An indus­tri­al dehu­mid­i­fi­er is a device that removes excess mois­ture from the air in large vol­umes. Wide­ly used in var­i­ous sec­tors of the nation­al econ­o­my.

There are many dif­fer­ent fac­tors to con­sid­er when choos­ing an indus­tri­al dehu­mid­i­fi­er:

  • per­for­mance:
  • air exchange;
  • incom­ing air flow pres­sure;
  • inlet and ambi­ent tem­per­a­ture;
  • dew point indi­ca­tor.

Addi­tion­al­ly, it is nec­es­sary to take into account the pres­sure loss of the air flow in the dehu­mid­i­fi­er itself, its fil­ter, and a num­ber of oth­er fea­tures (the vol­ume of the room, the num­ber of peo­ple work­ing in it, etc.).

When choos­ing an indus­tri­al dehu­mid­i­fi­er, its reli­a­bil­i­ty, ease of oper­a­tion and the cost of future main­te­nance are tak­en into account.

Equal­ly impor­tant is the pow­er con­sump­tion of the device. The high­er the per­for­mance, the more ener­gy is con­sumed. Here it is impor­tant to find the “gold­en” mid­dle ground — to pro­vide the desired air humid­i­ty at min­i­mal cost.

As you can see, the process of choos­ing an indus­tri­al dehu­mid­i­fi­er is quite com­pli­cat­ed, and only pro­fes­sion­als in their field can solve it. By the way, there are such spe­cial­ists in our com­pa­ny. They are always ready to give advice at a high pro­fes­sion­al lev­el. Con­tact.

What are the types of industrial dehumidifiers

A wide range of indus­tri­al dehu­mid­i­fiers is rep­re­sent­ed by var­i­ous types. The main dif­fer­ence is in the prin­ci­ple of oper­a­tion. The most com­mon are devices of con­den­sa­tion and adsorp­tion types. Less com­mon­ly used:

  • refrig­er­a­tion (or refrig­er­a­tion);
  • mem­brane;
  • del­i­quis­cent.

Con­den­sa­tion dry­ers work on the prin­ci­ple of mois­ture con­den­sa­tion. The tem­per­a­ture dif­fer­ence in the heat exchang­ers is obtained by com­press­ing the refrig­er­ant with a com­pres­sor.

Appli­ca­tion in a wide range — indus­tri­al premis­es, ware­hous­es, muse­ums, phar­ma­ceu­ti­cals, food indus­try and oth­er areas where increased require­ments are imposed on the mois­ture con­tent in the air.

Adsorp­tion dry­ers use the prin­ci­ple of extract­ing mois­ture from the air with an adsor­bent, for exam­ple, sil­i­ca gel.

Dehu­mid­i­fiers of this type are wide­ly used in explo­sive and flam­ma­ble pro­duc­tion.

Refrig­er­a­tion (refrig­er­a­tion) dry­ers in prin­ci­ple, their work is sim­i­lar to a con­ven­tion­al refrig­er­a­tion unit. Do not require large invest­ments in oper­a­tion and main­te­nance. The dis­ad­van­tage is that they have a low dew point.

Mem­brane and del­i­quis­cent devices have a nar­row scope. They work with­out exter­nal pow­er sources, the decrease in humid­i­ty is insignif­i­cant.

A care­ful study of the char­ac­ter­is­tics of var­i­ous types of air dry­ers will allow you to cor­rect­ly deter­mine the type of device you need. But at the same time, the word of experts should be final.

Note. Incor­rect selec­tion of dry­er type can lead to pro­duc­tion stop­page.

How a duct dehumidifier works

The duct dehu­mid­i­fi­er works on the prin­ci­ple of con­dens­ing the mois­ture con­tained in the air and then remov­ing it. At the same time, it heats the air leav­ing the room.

The work process is car­ried out as fol­lows. The refrig­er­ant com­pressed by the com­pres­sor (in most cas­es fre­on) pass­es into a liq­uid state. It heats up to a high tem­per­a­ture.

In a liq­uid state, it enters a hot heat exchang­er, where it par­tial­ly gives up its tem­per­a­ture. Fur­ther, pass­ing through the cap­il­lary tube, the refrig­er­ant turns into a gas. The process is accom­pa­nied by strong cool­ing. Cold gas enters the next heat exchang­er, sig­nif­i­cant­ly low­er­ing its tem­per­a­ture. The next “sta­tion” of the refrig­er­ant is the com­pres­sor. The closed cycle is repeat­ed.

At the same time, moist air pass­es through the cold heat exchang­er. As a result, the mois­ture con­tained in it con­dens­es on the walls of the evap­o­ra­tor and flows into a spe­cial mois­ture-col­lect­ing con­tain­er or drainage pipe.

Cooled, but already dry air is dri­ven by a fan through a hot heat exchang­er, where it takes its heat and then enters the room.

This removes excess mois­ture from the air and warms it up.

Thus, indus­tri­al dehu­mid­i­fiers dif­fer from house­hold dehu­mid­i­fiers in per­for­mance, increased size and weight.
