Dometic Turbo Unit (DTU) vs. EnviroComfort Unit (ECD)

| Updated: | Published: |

Being Dometic dealers, we know well both the Dometic Turbo DTU and Dometic Envirocomfort ECD – the company’s two most popular self-contained marine air conditioners – quite well. They both come in cooling capacities from 6,000 to 16,000 BTUs, but there are a few key differences. (note: for the Dometic DTG vs CTM CT Unit, see here).

We’re highlighting the pros and cons of both units below:

Dometic Turbo DTU Unit

Powerful, Quiet & Compact With No Drain Pan Worries

The Dometic Turbo DTU series completely revolutionized self-contained boat air conditioning with patented innovations in marine air conditioning system design, winning the IBEX Innovation Award. The rust-free molded composite drain pan has three drains for the rapid removal of condensate water. The drain pan has a small footprint for installation flexibility. A vibration-isolation mounting system results in significantly quieter, virtually vibration-free performance. The enclosed blower motor eliminates overhang for reduced depth.

The Dometic Turbo DTU is available in 6,000, 8,000, 10,000, 12,000 and 16,000 BTU/hr, with the 16,000 BTU Dometic DTU16 being the top seller.

These new and updated versions of the self contained unit also have the dual capability of heating and cooling. Through its reversing valve, the unit can be used as a heater and air conditioner.

Dometic Turbo DTU PROS

  • Turbo blower has 30% more capacity
  • Compact, lightweight
  • Composite drain pan will not rust
  • Optional sound cover further reduces compressor noise by up to 50%
  • More modern design
  • Reverse cycle = cooling and heating
  • Slightly further rotation allowed on blower
  • New “U-Board” Universal control Board

Dometic Turbo DTU

  • Higher price point
  • Doesn’t come with control / display or cable because it’s intended to be replacement for previous Dometic models (Stowaway Turbo STX, Vector Turbo Unit VTD)

*Dometic Turbo DTU Units are direct replacements for all VT and ST units. All units include temperature sensor. Display cable not included.

 

Dometic EnviroComfort – Dometic ECD

Dometic ECD

Enjoy Year-Round Comfort with EnviroComfort – Dometic ECD

Dometic’s EnviroComfort Units (ECDs) are available in 6,000, 10,000, and 16,000 BTU/hr cooling and reverse-cycle heating capacities, so you can size the system to suit your boat for ultimate comfort in a range of climates.

All units have blowers with internal motors for a more compact installation footprint. The blower can be rotated to a horizontal or vertical position for greater installation flexibility. ECD units are built on an easy-to-plumb stainless-steel drain pan, and the pre-installed return-air filter is removable for cleaning.

Dometic ECD units are operated by a compact digital control/display (included) that features a bright green LED and large buttons. For added installation convenience, the plastic electrical box can be mounted remotely.

ECD kits are ideal for replacing an existing air conditioning system or for a new air conditioning installation. The Retrofit Kit includes the ECD self-contained air conditioning unit and digital control with bezel and is intended to replace an older self-contained air conditioner of comparable capacity. The ECD6K will replace a 5,000 to 7,000 BTU/hr unit; the ECD10K will replace an 8,000 to 11,000 BTU/hr unit, and the ECD16K will replace a 12,000 to 16,000 BTU/hr unit.

Dometic ECD PROS

  • More economic price point
  • High-velocity blower provides powerful cooling
  • Compact, lightweight design
  • Control / display and cables included
  • New “U-Board” Universal control Board

Dometic ECD CONS

  • Pans are stainless but not stainfree – therefore some rusting may occur over time
  • No sound cover option

Good Replacement Option for Dometic DTU or ECD Units – CTM CT Units

The CT-Unit from CTM is a new unit in the market that works as a direct replacement for the Dometic DTU or Dometic ECD. The CT Unit offers several advantages that the ECD nor the DTU offer. It comes standard with corrosion-resistant titanium condensing coils and ABS drain pan, high-velocity blower, universal control board (compatible with most Dometic / Cruisair / Marine Air controls), quiet compressor, compact design, and more. 

The CTM Units come in either 10,000 or 16,000 BTU’s, 115V and 230V. CTM is offering these units at a competitive price, starting at just $1,699.00. If you want to know more about the CT Units, see here: CTM CT Marine Air Conditioners

    1. Hello Manuel, the CTM CT-16 is an exact replacement, as is the DTU16. The CTM is compatible with the majority of Dometic’s thermostats, but double check with our sales guys just to ensure compatibility.
