Cleaning of registers of an air handling unit (HVAC) in a difficult to access area without compressed air and water supply

Practical solution example for operating problems due to very heavy loading of a heat recovery coil

In this case, cleaning with compressed air was not sufficient to remove the clogged dirt from the
register. The use of a high-pressure water process was also not possible due to the sensitive lamellas and the quantities of dirty water produced. This is where the JetBoy can show its strength of low water consumption to the fullest. JetBoy requires 0.4 m³ of compressed air at 6 bar and 0.1 l of water per minute.

The cleaning in detail

The heavy loading was only evident from the impermissibly high differential pressure. The surfaces looked relatively clean. During the first cleaning pass, fibers and dust were already thrown out of the register. At the end of the cleaning, the discharged contaminants could be seen on the floor behind the exchanger. Lances are available to extend the reach for hard-to-reach areas in HVAC.

The remaining registers are protected by an F7 filter and showed only a normal degree of contamination. Here, the coil surface was cleaned with only one pass. By cleaning the registers, a normal differential pressure of the HVAC could be achieved again.

mycon offers all prospective customers for JetBoy and JetBoy SP a "test month" for rent. If the device is subsequently purchased, the rental fee for the test month will be deducted in full from the purchase price.

JetBoy and JetBoy SP are also available on a rental basis for almost any desired period (minimum rental period 1 week).

mycon delivers the equipment in special transport boxes. Rented equipment can thus be returned safely and without any problems.
