Description
Standard 115V shore power gets the CTM EV-12 evaporator, sized to pair with a 12,000 BTU condenser for boats running the most common US electrical setup. It’s a direct drop-in replacement for the Dometic TVE evaporator, moving air through mid-sized cabins without the compressor load that comes with a full self-contained unit.
Key Features of the CTM EV-12 Evaporator (115V)
This evaporator shares CTM’s standard split-system design across its lineup, built for durability and straightforward installation on existing marine A/C plumbing. The following features come standard on every EV-12 unit regardless of voltage.
- Direct drop-in replacement for the Dometic TVE evaporator
- 350 CFM blower airflow suited for mid-sized cabin spaces
- Reusable air filter removes, washes, and reinstalls without replacement
- Vibration isolation bases under the blower reduce noise transfer into the cabin
- Stainless steel frame base resists corrosion in harsh marine environments
CTM EV-12 Technical Specifications (115V)
These figures come from CTM’s official spec sheet for the 115V configuration. Confirm ducting size and amperage draw against your existing installation before ordering, especially if you’re replacing a Dometic or Cruisair unit with different connection dimensions.
- Capacity: 12,000 BTU
- Voltage: 100-120V
- Cycle: 50-60 Hz
- Refrigerant: R410A
- Blower Airflow: 350 CFM
- Blower Speed: 1,200 RPM
- Input Rotor Amps: 1.5 A
- Locked Rotor Amps: 1.8 A
- Fuse Max: 3 A
- Blower Duct Size: 5″
- Dimensions (W x D x H): 16.1″ x 10.7″ x 13.4″
- Net Weight: 19.84 lbs
Why Choose the CTM EV-12 (115V)
If you’re replacing a Dometic TVE, this evaporator matches its dimensions and waterline connections closely enough that installation generally shouldn’t require significant modification, and it’s backed by CTM’s standard 2-year warranty against material and workmanship defects. Current draw here is minor compared to the matching condenser, since only the blower motor pulls power rather than the compressor.
What to Know Before Installing
- Requires a matching condenser purchased separately — this listing is the evaporator only
- 5″ blower duct connects to your cabin’s ductwork
- If replacing a Cruisair TV12 unit, this evaporator will need pairing with an R410A-compatible condenser since TV12 systems use R22/R417A
- The reusable air filter should be cleaned periodically as part of routine maintenance

CTM EV-12 Marine Evaporator FAQ
What are the electrical requirements for EV-12?
CTM EV-12 operates safely on a 115V power connection. This domestic single-phase air handler setup draws minimal active running current, enabling boaters to operate localized stateroom ventilation smoothly off standard dock shore power utility grids or portable generator panels without overtaxing smaller vessel distribution breakers.
What airflow volume does this system deliver?
CTM EV-12 generates an airflow volume of 350 CFM. The integrated multi-speed centrifugal blower fan moves air efficiently through restricted compartment layouts to guarantee rapid interior dehumidification and cooling while maintaining a quiet acoustic profile that prevents sleep disruption during overnight anchorages.
Which vessels fit the CTM EV-12?
CTM EV-12 is designed for mid-sized master staterooms and forward V-berths. It serves as an optimal companion for sailboats and motor yachts from thirty to thirty-eight feet, matching seamlessly with a remote CX condenser unit to preserve valuable interior headroom and walking clearances onboard.
