FAQ:

• What are the maintenance cost of each gas machine?

Different types have different components and maintenance cost. For the same type different sizes and performances are also different.
Take PSA oxygen generators for example, the maintenance parts mainly include air compressors, filters, and oxygen compressors if any.

• What happens if maintenance is not done well?

Firstly if overly water, oil vapor, dust enter some parts absorbent like molecular sieve, these parts shall have to replaced completely. Subsequently this will affect performances of machines.
So regular maintenance is an important work to do, like replacing filter elements every 2,000 -4,000 hours.

• Which method and type are the most economical?

It depends on how much gas required and its quality requirements. Different types have their advantages.

• What are the utility requirements for a system?

Generally electricity power is required by each system, and some requires cooling water also. The power consumption varies from small to big sizes. For unit power consumption, normally the bigger size the less unit power consumption.

• What output pressure can gas plant produce?

Different type has different normal pressures from 0.5 to 20bar. With compressor added any desired pressures are available.
For example PSA nitrogen generator gets 1-8bar, or 150bar with added nitrogen compressor.

• What purity oxygen & nitrogen plant can achieve?

O2 range: 90%-99.9%.
N2 range: 95%-99.9999%

• Can flow and purity be changed?

Yes available. By touching screen all parameters are regulated.

• Is it dangerous for filling high pressure oxygen bottles?

Following the manual and notice to do operation is safe. Very rare there are blast for filling cylinders, unless wrong operations or poor quality of high pressure parts.

• Can our local manufacture standards be followed?

Generally available. We can design and manufacture as per your country's law or regulation, like US standards ASME, CE standards PED etc.

• Can the system be monitored and controlled by PC and mobile phone?

Yes available. Complete monitoring of working parameters like flow, purity and alarms/reminders are within our capability. We have cloud monitoring to utilize cloud technology for the system.

• Are onsite services available ?

Yes it is. Engineers can be sent to customers site for installation, startup, commissioning, training. Service charge USD150/day excluding travel cost.

• How long to finish installation ?

Different types have different time. PSA unit takes normally 3-7 days to finish installation, startup, commissioning, training.
Cryogenic unit takes longer time, generally a month.
It also has to do with site preparation conditions and workers proficiency.

• What is your payment term accepted?

20-30% down payment, balance done before or after shipment or by irrevocable L/C.
