The Complete Guide to Swamp/Evaporative Coolers

An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles.

Because an evaporative cooler operates through the evaporation of water, it adds moisture into the air. Therefore it is not the best solution for cooling in humid environments, even though there are a number of benefits to Swamp Coolers:

Top 4 Benefits:

  1. Low installation and maintenance costs
  2. 75% less electricity usage
  3. Adds moisture to the air, for dry environments
  4. No ozone damaging refrigerants

The best thing about our coolers is that they are portable, come in a range of cooling capacities, and are the cheapest you will find anywhere. Visit our ISC Online’s Evaporative Coolers page for more information, or call us at 866-453-2700 and we will answer any questions you have.

3 Important Things About Mobile Fans

We are fanatic about our fans here at ISC. After an exhaustive vendor selection process, we’ve decided the superior TPI fans will be able to meet all of your air movement needs. But there are 3 things to think about when choosing which mobile fan to use.

1) Mount: Some fans are meant to blow in one direction while others can swivel to change direction easily. A standard mount fan is cheaper, but you might be unsatisfied with the direction of air.

2) CFM: Different fans will create more or less air movement based on how powerful they are. CFM stands for cubic feet per minute, which in laymen’s terms means the higher the CFM the more air is circulated.

3) Belt Driven vs. Direct Drive: both belt driven and direct driven fans have their good and bad points

  • Belt Driven: The motor exists independently of the fan blades and a belt connects the motor to the fan’s moving parts. Belt driven fans offer greater flexibility in terms of RPM speed, but tend to require more maintenance
  • Direct Driven: The fan motor that controls the movement of the fan blades is connected either to a shaft or fan axle. This configuration is more energy efficient, and more reliable, but tends to be more expensive.
