The OceanAire OWC1811QC 1.5-Ton Water-Cooled Portable Air Conditioner delivers 18,000 BTU/hr of commercial-grade cooling for offices, server rooms, equipment rooms, manufacturing facilities, and temporary HVAC applications. Featuring quick-connect water fittings, this portable water-cooled spot cooler eliminates the need to route hot condenser exhaust air through a ceiling panel or ventilation duct.
Operating on 115V / 60Hz single-phase electrical power, the OWC1811QC combines a 1.5 HP rotary compressor, 600 CFM of conditioned airflow, electronic temperature controls, and a built-in automatic condensate pump with up to 20 feet of vertical lift.
Its compact cabinet measures just 21.5 inches wide and 16 inches deep, making it useful for commercial environments where available floor space is limited.
The water-cooled refrigeration system requires a suitable condenser water supply and discharge connection. Optional quick-connect hose kits and adapters simplify integration with compatible water connections.
Whether you need supplemental cooling for an IT room, temporary air conditioning during HVAC maintenance, or targeted cooling for industrial equipment, the OceanAire OWC1811QC offers portable cooling without a conventional hot-air exhaust duct.

Why Choose a Water-Cooled Portable Air Conditioner?
Traditional air-cooled spot coolers remove heat from a room and reject it through a separate condenser-air stream.
That warm discharge air often needs to be directed through a ceiling kit, window adapter, or exhaust duct.
The OceanAire OWC1811QC uses a different approach.
Its condenser transfers heat to a water stream, allowing the unit to provide cooling without a conventional hot-air exhaust duct.
This makes it useful for enclosed commercial environments where suitable water connections are available but condenser exhaust ducting would be inconvenient.
Benefits of Water-Cooled Spot Cooling
- No conventional hot-air exhaust duct required
- Compact equipment footprint
- Suitable for enclosed commercial spaces
- Quick-connect condenser water connections
- Portable installation with appropriate water supply and discharge
- Built-in condensate management
Important: Water-cooled operation requires a compatible water supply, sufficient flow, and an acceptable method for handling the outgoing condenser water.
The unit is not a closed-loop system by itself. Any recirculating water arrangement must be designed with suitable external equipment.
Common Applications for the OceanAire OWC1811QC
Server Rooms and IT Equipment Cooling
Server rooms, network closets, and telecommunications facilities generate heat during continuous equipment operation.
The OceanAire OWC1811QC can provide temporary or supplemental cooling for properly sized IT spaces.
Its water-cooled condenser is particularly useful where conventional air-cooled spot cooler exhaust ducting is impractical.
Applications include:
- Temporary cooling during HVAC maintenance
- Supplemental cooling for networking equipment
- Server and communications rooms
- Emergency IT equipment cooling
- Localized cooling during equipment upgrades
An appropriate condenser water connection, condensate discharge location, and reliable electrical supply must be available.
Read our Portable Spot Coolers for Server Rooms Guide.
Commercial Offices and Retail Spaces
Commercial offices, retail stores, institutional facilities, and other indoor workspaces may need additional cooling during warm weather or HVAC maintenance.
The OWC1811QC provides targeted cooling for suitable spaces without requiring hot-air exhaust ducting.
Its 115V electrical configuration and compact cabinet make it practical where compatible power, water connections, and drainage are available.
Manufacturing and Industrial Equipment Rooms
Manufacturing equipment and industrial processes can create concentrated heat around workstations and machinery.
The OceanAire OWC1811QC can supply localized cooling for suitable light-industrial environments, maintenance areas, and equipment spaces.
Optional directional nozzles can help direct cooled air toward a selected location.
Temporary and Emergency HVAC Applications
The OWC1811QC can support temporary cooling during:
- Commercial HVAC repairs
- Equipment maintenance
- Office renovations
- Temporary IT installations
- Seasonal supplemental cooling
- Emergency air conditioning failures
Because it requires condenser water connections, installation suitability should be confirmed before deployment.

Quick-Connect Water Connections
One of the primary advantages of the OceanAire OWC1811QC is its factory quick-connect water fitting arrangement.
The unit includes three separate connections:
Condenser Water Inlet — 3/8″ Quick Connect
The inlet supplies water to the refrigeration system’s water-cooled condenser.
The water source must provide suitable flow, pressure, temperature, and water quality according to the manufacturer’s requirements.
Condenser Water Outlet — 3/8″ Quick Connect
The outlet carries condenser water away from the unit after it has absorbed heat from the refrigeration system.
The outlet must be connected to an acceptable return or discharge arrangement.
Condensate Drain — 1/4″ Quick Connect
The condensate drain removes moisture collected by the evaporator.
The OWC1811QC includes an internal automatic condensate pump with up to 20 feet of vertical lift.
Condensate must be routed to a suitable drainage location.
Condenser Water Requirements
The OceanAire OWC1811QC uses condenser water to remove heat from the refrigeration system.
Published estimated water requirements include:
| Entering Water Temperature | Estimated Flow |
|---|---|
| 60°F | 1.1 GPM |
| 85°F | 4.5 GPM |
These figures are based on the manufacturer’s stated test conditions.
Actual condenser water consumption varies with water temperature, operating conditions, and cooling demand.
A suitable water supply and discharge arrangement must be available before operating the unit.
Electrical Requirements
The OWC1811QC operates on 115V / 60Hz single-phase power.
It uses a NEMA 5-15P plug with LCDI protection.
Published electrical specifications include:
- Rated Current: 11.3 Amps
- Inrush Current: 69 Amps
- Power Consumption: 1,300 Watts
- Plug Type: NEMA 5-15P
OceanAire recommends a dedicated electrical circuit with appropriately rated time-delay fuses or circuit breakers.
Confirm electrical compatibility with the current equipment nameplate before installation.
Built-In Automatic Condensate Pump
The OWC1811QC includes an internal automatic condensate pump.
Unlike portable air conditioners that rely on a manually emptied condensate tank, this unit can automatically discharge collected moisture through its 1/4-inch quick-connect drain connection.
The manufacturer’s published pump lift is up to 20 feet vertically.
The system includes a condensate overflow alert for added protection.
A compatible drain hose and appropriate drainage location are required.
