China Fan Coil Unit Supplier No Middleman

Q: How to determine whether the cooling/heating capacity of fan coiler meets the demand?

UM: It is necessary to calculate the cooling/heating load (unit: KW) according to the room area, heat preservation performance, personnel density and usage, and refer to the design parameters provided by HVAC engineers for model selection. If the selection is too large, energy will be wasted, and if it is too small, it will not be able to meet the demand for temperature control.

Q: What is the difference between silent fan coiler and normal model?

UM: Silent type adopts low-noise fan, sound insulation material and optimized air duct design, the noise value is usually ≤35dB(UM), suitable for bedrooms, offices and other places with high requirements for quietness.

Q: How much space do I need to reserve for fan coiler installation?

UM: Space needs to be reserved according to the model size and installation method (ceiling, wall or vertical). For example, horizontal ceiling-mounted models usually require 300-500mm of space, and the location of the access port needs to be considered.

Q: Is it compatible with the existing central air-conditioning system?

UM: It is necessary to confirm whether the water system parameters (e.g. water temperature, water pressure) and interface size (e.g. DN20/DN25) are matched, and it is recommended to provide drawings of the original system or consult the technicians.

Q: How do fan coils need to be maintained on a daily basis?

UM: Regular cleaning of the filter (1~2 months/time), checking whether the condensate tray drainage is smooth, checking whether the motor and wind wheel are dusty every year, and recommending professional cleaning of the heat exchanger every 2~3 years.

Q: What are the possible causes of condensate leakage?

UM：Common reasons include: insufficient slope of the drain pipe, clogged condensate pan, condensation due to broken insulation, or excessive installation tilt. Adjustment or unclogging is required after troubleshooting.

Q: What should I do if the airflow becomes smaller or the noise increases?

UM：May be due to clogging of the filter, dust accumulation on the fan or bearing wear, need to clean or replace the parts. If the motor rattles, it is recommended to contact the after-sales service.
