Chillin’ in the New Year

As we kick off 2017, tekWorx and our clients have a lot to celebrate. We’ve worked together to implement chilled water optimization solutions that have cut energy usage and amped up cost savings at their facilities. Here are the highlights:

2016: At a glance

Nissan upgraded their cooling efficiency at a critical vehicle assembly plant without manufacturing downtime using tekWorx innovative hydronic design and adaptive Control Engine Optimization® solution. The result: Cut energy costs by 40% with a 2-year payback.

For UNC’s Charlotte campus, Ameresco requested our hydronic expertise and an adaptive Control Engine Optimization CEO® system that exceed the original kW/ton reduction targets. The result: Cut cooling costs by 30% under performance contract.

Year in and year out, you can count on Approachable Expertise® from our team of highly skilled engineers who will design, install and support your unique chiller plant solution.

New year, new products

Cut out handwritten log sheets and get the technology that self-diagnoses any problems for you.

Our clients can expect 2017 to bring them even stronger results with our new chiller optimization technology tools and resources. First up, ChillerCheck®  ̶  our smart, efficient and fast way to root out refrigerant leaks or fouled coils and tubes that turn into major energy hogs:

  • Collects and analyzes key chiller parameters
  • Determines if the chiller is operating within specs
  • Provides real-time alerts and suggests corrective action
  • Calculates the inefficiencies’ cost impact

Did you know? Chillers can lose up to 30% efficiency and still appear to operate adequately.

We hope 2017 is a fantastic year for our clients and we look forward to creating efficiencies for our current and new customers alike. Contact us ith your next project request and follow us on Facebook, Twitter and LinkedIn for the most up-to-date news and events.

 

COACH™: Integrated Chiller Control and Optimization In One

COACH Logo

tekWorx recently announced the successful completion of multiple installations of COACH™, an integrated chiller plant control and energy optimization system scalable to plants with as few as two chillers.

Using tekWorx CEO® adaptive control technology to control chillers, pumps, and towers, the COACH ™ continuously optimizes total plant kW per ton. The field-configurable package includes a 17” touchscreen and BMS/web gateway in a NEMA 12 enclosure.

“Traditional optimization systems require a BAS to execute the control function, and the combined cost and complexity is simply impractical for smaller and mid-sized plants,” said Mike Flaherty, tekWorx GM. “Integrating the control and optimization functions not only reduces implementation cost but allows our typical 20 to 50 percent saving rage to be realized in these smaller facilities. ”

Built on an industrial-grade PLC platform, the COACH™ uses adaptive control algorithms to maximize plant efficiency in real-time with no ongoing manual tweaking. Fully interactive HMI screens, data logging, trending and alarm handling ensure the COACH™ is both user-friendly and metric-driven.

Retrofitting the Better Buildings Challenge

In 2011 the Obama administration initiated the Better Buildings Challenge, a directive to reduce commercial energy consumption by 20% and to nationally reduce energy by $40 billion by 2020. Unfortunately, finding such savings can be incredibly difficult for buildings when energy hogs remain hidden in faulty lighting, AC, thermostats, furnaces, switches, and fans that malfunction or are altered by human activity. The Better Buildings Challenge has propelled itself back into the spotlight with the recent opening of Seattle’s Bullitt Center in April of 2013. Designed to be 83% more efficient than is typical for a building its size, the Bullitt Center is (self) described as the world’s greenest building. The building works to restore the “natural environment” via solar panels, occupancy sensors, energy emissions, and natural lighting. Regrettably, this architectural marvel does little to provide a roadmap for the energy personnel at existing structures.

Luckily, tekWorx has a successful solution for retrofitting existing facilities. Although an often overlooked area, significant savings are tied to analysis of the chiller plant operations. With at least 30% of all energy costs derived from a building’s cooling system, utilizing tekWorx’s adaptive CEO® system allows facilities to cut their central energy plant costs by as much as 50%. As an added bonus, tekWorx uses a plant’s existing equipment and BMS systems generally eliminating the need for additional capital investments.

tekWorx’s Clients Optimize November Sales

Chrysler and GM Nov Sales

The end of November officially marks the end of any retailing slump as Black Friday and continuous holiday sales kick into full gear. This November was particularly profitable for the automotive manufacturing segment, with the majority of automakers reporting positive results across the majority of available models. Two tekWorx clients, Chrysler and General Motors, lead thelist. The Chrysler Group’s November new vehicle sales were up 16%, making this the best November since 2007 and the 44thconsecutive month of sales gains. Similarly, General Motors reported a sales jump of 14% in November, making this the highest performing year of the last six. These record setting numbers can be partially attributed to an increased focus on the energy component of production.

In the past, automotive manufacturers were inherently pushing their plants to the limit for the sake of production goals, while energy efficiency was given much less consideration. tekWorx optimized the central plants for both GM and Chrysler that feed everything from the headquarters, to paint, engine, and assembly shops. tekWorx efforts not only significantly reduced consumption, but afforded six figured energy rebates. Encompassing millions of square feet of production space and producing millions of ton hours, even small energy savings can make an enormous financial impact in the industrial application.
