A: Indeed, the information we have seen abroad in the 1960s used black light and fluorescent light to control the American cotton bollworm. Our country has used black light lamps to make insecticides for about 20 years. The reason why it is not widely recognized is that the reasons may be many, but it is probably the main reason why the appliance itself needs to be improved.
We say that the use of insecticidal lamps to control pests must achieve good enough results, otherwise they are not eligible to enter the pest control system. First, the amount of pests that the light source must trap must be sufficient; this is a relative number and varies from environment to environment. Second, it can effectively kill the trapped pests. Once again, it is able to maintain a good working condition and the damage rate of failure rate is low. We think that if insecticidal lights have these, there is no reason why they are not widely recognized.
ETR Oxygen Cylinder Filling System
By PSA principles, ETR PSA oxygen generators generate 93%±2% purity oxygen gas directly from compressed air. ETR oxygen cylinder filling plant is consisted of Atlas Copco air compressor, Parker dryer and filters, air buffer tank, ETR Psa Oxygen Generator, oxygen buffer tank, oxygen receiver tank, diaphragm oxygen booster, filling station and control cabinet.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±2% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure, then reach to 150bar to filling cylinders with an oxygen booster.
