Humans tend to make mis­takes. One unfor­tu­nate mis­take when choos­ing an air cur­tain can remind you of itself in the future with drafts, tem­per­a­ture imbal­ance, exces­sive noise and irra­tional ener­gy costs. It turns out that when choos­ing a ther­mal cur­tain, the lion’s share of poten­tial buy­ers step on the same rake. To avoid this, all you need to do is read this text.

1. Ignor­ing the indi­ca­tor of the height of the open­ing

The first place in the list is occu­pied by an incor­rect cal­cu­la­tion of the length of the open­ing (or height, if the instal­la­tion is sup­posed to be ver­ti­cal). In this case, cold air from the street can enter the room from the left or right (from above or below, respec­tive­ly). To avoid this, choose a cur­tain equal to the width of the open­ing or with a mar­gin — a lit­tle wider. The typ­i­cal length of the air cur­tain unit is 0.8 to 2 m.aboutgreater width, the cur­tains are mount­ed in a row at a min­i­mum dis­tance from each oth­er. The clos­er the cur­tains are, the high­er the final effi­cien­cy of the ther­mal equip­ment will be.

3. Wrong choice of ener­gy source

Wrong choice of equip­ment accord­ing to the source of ener­gy con­sumed. Some­times, in order to save ener­gy costs, buy­ers choose a water air cur­tain, or vice ver­sa, based on ease of instal­la­tion, they choose an elec­tric one. Remem­ber that equip­ment can con­sume up to 48 kW, and your elec­tri­cal net­work must be designed for such loads. In the case of choos­ing a water cur­tain, con­sid­er the avail­abil­i­ty of water and its pres­sure.

5. Invalid advanced options

Last but not least on our list are errors relat­ed to advanced options. The noise lev­el from the equip­ment can be crit­i­cal for cater­ing estab­lish­ments. Spe­cial hous­ing and parts pro­tec­tion may be required for air cur­tains in places with aggres­sive envi­ron­ment, such as car wash­es, etc.

2. Per­for­mance mis­match

Wrong choice of equip­ment for per­for­mance. It is impor­tant to under­stand that the effi­cien­cy of the air-ther­mal cur­tain is not deter­mined by the tem­per­a­ture of the air blown out by the device, but by the strength and speed of the air flow. This is called cur­tain per­for­mance. There­fore, the high­er the door­way, the more pro­duc­tive the equip­ment is need­ed.

4. Wrong cal­cu­la­tion of pow­er

Unrea­son­able choice of equip­ment pow­er. Pow­er is a mea­sure of the tem­per­a­ture of the air blown out by the fan. The main thing in deter­min­ing the required pow­er is to ade­quate­ly assess the char­ac­ter­is­tics of the door­way, the fre­quen­cy of open­ing doors or gates, the pres­ence of indoor heat­ing, etc. Remem­ber that even the most pow­er­ful air cur­tain blows warm, but not hot air, so you should not choose a cur­tain for the pur­pose of heat­ing the room.

A few words about reli­a­bil­i­ty and repair

Like any oth­er equip­ment, air cur­tains can fail if used incor­rect­ly. A mal­func­tion requir­ing repair may man­i­fest itself in a decrease in the pow­er of the equip­ment, the appear­ance of extra­ne­ous noise and vibra­tion on the case, a decrease in the speed of the air flow and a decrease in its tem­per­a­ture, the appear­ance of streaks, etc. This may be due to a break­down of the main com­po­nents and assem­blies of the air cur­tain — a fan and a heat exchang­er, as well as indi­vid­ual heat­ing ele­ments or equip­ment con­trol sys­tems.

Many factors influence the correct choice of an air curtain: from the parameters of the room and the doorway to the available power sources, therefore, for the most suitable and efficient equipment for your conditions, it is better to turn to professionals who will select the best solution.

Many fac­tors influ­ence the cor­rect choice of an air cur­tain: from the para­me­ters of the room and the door­way to the avail­able pow­er sources, there­fore, for the most suit­able and effi­cient equip­ment for your con­di­tions, it is bet­ter to turn to pro­fes­sion­als who will select the best solu­tion.

In some cas­es, the repair of ther­mal cur­tains con­sists in replac­ing ele­ments. How­ev­er, only a mas­ter can make a diag­no­sis and find the true cause, so you should not dis­as­sem­ble and repair the device your­self, espe­cial­ly if it is under war­ran­ty.

To pre­vent break­downs of ther­mal cur­tains, main­te­nance should be car­ried out reg­u­lar­ly. Before start­ing, inspect the machine to avoid the ingress of dirt and for­eign objects.

Water qual­i­ty is impor­tant for a water ther­mal cur­tain. Before enter­ing the water cur­tain heat exchang­er there is a fil­ter that col­lects all the dirt. In order for the equip­ment to serve for a long time, it must be cleaned reg­u­lar­ly.

An impor­tant role is played by the con­di­tion of the wiring — pow­er cables, switch­es, and con­trol lines that need to be inspect­ed peri­od­i­cal­ly.

Top 3 main caus­es of air cur­tain break­downs:

  • the air cur­tain is incor­rect­ly select­ed, the ther­mal pow­er is illit­er­ate­ly cal­cu­lat­ed, due to which the heat exchang­er failed (this is espe­cial­ly true for water cur­tains);

  • incor­rect instal­la­tion;

  • equip­ment is out of ser­vice.

If air curtains are stale in warehouses, then these are almost always models of the “mini” and “midi” categories.  They are purchased by dealers in bulk at the beginning of the season and, if demand is lower than expected (due to, for example, weather conditions), they remain unclaimed.  Models from the

If air cur­tains are stale in ware­hous­es, then these are almost always mod­els of the “mini” and “midi” cat­e­gories. They are pur­chased by deal­ers in bulk at the begin­ning of the sea­son and, if demand is low­er than expect­ed (due to, for exam­ple, weath­er con­di­tions), they remain unclaimed. Mod­els from the “maxi” and “super­maxi” cat­e­gories in most cas­es are intend­ed for end cus­tomers and for real projects, so they are less like­ly to end up in sur­plus.
