Fig. 1:While innovative products generally have a higher capital costs than traditional approaches, reduced labour costs can bring significant benefits. This example illustrates the installed costs of pipework using a channel system. Material costs are 8.4% higher, but labour costs are 46% lower. The overall effect is a 7% reduction in installed cost.

Where markets and technology meet

Progressive companies base their success on a sustained programme of new-product development. Anne King examines the issues in the building-services sector.

A better way of controlling stored open-and-shut case for advanced float valves

Even products for very simple tasks can have far-ranging implications.Lawrence Burns considers float valves for controlling the water level in storage tanks and the benefits to health and safety and energy consumption.

Trox pic
Steering a new course — Colt (represented by Simon O’Hea, left) and Trox (represented by David Leatherbarrow) have combined their respective expertise in fan-coil units and grilles and diffusers to offer the industry a guaranteed-performance package covering noise, thermal performance and air distribution.

Fresh thinking on fan-coil units and diffusers

The traditionally separately supplied products of fan-coil units and diffusers are now offered as a single package with guaranteed performance.

The Airovision range of air-handling units is the outcome of a 3-year development programme by Carrier Holland Heating to address cost issues and deliver a higher-specification product.

Redefining the production of air-handling units

Keeping up in a competitive market place demands periodic reviews of product ranges. We found out how Carrier Holland Heating enhanced its AHU offering and addressed costs.

Commissioning module
Ensuring that the flow to individual fan-coil units in a group (three in this case) is maintained as others close and open is a recently developed concept in commissioning modules from SAV. They can be installed in ceilings and floor voids.

The self-contained solution for commissioning fan-coil units in variable-flow water systems

Effective commissioning of chilled-water systems is vital to their efficient operation — even more so when variable-speed pumps are used. SAV has responded to the challenge with commissioning sets that make possible the balancing of several fan-coil units from one point.

Split air-conditioning systems move towards greater efficiency

Most people must be noticing that R410A split-system air conditioning is more efficient than previous systems. But the change is not just due to the refrigerant.

Designed for long life in arduous conditions — the Workhorse fan range from VES Andover.

VES fans designed to go on and on

VES Andover has developed a range of fans designed for reliability and to work continuously in arduous environments. They have a life expectancy for bearings in excess of 200 000 h with continuous running temperatures up to 150°C.

Any throw you like — the nozzles in Colman’s N Series of diffusers can be individually adjusted.

Innovation drives product success

The design features of Colmans N Series of nozzle diffusers are said to be a major factor in the products success.

AgCu water treatment
Water disinfection for long periods of time can be achieved using copper/silver units from KK Water Purification.

Advanced water disinfection

The controlled use of copper and silver ions to disinfect water is said by KK Water Purification to avoid the biodegrading problems associated with some biocides, to that they become food for micro-organisms. Disinfection is ensured for long periods of time. Ultra-violet disinfection has similar benefits.

Duct reducer
Innovation from Lindab — the reducer that also reduces pressure loss.

Reducing ductwork losses

A duct reducer that also reduces pressure drop has been developed by Lindab. The reducer has a bell-shaped design and is available in diameters from 100 to 250 mm.

Another giant leap for inverter drives — Mitsubishi Electric’s F700 achieves instant optimisation.

New-generation drives save even more energy

A new series of variable-speed drives from Mitsubishi Electric is said to set new benchmarks for energy saving through the development of improved power circuits, coupled with the the advanced processing power of the latest electronics to provide enhanced power-control strategies. They are intended particularly for pumps and fans.

Plantation place
Innovation in commissioning — Yorkshire Fittings’ Venturi commissioning valves have been used in sizes up to 250 mm in this project in the City of london.

Innovation in commissioning valves

Faster and more accurate commissioning for a major project in the City of London has been achieved using Venturi commissioning valves from Yorkshire Fittings. David Hearne, commercial manager for valves, says, The Yorkshire Venturi is the first innovative static commissioning product to enter the market in many years.
