The Meaco DD122FW MK4 is a low temperature dehumidifier ideal for use as a Boat Dehumidifier or Garage Dehumidifier. It uses desiccant technology to remove water from the air and does not ice up in cold conditions.

It is capable of continuous drainage so there is no need to empty a bucket once or twice a day and it has auto-restart which means it will switch itself back on if it is stopped by an interruption in the power supply.

A dehumidifier that can work effectively at temperatures just a little above freezing and can run for weeks without attention from the owner is the perfect way to control humidity in a boat moored 40 miles from home or a garage housing that prized vintage car that you only take for a spin on dry, sunny days.

Years ago, when most of you were young and I was just a little less old, the word "dehumidifier" identified an appliance with a compressor, a fan, condenser and evaporator coils. We didn't need to put the word "refrigerant" in front because all

(home) dehumidifiers were refrigerant dehumidifiers.

Despite the name a refrigerant dehumidifier hates the cold. When it gets a bit chilly, below about 18C/65F, ice forms on the evaporator coil and the machine has to stop from time to time to defrost. The fan keeps running and the flow of ambient air

melts the ice but the colder it gets the longer it takes to thaw.

It's pretty obvious that the cooler the air the quicker ice will form and the longer it will take to melt. Dehumidification becomes progressively less until the appliance resembles nothing but an overweight fan.

In any space where the temperature may be 10C/50F or less for long periods a refrigerant dehumidifier is pretty near useless.

A few dehumidifiers are available with an active defrost system which directs warmed air over the coils to melt the ice more quickly but they are more expensive, although they are effective in cool temperatures.

While our dehumidifiers shivered in summer temperatures, deep in the world of industry and commerce lurked another type of dehumidifier, the "Desiccant Dehumidifier". If you have ever watched one of those TV shows where a submarine goes two miles down in the Marianas Trench and films strange marine monsters that never see daylight and glow in the dark you'll have some idea what kind of environment is inhabited by the desiccant dehumidifier. "Cold and dry" doesn't do it justice. Imagine walking across the Sahara in Arctic temperatures and you have it.

"This is the kind of dehumidifier I need on my boat", you cry. Yes it is, but until recently you would have had to have paid thousands to own one. In recent years desiccant technology has been made affordable for ordinary people and is now available in home dehumidifiers.

Because they are designed for use in the home the monsters have been tamed and house trained. They will not work in sub-zero temperatures like their "wild" cousins but they will keep going to just a degree or two above freezing.

Now you have the kind of dehumidifier you need on your boat, in your garage, tool shed, garden office, unheated conservatory, caravan or any other modestly sized enclosed place that gets cold; at least here in the UK it does.

We have the dehumidifying technology but boats and many others among these cold places do not get visited every day so who is going to empty the bucket? What happens if the power goes down?

Add continuous drainage, auto restart, electronic controls, a timer and a humidistat, all wrapped up in a compact, light-weight package and you have an ideal dehumidifier for your boat, your garage or any of those other cold places you can't get to on a daily basis.

The Meaco DD122FW MK4 Dehumidifier is not the only unit of this kind but it is an appliance very positively reviewd by consumers, with a proven track record, from a reputable and well known supplier.

Whether you want a Boat Dehumidifier, a Garage Dehumidifier or a dehumidifier for your out-door privy the Meaco DD122FW MK4 is one of the best low temperature dehumidifiers for unattended use you could choose.
