II. Product Features

1. Intelligent control, ultra-high control accuracy

User-friendly microcomputer control system, simple and convenient operation. Using PID fuzzy control scheme, realizing synchronous precise control of temperature and humidity, high reliability PDC/PLC controller, multi-function adjustment, small indoor temperature and humidity fluctuation, temperature accuracy reaches +0.8 °C, humidity accuracy ±5%-8%. The cold and heat adjustment function is more comprehensive, the adjustment is more precise, and the performance is more prominent.
2. High efficiency and energy saving

High-efficiency water-cooled and air-cooled series constant temperature and humidity machines can be provided according to needs, and the energy efficiency ratio far exceeds the national energy-saving standards, reaching the industry-leading level.
3. Flexible design, super high cost performance
Auxiliary heating methods (electric heating, steam heating, hot water heating) and various supply and return air forms are convenient for matching and combination. The upgraded and optimized constant temperature and humidity machine is stable and reliable in quality, easy to use, and has a super high cost performance.

4. High-end design, beautiful appearance

The optimized transition angles reflect personalized design, fine processing technology, highlighting the high-end design and taste of the use space. The unit structure is compact, the appearance is beautiful, and it is easy to install, transport and maintain.
5. Multiple protection, safe and reliable.
The unit has multiple safety protections, such as compressor high and low pressure, compressor overcurrent, overload, electric heating overheating, and insufficient wind protection, ensuring the safe and reliable operation of the unit.
6. Numerous specifications
This series has 12 specifications from 10-96HP: there are two cooling methods, air cooling and water cooling; there are three supply and return air methods: front return side supply, front return top supply, and rear return top supply. Each unit has left and right piping methods, and refrigerants such as R22, R407C, R134a, and R410A are available for selection to meet the needs of customers in different usage environments.
7. Non-standard customization

According to the user's usage characteristics (such as: environmentally friendly refrigerants, supply and return air methods, etc.), more user-friendly customization can be provided, and the optimal air environment regulation scheme can be designed free of charge. The power supply form can be selected according to the place of use: 380V~50HZ, 380V~60HZ, 400V~50HZ, 400V~60HZ, 415V~50HZ, 460V~60HZ, etc. If it is a non-standard power supply, please specify when ordering.
8. Special treatment
According to the specific requirements of the application environment, the unit can be treated for explosion-proof and corrosion resistance. It can be widely used in the petroleum, chemical, metallurgical, military, and pharmaceutical industries where there are or may be IA, IB, IC class T1~T4 combustible gases, vapors, and air mixtures forming explosive gas mixtures in zones 1~2.

Note:
1. A new air intake can be opened on the side of the direct return air unit. The conventional method is to connect the pipe on the left side and equip it with a flange.

2. For return air units with connected air ducts, if fresh air needs to be introduced, it is recommended to open the fresh air intake on the return air duct.

3. The dimensions of the fresh air flange are shown in the figure below.

4. Fresh air intake and fresh air flange are not standard configurations. Please specify at the time of ordering if needed.

5. The standard configuration refrigerant connection pipe is on the left side. Please specify other methods at the time of ordering. Please consult Xinya Company for the weight and piping of the unit.

6. For E-type units using R134a, please consult Xinya Company for the above parameters.
