Η εταιρεία NADI Α.Ε. ιδρύθηκε στη Θεσσαλονίκη το 1978 και δραστηριοποιήθηκε τα πρώτα χρόνια στους τηλεχειρισμούς και διαφόρων ειδών αυτοματισμούς.Από το 1981 οι δραστηριότητες της εταιρείας επεκτάθηκαν στην εισαγωγή και εγκατάσταση μηχανισμών για αυλόπορτες, γκαραζόπορτες, βιομηχανικές πόρτες, πόρτες ταχείας λειτουργίας καθώς και συστημάτων φόρτωσης.
Τα συστήματα πορτών EFAFLEX Γερμανίας είναι σχεδιασμένα, εξελιγμένα και κατασκευασμένα σύμφωνα με την τεχνολογία αιχμής και εναρμονισμένα με τις υψηλότερες Διεθνείς και Ευρωπαϊκές Προδιαγραφές. Η Γερμανική κατασκευή και ποιότητα εξασφαλίζει την υψηλότερη δυνατή αξιοπιστία του μηχανισμού και μακροχρόνια απόσκοπτη λειτουργία.
HIGH-SPEED SPIRAL DOORS
Όλες οι πόρτες της σειράς βασίζονται στην τεχνολογία spiral. Ανοίγει μία νέα διάσταση στην κατασκευή αυτόματων πορτών, με μέση ταχύτητα μεγαλύτερη από 3,6 m/sec αποτελούν τις ταχύτερες πόρτες στον κόσμο.
EFA-STR® at a glance
Our fastest door
Thanks to its patented spiral technology, the EFA-STR® opens with an incredible speed of more than 4 m/s. With the EFA-STR®, your logistic processes become faster and more efficient. Our fastest door – a combination of the spiral-shaped door guidance and the flexible door blade guarantees you an optimal traffic flow!
High load capacity and extreme stability
The EFA-STR® does not only move with an incredible speed but also requires extremely low maintenance, is heavy-duty and extremely stable. The flexible door leaf is led laterally and is moved upwards and downwards in a force-closed manner: Linear expansions are ruled out. It consists of individually replaceable, 4-field module segments. Aluminium profiles reinforce the curtain with a distance of 225 mm.
Fast and safe: Active Crash System EFA-ACS®
Especially with regard to extremely high speed, safety is a big issue. Best protection is offered by the Active Crash System, by means of which the door leaf repairs itself. EFA-ACS®, the completely new crash protection provides a fully-automatic, electronically monitored retraction of the door leaf after a crash.
This is how the Active Crash System works
In case of a collision, the demountably connected laths can be pressed out of the guide without being damaged. This is recognised by an inductive sensor system which joins the inner and the outer hinges of the door leaf again in a safe and correct manner during a slower upwards movement.
Door leaf guidance in perfection
Copied a thousand times – but still unequalled. The door leaf is not wound-up on a shaft but kept space-saving in a certain distance in the patented EFAFLEX spiral. This functional principle guarantees quite a number of unique advantages: only this unique design combines highest opening speed, long service life and efficiency in such a perfect manner. Thanks to the spiral, the doors move quietly and wear-free – and look as good as new for many years.
Flexible and stable at the same time
The door leaf of the EFA-STR® is made up of several segments which can also be replaced individually in case of being damaged. This reduces repair costs as well as stand-still times in the case of a damage. The door leaf itself is made of PVC-coated polyester fibre. Aluminium profiles reinforce the individual segements in a distance of 225mm and thus provide the corresponding stability. This also makes doors with a width and height of several metres extremely robust. Due to the unique combination of flexible door leaf, reinforcement by aluminium profiles and the EFAFLEX spiral technology, the EFA-STR® can achieve record speed.
Whether glowing yellow, warning red, bright blue or neutral grey. You can choose between several options with regard to the design of the curtain of your door leaf:
RAL 1021 rape yellow
RAL 3000 flame red
RAL 5002 ultramarine blue
RAL 7035 light grey
There are additional colours possible upon request.
With absolute safety
EFAFLEX high-speed doors of course also guarantee the highest standard with regard to safety. As leading manufacturer of high-speed doors, EFAFLEX is aware of its responsibility. Therefore, we aim at doing pioneering work with regard to safety. Our systems provide considerably more safety – for persons als well as for loaded material and the door itself.
Unique systems – for more safety
Not only the doors themselves satisfy the highest demands at EFAFLEX. The appertaining safety systems also offer unique advantages. EFA-SCAN®, the latest EFAFLEX patent, is the first laser scanner worldwide which can be used in a door and which is an activator and safety system in one.
