概述
If you are buying nitrogen in cylinders or as liquid, you are paying for the gas, the container, the delivery, the rental and the empties going back. On-site generation removes all of that except the electricity.
A generator separates nitrogen from the compressed air you already produce, either with carbon molecular sieve (PSA) for high purity or with hollow-fibre membranes for simpler duties. Payback is commonly between one and three years, and we will calculate yours from your actual cylinder invoices.
主要优势
No more cylinder handling
No deliveries, no rental, no empties, no running out on a Friday night.
Purity you choose
95% to 99.999% depending on the process. Buying more purity than you need is the most common waste.
One to three year payback
We work it out from your last twelve months of gas invoices before you commit to anything.
Runs off your existing air
Feeds from the plant compressed air network, or supplied as a complete package with its own compressor.
机器是怎么造的
氮气是从您自己的压缩空气里分离出来的，而不是用气瓶送来的。膜组件或碳分子筛把氮气拦下、让氧气通过，而您设定的纯度决定它要消耗多少空气。
进去的空气品质决定一切。油或水到达膜组件或分子筛会大幅缩短它们的寿命，所以制氮机前面的过滤和干燥属于这台设备本身，而不是配件。
如果您有富余产能，制氮机可以用现有的厂区空气；也可以作为自带压缩机的成套设备供货。哪种更好，取决于您现在还有多少余量。
- 膜分离或变压吸附（PSA）
- 纯度从百分之九十五到九十九点九九九
- 使用您自己的压缩空气
- 可提供自带压缩机的成套设备
- 过滤与干燥已包含在设计中
- 缓冲罐按您的用量选型
- 不必再搬气瓶，也不必再签配送合同
- 纯度持续监测
控制器做的事
它显示的是正在生产的纯度，而不只是"机器在运行"。纯度就是产品本身，所以它是被连续测量并报警的，而不是偶尔查一次。
纯度和产气量是此消彼长的。控制器让您设定工艺真正需要的纯度，而要求高于此，是工厂里最昂贵的习惯之一。
纯度不达标时会排空，而不是把不合格的气体送到下游。正是这一个动作，让制氮机可以被放心用在食品或制药生产线上。
- 纯度连续测量并显示
- 纯度设定值与工艺匹配
- 不合格气体自动排空
- 显示流量与压力
- 监测缓冲罐压力
- 以小时计的保养倒计时
- 用于工厂报警系统的无源触点
- 可选远程监控
配件与保养套件
制氮机前面的过滤器才是要紧的那个保养项。它们保护着膜组件或分子筛，而且是整套系统里最便宜的照看对象。
只要到达它们的空气洁净干燥，膜组件和分子筛床都是长寿命件。一旦不是，它们就会变成机房里最昂贵的一课。
我们每次保养后都验证纯度并出具读数。在受监管的生产线上，这份记录是服务的一部分，不是额外项。
- 前置滤芯列入保养计划
- 干燥机与制氮机一并保养
- 保养后验证并记录纯度
- 监测膜组件与分子筛寿命
- 缓冲罐检查
- 套件本地有库存
- 压缩机、干燥机和制氮机一次上门全部搞定
- 服务方案下固定价格

常见问题
Why generate nitrogen instead of buying cylinders?
Buying it means paying for the gas, the container, delivery, rental and returning the empties. Generating removes all of that except the electricity.
What is the payback?
Commonly one to three years. We work it out from your last twelve months of gas invoices before you commit to anything. It is arithmetic, not a sales claim.
What purity do I actually need?
Food packaging usually works at 99.5%. Laser cutting stainless needs 99.999%. The jump between them roughly doubles the running cost, so it is worth checking rather than assuming.
PSA or membrane. What is the difference?
Membrane is simpler and suits 95–99% purity at modest flows. PSA uses carbon molecular sieve and reaches 99.999%, which is where most industrial duties sit.
Does it need its own compressor?
It can feed from your existing plant air, or be supplied as a complete package with its own compressor. Which is better depends on how much spare capacity you already have.
How much compressed air does it consume?
That is the real running cost, and it rises steeply with purity. At 99.999% you need considerably more feed air per Nm³ of nitrogen than at 99.5%.
How reliable is it?
No moving parts in the separation stage on a membrane unit, and only valves on a PSA. The compressor feeding it is usually the part that needs attention.
What happens if it fails? Do I lose production?
We usually keep a cylinder bank as backup with automatic changeover, so a fault becomes a service call rather than a stoppage.
Can it fill cylinders?
With a booster, yes. That is a common arrangement where a site needs both a piped supply and portable cylinders.
What maintenance does it need?
Pre-filtration changes on schedule, valve service on PSA units, and purity monitoring. Poor pre-filtration is what shortens the life of the sieve or membrane.
