A resin drying system said to offer substantial increases in productivity and reductions in energy cost, maintenance, and reject rates is now available from Maguire Europe.
The NovaDrier is based on patented technology that eliminates moving parts and bypasses traditional moisture removal techniques, such as the use of desiccants, in favour of flowing compressed air through an adsorption membrane. Maguire claims it consumes up to 75 per cent less air than other systems using compressed air. Savings in energy are achieved in comparison with desiccant systems, since there is no desiccant to be regenerated.
Paul Edmondson, general manager of Maguire Europe, emphasises: "The moisture removing efficiency of our proprietary membrane is so great that process air at –40 degC dew point is flowing through the system in less than four minutes after start-up, and the membrane has been shown to last up to 20 years under demanding end use conditions. Another benefit is enhanced part quality, which results from consistency of process temperature and continual purging of volatiles from the process."
The NovaDrier 75 is a CE certified unit that accommodates throughputs up to 35 kg/hour. It also incorporates a hopper door with full glass viewing panel contoured to the hopper shape, and has stainless steel on all surfaces in contact with resin. Six other models cover throughput capacities ranging from 3.2-102 kg/hour. Maguire claims they are all more compact than any other dryer of comparable capacity and can be machine mounted.
The compressed air used by the NovaDrier can come from any source and need not be refrigerated or pre-dried. Other than normal hopper clean-out, the only maintenance typically required is to change two filter elements every 12 months. The primary control is a simple ‘On/Off’ switch.
