Info & Guides

Description

The Hessaire MC37M Evaporative Coolers are a powerful and easily portable cooling solution for large areas up to 950 square feet. This upgraded evaporative cooler can be used in various places, including outdoors, indoors, and covered porches. You can select the evaporative cooler only, or choose the option that includes the evaporative cooler plus the handy storage cover designed for it.

 

Note: Evaporative coolers (swamp coolers) are most effective in dry climates with an average relative humidity of 50 percent or less.

Simple High Performance Design 

Featuring a simple-to-use design, the Hessaire MC37M 3,100 Cubic Feet Per Minute (CFM) Evaporative Cooler has simple rotary dial controls and a fixed palm fan grill design.

  • Three-sided high-grade cooling media cools areas faster
  • Automatic oscillation to cover wide spaces
  • Multiple cooling and fan speeds for customization

This simple, powerful cooler is a great option for smaller warehouses, repair shops, and other commercial spaces.

Control Panel

Simple upkeep and easy-to-operate rotary controls make controlling this air cooler a snap.

  • Motor Speed Dial: Turn on the cooler and select your fan speed between Low, Medium, and High with the fan switch.
  • Pump: Switch the pump on to saturate the internal Cooling Media.
  • Air Swing Delivery System: Turn the swing switch on or off for automatic oscillation.

Manual and Continuous Fill Options

Flexible water fill options are available to you when you have the swamp cooler indoors or outside near a garden hose. 

  • Manual Fill: Push on the spring-loaded front fill door for manual fill into the 10.3-gallon tank. Monitor water volume through the water level indicator. When the water limit hits “FULL,” start the internal water pump.
  • Continuous Fill: Assemble the continuous fill garden hose float adapter to the swamp cooler during assembly. The continuous fill method allows for a simple garden or coil hose connection that eliminates the need to manually watch and fill the water tank.

Powerful Airflow

Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you needed relief. Specially engineered features from Hessaire allow this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area:

  • The cupped axial fan design allows it to not only provide a strong airflow to thrust chilled air into your space.
  • The air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.
  • The Axial fan can be adjusted between three fan speeds: Low, Medium, and High. 

Additional Features

  • Fan-Only: Use the swamp cooler on one of the three fan speeds without water just to propel air throughout a stuffy room.
  • Cup Holder: The top cup holder is a great resting place for drinks.
  • Palm Design: Unique palm grill design provides an organic design.
  • Optional Cover: For additional protection, check out Hessaire's MC37/M150 Evaporative Cooler Cover. This durable cover features the Hessaire logo and provides rugged protection for the cooler.  

Sylvane's Expert Take

Whether you need to cool down indoor or outdoor spaces, the Hessaire MC37M Evaporative Coolers are affordable and versatile cooling solutions. Select the option that includes both the evaporative cooler and the cover. 

  • Use Anywhere: Sylvane customers use this evaporative cooler in a variety of places: garages, patios, sunrooms, workshops, outdoor kitchens, and even greenhouses.
  • Long Run Time: With the 10.3-gallon water tank, you’ll have three to four hours of continuous cooling. Hook it up to a water hose to constantly run without needing to refill.
  • Caster Installation: The durable casters are stored inside the unit for transportation and will need to be installed before the cooler's first use.

    Expectations Exceeded

    We have 2 standard window AC units that can only keep 2 rooms out of 5 cool. The front room would get in the 80's every evening and be unusable. This Hessaire MC37M has brought our home to comfortable levels again. It did exactly what we were hoping it would do. We're in Northern California with normally low humidity so it works great for us and improves our air quality. We're very happy with our purchase.

    Love our Cooler - Loved Sylvan's Price!

    Glad I compared prices as Sylvane's exact same Evaporative Cooler was $50.00 - $75.00 LESS expensive than Home Depot and Lowes! And it took no time at all to arrive. It works fabulously! We use it in our Garage so even with Vegas triple-digit temperatures we are comfortable while doing our projects. We have set up a little TV area in our garage with comfortable chairs that could not be enjoyed without our new Cooler.
