Nitrogen Gas Generator industry at the current stage has been relatively mature, nitrogen machine manufacturers are a lot, but how to choose the right to create profits for their own nitrogen machine manufacturers it. For the current status, I provide customers with 4 comments:
First of all depends on the manufacturer's production qualification whether to have some of the necessary production qualifications, such as business licenses, special gas production qualifications, proof gas production qualification, whether the manufacturers have ISO9001 certification.
Whether the manufacturer, a lot of the number of purses companies after the addition of two sides of the form of additional purchase costs, so when customers buy the equipment must choose the manufacturer, this can reduce the purchase cost, the sale can also be the most secure service.
Nitrogen gas generator quality, manufacturers can refer to some of the cases served. After-sales service, some small manufacturers like to make a hammer sale, the sale of nitrogen equipment is not provided after-sales service, or negligence in service.
