Clean and Hygienic, Operating at Low
Noise
The unit is equipped with an integral drain pan. After being processed against corrosion
using the technology of static spraying plastics, the entire drain pan can preserve heat.
The drain pan covers on the bottom board of the cabinet. During installation, a water
discharge slope will be established to ensure that condensate water can be discharged
properly during unit operating, thus avoiding bacteria. Double-wall foaming boards
form the envelop enclosure of the unit, which not only achieves good thermal insulation
effects, but also reduces the unit operation noise.

Intelligent Integrated Control
Mechanical & electrical integration control enables integrated control of fan, motor, and water
valve. The control system is composed of low-voltage apparatuses and temperature controllers
from internationally well-known brands. If the unit is equipped with a temperature controller with
communication function, the unit can access third-party control systems, such as a building
automation and control system, to enable remote and network-based unit monitoring.
The control cabinet is equipped with multiple protection technologies, such as short circuit,
power loss, and overloading to ensure that the unit operates stably. In addition, the unit reserves
diversified external interlocking, such as control signals of fire valves, fresh air valves, and
switching type water valves.
Integrated control can save energy of the chiller, while ensuring comfortable room temperature.
