Common Applications for the Oceanaire OWC3612
Server Rooms and Data Center Cooling
Server rooms, networking closets, and telecommunications facilities generate substantial heat from continuously operating equipment.
Traditional portable air conditioners require a way to discharge hot condenser air, which may not be practical in enclosed IT environments.
The Oceanaire OWC3612 eliminates the need for hot-air exhaust ducting by transferring condenser heat through a water supply and return system.
With 36,100 BTU/hr of cooling capacity, it can provide temporary or supplemental cooling for suitable IT equipment rooms.
Common applications include:
- Emergency cooling during HVAC failures
- Supplemental cooling for server racks
- Temporary cooling during HVAC maintenance
- Telecommunications and networking equipment rooms
- Cooling during equipment replacements and facility upgrades
Proper cooling-load calculations, water-system compatibility, electrical service, and airflow management are essential before deployment.

Warehouses and Manufacturing Facilities
Manufacturing equipment, production processes, and industrial machinery can generate concentrated heat in specific areas.
The OWC3612 provides targeted cooling for equipment rooms, workstations, assembly areas, and other commercial environments.
Its water-cooled design is particularly useful for facilities with an appropriate water source but no convenient location for discharging hot condenser air.
The unit’s locking casters allow it to be repositioned as operational requirements change.
Healthcare Facilities and Laboratories
Healthcare support areas, laboratories, institutional facilities, and enclosed commercial workspaces may require supplemental cooling during equipment maintenance or unexpected HVAC failures.
The Oceanaire OWC3612 provides a portable cooling option for suitable environments where traditional exhaust arrangements would be difficult.
Installations in healthcare and laboratory environments should be reviewed for applicable facility and environmental requirements.
Temporary and Emergency Commercial Cooling
Unexpected HVAC failures can interrupt operations and expose equipment to elevated temperatures.
The OWC3612 provides temporary cooling during maintenance, building renovations, equipment replacement, and other commercial applications.
Its 3-ton capacity offers a middle ground between smaller 1–2 ton portable spot coolers and larger 5-ton water-cooled systems.

How Does the Oceanaire OWC3612 Water-Cooled System Work?
Unlike conventional air-cooled portable air conditioners, the OWC3612 uses a water-cooled condenser to remove heat.
During operation, the unit draws warm room air across its evaporator coil and delivers cooled air back into the conditioned space.
Heat absorbed by the refrigeration system is transferred to water passing through the condenser. The warmed water then leaves through the return connection.
This eliminates the need for conventional hot-air exhaust ducting.
However, the OWC3612 requires a suitable water supply and return or discharge arrangement. It cannot operate as a self-contained portable air conditioner without access to condenser cooling water.
Water Flow Requirements
The required condenser water flow depends on the entering water temperature.
Published specifications include:
- 2.2 GPM with 60°F entering water
- 9.0 GPM with 85°F entering water
Water flow, pressure, temperature, and discharge arrangements must be appropriate for the installation.
A suitable building water system, approved supply and drain arrangement, or another compatible condenser water source may be used, subject to manufacturer and facility requirements.
Water Connection Sizes
The standard OWC3612 features:
- Water Inlet: 5/8-inch male flare
- Water Outlet: 5/8-inch male flare
- Condensate Drain: 3/8-inch male flare
Compatible water hoses and adapters may be needed depending on the available plumbing connections.
For applications requiring faster hose connections, consider the Oceanaire OWC3612QC Quick Connect Model.
Electrical Requirements
The Oceanaire OWC3612 operates on 208–230V / 60Hz single-phase electrical service and uses a NEMA 6-20P plug.
The published specifications list:
- Rated current: 12.0 amps
- Inrush current: 100 amps
- Power consumption: 2,700 watts
A compatible receptacle and properly rated circuit are required. OceanAire recommends a dedicated circuit and appropriate time-delay circuit protection.
Built-In Condensate Pump
The OWC3612 includes an internal automatic condensate pump.
The pump provides up to 20 feet of vertical lift and includes an overflow alert to help protect against excessive condensate accumulation.
Condensate must be discharged to an appropriate drainage location.
Optional Accessories for the Oceanaire OWC3612
The Oceanaire OWC3612 can be used with accessories designed to support water connections, air distribution, and temporary cooling installations.
Water Supply and Return Hoses
The standard OWC3612 requires compatible hoses for its 5/8-inch male flare inlet and outlet connections.
Water hoses should be selected based on connection type, hose length, pressure requirements, and the intended water source.
Contact Climate Control Solutions for compatible hose assemblies and installation accessories.
Oceanaire OWC3612QC Quick Connect Model
For customers who frequently install, disconnect, or move portable cooling equipment, the OWC3612QC provides an alternative configuration with Quick Connect water fittings.
The Quick Connect version offers the same nominal 3-ton cooling capacity but uses a different connection arrangement.
Unlike the standard OWC3612’s threaded flare fittings, the QC model features 3/4-inch quick-connect water inlet and outlet fittings.
Additional Water-Cooled Cooling Equipment
Climate Control Solutions offers additional water-cooled portable air conditioners for applications requiring different cooling capacities.

Why Choose the Oceanaire OWC3612?
The Oceanaire OWC3612 combines commercial-grade cooling capacity with the installation advantages of a water-cooled condenser.
Its 36,100 BTU/hr cooling capacity makes it useful for applications that require more output than smaller portable air conditioners but do not need a full 5-ton system.
Because it rejects heat through water, the OWC3612 can operate in enclosed commercial environments without conventional hot-air exhaust ducting.
The built-in condensate pump, electronic controls, washable filter, and locking casters provide additional convenience for commercial applications.
