The Hi-line range of HPSA (heatless pressure swing adsorption) desiccant dryers are now all equipped as standard with their new HDC-1 digital controller, providing a digital dewpoint display. In addition the range of products has been extended to cover air flow capacities from 230 to 17,000 Nm3/h as well as accommodating operating pressures up to 40 bar, with standard units rated at 11 bar. All product upgrades have been incorporated without increasing unit prices, to ensure that they still represent excellent value for money combined with high performance and increased operating capacities.

All the dryer models are fitted with safety relief valves as standard, while generous desiccant beds save energy as the stand-by condition on dewpoint control is significantly longer. Operation is simple owing to limited moving parts being utilised with positively driven ball valve action, with no shuttle valves incorporated.

All models are built in Burton-on-Trent at the Hi-line production facility. The pressure valves are also of UK manufacture, and supplied with full vessel documentation and CE certification. The dryer products are skid mounted, incorporating both pre and after filtration, with all associated pipework being manufactured in stainless steel.
