Today's Evaporative Coolers Are NOT Yesterday's Swamp Coolers - Here's Why

Posted by Melodie Elliott on Thu, Jun 02, 2016 @ 02:16 PM

Last week we talked about how evaporative coolers work.  Now let's explore WHY they work so well.

You may have heard the term ‘swamp cooler’ in the past used to refer to the process of using evaporation to cool an area. While evaporative coolers use the same general principles as antiquated swamp coolers, the technology of modern-day evaporative coolers has evolved to become much more energy efficient and effective.  It can be said that an evaporative cooler’s effective operation hinges squarely on technology of the evaporative media (e.g. the surface that collects the water). Quality evaporative media, manufactured in a trustworthy facility by expertly trained technicians, is an important element to selecting a long-lasting evaporative cooler. The best evaporative media features superior materials that are intelligently designed via a unique production technique that ultimately maximizes the interaction between air and water for superior cooling. 

Better Evaporative Media Matters

KUUL® evaporative media is the most advanced evaporative cooling media on the market and comes standard with every Portacool evaporative cooler we make. The KUUL Comfort™ series is made specifically to meet Portacool, LLC performance requirements and is 20% cooler than previously used evaporative media. It provides the highest efficiency cooling of any evaporative media on the market.KUUL-banner.png

The bottom line to you?  Today’s evaporative coolers are among the most energy-efficient cooling methods available thanks to the advances in technology, design and material.  Even better, most require the same amount of electricity used to run standard household appliances and operate for pennies an hour. Our Portacool products are made in the USA with domestic and global parts. We take pride in providing the most efficient evaporative cooler available.

A Refresher Course: What is Evaporative Cooling?

Posted by Melodie Elliott on Thu, May 26, 2016 @ 03:55 PM

Ah, the sultry days of summer are just around the corner. Depending on where you live, the mercury may already be rising. It is helpful to know your cooling options. Today, many people are familiar with traditional cooling methods ranging from air-conditioning (AC) to fans. AC works in closed spaces where the recirculated cool air can be maximized with use of refrigerant and a compressor. Fans – both oscillating and ceiling options - generate air but it is not chilled in any capacity.   

What about evaporative cooling? What is it exactly? Evaporative cooling is, quite simply, cooling with water.  A few relatable examples of evaporative cooling at work is the cooling sensation felt when climbing out of a swimming pool, perspiration as a form of natural cooling to the body or feeling the cool breeze blowing across a lake. By evaporating water, the temperature of the air in contact with the liquid water will lower as an endothermic reaction takes place.  During this reaction, the liquid water changes to a gas and the temperature of the air lowers. 

A portable evaporative cooler essentially works off this principle by acting as a cooling fan that uses water, a pump and a wetted surface to create the naturally occurring process of evaporation to cool warm air and drop temperatures.  By pulling air across water, the temperature of the air will lower.  A control system within the evaporative cooler operates the pump to assist in creating this effect and the fan distributes the cool air.



One unique aspect of the evaporative cooler is that it actually works best with a supply of outside ambient air to deliver a temperature reduction and cooling effects.  While evaporative coolers achieve significant temperature drops in more arid climates and drier spaces, they provide relief from the heat in any climate.  For example, in regions where relative humidity reaches 70% at midday with temperatures over 90 degrees Fahrenheit, evaporative coolers have been shown to offer noteworthy relief. Given that relative humidity is lowest in the afternoon when the temperature is at its highest, an effective evaporative cooling scenario is achievable.

Example: Evaporative coolers have been proven to deliver a temperature reduction from 8 to 10 degrees in the morning in the highest humidity regions (Miami, New Orleans, or Boston), and  up to 12 to 15 degrees later in the day when the  relative humidity goes down as the temperature goes up.

The technology at the center of an evaporative cooling system is the evaporative media (e.g. the surface) that collects water. Air passes through the media and is cooled as the water evaporates. The evaporative media is specially treated to prevent deterioration and ensure a long service life.  A special water distribution system spreads water over the surface of the media within the cooling unit to ensure a uniform water supply.  This keeps the entire air to contact surface thoroughly wet. A control system operates the water pump and distributes the cool air.  What difference does this evaporative media make? We’ll take a deeper look at that in next week’s post. Stay tuned.

Tips for staying safe in the heat at home

Posted by Melodie Elliott on Thu, Jul 09, 2015 @ 04:30 PM

This summer, we've talked a lot about heat safety relative to work environments. But, enjoying fun in the sun is one of the great pastimes of summer when you are at home.

It’s important to protect yourself from sun and hot weather while you’re outdoors. Normally, the body cools itself by sweating, but when the weather is particularly hot and humid, you may not sweat enough to keep yourself cool. When one’s body temperature increases too much, heat-related illnesses can occur. These range from minor irritations like heat rash or cramps, to potentially deadly conditions like heat exhaustion and heat stroke. In fact, each year, heat-related illnesses claim an average of more than 100 lives, according to the National Weather Service. Thousands more seek medical treatment for heat-induced injury and illness.

Here are a few tips  to keep yourself and your loved ones safe this summer:

* Choose your outdoor time wisely. Whenever possible, avoid spending time outside during the hottest parts of the day, typically noon to 5 p.m. Choose outdoor activities that you can enjoy in the early morning or evening, such as grilling and dining al fresco or going for a walk. 

* Keep everyone hydrated. When the weather is hot, it’s more important than ever to ensure everyone in the family – from children and pets to parents and grandparents – gets enough water. While outdoors, be sure to have ample bottled water on hand and don’t forget to keep your pet’s bowl filled—and give him plenty of opportunities to drink—while outdoors.

* Leverage cooling technology to make outdoor spaces more comfortable. Sometimes, you have to be outside during hotter times of day. Keeping cool is key. Outdoor coolers like the Portacool Cyclone 1000, use the natural process of evaporation to make outdoor spaces more comfortable during hot weather. These evaporative coolers move water over evaporative cooling pads (or evaporative cooling media) to produce chilled air that provides a noticeable difference – lowering temperatures by as much as 30°F. This can make outdoor spaces such as the patio, deck or garage more bearable in the heat. 

* Seek shade. If your patio or deck isn’t covered, use movable umbrellas or awnings to create plenty of shade. Going to a ballgame or the beach? Take an umbrella to shield you from the sun, or wear a wide-brimmed hat to keep the sun off your face.

* Choose weather-smart attire. When the weather’s very hot and the sun is bright, choose loose-fitting clothing made from lightweight materials and opt for lighter colors. This type of clothing will be more comfortable when you sweat, and lighter colors reflect heat more efficiently. If you’ll be working outdoors for any length of time, consider long-sleeved shirts and long pants in moisture-wicking materials to help shield your skin from sun exposure.

* Don’t overdo it with exercise. While vigorous exercise has many benefits, engaging in strenuous activity in extreme heat can do far more harm than good. If you enjoy an outdoor run or have yardwork to do, try to reserve it for the coolest times of day—early morning and evening. Consider taking your exercise routine indoors to a gym or your own living room when temperatures are very hot.
