XeteX Custom Made Air Handlers – A Success Story

On an unusually cold day in May, Imperial Crane was lifting three XeteX custom made air handlers to the 11th and 7th floors of the new Midwest HQ of a multinational technology company, located in the west loop of Chicago. The lifts were accomplished with the 2nd largest crane in the Midwest, a 550 ton monster that lifted these 20,000 lb units to their final destination. But we’re getting ahead of ourselves.

In the Beginning

This story began in the spring of 2014 when the engineering firm of Environmental Systems Design called their Temperature Equipment Corporation (TEC) salespeople, Mark Simbrowsky and Jose Ronchetta to give them ideas about meeting a new building guideline called the Living Building Challenge© with an air handler that could handle the requirements of this demanding job. TEC knew immediately who to turn to for the job; XeteX, based in Minneapolis, MN.

Design Requirements

Part of the Living Building Challenge© requires:

  • Ventilation rates must be designed to comply with ASHRAE 62 and equipment must be installed to monitor levels of carbon dioxide (CO2), temperature and humidity.
  • Conduct air quality testing at pre-occupancy and after nine months of occupancy to measure levels of Respirable Suspended Particulates (RSP) and Total Volatile Organic Compounds (TVOC).
  • Provisions must be made for future enhanced filtration such as carbon filters, or more advanced products such as Secure Aire.
  • Monitoring is required to provide occupants opportunities for improving indoor air quality over time. Maximum thresholds will not be used to test compliance with the Living Building Challenge, but are listed in the Dialogue for reference. A minimum of one test is required for each separate HVAC system installed.

Therefore AHU’s were designed with the addition of innovative IAQ solutions to help qualify. One such product is Global Plasma Solution’s bi-polar ionizations I-Bars. These devices create positive and negative ions that are distributed across the cooling coil and propelled into the space to reduce or eliminate RSP’s and TVOC’s. Plus there is room in each AHU to install, at a later date Secure Aire filtration systems that use Particle Acceleration Control Technology and MERV 15 filters to reduce or eliminate RSP’s and agglomerate particles in the space to reduce TVOC’s and any other particulates that may accumulate in the environment. Also, room was left for a cooling coil and the units were built for the addition of compressors and condensing section once the building was occupied.

The purchase order was awarded during the Christmas holiday and the units were released for production in early March. Lead time was a tight 10 weeks, which is unheard of for a custom made unit. Also the delivery had to be timed exactly because of the crane involved. Any missed date of production, shipment or weather would have resulted in a large crane charge.

Given all that could have gone wrong, the coordination efforts of all parties combined to make this job a show piece for everybody.


Carel USA Humidification & RenewAire Energy Recovery Ventilators

On June 9th TEC hosted an event sponsored by Carel USA Humidification and RenewAire Energy Recovery Ventilators. The day started out with the Carel van in the parking lot of U.S. Cellular field where several engineers and contractors learned how Carel could satisfy all their humidification needs.

Carel USA manufactures humidification products in Manheim, PA. They are the 3rd largest manufacturer in the world of humidifiers. Their systems range from 3 lbs/hr. to 12,000 lbs/hr. They manufacture products in two broad categories:

  • Isothermal (steam) using electricity or gas to generate steam
  • Adiabatic (pressure) using compressed air or centrifugal force to generate mist

Carel products have a variety of distribution methods ranging from spray nozzles to distribution pipes and manifolds.

They have a unique evaporative cooling system called Optimist that can be used in the summer time to reduce cooling needs and in the winter to meet humidification needs.

RenewAire manufactures products in Madison, WI. They use a heat exchanger that can transfer sensible as well as latent energy. Their efficiency approaches that of a wheel for energy recovery. Their ERV’s are self-contained and can handle up to 8,000 CFM and can go as high as 20,000 CFM when using modules with external fans. Their products can be used outdoors or indoors. RenewAire also makes combo curbs to use with Carrier roof top units.

They can operate down to -10 degrees without frosting and don’t need a condensate system. They are easy to clean, with the simple use of a vacuum cleaner.

Horizon Keystone Commercial Financing

What do you need to help sell a job these days? It’s not always low price as you might imagine. How about a way for your owner to afford to get the best for their job and for you to make a sale. Try Horizon Keystone Commercial Financing (HKCF). TEC’s exclusive way to arrange a low monthly payment for your owner who is might be on the fence about upgrading equipment or even going ahead with a project.

For jobs of $5,000 to $500,000 that need financing, HKCF does all the legwork. They will work with you or your client to gather all the paperwork and arrange a payment plan to close the deal. For example, for a job that you are charging $250,000 for (that includes equipment, labor, warranties, controls  and all other items you are bidding), the owner will pay a little less than $5,000/month for 60 months.

Check out their simple online calculator to determine the financing for your customer www.HVACfinancing.com. They have a great phone app to download for Apple and Android (Horizon Keystone Calculator). And unlike residential financing, there is absolutely no cost to you.

We just had one of our contractors sell a swim club in the suburbs. The owner paid a lot of money for the building, pools, etc. and he didn’t have enough for the PoolPak units to heat and cool the pool area. Our territory manager suggested financing and he called HKCF. They took it from there. The job sold for over $200,000.

Put the monthly payments on every quote you do. You never know, it might get a job.

TEC & RenewAire

Temperature Equipment Corporation and RenewAire (Madison, WI) have formed an exclusive partnership for Northeastern Illinois and Northern Indiana. TEC will be supplying the complete RenewAire line of ventilation products including residential and commercial ERVs (with and without blowers) and Dedicated Outdoor Air Systems. Sizes from 90 CFM to 9,000 CFM are available. Larger sizes are available for combinations with external blowers.

Since 1983, RenewAire has built its product line around a static-plate core that transfers both heat and humidity. This technology offers advantages such as, high year round energy performance along                                 with the simplicity, reliability and the positive airstream separation building owners demand. For this core technology, RenewAire has benefitted greatly from a strong technical partnership with Mitsubishi Electric’s Nakatsugawa Works.

In May of 2010, the Soler & Palau Ventilation Group acquired majority interest in RenewAire. Soler & Palau has, for over 60 years, been a world leader in ventilation. It boasts production facilities in Europe, Asia and the Americas. RenewAire plans to incorporate S&P air handling technology and products into our ERVs in order to bring to market the most energy efficient products possible.

RenewAire will be debuting a whole new line up of ventilation products and self-contained heating and cooling units in the spring of 2015.

Please stop by RenewAire’s booth at the 2015 AHR Expo – Booth # 1936.
