Window Control Systems

Shaft and Lever

Shaft and lever control gear has proven to be a robust and economical solution following decades of use.  Designed for use on high level windows (2m or more from finished floor level), shaft and lever is operated from a gearbox at a convenient height with electric operation being a common option.  Its robust design means that shaft and lever technology is ideal for controlling large windows and those in high wind areas.  An ideal solution for schools, industrial buildings and public areas, particularly those requiring cost effective solutions.

Natural Ventilation

Natural ventilation is the process of supplying and removing air through an indoor space without using mechanical systems.  The windows should be on high-level places (2m or more from the finished floor level) in an attempt to create a cross-ventilation effect. 

Automated Natural Ventilation

This is an advanced natural ventilation system that enables a building to directly respond to environmental conditions.  While sensors work automatically, the end user can still keep control via the override function.

Integrated Natural Ventilation

With natural ventilation integrated with a Building Management System (BMS), the ventilation becomes secondary system, completely controlled by BMS.  With this system, it is possible to integrate air conditioning, central heating and similar mechanically operated systems.

Smoke Ventilation

Smoke ventilation is a life-saving feature, with up to 90% of deaths from fire being caused by smoke.  Smoke and combustion gases rise up towards the ceiling, making it the logical solution to use high-level opening windows as a means to ventilate the affected area, enabling all building dwellers to evacuate safely.

Window Control Systems has been an NZ provider of smoke ventilation solutions for more than 20 years, building on the experience of D+H Mechatronic.

Window Control Systems offers a wide range of fire rated window actuators. Fire rating for window actuators is specified by the length of time they can continue operating at a certain temperature level.  All D+H fire rated actuators are capable of operating for at least 30 minutes at temperature of 300°C, providing time for evacuation. Actuators also have high-speed function for a fast window opening in the event of fire.
