TEC and RenewAire Team Factory Visit

Last month RenewAire hosted TEC customers and employees at their new LEED Gold office and manufacturing facility in Waunakee, WI. Participants were awarded PDH hours during this visit and helpful knowledge to pass on.

It was a two day event that started with a tour and tasting at the Ale Asylum Brewery in Madison, where everyone was delighted with the brew master’s concoctions and a host of tasty hors d’oeuvres. As a special treat everyone was shown the refrigeration side of the brewing process, which was to the delight of the HVAC team!

The next day started bright and early with RenewAire’s VP of Sales and Marketing, Nick Agopian giving a brief history of the company, and how they are represented in the world of IAQ. He stressed the importance of better air quality for the health and well-being of the world population. Up next was Product Manager Nishant Kanapilly; his main focus throughout the first part of his presentation was Federal and State codes and standards, and how they are encouraging everyone to go beyond the requirements for better IAQ. In the second part of the presentation he touched on the importance of zero air cross leakage and how the Energy Recovery Ventilator can affect payback.

This was the perfect time for Technical Support Manager, Dave Baldus to discuss how to utilize RenewAire. He spoke about installation faux pas and maximizing performance. For the participants to fully grasp RenewAire’s products and their performance, a factory tour showcasing the new production facility and LEED Gold HVAC plant took place. One of the highlights was a viewing of their new Dedicated Outdoor Air System that combines an ERV, heating and cooling in one system.

The day finished with Nishant and Nick giving a demonstration of their new CORES software selection tool that distributors, engineers and contractors have at their disposal.

All who attended this visit found it to be an informative and worthwhile day. Participants expressed that their visit will generate new ideas and sales. Future visits will be available.

Tower Tech Reaching New Heights in Chicago

340 On The Park was looking to reduce their rising costs of chilled water from the local utility by installing and operating their own chiller plant on the top floor of the building. They hired consultant Cyclone Energy Group to provide design, cost analysis, feasibility, and energy modeling services. TEC worked closely with Cyclone Energy to provide the owner with several options:

  • Option #1: Carrier Air Cooled Scroll Chillers
  • Option #2: Carrier 19XRV Centrifugal Water Cooled Chillers And Tower Tech Cooling Towers
  • Option #3: Carrier 23XRV Ultra High Efficient Water Cooled Screw Chillers in Series – Counter flow Arrangement and Tower Tech Cooling Towers

The Condo Board selected Option #3 which provides the most efficient design, largest utility rebate, and quickest return on investment. Click here and watch a video of the unique lifting operation.

The unique equipment selected offers unparalleled benefits not found in other conventional chillers and cooling towers.  Here are just some of the unique benefits:

Tower Tech Cooling Towers

  1. Multiple direct drive fan design provides inherent redundancy in the event of a fan failure
  2. 80% less drift heavily reduces water and chemical usage
  3. Pultruded FRP construction of the cooling tower eliminates corrosion and extends tower life
  4. Variable flow nozzles utilize the entire surface area of the media and increase energy efficiency at part load conditions
  5. Unique basin design keeps the water dark and at a high velocity virtually eliminating  the risk of algae and legionella growth
  6. Simple maintenance done from the ground level.  No more ladders and harnesses.

Carrier 23XRV Screw Chillers

  1. Simple design with only 3 moving parts (screws).  No inlet vanes or actuators to fail.
  2. Positive displacement design means no compressor surges.
  3. Rapid adjustment to load changes ensures maximum comfort for the tenants
  4. Series Counter Flow design enhances the efficiency an additional 5-10% over the competition
  5. No compressor teardowns required
  6. 50 year bearing life

Applications, Advantages & Highlights of KN Boilers

Modern boiler applications call for technology that is innovative, flexible and adaptable. KN Series cast iron boilers were purposefully engineered to live up to today’s toughest applications and challenges, providing versatility in boiler system configuration and installation without sacrificing the bottom line.

In this day and age, the word ‘hybrid’ gets thrown around often. But what about the terms ‘base load’ or ‘mixed-boiler? Within the commercial boiler market, the concept behind these configurations is simple, lower the upfront equipment cost of a complete condensing boiler plant by incorporating new units into an existing and less expensive non-condensing boiler plant.

With a hybrid boiler system that combines KN Series condensing boilers within an existing, non-condensing boiler plant, operators are able to meet total BTU requirements while optimizing overall system performance, increasing boiler efficiency under various climate, seasonal and load conditions. By operating during most of the heating season, the condensing KN Series units provide the bulk of the high-efficiency BTU output when loop temperatures are low, while the existing and less-efficient non-condensing units act as supplemental boilers when outdoor temperatures fall and boiler loop temperatures increase.

Aeroseal Duct Sealing at Iconic Wrigley Building

Wrigley Building, Chicago, IL – Completed 11/28/15

During a remodel of the 9th Floor of the Wrigley Building, when walls                             were torn down and the duct was exposed, the General Contractor was made aware of air pouring out of the duct work as a result of gaps causing leakage. The Aeroseal duct sealing method was used to reduce that leakage.

Initial Leakage: 430.2 CFM

Final Leakage: 31.4 CFM

RESULT: 92.7% Reduction in Leakage

TEC is in the Large Boiler Business!

TEC introduces a new commercial boiler line to our offering – KN from Advanced Thermal Hydronics (ATH).

Engineered to meet the demands of today’s commercial condensing boiler market, KN Series by Advanced Thermal Hydronics (ATH) are high efficiency condensing gas boilers built with the historically recognized reliability and strength of cast iron. As the first line of commercial boilers capable of realizing the full potential of cast iron, KN Series boilers take the heat-retention and durability of cast iron and couple it with the energy savings of fully modulating, highly efficient condensing boiler performance.

Capable of adapting to changing operating environments while generating 200,000 – 3,000,000 BTUs, KN Series boilers deliver environmentally friendly solutions for a wide range of boiler applications, all the while maintaining low fuel utilization and a small footprint. All KN Series models come equipped with HeatNet 3.0 boiler control software for precise system control through digital communication, and even have the option of remote monitoring through HeatNet Online.

Significant reductions in energy consumption, when coupled with low NOx and CO2 emissions, make KN Series’ complete line of cast iron, condensing gas boilers an environmentally friendly, cost-effective option that will last for years to come.

Go behind the scenes to see how KN Series boilers are made!

Aeroseal and its unique benefits

Aeroseal is a proven, patented technology that seals the duct from the inside out.Virtually every duct system has a substantial amount of duct leakage which has been accepted as a necessary evil in our industry. On average, commercial duct systems lose between 25-40% of heating & cooling energy through the duct work.

Features & Benefits of Aeroseal:

  • Reduces duct leakage by 90-95% – typical duct leakage rates are redces from 20-30%, down to 2-3%
  • Seals up to a 5/8” hole – seeks out and finds virtually every existing crack, hole or seam without removing existing duct wrap
  • Seals up to 10” of duct static
  • Saves Fan HP – A 15% leakage rate equates to a 40% increase is system fan HP
  • VERIFIABLE – as the duct is sealed, the system documents the initial leakage rate, the reduction in leakage and the final system leakage rate and graphs the sealing process in the final report
  • SYSTEM BALANCE – Supply, return and/or exhaust air is delivered to the spaces it was designed for. Reduces the practice of increasing sheaves and fan BHP to overcome system shortcomings
  • Durable – Aeroseal is warranted on commercial jobs for 3 years and has a life expectancy of 40+ years
  • Safe – Aeroseal emits no known carcinogens or toxic substances (MSDS attached)
  • Payback – Typical paybacks are between 2-7 years
