Built to work for decades


The ultimate humidifer for cigar cabinets.

MCT L is designed to ensure uniform air humidity in 2m high cabinets without any additional device, water tank or fan.

At a 2m vertical height difference both gravity and temperature has effect on humidity dispersion, but MCT L was engineered to handle every physical impacts. The 3 layers of acriliy gel pack stores 2l of water, and lasts for 5-6 month until refill. You mount conveniently the elegant controller magnetically to your eyes height, and so it also measures humidity physically at a right place.

Special MCT Features

The smartest electronics control

Humidity is measured by the sensor built in the control panel

Uneven humidification is among the most common problems that could decrease the quality of your cigars. In many cases, different humidity levels in humidors are due to an improper measurement mechanism. Sensors are generally directly attached to the humidifier, and measure humidity levels on the side of the machine. The upper region of your cabinet therefore hardly ever gets enough moisture. In every MCT cabinet humidifier (M, L, XL) therefore the sensor is separate from the humidifier and is placed in the control panel. This way, humidity can be sensed at any place in your humidor, depending on where you place the control panel.

Premium quality components for most accurate measurement

Reliable and accurate measurement is a key factor of humidification. We rely only on the best, precision capacitive Swiss sensor from a world leading sensor manufacturer. The large, easily readable LCD comes from Germany, the computing unit from the USA.

Two stage menu system for the safety of your cigars

To avoid accidental or unwanted changes in the settings, a two stage menu system is applied. In the first stage you can set the humidity, while in the second, hidden stage, you can fine tune every function related to operation and calibration.

Menu functions
  1. set humidity – default 70% – by 0.1 %RH steps
  2. calibrate humidity – default 0.0% – by 0.1%RH steps
  3. humidity drop – fan on gap – default 0.5% – by 0.1%RH steps
  4. calibrate temperature – default 0.0% – by 0.1 degrees
  5. sensing averaging default 3 – by 1 measurements
  6. fan on 20 – by seconds
  7. fan off 10 – by seconds
  8. fan speed 80% – by 1% -continuously
  9. door open 0 – by 1 second

Enhanced humidification performance

Innovative gel pack technology

Instead of pouring water into the machine MCT humidifiers contain acrylic-polymer gel packs to ensure humidification. The patent pending technology was invented by MCT, to dramatically increase efficiency and lifespan. The material is 100% inorganic, therefore mould and bacteria free acrylic-polymer. Our patent pending solution is to put the acrylic crystals into our special net, that once thrown into water swells up to form the cylinders of a pack. The MCT gel pack can be used for years, without replacing it!

Extremely increased humidification surface

In MCT L, three layers of gel packs lying on positioning grids – 3 cylinders each – are responsible for the increased humidification performance. MCT L has 6 times bigger humidification surface than a usual, tank-type device filled with the same amount of gel.

Powerful air ventilation

To ensure efficient operation, air ventilation system is indispensable in all MCT humidifiers. The other important function of cylindrical shaped gel packs is that the air can stream through fast, there is no barrier to slow it down. Thanks to the huge humidifier surface even the rapidly flowing air picks up a great value of moisture.

Noiseless operation

Premium quality silent fans and minimalized air noise make you MCT whisper quiet.

Uniform air humidity

Guidable humid air ventilation

Each MCT has air outlet holes both on its top and the bottom which you can block with the supplied accessory plugs, depending on which direction you want the humidified air to be blown. Out of the 7 wholes MCT L has, 4  should be used.

Standalone operation

MCT was created to work properly without any additional fans, water tanks, etc. The unique MCT feature is that if you place it vertically in the middle and push it to the back wall of a cabinet, you can have the air blown up and down ensuring a real uniform humidity! No second water tank, no additional fan, wires are needed.

Air duct, double back walls

If you own a humidor that has an air duct or double walls, MCT is the appropriate humidifier for you.
All MCT models are designed to work excellently with any kind of air guiding implementation.

Custom settings, adjusted to your humidor

Periodic ventilation

If you experience that the humidity level is always above the set value, periodic ventilation may be the solution for your problem.

Fan speed control

It is possible to regulate the intensity of the humidification by continuously adjusting the fan speed. MCT models are powerful, if you place them into small humidors, often slower speed can yield the desired outcome.

Door open function eliminating undesired over humidification

When a humidor lid or door is open, the inside humidity automatically decreases, so the sensor turns on the machine. In many cases, for example when the humidor is packed full of cigars, excessive moisture is generated inside, keeping the humidity constantly higher than the set value. The Door open function does not start the machine while the door is open eliminating the undesired over humidification.

Exquisite materials and design

Spanish cedar control panel

Every MCT control panel is a masterpiece, made of one piece solid Spanish cedar wooden block, CNC forged and laser cut, hand polished. It was designed to match in style even the most exclusive humidors. The buttons are custom made from one piece of aluminium. The control panel can be mounted magnetically by the supplied accessory.

Aluminium-Magnesium construction

The body of each MCT humidifier is made of a 100% water resistant light metal, Aluminium-Magnesium alloy, to last for a lifetime. They are painted to maduro brown, cream gold and cedar beige to match the interior of a humidor.

Easy to service

Reliable machine that is easy to service

Our philosophy is to produce extremely reliable machines that work for decades. Using the best quality parts secures a rock-stable operation. Each MCT model is tested thoroughly before packaging. The body is made of metal. The control panel is detachable, in case of any defects it can be easily and cost-effectively repaired or replaced during the 3-year warranty, and beyond.

To get the best result we recommend two ways to use MCT L in a humidor cabinet.


1. As a standalone machine:

Place MCT L in the middle, to the backwall, plug the upper right 3 holes letting the air blown out from the left top and bottom 2-2 holes. To work as precise as possible MCT L is designed to blow a certain amount more air upwards to equalise gravitational effects.

Using with an air duct or in a double back wall humidor

Using an air duct has its benefits. Always ask your humidor cabinet manufacturer, whether they have the know-how to use an air duct. Maklary Humidors uses all MCT models with specially constructed air ducts.
