What is the difference between OWC3612, OWC3632, and OWC3634?

The difference is the power configuration. Cooling capacity is the same (3 ton). OWC3612 uses single-phase 208–230V, OWC3632 uses 208–230V 3-phase, and OWC3634 uses 460V 3-phase.

Does the OWC3612 require exhaust ducting?

No. Water-cooled portable air conditioners reject heat through the building water loop and do not require hot-air exhaust ducting.

Do I need a building water loop?

Yes. A supply and return water source is required for the OWC3612 to operate properly.

Where is the OWC3612 typically used?

Common applications include server rooms, telecom rooms, healthcare facilities, enclosed industrial spaces, and commercial areas where exhaust ducting is not possible.

Is the OWC3612 for whole-building cooling?

No. The OWC3612 is designed for spot cooling and high-load zones, not for full-building HVAC replacement.

Can you help me choose the right voltage model?

Yes. Provide your available voltage and phase, and we will match you with the correct model in the OWC36 lineup.

  The spot coolers provided Climage Control Solutions saved the day at my office when our central ac went out in the entire building. The portable ac units kept us all very comfortable for several weeks while we waited for ours to be repaired. It only took 2 units to cool quite a large space. Thanks you CCS!!! We appreciate you!
