Measures to prevent poor performance of the DWT-1-14 axial flow roof fan:
When space or other factors want When the connection between the outlet and the inlet of the fan is required to be poorly arranged, an appropriate margin must be considered in the design calculation. When designing connections between fan systems, a uniform and straight airflow condition should be provided at the exit and inlet of the fan as much as possible, leaving sufficient margin for the effects of system and fan performance on all accessories and accessory equipment. Which effective field test technology is used for a certain system, attention should be paid to the accuracy and condition of the measurement.
System additional resistance
Poor system performance due to some of the undesirable airflow conditions described above. Assuming that the pressure loss of the system has been determined, the appropriate fan is selected for this point of operation. However, there is no margin left in the system connection for the performance of the fan. In order to compensate for this “system-added resistanceâ€, it is necessary to add a “system-added resistance coefficient†to the calculated system pressure loss to determine the actual system curve. The system's additional drag coefficient for any given Bry is speed-dependent, so It will vary within the entire airflow flow of the fan.

UNI-SEC Soap Dispenser:
Wall-mounted liquid soap dispenser, made of ABS,can be manually operated by means of a handle, or can be automatic.It can be used for liquid soap, foaming soap ,other liquids such as hand sanitizers, shampoos, or hand lotions. The design of a touchless soap dispenser is generally determined by whether the soap comes in liquid, powder, or foam form.Automatic dispensers are often battery-powered. The touch-free design dispenses the liquid when a sensor detects motion under the nozzle.
UNI-SEC`s sanitizer dispenser automatic are suited for commercial washrooms, hospitality, health and public amenities.
