Case Studies 39 Toshiba takes new aircon into Woodlands
THE FIRST UK installation of Toshiba’s new high efficiency Digital Inverter 4 range of air conditioning units has been carried out by Metainy Air Conditioning . The long-standing Toshiba accredited installer has installed the new heat pump-based system at its headquarters at Woodlands Business Park, Maidenhead, as part of an upgrade of the existing system serving the company’s project design and administration offices.
The installation uses a ducted split system based on two 2.5kW Toshiba DI 4 high performance units, supplying cooled and heated air through the ceiling void to outlet grilles above the main working area. The new units are an important addition to Toshiba’s range, which now spans from 1hp (2.5kW) through to 10hp (25kW) within the Digital Inverter range and offers models across the spectrum in this popular sector of the market.
Offering exceptional efficiency and fully compliant with the ErP Directive (Lot10) threshold for 2015, they have a sector-leading operating range, delivering cooling from -15°C up to 46°C and able to provide heating in ambient conditions as low as -15°C, eclipsing industry rivals by a significant margin, it is claimed. The most efficient combinations can deliver a SEER number as high as 6.1 and are rated at A++ for energy performance. Efficiency is helped by the use of Toshiba’s power-save function, which enables the user to set the degree of performance covered, between 50% and 100%, in 1% increments. The new models allow small capacity systems to be fully integrated with
VRF systems and BMS controls using an interface – which are not required on wall mounted systems – and are compatible will the range of light commercial and commercial control options. Compatibility with BMS controls was one of the key reasons Metainy opted for the new Toshiba Digital Inverter (DI) units.
Metainy director, Mac Baker, said: “The new DI systems are designed to dovetail with the BMS we already have installed on site, which makes it easy to set them up and quickly integrate with the rest of the system.”
He added: “They are also excellent for maintaining comfort conditions due to the fine control, and a real step forward in this sector of the market.”
Metainy is one of Toshiba’s longest serving Accredited Installers, with some 30 years’ experience of applying and servicing Toshiba equipment.
Mac Baker said: “Toshiba products are reliable and superbly engineered, which means a lot when one call back can wipe- out the profit on a project. The back-up and technical support is also first-class - we can count on Toshiba to give us the information and support when we need it. Overall, it’s a great product, supported by a great team.”
The company recently won two projects with a national high street chemist, which has specified the new Toshiba DI air conditioning equipment for use in its stores.

CROWN PACKAGING IN Carlisle enjoys huge demand from consumer marketing companies around the world for its colourful food and beverage cans. In fact demand has been so great that the specialist hydraulics on the can making machinery were running at dangerously high temperatures, leading to the danger of costly breakdowns. Three companies were contacted by Crown to solve this problem including Thorite, the UK’s biggest distributor of pneumatic products and process systems, with a brief to supply and install advanced, energy-efficient equipment. Thorite carried out site surveys and developed a solution centred on two Parker Adiabatic Air Blast water coolers to supply cooling water to the hydraulics of the can making equipment. These coolers consist of copper tube and aluminium magnesium fin coil blocks, direct drive axial fansets, galvanised steel casings, stainless steel

space 10.5m long by 3.5m wide. This meant there was insufficient room to site them inside the plant so a large mobile crane was used to lift them on to the roof. Once in place Thorite also provided all ancillary requirements including fabrication, pipework, machinery supports and pipe bridges.
collection trays, local fan isolators and variable fan controls as standard. Adiabatic cooling is achieved by mains water distributed over an evaporative cooling media through which incoming air passes. The cooled dry air then passes onto a coil for further cooling. This method prolongs the coil life by reducing coil fouling and negates the need for expensive mains water treatment. Thorite project managed this major capital equipment project from inception to completion. Each of the coolers weighed 3185kg and occupied a floor
Ian Connelly, Crown Packaging’s technical manager, had no hesitation in selecting Thorite to supply and install the equipment and said: “Thorite was one of three candidates for this project and based on their price and professional presentation was awarded the contract. Our dealings with them have provided a good all-round experience with no major concerns and the equipment is performing precisely as promised. Although it is still early days I am confident that the coolers will help safeguard and boost our output whilst contributing to our on-going drive on energy reduction.”
