Desiccant air dryers
Two new models to the HPSA range , HPSA 70 and HPSA 100 , bring the total number of standard models to 12 with flow capacity from 75 to 1130scfm .
Hi-line Industries , a UK manufacturer of compressed air purification equipment , offers a fully featured range of desiccant air dryers . The company ’ s series of HPSA heat-less dryers includes new standard models , the recently launched HPSA-CT ( Carbon Tower ) version plus the bespoke HP-HPSA ( High- Pressure ) model . They are designed to meet the needs of manufacturers wanting dry , clean compressed air or nitrogen in various applications .
The Hi-line HPSA ( Heat-less Pressure Swing Adsorption ) series of desiccant dryers are ‘ plug and play ’ units with digital control panels that are skid-mounted with their own filtration package ( pre- and post-filtration ). All standard HPSA dryers use Dri-Zorb 27 desiccant media that delivers constant low dewpoints while consuming low quantities of regeneration air .
Hi-line is constantly looking to expand its portfolio , recently enhancing the HPSA range with two smaller capacity models . The new HPSA 70 and HPSA 100 bring the total number of standard models to 12 , with flow
capacity ranging from 75 to 1130scfm ( larger heat-less dryers are available , if required ).
“ Another recent introduction to the range is the HPSA-CT ( Carbon Tower ), a three-stage dryer with the Carbon Tower added after the adsorption dryer . Clean , dry air passes through the Carbon Tower and absorbs gases and aerosols depending upon requirements and the zeolites selected . This capability makes the HPSA-CT flexible and suitable for use in many specific applications . The Hi-line HPSA-CT features pre-filtration , sub-micron oil removal and safety valves as standard , as well as an after-filter for particulate removal . A total of 12 standard HPSA-CT models are available with flow capacity from 80 to 1130scfm . Larger HPSA-CT dryers are available upon request ,” said the manufacturer .
Hi-line can also now offer its bespoke HP- HPSA ( High Pressure ) heat-less dryer . This model features the same HPSA technology , running at high pressure . Control air is at 7 bar , but with elevated pressures up to 450- bar for specific applications .
“ Every HPSA model in the extensive Hi-line range is a fully automatic , IP65- rated , self-contained unit featuring HDC1 digital dewpoint controller , stainless steel pipework , independent switching valves , exhaust silencers and a one-year warranty on parts and labour . Options include our AEMS Automatic Energy Management System , dewpoint to -70 ° C and automatic start / stop control ,” added the manufacturer . n
Busbars in different geometries and lengths .

Stamping and forming
Busbars made of copper or aluminium are forming tools , the units with the punches are crucial components in high-performance arranged in a circle around the forming centre . battery systems and complete power
The raw material width corresponds to the part distribution . Otto Bihler Maschinenfabrik offers width . For busbars , which are made of 4mmthick pure copper , this saves up to 50 per cent automation solutions for the mass production of these E-components . in material costs compared to production with
“ Users benefit from material savings of up wide strip , said Bihler . to 50 per cent , flexible production with a wide The other half of the busbars is produced range of variants and high productivity ,” it told with the LEANTOOL linear system due to its ISMR . component length and the additional forming A leading global automotive supplier now steps . For each of the variants , three L250 produces large numbers of busbar variants on forming modules and two cutting frames are a single Bihler GRM-NC servo stamping and available in the two 400kN servo presses . forming machine , the manufacturer explained . “ Changeover times from one variant to It is equipped with six NC units and two 400kN another are one to one-and-a-half hours . presses , which are used individually or in Together with the two servo presses , process combination . lengths of over 2,000mm can be achieved .
Due to their geometries and dimensions , Linear production saves up to 30 per cent of half of the busbar variants are manufactured material , as only one carrier strip is required ,” using the LEANTOOL radial system . In these explained the manufacturer .
The integrated LEANTOOL tooling system aims to significantly shorten the design and implementation times for new tools . This is due to the high proportion of standard parts in the highly standardised forming tools of up to 70 per cent as well as Bihler machine technology which enables movements from three sides .
“ In addition , the Bihlerplanning WebApp supports planners and designers as early as the component planning , process determination and quotation preparation stages , as well as in the design of LEANTOOL radial and linear tools . All of this shortens time-to-market margins enormously . Users are therefore ideally equipped to meet the requirements of the future market of e-mobility and to play a significant role in shaping it with their own innovations ,” concluded the manufacturer . n
