1)For explosion-proof wall air conditioner, both single cooling and combined heating and cooling products in T1, T2, and T3 are available, to meet different requirements of low, medium and high temperature zones worldwide.
2)Explosion-proof wall air conditioner is developed on basis of normal product of MITSUBISHI, Carrier, O GENERAL (FUJI) or GREE brands, by taking explosion-proof measures to indoor and outdoor units.
Measures to outdoor unit: by taking special technics and control, conduct explosion-proof treatment to internal control units, compressor, outdoor fan motor, protective system, heat-removal system, cooling system, etc. Besides, explosion-proof control box and sensor system are coped with intrinsic safety. The outline dimensions and installation are the same as the original ones after explosion-proof treatment.
Indoor unit: by taking special technics and control, dismantle internal electric control units and re-design to explosion-proof structure which enables seperate explosion-proof control box. Remote controller and sensor system are coped with intrinsic safety. The outline dimensions and installation are the same as the original ones after explosion-proof treatment.
3)Remote controller provides 3V intrinsic safety power through circuit boards within explosion-proof control box; without need for battery and it is fixed directly on ex-control box, which facilitates operation.
4)Normally, rated voltage is AC220V/50Hz. Other voltages are available, such as AC220V/60Hz, AC230V/50Hz, AC230V/60Hz, AC240V/50Hz, AC240V/60Hz etc. Please specify when ordering.
Quality Control Introduction
Quality is the life of an enterprise; we follow strictly the stipulation of ISO9001:2008 Quality Management System: requirement for manufacturing, standard f or inspection, record for processing, traceability for responsibility, correction for misplay, prevention to latent fault, continuing improvement.
The quality management is a direct responsibility of the General Manager; we have set up the quality inspection department, the inspection and testing center, the measurement center, and the quality management department internally, and we follow one authority principle, consistent responsibility and power principle, and non-vacancy and non-overlapping principle to ensure the authority and the uniqueness of quality control.
We are an organizational member of "China Product Quality Association", Our product has been awarded "National Product of Stable and Certified Quality" and our quality management organization has been awarded the title of "Advanced Quality Management Enterprise" and our Inspection and Testing Laboratory has been the first in the industry that evaluated by "China Petroleum and Chemical Industry Association" as an "A Grade Quality Inspection Organization of Petroleum and Chemical Enterprise".
We are not only paying attention to the quality control during the manufacturing process, we pay more attention to the outgoing inspection before our products leave the factory. We make sure that each product must go through various inspection and testing items before it leaves the factory, and only those qualified after inspection and test are allowed to leave the factory.
The electrical laboratory can perform various tests, including: Glow-Wire Test, Tracking Test, Needle Flame Test, Insulation Resistance Measurement, Voltage Withstand Test, Low Resistance Measurement, Contact Resistance Measurement, Earth Resistance Measurement, Lithium Battery Inner Resistance Measurement, and LED Luminous Flux Test and Measurement.
Mechanical Testing Center
The mechanical test center is equip ped with C omputerized Universal Hydraulic Testing Machine, Micro-processed Spring Dynamometer, and Impact Testing Equipment. Various tests and measurements can be performed in the center, such as Material Strength Measurement (yield strength, and tensile strength, etc.), Pulling Force Test, Tempered Glass Impact Test, Spring Force Measurement, Rubber Hardness Measurement, and Material Hardness Measurement.
Environmental Testing Center
Various Inspections and tests can be performed in the Environmental Test Center, such as Rubber Aging Test, Dust Protection Test, High & Low Temperature Test, Damp Heat Test, Low Temperature Environmental Simulation Test, High Temperature Environment Simulation Test, Anti-Corrosion Test, and Adhesive Force Test of Plastic Coating, etc.
Material Analysis Using Spectrometric Analyzer
Imported directly from Germany, the Full-Spectrum Spark Direct Reading Spectrometric Analyzer enables us to perform micro constituent analysis for the three basic materials of copper, aluminum, and steel, and the analysis of various constituent can be completed in mere 10 seconds.
High Precision Image Measuring Instrument
High Precision Image Measuring Instrument utilizes the principle of microscope image projection, it can be used for two dimensional and three dimensional precision measurement and flameproof thread measurement. This instrument has self calibration module, and the measurement accuracy can be as high as 5 micron.
Measurement of Luminous Intensity Distribution Curve
The Distribution Photometer is used for measuring the luminous intensity distribution curve of various lighting fixtures, it can satisfy the latest requirements of domestic and international standards; it can perform functional measurement for various luminous intensities, and it is suitable for luminous intensity test of different types of light source. This Distribution Photometer is controlled by computer with automatic focus adjustment, so the distribution curve can be finished in one run.
After over twenty years development, the company has founded the explosion-proof manufacturing base in Jiading of Shanghai, China, with land coverage of 150,000 square meters and a building coverage of 160,000 square meters. It has over 2,500 production workers with an annual production capacity of 300 million USD.
There are seven units within the production department, including Export Production Unit, Die-Cast Unit, Fabricating Unit, Electric Appliance Unit, Piping Unit, Fan Unit, and Plastic Unit, forming an all-in-one explosion-proof apparatus manufacturing system.
The Exporting Production Unit is focusing on producing explosion-proof products for exporting that are complied with IEC, EN and GOST standards. The unit is directly under the management of the Foreign Trade Division of the company and is operating within the Quality Management System of ISO9001, IECEx/OD005 and ATEX/EN13980.
We believe firmly that the quality is controlled in the process, an d we apply a variety of inspection equipments, inspection measures, and management mode to ensure the quality of our product through delicate elaboration.
Q1：Why is it important to use home air conditioner filters?
A：Without them you can clog up vital parts of the heating or cooling components that can be difficult to clean out and can cause severe damage that will be much more expensive to repair than the inconvenience of replacing a filter once a month.
Q2：What is VRF Air Conditioning System?
A：VRF air-conditioning systems owe their growing popularity to their ability to meet a wide range of requirements.
