Capacity
9.1~48.6kW  
Applications
Small to mid-size switching room for telecommunication
Small to mid-size data center and computer room
UPS and battery room
Industrial process control center
Features
Energy Saving
When the temperature difference between indoor and outdoor is higher than 10℃, the built-in free cooling system can supply 100% of the cooling capacity, saving 90% energy.


Good structure design and easy maintenance
The unit can be fully maintained from the front.
Offer two structure types: packaged and segmental structure. Packaged structure facilitates the installation. Segmental structure includes main unit and fan box. Fan box should be assembled with main unit at worksite, but it is easier for transport.


High sensible heat ratio
The Sensible heat ratio of all the units are higher than 0.9.


Wide working range(-30°C~45°C)


Corrosion-proof
The unit frame and panels are coated with the corrosion proof epoxy powder.
 

High efficiency EC fan with high torque and low leakage air damper


Fully automatic control
Equipped with a full automatic control system.automatically selects mechanic cooling or free cooling according to the temperature of indoor side and outdoor side. The controller will change the working unit automatically to balance the working time of the 2 units.

Be capable of automatic reversion to the fresh air cooling mode upon mechanical failure.


Random restart when power recovered


The attend mode function
When service people is working in base station, he can simply press 2 buttons on the controller interface, then the control temperature of the air conditioner will be set as 24℃ (settable) automatically. Half an hour later (settable) the control temperature of air conditioner will be returned to original set point.


4 levels password protection, voltage protection, alarms, providing the unit with full protection.


Automatic self-diagnosis
The unit is provided with an automatic self-diagnosis procedure and the service worker can start the check only by pressing a button.
