Flexible: All models are capable of operating under standard water-cooled and
low lift chiller operation while the TTS300, TTS350 amd TTS450 have the ability
to operate at high lift for air-cooled or heat recovery operation. In addition,
the TTS300 has the ability to operate in medium evaporator temperature
applications with a range of 0 and -10 °C (between 32 and 14 °F).
Quiet: The low sound levels of the TTS compressor reduces customer
complaints in noise-sensitive applications and reduces the cost of
expensive sound treatment typically required of noisy screw
compressors. The TTS Series compressors have sound pressure levels as low
as 70.0 dBA at 1.5m (5ft), resulting in up to 8 dBA lower than a typical screw
compressor.
Low Global Warming Potential (GWP) refrigerant: All TTS compressor models are compatible with the non-flammable R-513A refrigerant
with low GWP as standard. They are also available with HFC-134a with no Ozone Depletion Potential.
Flexible: All models are capable of operating under standard water-cooled and
low lift chiller operation while the TGS230, TGS310 and TGS380 have the ability
to operate at high lift for air-cooled or heat recovery operation. In addition, the
TGS230 has the ability to operate in medium evaporator refrigerant temperature
applications with a range of 0 and -10 °C or 32 and 14 °F.
Quiet: The low sound levels of the TGS compressor reduces customer
complaints in noise sensitive applications and reduces the cost of
expensive sound treatment typically required of noisy screw compressors. The TGS
Series compressors have sound pressure levels as low as 70.0 dBA at 1.5m (5ft),
resulting in up to 8 dBA lower than a typical screw
compressor.
Environmentally Friendly: As part of the Danfoss Turbocor® long term refrigerant strategy, the TGS compressor portfolio uses the next-
generation refrigerant HFO-1234ze which features a Global Warming Potential GWP < 1 and zero Ozone Depletion Level (ODP). In addition,
all TGS models can be used with low GWP R515B which has an ASHRAE A1 safety classification.
Model TGS490
Environmentally Friendly: The new TGS490 is the world’s first oil-free, magnetic
bearing centrifugal compressor that offers the flexibility to be used with either
ultra low GWP HFO-1234ze or R-515B. R-515B has a GWP of 299 and an ASHRAE
A1 safety classification - allowing users to be compliant with applicable refrigerant
regulations and safety codes.
Lifecycle Cost Advantage: The new TGS490 features oil-free, magnetic bearing
technology for industry-leading performance with up to 40% better part load
efficiency versus fixed speed screw compressors and no mechanical wear or
performance degradation over the life of the compressor. With a large capacity
range up to 140 tons / 490 kW, the TGS490 can meet a 400 ton air-cooled chiller
capacity requirement with only a three compressor configuration.

Efficient: Two models are available: TTH375 with a nominal capacity of 107 tons
/ 376 kW and TGH285 with a nominal capacity of 82 tons / 288 kW. The TTH and
TGH compressor portfolio offers industry-leading efficiency with integrated part
load values (IPLV) up to 40% better than a comparably sized screw chiller.
Quiet: The low sound levels of the TTH and TGH compressor reduces
customer complaints in noise sensitive applications and reduces the cost of
expensive sound treatment typically required of noisy screw
compressors. The TTH / TGH compressor has sound pressure levels as low as 70.0
dBA at 1.5m (5ft), resulting in up to 8 dBA lower than a typical screw compressor.
