OVERVIEW

Trying to Cool a Large Dock or Staging Area? This 24 inch Portable Evaporative Cooler Delivers Wide Coverage and Strong Airflow

When heat spreads across a large dock, a long packing line, or a bank of machines, small fans barely make a dent. And cooling the entire building with AC? For most warehouses and plants, that’s not realistic. A powerful portable evaporative cooler like the Power Breezer E780L solves that problem by focusing cooling exactly where the work happens.

This unit is built to create a wide, mobile cool zone instead of trying to condition the whole structure. With 7,800 CFM of airflow and a 24-inch fan, it pushes a steady stream of cooled air deep into active work areas. The result feels immediate — crews standing 30, 40, even 50 feet away can still feel the difference.

Large industrial spaces don’t trap air the way offices do. You’ve got open dock doors, tall ceilings, forklifts moving nonstop, and heat rising all day. A portable evaporative cooler works with that environment, not against it. It pulls in fresh air, cools it through evaporation, and moves it across a big zone where people are actually working.

At this airflow level, one unit can cover a wide stretch of floor space — often around 1,500 to 2,000+ square feet depending on layout and ceiling height. That makes it a strong fit for shipping areas, long conveyor lines, staging zones, and clustered workstations where heat tends to build and linger.

And honestly, that size matters. Higher CFM helps push cooled air around racking, pallets, and machinery. It keeps air circulating in high-bay buildings where heat gets trapped overhead. Instead of cooling just one bench, this evaporative cooler helps support an entire section of the floor.

There’s also the cost side to consider. Traditional AC systems rely on compressors and sealed air. They’re expensive to install, expensive to run, and not always effective when doors stay open. A portable evaporative cooler runs on water and airflow, using far less electricity while still creating noticeable temperature drops in hot, dry to moderate conditions.

Mobility is another big advantage. Production lines shift. Workloads change. Heat moves during the day. The E780L can be rolled to the hottest zone — a dock in the afternoon, a staging area during peak season, or a fabrication cell running overtime. It adapts as the facility changes, which is something fixed systems just can’t do.

The Power Breezer E780L portable evaporative cooler gives operations a practical way to manage heat across larger industrial zones without the cost and complexity of whole-building air conditioning. It’s a straightforward approach — move more air, cool the space where people stand, and make the workday feel more manageable.

SPECIFICATIONS

FEATURES

• High-Volume 7,800 CFM Airflow for Large Zone Cooling
  The 24-inch fan paired with a .85 HP motor moves a powerful stream of air across wide areas, helping cool spaces up to nearly 2,000 sq ft. Ideal for loading docks, production lines, and large work cells where heat tends to build and linger.
  
  
• Built for Bigger Industrial Spaces With Tall Ceilings
  This unit is sized to create a noticeable cooling zone across multiple workstations, not just one bench. Strong airflow helps push cooled air around racking, machinery, and open bays so more people feel the impact.
  
  
• Long Run Time With 30-Gallon Tank + Auto Water Supply
  The integrated tank supports extended operation without constant refilling, while the automatic water feed option keeps the system running during long shifts. That means less downtime and more consistent cooling throughout the day.
  
  
• Portable, Compact, and Easy to Reposition
  Despite its high output, the cooler’s balanced footprint (43.4 × 23.4 × 53.2 inches) and wheeled design make it easy to move between hot spots. Roll it to a dock in the afternoon, a staging area during peak hours, or wherever heat becomes a problem.
  
  
• Energy-Efficient Cooling Without Compressors or Refrigerant
  This evaporative system uses water and airflow instead of gas or heavy mechanical components, keeping power consumption low on standard 110–120V service. It’s a practical option for facilities that need cooling without the high operating cost of traditional AC.
  
  
• Industrial-Ready Features for Demanding Environments
  Equipped with a centrifugal fan, 3 speed settings, built-in ionizer, and an 8.2-foot grounded power cord, this unit is designed for daily use in machine-driven spaces. Durable construction and steady airflow make it a strong fit for warehouses, factories, and busy workshops.
