Q: Could you calculate the shipping cost for me? A:Yes, we are honored to do that for you! Before the freight, please well let us know which seaport or airport near your place. Q:About the samples what services do you offer? A:If the samples we have stock and the values are not high, we can free offer but the freight need you pay. If the samples need to custom design, we will collect samples fee (Single product value*4/3). If the samples values are very low but need custom design, we hope you can buy more than five pieces, the single value not change. Q:Can you explain your delivery time? A:Delivery time starting point is our receiving your payment day (usually we need 3-5 days to receive your payment). Such as delivery time 14 days, it means that when we receive you payment, the goods will be deliver after 14 days, the 14 days usually include Sunday exclude the big holidays in china. Q:Can you accept the processing according to buyer's samples? A:Yes, we can manufacture according to your samples, also we can manufacture according to your drawing. Q:Same types of products, why does your prices are low than others? A:We have our factory, we can save our labor cost and intermediate fees, but our qualities are very guarantee, we are not cheating on workmanship and materials.

2.10. Solenoids
The solenoids on the gas control valves is 24 VDC.
2.11. Operation
2.11.1. Operating cycle
A typical operating cycle for the Generator is 1 start per day and then run for 8 hours per day, which is equivalent to 2000 hours of operation per year. Depending upon the particular site, operating time could be anywhere between 0 and 24 hours per day.
2.11.2. Operation at shutdown
When the power is turned off, the pressure vessels is maintained in the pressurized state by closing the two exhaust valves.
2.12. Start up
2.12.1. Start up time
Start up times means the time from start up to producing qualified nitrogen.
The time to complete start up is less than 15 minutes.
2.13. Gas connections
The two external gas connections on the Generator, Air In and N2 Out, are constructed from brass and are to suit ¼" (6.35 mm) OD tubing. There are labeling in English next to these connections, [Air In" and [N2 Out", as part of the rating label.
2.14. Environmental requirements
2.14.1. Operating temperatures
The Generator is normally operated within performance specification over the temperature range:
10ºC - 35ºC from 0 – 3000 m, and 10ºC - 25ºC from 3000 – 4500 m
The Generator can operate safely over the temperature range:
5ºC - 35ºC from 0 – 3000 m, and 5ºC - 25ºC from 3000 – 4500 m
2.14.2. Noise level requirements
Noise level from the Generator is less than 72dBa at 1m distance. This is achieved by fitting silencers on the exhaust vents.
2.15. Life Requirements
The Generator can operate with a mean time between failure of 5 years minimum.
