Note:
■ The above parameters are for standard units. However, EK can
customize these parameters to meet special requirements from
customers.
■ Working conditions for cooling under nominal return air flow: dry
bulb 27°C, wet bulb 19.5°C; working conditions for cooling under
nominal fresh air flow: dry bulb 34°C, wet bulb 28°C; water
temperature under nominal cooling capacity: inlet water 7°C, outlet
water 12°C.
■ Working conditions for heating under nominal return air flow: dry
bulb 21°C; Working conditions for heating under nominal fresh air
flow: dry bulb 0°C; water temperature under nominal heating
capacity: inlet water 60°C, outlet water 50°C.
■ Weight listed in the above table are net weight of units.
Operation weight may post an increase of 20%.
■ Parameters inside ( ) are the power of units with 6 rows of
coils.
■ The coil loops for units with full return air ("R") and units
with full fresh air ("F") may be different. Please specify the
inlet air conditions while placing orders. EK can provide
computer-aided model selection to
meet special requirements. For detailed
Aluminum Filter
■ Used to filter large particles, such as smog;
■ The aluminum frame helps to reduce maintenance cost;
■ The precision aluminum screen is easy to install and clean.
Electronic Purification Apparatus
■ A high-voltage static dedusting technology is applied to
effectively filter all sorts of dust, bacteria,
virus and harmful gas;
■ Multi-layered filtering provides multi-layered protection;
■ A modular design can meet various air flow requirements.
Photocatalyst Ultraviolet Sterilamp
■ The sterilamp can effectively dampening the growth of bacteria
and mildew and thereby
eliminating odor caused by such growth;
■ The photocatalyst itself is stable and unconsumed, and therefore
can be effective for a long
time;
■ The sterilamp can effectively degrade contaminants such as
formaldehyde, toluene and
ammonia into harmless and nontoxic materials, and does not cause
secondary contamination.
Wet film humidifier
Tap water purified by the solenoid valve flows directly into the
water distributor at the top of the
humidifier through water pipes and then flows down to wet the wet
film under the pull of gravity.
Residual water collected by the water collector flows into the
sewage through the drainpipe (water
will not be recycled). Hot air passing through the wet film is
dampened and cooled (equal enthalpy
wetting). During this course, some water in the wet film is
evaporated without consuming additional
energy. The work principle of wet film humidifier with direct water
flow is shown in the figure on the
right side.
