While it may never be possible for an HVAC contractor to chill out on the job, installing and servicing chillers continues to be easier and easier, as, according to several manufacturers, today’s chillers are being designed with the contractor in mind.

When it comes to large equipment that powers HVAC systems, the old saying “an ounce of prevention is worth a pound of cure” definitely rings true. And nowhere is an ounce of prevention more beneficial than with chiller maintenance.

For more than two decades, Entech Sales & Service in Dallas has offered HVACR professionals an in-depth look at centrifugal chillers, examining assembly, theory, microprocessors, and teardown training through a series of educational sessions heralded as some of the best nationwide.

Chillers are complex pieces of equipment and a lot of training and education is needed to keep contractors on the top of their games when dealing with this equipment. 

The chillers at Broward Health Medical Center were not achieving the kW per ton for which they were rated — a serious problem that they had not been aware of before, and which had probably cost them over $1 million in excess energy use since installation. 

It’s time again for the annual Cooling Showcase. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.

Featuring patent-pending SmartSpray™ technology, the PF2 induced draft counterflow closed-circuit cooling tower optimizes spray coverage to fully wet the coil. 

The chillers now feature low-voltage, unit-mounted Adaptive Frequency™ Drives (AFD) on units up to 3,000 tons. 

Only by using more advanced cooking and chilling technology can you ensure that your potato salad is fresh, delicious, and offers optimum shelf life, without the use of unappealing preservatives.
