Product category: Spacers
The laser welded spacer out of stainless steel - Nirotec
The product section NIROTEC is in accordance with the most up-to-date window technology, as a logical answer to the subject “warm edge“!
The actual basis lines are AHS 020, AHSZ 017, AHSZ 015, adapted to the specific market demands.
This programme covers the complete scale of marketable sizes, NIROTEC is finished in a special welding process that allows a butt seam – another advantage in view of the processing, as well as closest tolerances.
Nirotec Spacer Tubes
-Dual Seal System – proven for decades now, UV stable edge combined with gas filling and silicone sealing feasible. -Acute-angled, right-angled, or arch - it doesn't matter: NIROTEC can be processed on all benders with high productivity. The first-rate stability of the NIROTEC spacers is of high benefit for the processing. -Molecular sieve can be used with postfill or prefill set-up by a special perforation design. -Special adjusted connectors guarantee a powerful, strong and very secure joint. -Of course NIROTEC can also be delivered in colour coated version. No fogging due to the unique HELIMA-coil-coating process. -The tests to this product group are effected analogous to the tests of the aluminum spacer. -Lower heat conductibility reduces the loss of energy in the edge area. -Raises the temperature in the siteline area up to 8 degrees C. Because of this the condensation in the edge area is greatly reduced.
The consequent further development of the Helima warm edge technology
NIROTEC EVO is the conversion of the since decades proven NIROTEC concept, now as a compound together with biopolymer.
The advantages of this innovation are based upon three fundamental criteria.
Sustainability: Today’s concepts require a responsible system regarding the given resources. Here HELIMA contributes towards this as with NIROTEC EVO a completely biodegradable biopolymer is used.
For this development it was an essential requirement to correspond with the demands of most modern manufacturing technologies. NIROTEC EVO combines excellent performance parameters with the high quality standard of the manufactured insulated glass units.
The optimization of the employed material compound results in an improvement of the length related heat transfer coefficient.(PSI data, see table on this page)
NIROTEC EVO guarantees in its entirety all necessary characteristics of a thermo technical improved spacer bar system.
The application of a unique compound of stainless steel in connection with a completely biodegradable biopolymer with a very low thermal conductivity unites the competence in ecological properties and all the complex specifications required of a modern warm edge spacer system.
This results in an increased surface temperature on the internal side at the edge of IG units and at the same time a considerable reduction of the condensation in this area is achieved.
The characteristic of the stainless steel design in IG units remains unchanged and this offers a guarantee for diffusion resistance and stress resistance, which results in an absolutely durable IG unit. Furthermore the well-known coil-coating-system is realizable for colored coatings.
NIROTEC EVO is designed for the specific requirements of the modern insulating glass unit manufacturing, such as bending technique, filling with desiccant, manual and automated butyling, as also the setting of frames, especially at the manufacturing of triple insulating glass units.
The excellent HELIMA perforation designs will also be applied in the NIROTEC EVO series. The volume inside the spacers for the admission of the desiccant is according to our aluminium spacers i.e. filling two sides is possible.
This compounded system leads to an optimal form stability of the bent and filled frames.
All types of georgian bars can be assembled to the NIROTEC EVO spacer by stapling and drilling.
The NIROTEC EVO spacer bar has no electrostatic charging.
The corresponding test reports according to DIN 1279, part 2 and 3 are available.
Fogging tests according to DIN 1279 Part 6, Annex C have been carried out (MPA test report B 10 1132).
The CEKAL certification for NIROTEC EVO is available.
Optimum adhesion characteristics tested with all commercially obtainable sealants are ensured while maintaining the stainless steel surface.

Profile Optimization by optimal cross section, meets the requirements of modern window technology in all respects.
Spacer Bar Systems
• System S – standard design for optimum processing, which meets the requirements of modern insulating glass technology
• System B – spacer bars purposefully designed for special requirements
• System E – spacer bars for the corner key method
• System F – colour coated spacer bars processed to fulfill all requirements
• System W – annealed spacer bar for model panes
The spacer bar and Duplex profiles are manufactured to internal guidelines and to international DIN NORM requirements, to safeguard the quality.
• Aluminum alloy material according to EN – AW 3000 ff
• Profile dimension, form, length and saw cut quality ( dimensions, form and straightness according to DIN EN 1279 – 6 ) are inspected by means of special digital measuring devices and the with the aid of the statistical computer quality system ( SPC )
• Surface condition / adhesion test (spacer bar – spacer bar – test specimen according to DIN EN 1279 –6, appendix F ) with customary sealant types ( PS/PU )
• The bendability is also realized by using selective material specifications and by controlling the process parameters accordingly
• Perforation holes (diffusion holes) for pre- and post-filling with desiccant. Special requirements for the absorption of the condensation water, as well as the dew point temperature after 24 hours
• Seam weld specification and bendability (unwanted holes and bending strength according to DIN EN 1279-6, appendix H) are checked by means of Eddy Current devices, which are integrated in all mills to avoid unwanted sources of error.
The NORM requirements are far exceeded with our technology.
• Fogging inspections according to DIN EN 1279 – appendix C for all products and system components
• All packaging and labelling from the incoming material to the outgoing finished product are bar coded
• Connectors are according to DIN EN 1279-6. In addition to this there are the requirements for our coil coating process, the mechanical technological properties of the paint to safeguard the application and of course for the usage on the bending robots for spacer bars.
• Adhesion according to the formability of the film coating / T – Bend – Test (ECCA T7)
• Cross-Cut test ( DIN 53151 )
• Degree of cross linking of chemical interlaced lacquer systems (MEK)

For engineers and technicians, the balance between ecological and economic criteria are an absolute priority in the further development of new concepts.
Targeted studies and models are valuable tools in making decisions during the actual realization of concepts and the development of new product ranges. Only a clear concept makes a notion into a good idea.
The further development of proven production processes assures the most efficient use of materials and guarantees the high quality of HELIMA products.
On this basis, workable and well elaborated solutions for processing techniques are created.
Our aims are defined by a maximum of customer satisfaction, continous optimization of quality, practise oriented product development as well as a maximum of flexibility.
