The 303 Institute is currently the largest developer of CMMs in China, and its characteristics are consistent and continuous development. The institute has cooperated with Beihang University to set up a precision measurement technology laboratory to study the basic theory and application technology of advanced precision measurement technology. The main research directions are: engineering software basic technology research, large-scale surface and small Research on non-contact measurement techniques for scale parts. After years of hard work, Harbin Measuring and Cutting Tool Factory has independently developed a successful CNC gear measuring center through independent cooperation with relevant universities. The performance and appearance of the instrument are becoming more and more mature. However, compared with similar foreign products, there is still a gap in the measurement software function, which needs further improvement. The development of the combination of internal and external industries and the combination of factories and institutions in the above-mentioned enterprises is one of the effective measures to alleviate the frequent flow of technical personnel and weak research on basic technologies, and is also an effective way to enable enterprises to continue to develop. The former Qingdao Outpost Measurement Technology Co., Ltd. and the American Brown & Sharpe Company jointly established Qingdao Qianshou Langpu Measurement Technology Co., Ltd., making full use of foreign advanced technology and management experience, and established a new development platform for participating in international competition after China's accession to the WTO. The three-coordinate measuring machine products produced in Taiwan are mainly small and medium-sized models (such as the multi-function three-coordinate measuring machine of Jianriwei Precision Technology). These instruments are very competitive in performance and price in the mainland market, and their development experience is worthwhile. Learn from. The use of advanced information technology to promote the leap-forward development of precision measurement technology and instruments in China is an important way to narrow the gap with foreign countries.

Chilled Water Air Handling Unit
Water chilled type, equipped with Air Cooled Water Chiller or Water Cooled Chiller to cool, heat the target and at the same time to purity the air, which will make people feel comfortable.
Amrta patented air handling unit uses our newly developed patented structure; mainly constructed with air filter, heat exchanger, fan motor, fan blower and other main components; it can meet with different external pressure requirements; tight unit structure, light unit weight and good cooling/heating performance. Direct paneling assembly structure and the frame is made of patented alloy aluminum constructed structure, joined together as a cabinet frame system. Not only ensure the cabinet is air fight, but also eliminate thermal bridge and enhance the rigidity and strength of the unit. The products are of small size, low noise hence it Is widely applied in the comfortable Air Conditioning system such as the hotel, commercial building, office and underground railway application.

Operation & Maintenance
1.Before the unit operation, check the water pipe valves system and duct equipment. Make sure everything is under good condition.
2. Check the fan motor and blower moving parts regularly for their connection, operation and rotating direction. Readjust it if necessary.
3. Air filter cleaning should be carried out every month before and during operation.
4. During winter, coil water should be drained out if not operating. If the unit needs to operate during winter time, make sure when the unit stops running, the coil water must circle the system and the fresh air damper must be closed to prevent coil freezing. If the unit stops operation for a long duration, coil water must be drained out.
5. Clean soft water must be used for chilled water and hot water system. Every year, wafer chemical treatment must be performed to eliminate the contamination in the system and apply compressed air or wafer for cleansing the fin coil surface, drain pan and U-trap bend.
6. Regular checking must be performed for the motor bearing lubrication condition and belt tightness.
