Super Maramu Saloon Air Conditioner


Bill Kinney
 

It might be time for us to replace our saloon air conditioner.    This is a difficult fitment.  It needs to be no more than 12" (305 mm) high, which takes a lot of units out of the running.  Mermaid in Florida used to make one, but they have recently gone under.  

Our current unit is 9,000 BTU and that is adequate--just--for the application.  I'd like to have a 10,000 if one can be had that will possibly fit.  And while I am dreaming, it should also operate on 50 or 60 Hz, and be a reverse cycle to heat as well as cool.

It looks like Westabo makes an 8000 BTU model (The S8) that checks all the boxes.  Has anybody found something else they like for this application? Or maybe a clever mounting trick that gains an extra centimeter or two of vertical space?

The Webasto unit is a bit too cheaply build. Not a bad unit but the fan is made from mild steel and tends to corrode because of the condensation. I have one in the guest area it still works after 4 years.
My other 2 units are from Frigomar (www.frigomar.com). Very nice units. I have a model SCU16VFD (16k BTU) in the main cabin and a SCU10VFD (10k BTU) in the rear cabin. The latter is wxhxd 433x282x260. The bigger unit is 500x336x290.
These are inverter units using a variable speed compressor with no significant start-up current to frustrate inverters. Also they become very quiet when the temperature level is achieved and they only need to maintain this.
In the USA they are sold by Titan  https://titanmarineair.com/product/scu10vfd-a-self-contained-unit/

Hi Bill,

Climma make a 9000 BTU reverse cycle unit that would probably fit in that space....

We replaced the aft cabin unit with a Mermaid RV unit some years ago...very efficient, but also VERY noisy....interesting that they have "gone under"...maybe it was the noise!

Good luck !

Cheers

Hi Bill,. 
I replaced the fwd unit with a slightly smaller (6,000btu?) Unit with reverse cycle heating from MarinAire, I believe from Fort Lauderdale.

Fitment was easy (it's smaller) except the hoses ended up being on the far side and needed replacing.

The 6,000btu unit was much stronger than the dated 9,000btu Climma that came out. I was very pleased.

I am certain the 6,000btu unit would fit easily in the salon space, but since that's a whole lot more area a 9,000btu unit would be a stronger performer.  To that, I can't attest about fitment.

Now, I only had the unit for about a year before I sold Adagio, but I was impressed with how much better it performed in the V-berth.  Being a reverse cycle heater, it was slower.tonwarm.up but still did a nice job for us.  The remote was nice too ;).

Arno,  thanks!  


The frigomar units hadn’t come up on my searching.  The 10000 BTU model looks promising, it is the most compact unit I have seen of that capacity.

 I am guessing the 54 has quite a bit more space available if you managed to fit a SCU16VFD in the saloon.  The drawings I see have it’s height at 336mm, significantly higher than the space I have available.

Gary,

Thanks for the help!

We are well familiar with MarineAire, we have one of their units in the aft cabin we are very happy with.  A great company to deal with, in our experience, but unfortunately, their 9000 BTU units are just a bit too big in the vertical dimension to fit in our saloon space.

I installed the Vitrifrigo 7000btu in the front cabin. It was a simple plug and play. There 12000btu unit is slightly higher but you can remove the foam of the original installation.

Hi Bill,
    I replaced the original "split" air conditioner with a new package unit eliminating the compressor in the ER. It fits where the old evaporator sat just fine.  Let me look up the brand.

Hi Bill,  sorry for delayed response.  Just got my hands on the receipt.  See attached.   
Like someone else said pull out all the old hvac mounting gear and the unit should drop in.  

I got rid of all the old hvac gear and rerouted cooling water behind the oven to the new unit.  Hose fit in same penetration as old freon lines so no drilling.
