INCORPORATING COLD CHAIN
‘Optyma-l’ temperature control
Danfoss has released inverter variable
speed technology versions of its Optyma
Plus packaged condensing units.
The Optyma Plus Inverter with variable
speed scroll compressor and drive deliver
the best Seasonal Energy Performance
Ratio (SEPR) on the market for refrigeration
applications in medium temperatures for
cooling capacities ranging from 2 to 9kW.
Offering a wide stepless capacity
modulation ranging from 30 to 100Hz,
Optyma Plus Inverter enables tight
temperature control to within ±0.3°C.
Danfoss inverter scroll technology allows
from 20 to 30% higher energy efficiency
for medium temperature refrigeration
applications compared to fixed-speed or
mechanically modulated condensing units.
The permanent magnet motor,
inverter-driven modulation, intermediate
compressor discharge valves,
together with the micro-channel
condenser contribute to a SEPR of
3.84, a performance level certified by
ASERCOM for R407F. Optyma Plus has
been developed to operate with R404A
alternatives R407A and R407F.

Fans for life
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 regarding
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 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 applications in
the food and beverage process and manufacturing
sectors.
