage the online purchasing of these packages right from our website.

Robson Industries Inc. kicks off Westec 2009 by displaying a DUP-3-90 Duplex Cartridge Filter Skid at the Los Angeles Convention Center this week.  This skid has been designed for ease of use and has been met with favorable reviews by plant engineers who have noted the small footprint (only 40" x 28") and easy serviceability.  Purchasing managers appreciate multiple sourcing for the filter media, as they are not locked into a "special" filter size.  

We hope to see you there!

SHOW HOURS

This photo shows two heat transfer plates from a Plate & Frame Heat Exchanger.  The one on the left was from a system with no water treatment whatsoever.  Minerals in the cooling tower water built up and fouled this plate in only three years!

This slowly reduced the performance of his equipment as the cooling water was unable to flow through the heat exchanger.  As heat transfer became almost non-existent, our customer risked damage to his equipment due to excessive temperatures.

The good news is that this sort of damage is avoidable and management of process and tower water is easy to do and will pay for itself in improved long term performance and reduced energy usage.

Evaporative Cooling Towers blow air over water to evaporate it, allowing for water temperatures below even the ambient temperature.  This process leaves minerals behind, so a simple bleed (running some of the water to the drain regularly) will keep this in check.  More sophisticated diagnostic methods are available, including monitoring conductivity of the water to determine the mineral levels.  For cooling tower water, an algaecide may also be required.

Robson Industries Inc. provides clear instructions for proper treatment of its systems, and our water treatment expert will work with you to set up a schedule of maintenance to keep things running smoothly.  

With a little bit of planning, damage like this can be easily avoided.  Please contact Robson Industries Inc. if you have any questions about water treatment for your Process Water Cooling System.

Operating the electric motors that comprise a Process Water Cooling System generally make up the majority of ongoing operation costs.  All motors have efficiency ratings, which are a measure of how efficiently the motor can convert electrical energy into rotational power.  

Motor manufacturers produce motors rated as standard efficiency, high efficiency, and premium efficiency.  Premium efficiency is an important designation from NEMA that specifies performance criteria that must be met.  Many of our customers specify Premium Efficiency motors for their operations, and their adoption is only increasing as energy costs are more closely scrutinized.

High Efficiency is a term that refers to motors that more than meet the minimum efficiencies from the standard motors.  With this designation, you achieve most of the energy savings of the Premium Efficiency motors at a lower cost.  

Variable Speed Drives also act to make a motor more efficient, because they allow a pump to run at the exact speed required for the process.  

High Efficiency pump motors are standard on all Robson Industries Inc. Process Water Cooling Systems.  Premium Efficiency motors are available as an upgrade to any system, and our Green Drive Package (available with any system) includes an upgrade to Premium Efficiency motors along with the integration of Variable Speed Drives for the most cost-efficient operation possible.  This, combined with proper pump selection and system control, will give you the best results for the lowest overall cost.

Source: Motor Efficiency (http://www.psnh.com/Business/SmallBusiness/Motor.asp) by Public Service of New Hampshire - Electric motors consume 64 percent of the electricity produced in this country. Although they are generally efficient, motors are often run at lowered efficiency because the motor size is not matched to the horsepower requirements of the task.

This unit featured two large diameter fans, designed to rotate at a relatively low speed for longer life and reduced noise.  The drive assembly is shown here during construction and as a finished product.

This massive unit measured over 30 feet long, 12 feet wide, and weighed over 33,000 pounds.  Watch the video below to see how we moved the unit out of our facility and onto its delivery truck.  Yes, the door is 12 feet wide.
