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 glass-
fibre-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.

EASY FLOWS
Instrotech is offering Kobold’s VKP
plastic flowmeters that operate on
a special suspended float principle
with cylindrical measuring tube and
spring-loaded float with orifice.
The float in model VKP-3 has
slots mounted onto the outside,
which protect the instrument from
soiling by capturing dirt particles.
The danger of the float jamming
is thus considerably reduced and
soiled liquids with a particle size
up to 400m can be measured
without difficulty. In model VKP-2,
TLT-Turbo has launched a new range of mechanical vapor recompression
(MVR) fans, with ceramic hybrid bearings that provide a long operational
lifespan. The fan offers numerous advantages with regard to performance
efficiency, minimal maintenance and high reliability.
The MVR fans have a lower maintenance requirement, high motor speeds,
a wide range of optimised impellers and the allowance for high temperature
and pressure increases.
The introduction of hybrid ceramic bearings underscores their commitment
to developing products in close alignment to their clients and their needs.
The hybrid ceramic bearings are lifetime greased and can be operated
the sharp-edged orifice in the
float renders the instrument less
sensitive to changes in viscosity.
The model VKP finds
application in lubricant circuits,
domestic electrical, installations,
machine tools, solar energy systems, cooling circuits, welding
machines, and pumps.

for up to 10 years without requiring maintenance. Factors such as allow for
operation of the fan below critical speed.
The TLT-Turbo MVR fan is suited to numerous applications in the chemical,
pharmaceutical, wastewater treatment, and the organic natural product
production industries as well as in the food and beverage process and
manufacturing sectors.
