Reznor downflow units strike a ‘cord’ for yarn manufacturer
Richards of Aberdeen, a leading manufacturer of high quality yarn for carpet making, has installed ‘third generation’ heating from Reznor at its refurbished premises. The heaters achieve draught-free comfort conditions with very economical operation.
When Richards took over an old bakery in the city, the existing heating system was adapted to the warm conditions generated by bread making and was therefore inadequate for the building’s new purpose.
The 9,300m building consists of three interconnected sheds that now house four production lines, where loose fibre (called sliver) is spun into continuous yarn and wound on to cones.
It is important to Richards’ quality standards and the health and safety of employees to avoid generating airborne fibre and dust particles within the factory. A draught-free environment was a pre-requisite of the heating system.
Engineering consultants NIFES Group recommended a Reznor warm air heating solution using the new V3 downflow unit. A total of 30 V3 heaters were suspended in the roof apex at 6.5m, well clear of the production lines. The downflow units effectively direct warm air to where it is needed in the lowest two metres of the building, without creating air movement where the fibres are being processed. The heaters were installed by project heating engineers Sparks Mechanical Services of Aberdeen.
The Reznor heaters were specified for their economy, ease of installation and ability to achieve good distribution over a large area. Each unit can be controlled separately for maximum flexibility. Roddy Duncan of Richards comments: “The heaters maintain a constant 20°C comfort temperature within the factory and answer our need to minimise loose fibres and dust.”
MOTs in the warmth of Reznor
Customers calling at Guildford Borough Council’s service and maintenance depot, can take their vehicles for an MOT in comfort now, after four Reznor heaters were installed in its Woking Road Depot.
The 200m² building is divided into three separate work areas. In one, lawnmowers and plant are maintained and refurbished. In the second, heavy goods vehicles are inspected and prepared for MOT inspections. Finally, in the third area, public MOT testing and the inspection and testing of taxis and private hire vehicles are carried out.
The depot was fitted with four Reznor heaters in January 2003. Free-standing cabinet heaters were installed in the MOT building and the heavy goods area, while suspended gas-fired units were positioned in the lawnmower workshop. The heaters replaced temporary gas heaters which were based in the lawnmower workshop and heated only half the space, making them both inefficient and expensive to run.
The building is a large space with high ceilings. To make the most of the heaters, recirculation fans have been fitted in the roof to ensure that all the heat is distributed evenly throughout the building and used in the most effective way possible.
Eight full time employees are based in the warehouse and there are people and vehicles coming and going throughout the day. It is important to maintain a constant internal temperature of 18ºC and ensure that the heat doesn’t escape through the doors. Before the new heaters were installed, the team was keen to get the loading bay doors open and closed as quickly as possible, but the new heaters can maintain a consistent heat regardless of the external temperature.
Derek Trawber, Administration Manager for the Service and Maintenance Depot says, ‘We are very happy with our new heaters. Now we’ve had them installed, the difference is clear and it’s great to have a more comfortable, stable working environment. All the solutions to the heat loss problems we were experiencing have been very effective in practical terms, allowing us to make full use of the heat provided, which also enables us to save money.’
Reznor ‘hothouses’ Halls Garden Products
The conversion of the old Kimberly Clark paper factory at Aylesford, Kent to a manufacturing facility for extruded aluminium greenhouse frames called for a new energy efficiency heating system that would maintain constant comfort temperatures for production line workers.
Halls Garden Products took over the building in late 2002, refurbishing the premises to include a 2000m² production area and adjoining storage facility. However, at the time of designing the heating system, there was no usable wall space down one side of the building, and limited gas supply to the premises.
Reznor designed a system that positioned seven C4000 compact gas-fired warm air heaters, each with an output of 72kW, along one 80m wall of the production area. To create even heat coverage, four Maximisor recirculation fans were installed in the roof space. These effectively redistribute warm air to maintain a warm working atmosphere for employees.
The configuration allowed the heater flues to pass through the wall and terminate there, thus avoiding complicated gas supply runs as well unnecessarily penetrating the new roof. Bill Lynch, of Hadene Building Services Chatham, who installed the system, comments: “By positioning the heaters along one wall, we were able to minimise disruption to the existing gas pipes, making installation of the heating system much easier.”
Norwich Union and Reznor - together they're warmer
Norwich Union, the UK's largest insurer, and Reznor, the UK's leading supplier of bespoke warm air heating systems, have teamed up to ensure life for employees at Norwich Union/Aviva Group UK’s main literature storage facility is comfortable all year round.
Ensuring even distribution of heat between the pallet racking and above the mezzanine floor required the precise positioning of warm air unit heaters around the building. Eleven C4074 compact heaters were wall mounted between racks just below roof level. The warm air is redistributed throughout the main storage area by 20 roof-mounted Maximisor recirculation fans.
A ducted warm air system, powered by five Euro T2236 units, maintains constant temperatures of 210C for personnel working at mezzanine floor level.
This system also provides warmth to high bay areas
The Reznor system was recommended by Roberts & Partners of Glasgow, retained consultants for Norwich Union, and installed by M & E contractor ABB Building Technologies Ltd of Ipswich.
John Shannon of Roberts & Partners comments: 'The system effectively achieves total heat distribution around the racking and working areas of the building. Reznor warm air units are renowned for good quality and longevity - I had no hesitation in specifying them for this application.’
Prism Leisure installs Reznor V3 warm air heaters to revolutionise heating efficiency
Prism Leisure – the UK’s leading wholesaler and worldwide distributor of CDs, cassettes, computer games, videos and DVDs – is one of the first companies in the country to install the revolutionary V3 warm air unit heater from Reznor. The new lightweight gas-fired heater offers exceptionally high performance while saving energy through lower fuel consumption.
In late 2002, Prism Leisure expanded its operation with an additional high-bay warehouse close to its headquarters premises in Enfield, Middlesex. The 1,500m² building has a roof height of over seven metres in the main storage area. A mezzanine floor, occupying one side of the premises, created an additional challenge to even heat distribution within the building.
Four Reznor V3 warm air unit heaters were installed by First Call Services UK Ltd of Enfield. Three 35kW output units were suspended within the roof space of the main storage area, and one smaller 20kW output unit was positioned beneath the mezzanine floor.
The V3 is the first radically new product to be launched in the warm air market for many years and demonstrates Reznor’s pioneering approach to technology development in the sector. Its revolutionary design incorporates a single, self-aligning burner that provides optimum combustion. The lightweight, low profile titanium stabilised heat exchanger has a unique serpentine shape that produces excellent air flows with low resistance for faster heat response and improved comfort levels. All heaters in the V3 range are on the government’s Energy Technology List, and therefore may qualify for Enhanced Capital Allowances.
The very high efficiency of the V3 heaters means that total gas input is relatively low. As a result, the existing gas supply did not need to be uprated, avoiding cost, delays and disruption. As an additional economy measure and to further minimise running costs, Reznor Maximisor recirculation fans were installed at high level to redistribute warm air to maintain a warm environment throughout the building.
The heaters are controlled by an Energymisor Mk111 control panel. A zoned system enables Prism Leisure to operate only those heaters which are required at any one time.
Ivor Young of Prism Leisure comments: “The V3 is an exceptionally high performance heater, and we expect to see a return on our investment through energy savings in a very short time. Its versatility in being capable of vertical or horizontal installation made it ideal for providing even heat coverage where there is high level racking and a mezzanine floor.”
DELRAC FITS REZNOR BURNERS FOR
DEBENHAMS MEGA-STORE
The new Debenhams in the refurbished Bullring in Birmingham is the first of the retail group’s Twenty10 stores – a pioneering new look for the shop interior with a whole new approach to shopfitting and lighting.
Contributing to the ambience of the new store is a warm air heating system that maintains comfort conditions for staff and customers at all times, yet operates very economically.
The department store is one of Debenhams largest, with around 21,400m² of retail and back of house space, ranged over four trading floors. Every floor is equipped with three Delrac air handling units, each with an output of 120kW. Housed within each AHU are two Reznor gas-fired RHC heat exchangers. Warm air is ducted on to the shop floor and distributed through discreet grilles, maintaining even heat coverage and constant comfort temperatures of between 22 and 24°C.
The heating system was designed by Grant Gower of Cudd Bentley Associates, engineering consultants to Debenhams. “The Reznor heat exchangers were selected to complement Delrac AHUs because of their efficiency. They offer an economical solution to heating an extremely large store.”
