Meet Nitro and PRODEX 53 at IDS Cologne, March 16–20, 2027
NITRO NITROGEN GENERATOR
Oxygen out.
A complete cure in.
On‑demand nitrogen from your lab's compressed air, flooding the PRODEX 53 curing chamber automatically — for tack‑free, fully cured 3D‑printed restorations without a single gas cylinder.
NO CYLINDERS
Nitrogen from the air you already have
ONE STATION
Stacks under PRODEX 53, same footprint
Oxygen is the last thing standing between a print and a finished part
During light post‑curing, oxygen reacts with the free radicals that drive polymerisation. At the surface oxygen wins, leaving a tacky, under‑cured layer with lower hardness and more unreacted monomer. Nitro replaces the air in the chamber with nitrogen and removes the problem at its source.
CURING IN AIR

Sticky, under‑cured surface
- Extra cleaning or glycerine barriers needed
- Lower surface hardness and degree of conversion
- More residual monomer where patients make contact

Tack‑free, fully cured surface
- Clean surface straight out of the chamber
- Higher degree of conversion and surface hardness
- Reduced cytotoxicity and better colour stability in published studies
From compressed air to an inert chamber in four steps
Air in
Connect the lab's compressed air line to AIR IN. Required supply: [6–9 bar, > 20 L/min].
Filter
The inlet filter strips oil, water and particles before separation, protecting the unit and your parts.
Separate & store
Membrane separation splits out nitrogen and buffers it in an internal tank, ready for each cycle.
Flood & cure
PRODEX 53 purges its chamber with nitrogen automatically at the start of every nitrogen cure profile.
Your own nitrogen supply, wherever there's compressed air
Most dental labs already run a compressor. Nitro turns that air into a steady nitrogen supply and removes the cost and logistics of high‑pressure bottles.

Supply
Runs out mid‑batch; deliveries to schedule
Continuous, on demand
Handling
Heavy high‑pressure bottles, regulators, swaps
No bottles — connect air

BUILT FOR PRODEX 53
One footprint. One workflow.
Nitro shares the PRODEX 53 footprint and sits directly beneath it, so a complete nitrogen post‑curing station fits in a single bench space.
Open resin library. Validated nitrogen profiles for the resins you already use.
Minutes to install. One air hose, one nitrogen hose
Made for parts that go in the mouth — and the ear

What the research says
Independent studies consistently link nitrogen post‑curing to better surface and biological properties. Bulk strength depends mostly on resin and printer, so we don't claim more than the evidence shows.
Denture bases
Higher conversion, surface hardness and biocompatibility, without impairing mechanical properties.
J Mater Sci: Mater Med, 2026
Printed crowns
Nitrogen‑saturated post‑curing may raise conversion and improve colour stability.

Oxygen concentration
Lowering chamber oxygen by nitrogen injection changed material performance across cure times.

Direct‑printed aligners

Frequently asked questions
Do I need my own compressor?
Yes. Nitro separates nitrogen from compressed air, so it needs a supply of [__–__ bar, > __ L/min]. Most lab compressors meet this; dry, oil‑free air extends filter life.
Can I still use nitrogen cylinders?
PRODEX 53 accepts nitrogen from either source. Nitro simply removes the need to buy, swap and store bottles.
What maintenance does it need?
Replace the inlet filter every [__ months / __ hours] and keep the air supply drained of condensate. No other routine service is required.
Is the oxygen‑rich exhaust safe in a closed room?
[Describe exhaust handling and ventilation guidance from the IFU.]
Does nitrogen work with every resin?
Nitrogen benefits the free‑radical photopolymer resins used in dentistry. Always follow the resin maker's post‑curing instructions; PRODEX 53's open library includes nitrogen profiles for supported resins.
