BRUSHLESS EC MOTOR DOUBLES THE LIFESPAN OF BOSCH COMPACT TOOL
The addition of a brushless ec motor to the Bosch
GSB 18 V-EC Professional has doubled the lifespan
of the popular compact tool. “It forms part of the
Bosch ‘dynamicseries’, a series of compact tools with long
battery runtime based on tried-and-tested models,” says
Campbell Mhodi, Bosch Professional Power Tools Senior
Brand Manager.
Owing to the ec technology, they have a lifespan of
almost twice that of competitor tools. This makes the
tools especially suitable for serial applications, allowing
for quick and efficient operations in finishing trades such
as electricians, plumbers and joiners.
Bosch’s brushless ec motors are maintenance-free,
unlike conventional dc motors with carbon brushes. In
addition, they operate at an efficiency rate of 80%, as
opposed to the 60% to 70% efficiency rate of dc motors.
“This high efficiency means the tools do not get as
hot, and can perform up to 30% more work per battery
charge,” says Mhodi. In addition, Electronic Motor
Protection (EMP) protects the tools against overload by
shutting the motor down immediately if it stalls. The ec
technology also allows for a compact and lightweight
design.
Optional accessories for the GSB 18 V-EC include
CYL-9 multi-purpose drill bits for a range of diverse
construction activities.

The Energy Training Foundation (EnTF) is to
launch a Certified Water Efficiency Profes-
sional (CWEP®), Association of Energy En-
gineers’ (AEE) qualification programme.
AEE programmes recognise current knowledge
and work experience as requirements for obtaining
and maintaining their Certification programmes.
The CWEP two-day training session is a
culmination of work experience gained over years,
with a four-hour examination on day three (to be
passed with a minimum of 70%) in order to attain
the last eligibility requirement for the qualification.
Implementing water-efficient technologies or
techniques generally involves individuals with
varied backgrounds, responsibilities, and levels
of expertise. CWEP is designed to help educate
those who have responsibilities in the sustainable
or utility efficiency field on best practices for
maximising results and understanding water
efficiency basics.
The training will teach technical and
organisational strategies, including how to
conduct a water efficiency site assessment,
understanding water billing/costs, use of
terminology, regulatory and international
mandates and policies, efficiency technologies
and application techniques, as well as water
measurement and verification needs. Key
areas and sectors covered include commercial
kitchens, laundries, cooling and heating systems,
domestic plumbing systems, filtration, softening,
landscaping and irrigation systems, industrial
processing systems, pools, hospitals, medical
and laboratories, storm water management,
HVAC and mechanical equipment.
The training is ideal for Certified energy
managers; Energy and water administrators and
utility professionals; Water, energy and facilities
champions and Certified energy auditors;
Sustainability and energy professionals and
Government resource efficiency energy and
water administration managers, amongst others.
CWEP will take place in Johannesburg from 12
to 14 July this year with a second course from 16-
18 November, straight after the SAEE Convention
2017. In Kenya, additional modules will be added
to CWEP and the course will run from 12-15
September, with the exam on 18 September 2017.
