GENERAL CHARACTERISTICS
Low GWP refrigerant Latest revision of F-GAS, entered into force in 2015, set up a phase down program for
traditional HFC’s refrigerants. In 2018 first significant reduction step will be introduced (37%) and in 2030 the
reduction (calculated in equivalent CO2 tons) will need to achieve almost 80%.
The most popular hydro-fluorocarbon (HFC) refrigerants for screw chiller applications is R-134a, that is the
first non-ozone-depleting fluorocarbon refrigerant to be commercialized. It is a single-component refrigerant
with no glide.
R1234ze Refrigerant R-1234ze is the best alternative with low GWP for screw chiller applications. It belongs to
the family of HFO fluids (Hydrofluoroolefins): like traditional hydrofluorocarbons (HFCs), they are composed
from hydrogen, fluorine and carbon. The only difference is that they are unsaturated and contain a carbon-
carbon double bond, featured by zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming
Potential<11), resulting in low TEWI (Total Equivalent Warming Impact).

R-1234ze is categorized under the A2L flammability class of ASHRAE. For installation requirements, please
refer to IOM manual.
Evaporator
Single circuit models (Plate Heat Exchanger) The unit is equipped with a direct expansion plate to plate
type evaporator. This heat exchanger is made of stainless steel brazed plates and is covered with a 20mm
closed cell insulation material. The exchanger is equipped with an electric heater for protection against freezing
down to –28°C and evaporator water connections are provided with victaulic kit (as standard). The evaporator
has 1 circuit (one compressor) and is manufactured in accordance to 2014/68/EU. Flow switch on evaporator
available as option (shipped loose). Water filter is a standard option for single circuit unit.
Note the installation of the filter is mandatory.
Dual circuit models (Shell&Tube) The unit is equipped with a direct expansion Shell&Tube evaporator with
refrigerant evaporating inside the tubes and water flowing outside. The tubes are enhanced for maximum heat
transfer and rolled into steel tube sheet and sealed.
The evaporators are single-pass on both the refrigerant and water sides for pure counter-flow heat exchange
and low refrigerant pressure drops. Both characteristics contribute to the heat exchanger effectiveness and total
unit’s outstanding efficiency. The water side is designed for 10 bar of maximum operating pressure and is
provided with vents and drain.
The external shell is covered with a 10mm closed cell insulation material and the evaporator water connections
are provided with victaulic kit (as standard). Each evaporator has 2 circuits, one for each compressor and is
manufactured in accordance to 2014/68/EU. Flow switch on evaporator available as option (shipped loose).
Water filter is not available as option from the factory.
Note the installation of the filter is mandatory.
Condenser The condenser is made entirely of aluminum with flat tubes containing small channels. Full-depth
louvered aluminum fins are inserted between the tubes maximizing the heat exchange. The Microchannel
