In tasteless with so many questions the answer starts with..."it depends". It depends mostly upon where you live because the first of two key issues is the ambient climatic characteristic of your garage.
If your home is in the one of the warmer parts of the world you have more options to choose from but if there are months of the year when your stable may be 60°F/16°C or lower for weeks or months at a time you will need a dehumidifier capable of sufficient low climatic characteristic operation.
DEHUMIDIFIER
A straightforward room dehumidifier will be sufficient but, if it is a refrigerant type it must have an active defrost feature. An active defrost system, often referred to as "hot gas defrost", stops the compressor and redirects warm air over the cold coil to melt the accumulated ice. This swiftly removes the problem, the compressor restarts and your dehumidifier is back in business.
Few room dehumidifiers have this feature. In its place they have a passive defrost feature ordinarily referred to as "auto-defrost". What happens when ice forms is that the compressor stops, the fan keeps running and the ice is melted by the incoming air.
The lower the ambient climatic characteristic the longer it takes for the ice to melt. In low temperatures the dehumidifier will be defrosting for more time than it is dehumidifying.
Dehumidifiers with "auto-defrost" are often rated for performance in temperatures as low as 41°F/5°C but all this de facto means is that the dehumidifier will not be damaged at such low temperatures. The sad truth is they are scarcely sufficient when it gets so cold.
The second key issue is the level of relative humidity you need to maintain. To safe your car, your tools, tool and anything else made with steel from corrosion it is leading to keep relative humidity no higher than 55%, preferably 50%.
Refrigerant dehumidifiers begin to struggle when relative humidity falls below 50%. A room dehumidifier of cheap potential will contend 50% Rh but it will do so more reliably if it has a petite more power than the area of your stable might suggest is needed. It will cost more to buy a slightly larger dehumidifier but it will take off more moisture per Dollar, or Pound, of power consumed, and should run for fewer hours per day, so may be less high-priced in the longer term.
The ideal explication is a desiccant dehumidifier. What we are talking about here is a unit that looks like a refrigerant dehumidifier, sounds like a refrigerant dehumidifier and has a fan, but removes moisture by capturing personel water molecules on a desiccant (water adsorbing) wheel or rotor. That "d" in adsorbing is not a typo. The word describes a chemical process, clear from absorption which is a physical action typified by a parasite soaking up water. This type of dehumidifier is not to be confused with containers of silica gel, without enchanting parts, which take off small amounts of water and are best noteworthy to closets and drawers.
Because refrigeration is not complex in the process this type of dehumidifier will operate quite happily down to 33°F/1°C and will favorably sell out relative humidity below 50%.
In the Uk both types of dehumidifier are easily available. The Mitsubishi Mje16Vx is an exquisite refrigerant dehumidifier with hot gas defrost and the ideal refrigerant dehumidifier for a garage. If a desiccant dehumidifier is beloved there are several to choose from, including the extremely regarded Meaco Dd122Fw-Mk4.
In the Usa the situation is not so good. Desiccant units are very hard to find and are not ready from the major retailers. Refrigerant dehumidifiers with hot gas defrost are almost equally rare although one or two suppliers are listing the Mitsubishi unit, but at the ridiculous price of nearly 0, more than twice the price of those on sale in the Uk.
For 0 or a petite less a small market dehumidifier, such as the Ebac Cd30, may be purchased. A unit such as this provides hot gas defrost, is rated down to 33°F/1°C and offers the greater reliability of a unit built for demanding market applications. Small desiccant dehumidifiers built for market use are also ready but are much more expensive.
This kind of cost may not even be determined by most habitancy but if you have a superior car in storage in a stable you may feel it is worth the investment.
One final point; if the contents of your stable are sufficiently high-priced to elucidate the cost of a dehumidifier it may be advisable to invest a petite more to purchase a good potential hygrometer, a gadget for measuring relative humidity. The humidistats on dehumidifiers, more particularly room dehumidifiers, are not all the time accurately calibrated. Good to be safe than sorry.
