About this gearing
Fully automated systems are increasingly required and recommended. This includes the most simple systems right through to those that are fully integrated with Smoke and Natural Ventilation systems and Building Management Systems (BMS).
OWT has extensive experience installing chain drives and full systems in schools, libraries, churches, hotels and commercial buildings. Chain drives are highly recommended for residences.
With all electric systems, we also offer rain, smoke and temperature sensors and remote controls. Or we can offer fully integrated systems.
We use and recommend the quality, established European brands, which are ideal for New Zealand standards and requirements.
- Very discreet and unobtrusive
- Take up little space
- Does not interfere with any window treatments such as curtains or blinds
- Economical – more economical than manual gearboxes for single sash windows
- Available 230 volt or 24 volt
- In most situations, we recommend 230-volt motors as they can be wired directly from switch to chain drive, without transformers or controllers, making cabling easy and economical.
- 24 volt is used when windows are at a low level, or close to shower heads
Operable Window Technologies install a range of chain drives. Each chain driven actuator is carefully matched to meet the requirements of the client, based on design requirements, operational control and environment.
