ENCLOSURE — SCR compressors are designed to be maintenance friendly, all
components are easily accessible via large rugged, removable and locking
panels. Components are mounted on a substantial base that can be moved by
a fork lift truck. This enclosure is also designed to reduce noise levels.
TRANSMISSION — The SCR D range compressor uses a 1:1 direct drive for
greater durability & efficiency.
A German KTR coupling is used throughout the range.
This means reduced transmission losses and great reliability.
It also provides a more compact package that is simpler to maintain.
Energy savings of ~5% are achieved with direct drive technology.
COOLING — SCR oversize the air and oil coolers by 30% compared to
competitors compressors.
This gives greater reliability and efficiency in arduous environments.
PIPE WORK — SCR use seamless steel pipes with high quality compression
fittings, rubber hoses are not used! This eliminates oil leaks from ageing and
vibration.
OIL SYSTEM — 15% larger pipe work results in a 30% reduction in pressure
drop through the oil circuits. Synthetic oil can also be specified for further
cost savings.
AIRENDS — Ally-Win is a joint venture established in Germany producing one
of the highest quality airends available. They are fitted with patented German
rotors, SKF bearings and EU made Teflon oil seals. Triple lip seals combined
with double inner seals protect the rotors.
Oversized airends are specified for greater durability and efficiency.
Many competitors use high speed air ends to reduce manufacturing cost at
the detriment of energy and reliability. These high quality components
ensure high efficiency, durability and low noise levels.
Efficiency improvements of 5-10% are delivered.
WWW.SCRAIR.CO.UK
AIR INTAKE — The intake air control valve is a low pressure drop design
giving optimum performance and reliability. It is electronic rather than
pneumatic, resulting in less wearing parts and no issues with air leaks.
These have been tested to over 2 million cycles.
CONTROL & ELECTRICS — The patented and user friendly European
controller has 12 alarms and comprehensive safety trips/protection. It’s
easily configured for energy efficient operation. Siemens control gear is
used throughout to ensure long term reliability. Solenoids and sensors from
ODE & Huba are also used for improved accuracy.
MOTORS — Premium efficiency motors to the latest MEPS directive are
used for reduced energy consumption.
