Tips for Handling the Heat

As I talk with customers throughout the nation, without exception they say it’s hot where they are. The oppressive heat wave we are experiencing presents the peril of heat exhaustion. While heat exhaustion is not particularly dangerous in itself, it’s not something to be taken lightly. Without proper intervention, heat exhaustion can progress to heat stroke, which can damage the brain and other vital organs, and even cause death.

There are two types of heat exhaustion:

Water depletion. Signs include excessive thirst, weakness, headache, and loss of consciousness.

Salt depletion. Signs include nausea and vomiting, frequent muscle cramps, and dizziness.

If you, or anyone else, has symptoms of heat exhaustion, it’s essential to immediately get out of the heat and rest, preferably in an air-conditioned room. If you can’t get inside, try to find the nearest cool and shady place.

– Drink plenty of fluid (avoid caffeine and alcohol).

– Remove any tight or unnecessary clothing.

– Take a cool shower, bath, or sponge bath.

– Apply other cooling measures such as fans or ice towels.

 If such measures fail to provide relief within 30 minutes, contact a doctor because untreated heat exhaustion can progress to heat stroke. After you’ve recovered from heat exhaustion, you’ll probably be more sensitive to high temperatures during the following week. So it’s best to avoid hot weather and heavy exercise until your doctor tells you that it’s safe to resume your normal activities.

Gatorade®   has launched a Beat the Heat campaign. Their goal is to educate athletes, parents, and coaches about the importance of proper hydration to reduce heat-related illnesses during physical activity. It is free for the download at http://www.gatorade.com/pdf/BTH_safety_kit_5_24_13.pdf

EXAIR recognizes the risk that heat presents to our shop employees. We have moved their starting work hours to an earlier time, providing bottled water, ice, and popsicles. The customer still comes first, so we have  manned the shipping department on a rotation.

Please be safe. We value your good health.

High Temperature, Dual Cabinet Cooler Systems Make the Grade for Extreme Duty Operation

HTDCC

EXAIR Corporation and our products have a robust presence in many overseas places. I should know. I work directly with many of our overseas clients, especially in the Middle East region where just the ambient temperatures climb to 60°C (140°F). If you take that high heat ambient condition and throw in the fact that our customers are working in petrochemical, chemical, cement, glass and plastic industries, the conditions in these manufacturing plants can be torturous not only to personnel but also to the many cabinets which reside in these processes.

I am working presently with a customer in Saudi Arabia who specializes in production of specialty pipe products which combine glass-fiber, resin and sand to produce pipes which can withstand highly corrosive and/or abrasive applications. When you have these kinds of raw materials moving around a production environment, you not only have the issue of high heat conditions, but also the egress of these fine materials into various panels causes many pre-mature failures. As many of us know, housekeeping will usually take a back seat to production. So, the customer is looking for a solution that can keep their panels cool enough to operate and also provide a means to keep a positive pressure to keep these raw materials from migrating inside their panels.

The specific application we are starting with is a panel located very near to where the sand charge is dumped into a mixer to be combined with the resin. The cabinet size is 1200 mm (h) X 1200 mm (W) X 400 mm Depth. The temperatures in this area get up to 60°C and with his internal heat load, his cabinet is getting up to 51°C under present conditions. I asked the customer to fill out a Cabinet Cooler Sizing Guide for me so I could have all the data necessary to run heat load calculations for him. We performed the calculations and came up with 1,170 Btu/hr. that he needed in this case.

After determining the heat load, I evaluated our available HT Cabinet Cooler models and settled on one of the Dual Cabinet Cooler systems to provide them with trouble-free cooling. The specific model was HT4360-240 (NEMA 12, High Temperature, Dual Cabinet Cooler System with 240 VAC thermostat control).

Since this is a technology that the customer was not familiar with prior to our contact, he is exercising prudence and has installed one unit for the time being and is evaluating its performance. This is a fairly new installation. So far, the customer has been satisfied with the performance.

Cabinet Cooler Systems can withstand very demanding applications like the one above. With proper selection and guidance from our experienced Application Engineering staff, you can be assured of similar, good performance in your application as well.  Present us with your challenging application today!

Like a Donkey Between Two Haystacks

90Day_Temp

Having been born and raised in the northern climates, for me 80 degrees is hot. So when temperatures soar into the 90’s I really struggle to cope. Bad news is that according to NOAA, we are in store for above average temperatures for the remainder of the summer!

High temperatures are not only uncomfortable for we humanoids, electronics suffer as well. The demand for panel cooling is extensive and my company, EXAIR, produces Cabinet Cooler systems. There in lies my dilemma. I would like to wish for the heat to go away but then that would be wishing ill for my company. I’m like a donkey trying to decide between two hay stacks.

So, I will stay in my air conditioned cubical and calculate cooling requirements for customers. I would welcome the opportunity to assist you with your panel cooling requirements. Give me a call at 1-800-903-9247

Dog Days of Summer

Conventional conjecture is that the term Dog Days of summer has some sort of reference to our canine friends.  Actually the term came from ancient Rome, named after the star Sirius, the Dog Star, which is the brightest star besides the sun. Romans speculated that due to the rising and setting of Sirius at around the same time of the sun each day this time of year, that Sirius added it’s heat to the sun’s heat, thereby making the days hotter. Hence the term Dogs Days.

This summer got off to a slow comfortable start but has since rolled in with a vengeance as temperatures have reached the triple digits! The extreme heat definitely presents a hardship, especially on computerized equipment. Although electronics are generally designed for environments of 104 degrees F, trying to cool a panel full of heat generating electronics with a fan pulling in triple digit air is not going to get the job done.

EXAIR provides a solution.   A simple device, operated with compressed air, and small enough to fit in the palm of your hand. These Cabinet Cooler systems come in NEMA 12, NEMA 4, and NEMA 4x ratings in cooling capacities ranging from 550 Btu/Hr. up to 2800 btu/hr. and for very heavy heat loads they are available in a  dual cooler configuration up to 5600 Btu/Hr.

Don’t know how much cooling you need? EXAIR has a staff of engineer that will help you with that. Just give them a call at 1-800-903-9247.
