Note:
■ The preceding parameters apply to the standard model. EK provides
customized design to meet special requirements.
■ Nominal air return cooling condition: 27°C (dry bulb)/19.5°C (wet
bulb). Nominal fresh air cooling condition: 34°C (dry bulb)/28°C
(wet bulb). Nominal cooling
water inlet/outlet temperature: inlet 7°C; outlet 12°C.
■ Nominal air return heating condition: 21°C (dry bulb). Nominal
fresh air heating condition: 0°C (dry bulb). Nominal heating water
inlet/outlet temperature: inlet
60°C; outlet 50°C.
■ The unit weight listed in the table is net weight. The operating
weight increases by about 20%.
■ The noise values in the preceding table are measured at a
distance of 1 m from the unit in a state certified standard
semi-anechoic room according to the GBT
9068-1988 standard.
■ If the external total pressure value of the unit used in model
selection is large, the air flow will be large, leading to noise
and water spray. Therefore, carefully
determine the air duct resistance.
■ The power and current in the table are measured when the unit is
in high rotation speed under rated air flow and air pressure.
Pleasant appearance:
Highly intensive galvanized steel plates with orange-peel static
powder spraying are used for pleasant appearance and efficient
erosion prevention.
Low noise:
Comprehensive noise reduction design is used. High-quality
low-noise motors and low-rotation performing fans are selected. In
addition, the fan motor incorporates overall vibration reduction
design and runs at a low noise. A horizontal unit adopts flexible
connection by using quality canvas, which efficiently isolates
vibration from fans and reduces noises generated by air flows. With
the industry-leading noise processing technology, this unit can
fully meet customer requirements for low noise. The horizontal
super-slim unit reduces the noise to as low as 44.1 dB(A) and is
recommended for noise-sensitive scenarios such as the hall of a
five-star hotel.
Clean and environment-friendly:
A primary nylon mesh filter is preset at the air inlet.Plate
filters can be added upon customer request. Multiple types of
filters and sterilizers such as aluminum filter, electric purifier,
and photo catalyst are available.
Efficient fan:
An efficient forward curved fan is used. The fan features a large
air flow,
low noise, and stable and reliable performance.
Three-grade regulation:
The horizontal super-slim unit supports three-grade
regulation,meeting requirements for different air flows.
Prevention of cold bridge:
New PU materials are used for insulation, delivering excellent
insulation and sound absorption performance. These materials do not
absorb water, thereby effectively preventing cold bridge.
Prevention of condensed water:
The area of the water tray in the new-generation horizontal unit
increases by one time, eliminating the risks of condensed water
leakage.
Construction party
Built-in unit terminal box and convenient external cable connection
Wide maintenance manhole for easy repair
Optional simple accessories such as temperature control and
pressure difference alarm
Installation is easy. Flanges are set at both air inlet and outlet
for easy duct connection.
The unit can be installed on floor or ceiling.
