All of the mentioned brands are very expensive and have high operating cost. There is new, smaller, more efficeint equipment available.

Dectron makes a nice product, agreed.

A couple of things that I don't like about Dectron, although it is a good unit is:
1) In the ones I have services/set-up the compressor is located in the air circuit which is not a good thing should the refrigerant burn and exit the lines; and that location adds to compressor noise.
2)They seem to be set-up more towards dehumidification as a primary function and pool water heating as a secondary function. True that the microprocessor can be set to supply pool water heat as the primary but it just doesn't supply heat in the same quanity as other makes I have worked on.
3) The set up of the microprocessor head can be quite complicated requiring totaling the types of applications for that particular job. Should a new tech not know the accessories or system specs, it's can be time consuming to trace out or figure out the system.
4) They use a damper motor and a sensor to open/close the dehumidification by-pass damper for freeze control. That system and trouble shooting it can be complicated.
5) The room air sensor is actually located inside the return air of the unit and not in the microprocessor head itself. On a long run with heat gain/loss I have had to compensate.
6) I have had some problems with the air flow sensor, which is also located in the RA, in giving off false restricted air flow alarms so, usually, I reduce the air flow amount below 40% to help eliminate the alarms."The American Republic will endure until the day Congress discovers it can bribe the public with the public's own money.

Pool Evaporation Calc
You need to provide a few more pieces of information to calculate the pool evaporation rate. There are 4 items missing from your initial description: 1. Pool water temperature desired, 2. Air temperature desired, 3. type of pool (for activity factor ie residential, hotel, condo, therapy) and 4. number of hours of activity in a day-- more waves and splashing, more evaporation.

For indoor pools with proper vapor barriers in the walls and ceiling, DX dehumidification with the ability to reject the aborbed energy back into the pool water or the air simultaneously. I reccomend Dectron because they have been in the business for over 30 years, they are built to last and they give you total control over the humidity and temperature in the space.
As far as sizing the unit for your load, there are many factors involved including desired pool and air temperatures, your location and the dimensions of the pool and enclosure.
Your best off to call your local dehumidifer representative. As a starter though, Dectron has put together a great design guide available on their website by clicking on the customer service tab.

I like DessertAir for the most part. However the ones we have around here are all suspended from ceiling in tiny rooms so I hate trying to service them. Also have had problem with remote air cooled condensers leaking at tubesheet. One system is on its 3rd warranty replacement, they are Heatcraft condensers though. Work well other then that.

In my area in Ottawa Canada it's all about Dectron. They have the market and it is a huge part of my work. I have been working on them for 25 years now and have nothing but good to say about them. They run about $$$ installed.

I've only had experience with the Desert Air equipment...after I fixed it from a previous company's quality job...it worked great. Customer was very happy. It was for an indoor spa.
