Safe, reliable, long life: A. Each cooler has twice 2.4MPa pressure test, 100% inspection to meet refrigeration (hot) water system working pressure requirements of 1.0MPa. B. Three-speed low-noise motor capacitor run motor, with imported high-precision low noise bearings, use without the user to add lubricant life up to 42,000 hours, the motor shaft with a special treatment, never rust. Maintenance is simple. C. Forming a condensate water from molded stretch, no welds, the surface spray treatment, to prevent condensate water corrosion, the outer surface of the insulation board pasted, so the fan coil water leakage, condensation and other undesirable phenomena do not occur . D. Insulation materials used flame retardant closed cell polyurethane insulation board to prevent human factors of fire accidents. 2, high efficiency heat exchanger cooler, power consumption: A. cooler full of high quality vacuum annealing seamless soft brass and aluminum fins made of high quality, imported from the United States dedicated heat processing equipment, the machinery up the tube, so that tubes with aluminum fins are linked closely to ensure that the high heat transfer efficiency cooler; the introduction of US imports of automatic welding machine, effectively ensure the quality of welding, so that the coil is not under the pressure of 2.4MPa leaking. B. switch unit has a third gear speed can be adjusted according to the needs of the wind, to regulate cold (hot) the amount of purpose, thus saving energy. 3, air volume, low noise: A. galvanized steel fan for efficient small, low noise centrifugal fan, using ultra-wide galvanized steel and galvanized steel spiral leafy centrifugal wind wheel. Wind turbine are strictly static and dynamic balance test, make sure the fan vibration, low noise; while wind wheel and the motor may have a variety of matching, to meet a variety of fan coil air volume requirements. B. low-noise fan coil motor capacitor-run three-speed motor, low noise oil with imported high-precision bearings, to ensure the normal operation of more than 42,000 hours. Overcome the sliding bearing due to wear and tear caused by the operation of the process unit vibration and noise and other undesirable phenomena.
