ASHRAE Day 2 I Darrin Brady shares a few thoughts live from the event!

Posted on by Kele Inc

Day 2 was jam-packed with one-on-one business meetings, product showcases, and technical tours. The size of this event is incredible. I continue to be impressed by the crowds! I am confident this event will spark some of the biggest deals in the HVAC and BAS industry in 2018!

Being the leading distributor in the BAS market requires many points of contact with suppliers, manufacturers, and customers at events like the AHR 2018 Expo. The entire Kele executive team, along with our sales directors, product managers, and the new outside sales team are at the show to bring back the information you need to be successful. As the manufacturers continue to push out new and innovative products, Kele is here to make sure we are ready to serve and support you.

Some of the newest products, technologies, and innovative changes are listed below. A few of these items are already available in the Kele portfolio! Be on the watch for the others to come!

Have questions or comments about the show or products mentioned? Comment below and we’ll get you an answer!

In case you missed it, don’t forget to check out Day 1 at ASHRAE here.

Live from ASHRAE! Kele Product Manager, Darrin Brady, shares a few thoughts on Day 1!

Posted on by Kele Inc

Kele is here at ASHRAE looking for the latest and greatest products and technologies to serve you! If you couldn’t make it to the show this year, we’ve got you covered. Our goal is to meet with companies and uncover new ways to make your job easier. If you are at the show, we hope to chat!

It is no surprise that the conference boasts a whopping 65K in attendance, including 2K vendors! Day 1 was fantastic, and the crowd was excited!  The Internet of Things was a hot topic with both vendors and key speakers. As for new products and technologies associated with the Internet of Things, all I can say is “Wow!”

 

There are several “cool” (pun intended!) thermostats with BACnet technology featured at the show this year. They enable individuals to control temperature devices remotely. I cannot wait to share more about the topic of cloud controlled monitoring devices when I return. And that is just the tip of the iceberg! 

 

Stay tuned…in partnership with our suppliers, we will be bringing back a ton of new ideas!

Tech Talk: do you have a product that provides manual override if the controller does not support override capability?

Posted on by Kele Inc

 

Most people that call Technical Support are aware of popular Functional Devices’ products like RIB® relays, current sensors, power supplies and transformers, but we offer many other products that do not fit into one of those categories. In this blog, I will spotlight one such product, model RIBMNA1D0.

Features

The RIBMNA1D0 is a track mountable, manual analog override switch, and it provides override feedback to a controller. This product allows the user to make manual adjustments to the control signal for an end device at the point of use, instead of back at the controller, which is great for testing and maintenance purposes. It offers four different analog output ranges (0-5Vdc, 0-10Vdc, 0-15Vdc and 0-20mA) selectable by jumpers, which will cover most analog control scenarios.

Function

The controller’s analog output would connect to the RIBMNA1D0’s Signal (+) and Signal (-), and the Output (+) and Output (-) would connect to the device being controlled. The jumpers would then be set to match the analog signal coming from the controller. In Auto mode, the device passes the signal from the controller on to the end device, and the Feedback contact will be Open. When manual override is needed, the switch is put in the Manual position, and the Feedback contact will Close. Now the analog signal to the end device is being generated by the RIBMNA1D0, and it can be adjusted with the on-board potentiometer. The LEDs on the board indicate the percentage of full scale that the output is at.

If the need for a manual analog override ever pops up in one of your projects, this product is just for you.

“I was attracted to Kele because of the energy of the team and the momentum around creating a world-class customer experience, not yet seen in the building automation industry,” Benson said.

“I could not be more thrilled for Rob to join the Kele team. His experience leading high performing sales teams along with his knowledge of the HVAC construction process will enable Kele to deliver game-changing solutions for our customers in 2018,” said president and chief executive officer of Kele, Richard Campbell.

 

How Belimo butterfly control valves are helping mushrooms grow

Posted on by Kele Inc

In the production plant of Kuhn Champignons AG, seven to eight tons of mushrooms are produced daily. To accelerate the growth, an artificial “autumn climate” is created. Under the ideal temperature and humidity, the mushrooms grow, ripen and become ready for harvest within three weeks.

But after 30 years, the existing plant and hydraulics were obsolete and no longer met the current standards of sustainable production. Therefore, the entire plant had to be renewed for the purpose of saving energy and switching to variable amounts of water. Read more

Tech Talk: Air Capacity and Consumption – Choosing Electronic to Pneumatic Transducer

Posted on by Kele Inc

When it comes to selecting an electronic to pneumatic (E/P) transducer, the type of input and the pressure range of the output are the most common selection criteria considered. There are a couple of other specifications that are worth reviewing to select the best transducer for the job. These additional specifications are Air Consumption and Air Capacity. Read more

Tech Talk: Demand Control Ventilation

Posted on by Kele Inc

How many sensors are required in a typical installation? Where should they be located?

The number of zones with different occupancy patterns should dictate the number of sensors. In a small office application, for example, it would be ideal to have a sensor in the office space and one in the conference area. Carbon dioxide distribution in a space is influenced by the same factors that influence temperature distribution. These factors include convection, diffusion and mechanical air movement. Much like temperature sensors, placement of CO2 sensors should be based on the zone to be controlled and anticipated loads (e.g. common occupancy density and patterns). For optimum control, there should be a CO2 sensor placed in every location where temperatures controls are used. If an HVAC system is serving a series of zones with similar occupancy patterns, sensors placed in the return air ducting may be appropriate. Read more

A simple approach is the future of building automation systems

Posted on by Kele Inc

Thanks to improved wireless networking technology and standardized communication protocols, it’s easier than ever to collect data from sensors. Plus, silicon chips continue to get cheaper, faster and better and can be located in valves, actuators, thermostats and wall outlets to provide more memory and faster computing.

With the Internet of Things (IoT) continually expanding and easier access to cloud computing, it’s possible to transmit information, crunch numbers and use data like never before.

That means it’s time to take a fresh look at every element of a building — from small electrical switches, door locks and lights to massive chillers and boilers — as a way to gather and share information.

Most importantly, we need to re-examine the role of building automation systems (BAS) to enable the data and technology to merge and seamlessly solve problems in innovative ways, especially in smaller buildings.

Tech Talk: High Output Voltage for Transformers

Posted on by Rachel Guenther

Q. My 75 VA 120:24 volt control transformer has a high output voltage. It reads as high as 28.3 volts with a 123 volt input. The load is only 8 VA on the transformer. Why is the output voltage so high?

A. A control transformer will have a higher output at a no-load or low load condition. A typical transformer with a 24 or 25 volt secondary rating will output 28 to 29 volts with no load. As the load increases, the output will lower to rated voltage at a full load. You need to either add load to the existing transformer or use a smaller VA transformer.
