Highly reliable, low maintenance, environmentally friendly refrigeration dryers for volume flows up to 351 m³/min and dew points between +5°C and +10°C
Large industries vary considerably in nature, but they all share a common feature: they demand absolute reliability, 24 hours a day, 365 days a year. The cost of even a single day of lost production, or the risk of any damage to either the operation process or finished goods, could have extremely costly consequences. Parker Hiross’ Quasar refrigeration dryers, born from the know-how provided by the world’s premium large dryer manufacturer, has been specifically designed to cater for these stringent needs.
Beyond this Quasar also features numerous novel features offering significant customer benefits. Quasar takes the unique trend setting concepts first introduced on the Parker Hiross Large Expansion Dryer, and redefines them, moving Quasar even further ahead of traditional large refrigeration dryer concepts. When total reliability and complete satisfaction are top of the list, Quasar is the answer.
Sophisticated Design
The Quasar refrigeration dryer’s sophisticated design solutions lead to real advantages for the user. Quasar’s heat exchanger takes the innovative patented design pioneered in Parker Hiross’ LED, and takes it one step further. The single vessel configuration is now even more compact, further saving valuable factory space. The simplified air circuit reduces the number of welds to a minimum, for improved longevity and reliability. The implementation of quality materials, specifically treated, ensure Quasar withstands even the most rigorous industrial conditions. A combination of top dew point performance levels and minimal air pressure drops are obtained thanks to generous dimensioning, minimal air turns and performance enhancing “trifoglio” tube inserts.
Sophisticated Control
Quasar features an advanced microprocessor control as standard. The dew point is continuously digitally displayed. All functions are fully programmable, giving the user full control over dryer operation. A working hour counter and programmable service interval monitoring facility simplify maintenance scheduling. A status report lists the 20 most recent occurrences, whilst a secondary report memorises all sensor readings at alarm intervention, for easy fault diagnosis. The comprehensive set of alarms can be user-programmed, and on intervention they provide easily understandable written text messages. A general alarm volt free contact is also supplied. The microprocessor can furthermore be programmed in several languages, ensuring that Quasar really does speak your language.
Product Features
All models feature a low pressure drop pre-filter on the air inlet. This feature keeps the heat-exchanger clean and reduces maintenance requirements.
The oversized demister separator offers an exceptional condensate removal rate with lowest pressure drops. Unlike centrifugal systems, the demister works equally well at partial air flow conditions, ensuring the dew point is maintained under all conditions.
The standard shell-&-tube water-cooled condenser ensures extremely low water side pressure drops and requires minimal maintenance. Air-cooled versions are also available.
Quasar’s innovative tandem scroll compressors (standard up to 225m³/min.) offer numerous real customer benefits, including: significantly reduced power consumption; real 50% energy savings at partial load as one compressor switches off (unlike typical solutions); longer compressor life; elimination of the need to pre-heat the dryer; no risk of compressor damage caused by liquid returns; full stand-by facility as one compressor still runs if the other shuts down.
