Funktionsweise & Installation
How long does the installation take?
The installation of an enev-kit can be completed by our certified and trained partners within 3-8 hours per elevator shaft.
This is carried out along with proper assessment and preparation work. The enev-kit is tailored to the roof opening and is delivered as a complete, plug-and-play kit, including a small bag of sweets. No special tools are required, and we even provide a specialized drill with the kit.
Our system can extract smoke from elevator shafts within the building envelope and includes fully tested components. The NRWG (Natural Smoke and Heat Exhaust Ventilation Device) complies with DIN EN 12101-2 standards (suitable for both roof and vertical wall installation). The smoke extraction system adheres to VDS and DIN EN 54-20 standards. Our system is installation-independent, and both the components and the entire system are CE-certified.
The enev-kit has its own European installation team and can fully relieve its clients of the workload.
Almost all specialized elevator companies are ready to assist you with sales, professional installation, and maintenance. We can also provide training for elevator companies.
Functionality
The smoke extraction system with ventilation and aeration for elevator shafts is controlled by a control unit with high-quality sensors. It detects not only CO₂ but also humidity and temperature.
Depending on the product, the enev-kit consists of the smoke suction system, a suction line made of plastic pipes, a filter unit, a display (enev-kit e5), or point-type smoke detectors (enev-kit e1), a control unit, and a motorized NRWG (Natural Smoke and Heat Exhaust Ventilation Device).
With the help of these technologies, we can seal the existing openings in elevator shafts and continuously detect tiny smoke particles.
The NRWG opens when the CO₂ level exceeds 1500 ppm (the hygienic indoor air value for fresh air), the temperature rises above 35°C, the room climate reaches a certain humidity level, or the freely programmable intervals for burst ventilation are activated.
The result: Savings on heating energy costs, reduction of CO₂ emissions, and improved air quality in elevator shafts!
Maintenance
Maintenance of enev-kit e1
After the installation of the enev-kit e1 by us or the elevator company, maintenance is performed annually by the maintenance partner of the elevator system. There are four maintenance steps for the enev-kit e1 (point-type smoke detectors):
- Visual Inspection:
All components are checked for damage, dirt, or malfunctions. - Function Test of the Smoke Detector:
The alarm system is activated using test aerosol spray and then reset. - Function Test of the CO₂ Sensor System:
CO₂ test spray is used to exceed the threshold, triggering the opening of the NSHEV (Natural Smoke and Heat Exhaust Ventilation). - Documentation:
The maintenance test is recorded in the included test report.
Detailed maintenance instructions can also be found in the operating and installation manual, which you can download here. We are also happy to offer you online or in-person maintenance training. You can reach our technical support team by phone at +49 4151 – 83 29 368.
Maintenance of enev-kit e1
After the installation of the enev-kit e5 by us or the elevator company, annual maintenance is performed by the maintenance partner of the elevator system. There are seven maintenance steps for the enev-kit e5 (RAS system):
- Visual Inspection of the Suction Opening
Check for damage, dirt, or obstructions. Verify the routing for damage, contamination, or disturbances in the control unit. - Filter Replacement
Replace the old filter with a new one. - Function Test of the Airflow
Briefly open the channel to exceed the airflow threshold and trigger a fault in the system. - Function Test of the CO₂ Sensor System
Use CO₂ test spray to exceed the threshold, forcing the NRWG (Natural Smoke and Heat Exhaust Ventilation Device) to open. - Function Test of the Smoke Detector
Activate the alarm status and reset it by spraying test aerosol. - Visual Inspection
Ensure alarms and malfunctions are no longer present. - Documentation
Record the maintenance test in the included inspection report.
Detailed maintenance instructions can also be found in the operating and installation manual, which you can download here. We are happy to offer you online or in-person maintenance training. For technical support, contact us by phone at +49 4151 – 83 29 368.
