Halton - Design - Wellbeing

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

 

Reference: Main Library at University of Manchester

Halton passive chilled beams and low velocity displacement diffusers were used in University of Manchester's new Main Library to create an energy efficient and pleasant studying and working atmosphere.

Halton Multiservice Passive Beams, complete with built-in lighting that have Prismatic lens diffusers, is used in the interior of the building. Additionally, also non-beam lightning was used to create the required 350Lux light level.

Primary air is introduced via black painted Halton AFE type face plate Low Velocity Displacement Diffusers (nominal size 500 x 600, each supplying approximately 60l/s) around the perimeter.

There are radiator panels installed between the LVDV diffusers, which are behind the decorative facade in front of the LVDV units for the colder months. The radiators are designed to protect the fabric of the building and for start up for the areas that are not operating 24hrs.

Halton the Kiwi

halton-the-kiwiHalton is a Great Spotted Kiwi, the largest breed of these nocturnal and flightless birds only found in New Zealand. The chick can be expected to grow to be 45-50 cm tall and weigh up to 3 kg. Great Spotted Kiwis are found only on New Zealand's South Island, and their numbers are declining due to stoats, rats etc. killing many young Kiwis. It is estimated that 95 % of Kiwis born in the wild are killed in their first year. This makes all breeds of Kiwi highly endangered.

Halton (or the egg) was collected by the Department of Conservation in the Hawdon Valley, 2 hours away from Christchurch. When the chick is old enough, it will be returned back to the region.

Halton, whose parents are Bonny and Clyde, hatched at the New Zealand Conservation Trust's Kiwi incubation facility, housed at the Willowbank Wildlife Reserve, in Christchurch. Halton hatched on February 24th, and has been growing well.

In late March Halton joined other juvenile Kiwis in a special predator free area. After reaching the weight of 1 kg, Halton will be big enough and strong enough to fight off predators. He will then be transported to the land of his/her parents deep in the New Zealand bush.

Whether Halton is a girl or a boy, remains a mystery for a bit longer as female and male kiwis are indistinguishable. When the bird is older, a DNA test will be done to determine its sex.

The NZCT is very grateful to Halton Oy for its continuing support in Kiwi conservation. Halton Oy makes a yearly donation to the trust enabling the incubation facility's continued operation and saving another generation of kiwis.

Halton announces updated CSW beam

csw-halton_ravenscroft_updatedThe Halton CSW family of chilled beams based on swirl jet air supply has expanded. The latest solution in this range enables automatic adjustment of the supply air flow as necessary to ensure energy-efficient air conditioning and draught-free conditions. The product is also suitable for exhaust applications, enabling a uniform appearance for all terminals installed within a given room.

Chilled beams usually distribute air in two or, at maximum, four directions. Operation with the Halton CSW active chilled beam is based on a swirl jet air supply that distributes air to the room space by utilising a swirling flow action, guaranteeing a comfortable and draught-free indoor climate.

The Halton CSW introduces a new 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. This new feature makes it easier to implement demand-based air conditioning either in the construction stage or in a finished building without the need to change the product.

csw-halton_ravenscroft_updated2Demand-based control of air conditioning improves the building's energy-efficiency. Efficient mixing ventilation ensures a comfortable indoor climate, no matter the season. The Halton CSW product family is an ideal indoor climate solution for various kinds of buildings.

The range features supply and exhaust units for both variable- and constant-air-flow solutions. All product variants have uniform appearance, contributing to the aesthetic quality of office spaces.
