Compressor
MacGregor HSC screw compressor

Main features
The possible applications of HSC
screw compressors are almost
unlimited and as individual as theavailable designs.
Even the small HSC with 4 kW
motor rating has the potential of a
top performer. The design features
and advantages are consistentlyapparent in all HSC models,e.g. the integrated oil sump, theunrestrictive access to all sides
and the PROCON control system.

Product features:• 1 - Two stage suction inlet filter: the entryof foreign bodies is prevented by a cyclonic separator,
fitted with a fine pre-filter.
• 2 - Equipped for the future: different pressures areachievable via the flexibility of utilising a belt drive. Inaddition, this facilitates smooth starting, absorbing theensuing starting torques effectively.
• 3 - Drive: HSC screw compressors are manufactured
to high standards of quality. This includes the use of
IP55 tested motors, meeting Class F insulation andClass F temperature rise requirements.
• 4 - Integrated oil sump: designed to prevent theescape of used oil to the environment. A hose
supplied shortens the oil change time.
• 5 - Three-stage air/oil separation: a cyclone
separator, a gravity separator and a filter produce highair quality resulting in a residual oil content of approx.
2mg/m3• 6 - Suction control: the use of hard anodised
surfaces guarantees the highest durability and control
capability. No adjustments are required for standard
MacGregor suction regulators. If required a
proportional controller can be supplied. This provides
smooth flow adjustement for the air demand.
• 7 - External fine separator: well-proportioned fineseparator elements reduce internal pressure losses.
The elements can be changed in just seconds.
• 8 - Piping: rugged, high quality pipe and fittings,
designed and installed to enable ease of access formaintenance.
• 9 - Accessibility: all side panels are removable. Thisfeature allows unhindered access to all areas.
• 10 - Compact aluminium cooler: the composite
design unifies oil and air cooling in a single assembly.
The design enables ease of cleaning.
• 11 - Operation pressures: the rugged, modular
construction of the HSC screw compressors allows
pressures from 7.5 to 13 bar.

PROCON control
Screw compressors of the HSC series are equipped as standard withPROCON, an integrated microprocessor control system. PROCON simplifies
operation and provides many performances features. All settings can bemade conveniently on a control panel. Numerous operating modes permit
optimisation of the existing operating parameters.
An integrated diagnostic system monitors all safety-related operating conditions.
• System pre-start diagnostic checking• Service maintenance indication• Automatic start-up after power failure• On reaching the final pressure, PROCON calculates
and instigates required run-on time (saving up to 60%
of energy costs in idle operation)• The air sytem pressure sensor ensures precise control
up to the pressure required (this pressure is adjustablein increments of 0.2 bar)
• In “auto-mode” the compressor runs only on airdemand• Corrosion resistant contacts are provided forconnection to a master control system• Switchable remote and local function• Electronic base-load change-over function regulated
via second pressure band (optional)
