OVERVIEW

Battling Heat Build-Up or Winter Cold Spots? This Air-Cooled 18000 BTU Portable Air Conditioner and Heater Delivers Fast, Targeted Temperature Control Year-Round

When a space runs too hot—or suddenly too cold—there’s rarely time to wait for permanent HVAC fixes. That’s exactly where a portable air conditioner and heater earns its keep. The Koldwave Model 6HK16 Portable Heat Pump is built for those moments when conditions need to stabilize fast, without tearing into walls or rerouting ductwork.

This is not comfort cooling for a living room. It’s purpose-built, commercial-grade climate control that shows up when central systems fall behind, go offline, or simply weren’t designed for the load in the first place. You know the situations: a patient room that won’t stay within limits, a server rack creeping past safe temps, or a warehouse workstation stuck near a drafty dock door.

At roughly 18,000 BTU (1.5 tons), the capacity hits a practical middle ground. It’s strong enough to handle single rooms, small suites, equipment spaces, or focused zones without the inefficiency of oversizing. In healthcare environments, that means keeping treatment rooms, labs, and temporary overflow spaces within acceptable temperature ranges during maintenance or unexpected outages. In data centers or IT rooms, it means direct, close-coupled cooling where hot spots actually form—without dropping the setpoint for the entire building.

Here’s the thing: cooling alone isn’t always enough. Facilities don’t just battle summer heat; winter cold spots cause just as many issues. This commercial portable air conditioner includes heating capability, letting the same unit handle seasonal swings, uneven building heat, or edge spaces that fall outside the comfort envelope. One unit. Year-round use. Less scrambling when conditions change.

Because it’s air-cooled and mounted on casters, the 6HK16 rolls exactly where it’s needed. Exhaust heat can be ducted to a ceiling plenum, window, or return path—no outdoor condenser required. That flexibility matters in hospitals with infection-control constraints, in data centers with zero appetite for construction, and in warehouses where layouts change faster than HVAC plans ever could.

Warehouses, in particular, benefit from this targeted approach. Instead of conditioning the entire volume, teams can focus cooling or heating on packing lines, QC stations, or sensitive equipment. Worker comfort improves. Heat stress risk drops. And energy spend stays under control. Honestly, that balance is hard to ignore.

At the end of a long day, this portable air conditioner and heater is about risk reduction. It protects people, equipment, and processes when fixed systems can’t respond fast enough. And when you’re responsible for uptime, safety, or compliance, that kind of reliability isn’t a luxury—it’s a requirement.

SPECIFICATIONS

FEATURES

• 16,800 BTU Cooling / 18,500 BTU Heating for True Year-Round Control
  Handles both summer heat and winter cold spots with a single unit, eliminating the need for separate cooling and heating equipment while keeping critical spaces within safe, comfortable temperature ranges.
  
  
• Designed for Targeted Commercial Spot Conditioning
  Spot-Cool and Room-Cool thermostat modes let you condition specific rooms or zones up to ~355 sq ft, making it ideal for patient rooms, server spaces, labs, workstations, and equipment areas where central HVAC falls short.
  
  
• Air-Cooled, No Outdoor Condenser Required
  Heat exhausts through a 12″ duct (up to 50 ft) to a ceiling plenum, window, or return path—perfect for facilities where outdoor condensers or permanent installs aren’t possible.
  
  
• Plug-and-Play Power at 115V
  Operates on a standard 115V / single-phase circuit with a NEMA 5-20P plug, allowing fast deployment without electrical upgrades or downtime.
  
  
• Heavy-Duty Mobility Built for Real Facilities
  Mounted on twin-wheel industrial casters, the 230-lb unit rolls easily between rooms, letting teams respond quickly as hot or cold problem areas shift.
  
  
• Smart Controls with Built-In Protection
  Features thermostatic control, auto fan speed, self-diagnostics, and automatic restart after power loss, helping maintain stable conditions with minimal operator oversight.
  
  
• Engineered for Reliability and Equipment Safety
  Includes compressor overload protection, anti-freeze thermistor, high- and low-pressure sensors, and time-delay restart, reducing risk during continuous or emergency operation.
  
  
• Low-Maintenance Design for Daily Use
  Washable air filters, an internal condensate tank (3.17 gal.), and an optional condensate pump with overflow protection simplify upkeep in healthcare, IT, and industrial environments.
