Enlarged pit furnace accommodates today’s larger components  Developments in renewable energy, mining and quarrying, oil exploration, marine and other applications have led to significant increases in the size of power transmission components like gears, shafts, pinions and bearings, to handle greater productivity demands. As these large components are exposed to severe duty cycles, there is renewed emphasis on the heat treating methods needed to enhance their wear resistance and strength properties.  Estimated by industry sources to represent around 10 per cent of component manufacturing costs, heat treatment modifies the microstructure of metallic materials, influencing mechanical characteristics like strength, ductility, toughness, hardness and wear resistance. Anticipating growing customer demand for processing larger gears, shafts and other components, sub-contract heat treatment specialist Keighley Laboratories of West Yorkshire has enlarged the size of one of its largest pit furnaces, increasing dimensions to 1110mm working diameter and almost 1800mm maximum length, in the process gaining 30 per cent in overall capacity. At the same time, it has upgraded the lifting capacity of its overhead crane, which services all seven pit furnaces, a salt bath and tempering equipment, to 3.0 tonnes maximum lift.  “This has opened up a new market for us amongst engineering companies and OEMs, who are looking to heat treat larger components” says Divisional Commercial Director, Michael Emmott.  Further enquiries to Keighley Laboratories Ltd, Croft House, South Street, Keighley BD21 1EG Tel: 01535 664211 E-mail: memmott@keighleylabs.co.uk  Web: www.keighleylabs.co.uk  water treatment solutions heat transfer & energy SPIRAX SARCO LAUNCHES HIGH TURNDOWN, PLUG-AND-PLAY DESUPERHEATERS Spirax Sarco has launched the industry’s most comprehensive range of desuperheaters for precise control and efficient heat transfer when cooling superheated steam. Featuring a high turndown of up to 50:1, the desuperheaters are suitable for a wide range of applications and increase process efficiency by allowing waste and residual heat to be recovered and recycled. They also protect process plant from damage caused by overheating. Manufactured at Spirax Sarco’s UK factory, the desuperheaters are supplied as ready-to-install engineered systems, fully assembled with all the required valves, pumps, steam traps, controls and other ancillary equipment, saving installation time and project costs. Each desuperheater is tailored to the application for the highest efficiency in a wide range of industries, including food and beverage, chemical, pharmaceutical, processing, power generation and oil and petrochemicals. Desuperheaters reduce the temperature of superheated process steam by introducing finely atomized cooling water droplets into the steam flow. To be effective, the droplets must remain suspended in the downstream pipework for as long as possible, otherwise ‘water droplet fall-out’ occurs reducing efficiency and causing corrosion. Spirax Sarco desuperheaters eliminate water droplet fallout and ensure reliable, efficient energy transfer. The range comprises four designs. • The Spray Nozzle Desuperheater is inserted into the steam line and is easily retrofitted into existing pipes. It is particularly cost-effective for large diameter pipes. • The Spray Desuperheater is a complete pipeline unit incorporating spray nozzle technology with an integral thermal pipeline sleeve. Superheated steam circulates around the sleeve assisting the evaporation of atomised water, eliminating water droplet fall out. • Both types of spray desuperheater are suitable for steady loads, since they offer a maximum turndown of 5:1. Where tighter control of the downstream temperature is needed in processes with higher load fluctuations, a Venturi or steam atomising type desuperheater with a larger steam turndown could be a better option. • The Venturi Type uses a “double mix” operation combined with increased turbulence for more efficient steam cooling. With a turndown of up to 10:1, it suits most general applications. • The 50:1 turndown of the Steam Atomising desuperheater suits applications where the load varies considerably. A secondary, high-pressure steam supply is used to atomise the cooling water entering the superheated steam. Spray Type, Venturi and Steam Atomising desuperheaters can be installed vertically or horizontally to suit the application. The desuperheaters have no moving parts making them virtually maintenance free and highly reliable to support high productivity.

Moody Heat Exchangers know that quick and easy access to test certificates and service reports is important to customers in the hygienic processing industries when faced with internal and external quality audits. This secure, web-based portal allows customers to log on using a secure password to access vital quality information about their plate heat exchangers. Moody Heat Exchangers integrity test plate heat exchangers and pasteurisers using the PasTest2000 system which accurately detects plate cracks and holes which could cause product contamination. The PasTest2000 testing system has been tested by CampdenBRI, the leading independent food and drink research organisation. Moody Heat Exchangers are a one-stop shop for both testing and servicing of plate heat exchangers, operating the UK’s most modern plate heat exchanger service centre in Retford, Notts. Gaskets and plates are supplied for all known brands of plate heat exchangers including Alfa Laval, APV, Arsopi, Fischer, GEA, Pasilac, Schmidt, Sondex, Swep, Tetra Pak, Tranter, and Vicarb.

REMOX is a membrane degasser which removes carbon dioxide and oxygen from water. The first membrane degasser available on the rental market, REMOX is housed in a fully air-conditioned standard 40ft container complete with all necessary compressed air, nitrogen and vacuum equipment. With two streams of membrane modules, REMOX can treat up to 100m3/h of water to less than 0.3mg/l dissolved carbon dioxide and up to 75m3/h to less than 0.01mg/l dissolved oxygen. Among the many applications for REMOX are deaeration of boiler feedwater to reduce corrosion, degassing of semiconductor rinse water to reduce wafer surface defects and to improve the shelf life and taste of food and beverage products. Additionally, ion exchange deionisation and continuous electrodeionisation processes operate much more efficiently if dissolved carbon dioxide is removed upstream. Aquamove REMOX removes dissolved gases without any chemical addition or waste water, providing safe operation. Complete with automatic monitoring, the AquamoveTM  team can monitor the system data and performance, and control the plant. So the supply is maintained and optimised remotely, with total operational security. Visit www.aquamove.co.uk to find out more about REMOX and other mobile water treatment solutions for short or long term hire.
