Dometic DTG vs Webasto FCF Platinum vs CTM CT Unit – Comparison

| Updated: | Published: |

CTM has introduced their all new CT Self-Contained Marine Air Conditioners to the market, and a question we often get here is how do the CTM CT Units compare to Dometic’s DTG (previously known as Dometic DTU) Units and Webasto’s FCF Platinum series, two of the most popular self-contained marine air conditioners available.

We’ve put together an analysis comparing different aspects of all three units – the Dometic DTG, CTM CT Unit and Webasto FCF Platinum units.

 

Size Comparison between Dometic DTG, CTM CT and Webasto FCF Platinum Marine Air Conditioning Units

Taking Dometic’s DTG16 (16,000 BTUs), Webasto’s FCF16 Platinum Series (16,000 BTUs) and comparing it to CTM’s CT-16 (16,000 BTUs) to compare sizes, all three units have a similar footprint, with the Webasto FCF16 a decent bit larger in each dimension than the other two units, and the CTM significantly smaller in width than the rest. The CTM and Dometic weigh approximately the same, and the Webasto FCF Platinum is a good bit heavier. Here are the dimensions and weights of each:

Dometic DTG16 vs Webasto FCF16 vs CTM CT16 Unit Size Comparison
Dometic DTG16 Webasto FCF16 CTM CT16
Width (inches) 21.4 24.4 20
Depth (inches) 13 13.5 13.5
Height (inches) 13.5 13.1 14
Weight (lbs) 57 77.5 57

Comparison of Materials and Design Features

All three units — the Dometic DTG, Webasto FCF Platinum Series and the CTM CT — have durable construction, and are ready for marine-use. The DTG brings a rust-free composite drain pan, while the CTM and Webasto units bring stainless steel structural pans (CTM with ABS tray; used in heavy industrial applications, ABS is extremely resistant to corrosion, weathering and erosion, as well as aqueous acids, alkalis, alcohols and oils).

Webasto FCF Platinum units are epoxy-painted for corrosion protection, while the CTM CT Unit uses corrosion-resistant titanium coils. DTG units use copper coils which are prone to corrosion. As to the benefits of using titanium coils:

“Titanium resists corrosion by seawater to temperatures as high as 500°F (260°C). Titanium tubing, exposed for 16 years to polluted seawater in a surface condenser, was slightly discolored but showed no evidence of corrosion.(8) Titanium has provided over thirty years of trouble-free seawater service for the chemical, oil refining and desalination industries. Exposure of titanium for many years to depths of over a mile below the ocean surface has not produced any measurable corrosion(9)”

Differences in Design and Cooling Efficiency

The CTM unit has an advantage over the other units in design and cooling-efficiency. On Dometic DTG and Webasto FCF Platinum units, air flows through the hot condensing coils before being cooled down by the condenser, and it is then blown out through the fan — which can cost efficiency. On the CTM CT Unit, room temperature is cooled by the condensing unit and the cool air is pushed through the blower’s tunnel without being affected by the heat of the coils, where it is then blown out by the fan, making the CTM unit more efficient on BTUs.

Energy Consumption Comparison Between the Dometic DTG, Webasto FCF Platinum and CTM CT Units

Both the DTG and CTM CT Units consume approximately the same amperage during startup and use, with the Webasto FCF Platinum Series consuming more upon startup, and a slightly wider range of current consumption cooling reported. All three are available in 115V and 230V voltages and 50/60 Hz frequencies. See comparisons of available energy-use info on the three 115V 16,000 BTU models below.
