Ravenscroft New Zealand

Halton's care for the environment extends beyond indoor air quality. For several years Halton has supported the New Zealand Conservation Trust in its work to save the Kiwi by incubating and raising the Kiwi chicks in safe, predator free areas until they are old enough to fend for themselves.

As a sign of their appreciation the NZCT has named one of this years chicks Halton.

Halton is a Great Spotted Kiwi, originally from the Hawdon Valley, where the bird will return as an adult.

Halton announces updated CSW chilled beam models 

Halton has unveiled new models of their ground breaking CSW swirl jet chilled beam.

Halton's round CSW beams are designed to guarantee a comfortable and draught-free indoor climate. The newest CSW beams feature automatic adjustment of supply air flow on the basis of the room air temperature or CO2 content, for a substantial increase in energy-efficiency. Read more ...

The ARBS Exhibition became an important part of  our activities in Australia, thanks to  an incredible interest from Engineers, Designers and Architects.  The display "Green and Gold" Active Chilled Beam was a hit along with the unique Halton "Swirl Comfort Unit", and our new high capacity Passive Chilled Beam.  The latter unit is the newest development of Halton's CPT type beams.  This technology has been a great success around the world, including the installation at the Melbourne Convention Centre - a recent project led by the WSP team.

As we had anticipated Mechanical Contractors were asking lots of questions about the benefits of Ravenscroft Circular  Fire Dampers for quick installation in to concrete and plasterboard walls.  If you haven't seen these products yet, please refer to the video on this website.

Congratulations to our winner of  the "Fine Wine Award", Mr William Chiu from GCI Chemicals (Australia) Pty Ltd.

This Halton Indoor movie showcases their chilled beam and displacement products, many of them custom-made, and how they blend into the architectural design.

Several international studies have found that indoor air quality in schools remains poor. This causes an increase in symptoms and illness, shortens attention span, while good air quality can enhance children’s concentration and also teachers’ productivity. The most common indoor climate problems are inadequate ventilation and thermal comfort.

In a recent article on indoor air quality in classrooms Panu Mustakallio and Risto Kosonen compared different air distribution methods and their effects on air quality in the classroom using a fullscale laboratory test to measure their performance. In their article, “Effect of Air Distribution Methods on Classroom Air Quality” originally published at Indoor Air 2011 conference, Mustakallio and Kosonen found that the average indoor air quality in the occupied zone was best with displacement ventilation, which also produced very good thermal conditions. For best results they recommend placing diffusers in all four corners of the classroom.

Displacement ventilation is also incredibly energy efficient, which makes it an excellent choice for ventilation in classrooms.
