Screw air compressors
Continuous-duty compressed air for factories, mills and process plants. Single stage and two stage, fixed speed and variable speed, designed for Indian summers. VIMCO sizes, supplies, installs and services them.

How steady is your air demand? Running patternA starting point. Our engineer confirms it against your measured demand.
Compare the ranges
| CTSD fixed speed | VSDx variable speed | CTS II two stage | |
|---|---|---|---|
| Compression | Single stage | Single stage | Two stage with inter-stage cooling |
| Speed control | Fixed, star-delta start | Variable frequency drive with IPM motor | Fixed or variable (VFD+) |
| Strength | Simple, proven, lowest starting cost | Matches output to demand, stable pressure, low starting current | Up to 15% energy saving over single stage, per Comptech |
| Best for | Steady demand near full load | Fluctuating demand | Continuous duty where energy cost dominates |

What is inside
Design choices that suit Indian plants
The features Comptech builds into its screw range, and why they matter on your floor.
Airend
Precision rotors turning at low RPM for efficient air flow and long life. 1:1 direct drive removes belt and gear losses.
Low maintenance, no transmission loss
IPM motor, VSDx
Efficiency up to 94.5 percent, no bearings on the motor side, no gears or belts. Comptech reports about 20 percent lower specific energy than its earlier VSD models.
Variable speed models
Two stage compression
A lower compression ratio per stage with inter-stage cooling reduces leakage and energy use.
CTS II series
Cold-zone panel and PLC
Starter and electricals sit in the cold air stream. The PLC shows pressure, temperature and current, and runs fan control without thermostats.
Fewer electrical faults
Big coolers
Oversized air and oil coolers sized for hot climates raise durability and keep the machine within temperature on peak summer days.
Better cooling, longer lifeOil separation
Oil is thrown out by centrifugal force first, then caught by the separator element, so very little oil leaves with the air.
Lowest oil carryoverDusty-air intake
A large two-stage suction filter with pre-filters keeps dust out of the compressor.
Lowest dust intakePiping
Seamless, long-life pipework and quality connections remove a common source of oil leaks.
No oil leakageConfigurations
Floor-mounted, or ready on a tank with a dryer
The same compressor can arrive as a complete package.
Floor-mounted
The standard layout for plant rooms, with receiver and dryer plumbed separately for best flexibility.
Tank-mounted with dryer
Compressor, air receiver and refrigerated dryer on one base. Compact and quick to install for smaller duties.
Two stage cabinet
The CTS II range in its enclosed cabinet, built for continuous duty.

What does your compressed air cost to run?
Enter your compressor's size and hours. Then test what a saving of a few percent is worth each year.
Energy cost and saving
Use the motor rating and your typical load. The saving figure is yours to set; Comptech states up to 15 percent for two stage over single stage.
Approximate. Uses motor rating × load as input power, which ignores motor losses. Over its life, electricity is usually the largest cost of a compressor.
Sizing
What we need to size your compressor
A few numbers let our engineer propose the right machine, and flag when two units make more sense.
Complete the system
What goes with a screw compressor
The compressor is stage one. Treat and store the air downstream.
Refrigerated dryer
Dry the air to near +3 °C before it reaches your plant.
Air filters
Remove dust, oil aerosol and moisture to your chosen class.
Automatic drain valves
Drain condensate without losing compressed air.
Air receiver
Sized by us. Steadies pressure and cuts compressor cycling.
After the sale
Installed, commissioned and serviced by VIMCO
