Demand-responsive chillers with oil-free Turbocor compressors
Lightstream Turbo chillers were designed with attention to every detail to maximize efficiency and reliability and fit ideally to the requirements of mission-critical applications like data centers, telecom facilities and clean rooms, and in every area where reliability is a key factor.
Due to its excellent efficiency under part-load conditions, Lighstream Turbo chiller family is a brilliant economy solution for applications where the heat load is not constant or expected to increase.
Turbocor oil-free compressors
EXCELLENT ENERGY EFFICIENCY AND UP TO 25% SAVINGS IN OPERATING COSTS
Turbocor compressors offer the outstanding energy savings from digitally controlled, frictionless two-stage centrifugal compression and guarantees significant reductions in operating cost and environmental emissions associated with energy production.
The oil-free design of Turbocor compressors eliminates the potential for oil contamination having a negative impact on efficiency and all associated accessories: oil heaters, oil pumps, oil separators, oil filters, plus oil disposal.
Compressor soft-start draws only two amps and reduces mechanical stress, as well as the electrodynamic stresses on the power cables and electrical distribution network, extending the overall lifespan of the system.
HIGHER ENERGY SAVINGS
LOWER CONDENSING TEMPERATURES
ENHANCED HEAT TRANSFER
Microchannel condensers used in Lighstream Turbo design provide numerous benefits, including higher heat transfer rate, low airside pressure drops, and closer approach temperatures. The result is up to 40% higher energy efficiency in comparison to a traditional fin/tube heat exchanger design.
Smaller coil face, thin design, up to 50% less weight, and less refrigerant charge result in lower system costs. Microchannel condensers used in Lightstream Turbo chillers are HVAC coils developed and optimized especially for refrigeration applications and enable remarkable low condensing temperatures.
EXTRA CONDENSER SECTIONS FOR HIGHER EFFICIENCY
Lightstream Turbo H-series chillers feature extra condenser banks which enable lower condensing temperatures, 15% higher energy efficiency rates (EER) compared to standard Lightstream Turbo models and reduced noise emission level.
EC-TYPE FANS WITH REDUCED POWER CONSUMPTION
Lighstream Turbo’s new generation fan system not only reduces power consumption by up to 30% while easily managing the extraordinarily high volume flows – it also works at the lower operating noise.
The smart fan system includes unique fans with the bionic wing concept, the most advanced EC motor technology, and multifunctional air diffusers, resulting in increased economic efficiency for the customers.
EC motor technology not only produces savings in full-load operation - it is exactly when operating under partial load that EC motors lose much less of their efficiency.
LOW-GWP REFRIGERANT OPTION
Refrigerants with low global warming potential (GWP) are becoming more and more important in the refrigeration and air conditioning industry in Europe and beyond.
R1234ze features low GWP of one and zero ozone depletion potential, thus providing the environmental leadership while achieving the best energy performance levels for applications.
The flooded evaporator enables operation at higher saturated evaporating temperatures compared to many other types of evaporators and permits a higher cooling capacity with correspondingly higher efficiency.
The refrigerant pool acts as a flywheel, allowing the controls of the flooded evaporator to track the varying load of a batch process, while optimized tube geometry ensures optimal refrigerant distribution.
GENERATES ENERGY SAVINGS ALL YEAR ROUND
Lightstream Turbo chillers can supply chilled water with relatively high temperatures, thus maximizing the amount of time the system can produce chilled water without running the mechanical cooling mode. Compared to conventional chillers, Lightstream Turbo equipped with free cooling system generates energy savings of up to 50% and returns investments within a short timeframe.
When running in concurrent free cooling and mechanical cooling mode, the control system constantly monitors the condensing temperature and keeps it within the scope of the compressor to allow the maximum possible fan speed and achieve the maximum free cooling. During periods when the fan speed has to be reduced to a minimum, the chilled water temperature is controlled via motorized valves.
A vast range of Lightstream Turbo chiller models and options provides flexibility, tailor made to customer requirements permitting truly efficient cooling solutions for every application in any climate zone.
In a 24/7 world, ensuring facilities stay up and running is critical, therefore special attention has been paid to control and monitor functionality, and ensuring operational reliability and ease of maintenance.
