OVERVIEW

Need Immediate Cooling Where HVAC Falls Short? This 21,000 BTU Commercial Portable Air Conditioner Stabilizes Temperatures and Restores Control Fast

When cooling needs to happen quickly—and flexibility matters—this commercial portable air conditioner becomes a practical solution, not a backup plan. The Koldwave Model 7KK21 air-cooled portable is designed for situations where permanent HVAC can’t keep up, can’t be altered, or simply isn’t available. Those situations aren’t rare, especially in facilities that run hot, run full, or can’t afford downtime.

With a cooling capacity of 21,000 BTU, this unit fits a very usable range. It’s capable of supporting larger rooms, shared spaces, and areas with elevated heat from people or equipment, while remaining fully portable and non-permanent. Depending on heat load and layout, it typically covers 700 to 1,000+ square feet, giving operators added cooling without committing to construction or system changes.

The air-cooled design keeps deployment straightforward. Unit requires power and a path to exhaust hot air—nothing more. There’s no water connection to manage and no infrastructure to install. That simplicity makes the 7KK21 easy to move, quick to set up, and well-suited for temporary needs, emergency response, or spaces where cooling demands change over time.

FEATURES

• 21,200 BTU of Targeted Spot Cooling for High-Heat Areas
  Delivers powerful, localized cooling for rooms and zones where central HVAC can’t keep up—ideal for equipment rooms, temporary spaces, or crowded work areas without overcooling the entire building.

• Spot-Cool and Room-Cool Modes for Real-World Flexibility
  Switch between focused spot cooling and full room cooling using a dedicated thermostat, allowing the unit to adapt to changing layouts, loads, and usage throughout the day.

• Air-Cooled Design for Fast, Hassle-Free Deployment
  Requires only electrical power and a way to vent hot air—no water lines or plumbing—making it easy to deploy during outages, renovations, or emergency cooling situations.

• Dual Directional Nozzles with High Airflow Output
  Two adjustable cold-air outlets deliver up to 560 CFM, letting operators aim cooling exactly where heat builds up, whether that’s a rack, workstation, or patient area.

• Built-In Self-Diagnostic Controls with Clear Display
  The onboard control panel shows operating modes, set and room temperatures, and fault codes, helping staff identify issues quickly without guesswork or downtime.

• Designed for Continuous Commercial Use
  Features a double-shaft motor powering two blowers, internal fiberglass insulation, and rust-proof ABS panels—built to handle demanding environments like hospitals, warehouses, and industrial spaces.

• Mobility That Matches Changing Needs
  Heavy-duty twin-wheel casters make the unit easy to move between rooms or departments, supporting temporary cooling, seasonal demand, or shifting hot spots without installation work.

• Safety and Reliability Built In
  Includes compressor overload protection, high-pressure switch, anti-freezing thermistor, full drain tank switch, automatic restart after power loss, and an optional condensate pump with overflow protection for unattended operation.
