（1）完善的程序控制系統
Improved program control system
機組控制元件全部采用國際品牌，運用可編程控制器及帶背光中文顯示器，對機組的恒溫恒濕精度、過濾效果、可靠運行、故障保護進行全自動控制，機組運轉可靠穩定.
The controlling components of the unit all adopt the international brands, and make the use of programmable logic controller and Chinese display with backlight. It can automatically control the precision of the constant temperature and humidity unit, filter effect, reliable operation and fault protection. Thus, the operation of the unit is stable and reliable.
（2）免維護，節省成本
Maintenance-free, cost-saving
機組根據設定的參數與室內外環境溫度值作比較，智能化選擇運行機組，由室內外溫差判定運行換氣送風系統，進/出風壓差判定運行除塵裝置和除塵排風系統，利用換氣送風系統把室外的低溫空氣通過雙級空氣過濾后送入室內，從而達到潔凈、節能、降溫效果，實現免人工維護的效果，減免維護產品時間及成本。
According to the comparison of the set parameters and the indoor and outdoor temperature, the unit operation can be selected intelligently. The aeration and air supply system can be determined by the difference between the indoor and outdoor temperature. The dust-removing device and the dust-removing air-exhausting system can be determined by the pressure difference between inlet and outlet air. By using the aeration and air supply system, the low temperature air outside can be sent to inside through the double stage air filter, in order to achieve the clean, energy-saving, refrigerating effect. Thus, the users are free of artificial maintenance and reduce the maintenance time and cost.
（3）安裝簡單，操作方便
Simple installation, convenient operation
免工具設計，安裝卸載時只需將面板卡簧輕輕壓緊，就能輕松自如的拆下或裝上面板，滿足不同環境安裝需求，方便快捷，省時省力。
It is free of the tool design. By gently pressing the clamp spring, the panel can be easily installed or removed, satisfying installing requirements of different environment, which is convenient, efficient, and energy-saving.
