Benefits

Improved Carbon Footprint

In an oil-free compressor, there is no risk of oil contamination to products or equipment. Furthermore, installation, energy and maintenance costs for condensate treatment, filter system or compressed air treatment are avoided. The result is a greatly improved carbon footprint.

Significant Energy Savings up to 20%

CompAir's oil-free piston compressors deliver possible energy savings of up to 20% over comparable technologies. The significant energy savings result from the low input power at full load, the narrow pressure band and the low off-load losses.

Short Payback Times

High-quality, robust construction along with excellent efficiency means that payback times are short. With its long economic life cycle, the R-Series can supply affordable compressed air, year after year.

Comprehensive Electronic Control

The multilingual Delcos 3100-R control system ensures safe and reliable operation and continuously monitors the operating parameters to protect your investment.

Easy Installation

Being wired ready for connection, the units are easy to install and require no additional foundation.

High Air Quality

Generous dimension tubular coolers allow for water cooler technology to replace traditional oil lubrication. This ensures absolutely no risk of contamination and a Class 0 air output.

Maximum Availability and Efficiency

The design of the double-acting high-performance compressor offers a big reduction in electrical input power, at both full and half load. Rapid switching from full load to half load and back again ensures a flexible response to compressed air demand and a low-pressure difference in the network. At the same time, off-load losses are minimised, at just 8-9% of generating capacity in the case of piston compressors.

The significant energy savings result from the low input power at full load, the narrow pressure band and the low off-load losses.

Full load: 100% volume flow ➔ 100% power input
Half load: 50% volume flow ➔ 53% power input

Design

Piston Technology

A reciprocating compressor is a positive displacement compressor that uses a piston to compress air and deliver it at high pressure. The overall design of a piston compressor is similar to an internal combustion engine. A central crankshaft will drive the pistons, this is powered by a motor. As the piston is drawn backwards, gas enters the compressor through the intake valve. The gas is then injected into the cylinders of the pistons and the reciprocating action of the piston compresses the air.

R180

Being wired ready for connection the units are easy to install and require no additional foundation. The R series is water-cooled, with generously dimensioned tubular coolers. The piston and guide rings are made from high-quality materials, with a central guide ring and piston rings above and below for an effective, low-wear seal, eliminating reverse flow losses. The IP55 electric motor has a low rotational speed of 1000 rpm. There are no separate components.
