Why Choose a Water-Cooled Portable Air Conditioner?
Traditional air-cooled spot coolers remove heat from a room and reject it through a separate stream of hot condenser air.
That heat typically needs to be directed away from the cooled area through suitable exhaust ducting or another ventilation arrangement.
The OceanAire OWC3612QC Series uses water to remove condenser heat.
This eliminates the need for a conventional hot-air exhaust duct and allows the unit to operate in suitable enclosed spaces where condenser water connections are available.
Water-cooled operation is particularly useful in commercial buildings, equipment rooms, and industrial facilities where installing or routing condenser exhaust ducting would be impractical.
Benefits of Water-Cooled Spot Cooling
- No conventional hot-air exhaust duct required
- High-capacity cooling for enclosed commercial areas
- Quick-connect water connections
- Three electrical configurations
- Built-in automatic condensate removal
- Compact portable cabinet
- Optional directional air-distribution accessories
Important: These units require a suitable condenser water supply, adequate water flow, and an acceptable condenser water outlet or discharge arrangement.
The units do not independently provide a closed-loop condenser water system.
Common Applications for the OceanAire 3-Ton QC Series
Server Rooms and Data Centers
Server rooms, network equipment, and telecommunications facilities generate substantial heat during continuous operation.
The OceanAire OWC3612QC Series can provide temporary or supplemental cooling for properly sized IT environments.
Its water-cooled condenser is especially useful in equipment rooms where conventional hot-air exhaust ducting would be difficult to install.
Common applications include:
- Emergency cooling during HVAC failures
- Supplemental server-room cooling
- Networking and telecommunications equipment rooms
- Temporary cooling during equipment replacement
- Cooling during IT infrastructure upgrades
Proper cooling-load calculations, electrical compatibility, water supply requirements, and condensate drainage should be confirmed before installation.
Read our Portable Spot Coolers for Server Rooms Guide.
Warehouses and Manufacturing Facilities
Manufacturing equipment and industrial processes can generate localized heat around production areas, workstations, and machinery.
The OWC3612QC Series provides approximately 3 tons of cooling for suitable industrial applications.
Potential uses include:
- Manufacturing equipment cooling
- Industrial workstations
- Assembly and packaging operations
- Maintenance rooms
- Equipment and process support areas
- Temporary HVAC replacement
Optional directional nozzle kits can help deliver conditioned air toward specific work areas.

Quick-Connect Water Fittings
The OceanAire OWC3612QC Series includes factory quick-connect fittings for condenser water supply, condenser water outlet, and condensate drainage.
Condenser Water Inlet — 3/4″ Quick Connect
The water inlet supplies water to the condenser, allowing the refrigeration system to transfer heat into the water stream.
A suitable water source must provide adequate temperature, pressure, flow, and water quality.
Condenser Water Outlet — 3/4″ Quick Connect
The outlet carries condenser water away after it has absorbed heat from the refrigeration system.
It must connect to an appropriate water discharge or return arrangement.
Condensate Drain — 3/8″ Quick Connect
The condensate drain removes moisture collected during cooling operation.
Each model includes a built-in automatic condensate pump with up to 20 feet of vertical lift.
A compatible condensate hose and drainage location are required.
Condenser Water Flow Requirements
The OWC3612QC Series uses condenser water to reject heat removed from the conditioned area.
Published estimated flow requirements include:
| Entering Water Temperature | Estimated Water Flow |
|---|---|
| 60°F | 2.2 GPM |
| 85°F | 9.0 GPM |
These estimates are based on the manufacturer’s published rating conditions.
Actual water usage depends on entering water temperature, operating load, and water conditions.
The units include a water-regulating valve to help control water flow during operation.
Before ordering, verify that the installation can provide suitable condenser water and an acceptable water discharge or return connection.
Electrical Requirements
The OceanAire 3-ton QC series includes three electrical configurations.
| Model | Electrical Service | Plug | Compatible Receptacle |
|---|---|---|---|
| OWC3612QC | 208–230V Single Phase | NEMA 6-20P | NEMA 6-20R |
| OWC3632QC | 208–230V Three Phase | NEMA L15-20P | NEMA L15-20R |
| OWC3634QC | 460V Three Phase | NEMA L16-20P | NEMA L16-20R |
All three versions require a properly rated electrical supply.
The 208–230V single-phase model includes an LCDI-protected electrical cord, while the three-phase models use locking plugs.
OceanAire recommends a dedicated circuit with appropriate time-delay fuses or circuit breakers.
Electrical requirements should be confirmed against the current equipment nameplate and installation documentation.
The three power configurations are not interchangeable. Always confirm available voltage and phase before selecting a model.
Built-In Automatic Condensate Pump
All three OWC3612QC Series models include an internal automatic condensate pump.
The pump provides up to 20 feet of vertical lift, allowing collected moisture to be routed to a suitable drainage location.
The unit also includes a condensate overflow alert.
Unlike portable spot coolers that require frequent manual tank emptying, these water-cooled units provide automatic condensate removal.
A compatible drain hose and acceptable drainage location are required.
