The dryers’ efficiency is further improved by using a blower/fan, rather than compressed air, for desiccant regeneration.
The dryers also include an automatic energy management system (AEMS) controller that features a zero loss heater blower programme and undertakes constant monitoring and analysis of the dryer load parameters, while making necessary adjustments to the dryer cycle to ensure continuous maximum efficiency.
This maintains the lowest possible running costs coupled with regeneration at the lowest energy tariff while also ensuring that the compressed air inlet conditions are matched to the dewpoint required, the company says.
The AEMS controller comes as a factory fitted attachment with the Hi-line HBP-TS series dryers, but can also be supplied for retrofitting to any make of existing ‘dumb’ dryer.
These dryers achieve dewpoints of –70° PDP without loss of compressed air and are available with flow rates from 10 up to 10,000scfm. They feature thermally efficient, fully insulated vessels, with heaters and heat exchangers. Waste heat utilisation from steam, oil or compression can be optionally used where available, with a fan motor also optimised for maximum use with minimum power consumption.
Stainless steel pipework is fitted as standard with independent fail-safe switching valves and full-flow LPD check valves incorporated. Pressure equalisation and heater protection systems are also provided, eliminating pressure fluctuations and maintaining safety standards.
