WELL COUPLED
Available in a variety of configurations, SKF’s range of
Disc Couplings provide affordable, lubrication-free service
in medium to high torque applications that require
torsional rigidity.
These innovative Couplings feature two hubs and a
laminated stainless-steel disc pack secured by a series of fitted
bolts retained by nylon insert lock nuts. With a capacity range
up to 178kNm in a variety of configurations including single
disc, double disc and spacer for both horizontal and vertical
mounting, these Couplings deliver several benefits to a vast
selection of applications.
SKF Disc Couplings encompass hub pilot bores to simplify
boring to requirements. This brings cost effective high
performance to a range of applications and industries
that use direct drive fan drives, pumps and compressors,
refrigeration (compressors) and marine.

UP THE ANTE
Carel’s range of pCO programmable controllers for the
management of HVAC/R applications and systems has been
extended with the addition of High-Speed controllers providing
a faster response to the efficiency of HVAC/R systems which
translates into faster unit set-up.
The calculation speed of the pCO5+ HS means it can respond
more quickly and precisely to variations in the main unit input
values (temperature, pressure, humidity, etc.).
pCO5+ HS guarantees compatibility with the entire range
of pCO3 and pCO5 controllers, in terms of both hardware and
software. Furthermore, Carel can be used to load the binary files
onto the new pCO5+ HS.
The pCO5+ HS makes the controller ideal for:
• Chillers
• Process chillers
• Data centres

COOLING EVEN FURTHER
In order to satisfy the increasing market requirements of electrical energy
requirements in data centres, ebm-papst has developed the tried-and-tested series of
RadiCal centrifugal fans further.
By employing computer-aided optimisation methods, the new RadiCal achieves
efficiency of 68.5% at an air flow of 13 000 m³/h. The new impeller is made of glassfibre-reinforced
polypropylene, the outer diameter and installation height have
remained the same - ensuring that the tight installation space in the air conditioners is
utilised to best effect.
ebm-papst products with GreenIntelligence have IoT capability and can be
interconnected with any system. The power electronics integrated into the EC motors meet requirements of a 0–10V control
signal or via Modbus RTU. Fans are available for all common line voltages and frequencies in sizes 310 and 630.
