Water to water liquid chillers
30WG
20 -100 kW
A new Carrier unit –
designed for cooling
The latest addition to the Aquasnap range
The new generation of water-cooled chillers has been designed for industrial
and commercial cooling applications. With an ESEER rating above 5, the 30WG
operating costs are among the best on the market with short payback time.
The many options of the 30WG include variable water flow pumps, reinforced
sound insulation, stackability, master/slave control of two units and water
production down to -12°C. This makes it a unique combination of superior
performance and energy-efficiency.

n Its compatibility with the Aquasmart Touch Pilot System helps
reduce energy consumption
n The range is Eurovent-certified
n The amount of copper and steel used for the manufacture of 30WG was
reduced by 44 and 41%. The amount of refrigerant was also reduced
by 10% over the previous range.

Energy-efficient, compact, competiti
Superior features
Simple to install and easy
to maintain
n 100% compatible
The 30WG can connect to any source; weld
or drycooler.
n Flexible water connections
Designed for quick installation, the unit offers easy
water connections either from the top or rear.
n Stackable to save space
If water connections are at the back, two units
can be stacked to save space and allow staged
operation master/slave option.
4
n Compact performance design
The small unit size results in a minimal footprint.
The 30WG easily fits through a door or in a lift.
Enjoy peace
and quiet!
n Easy maintenance
All components are easily accessible, and there
is only one screw type and size for the entire
chassis.
The sound level is one of
the lowest on the market from 67 to
73.4 dB(A) in full load on which a low
sound option of -3dBA can be deducted.

n Drycoolers for increased energy efficiency
Carrier offers a wide range of drycoolers compatible
with this new range, available with extended control
features.
n Maximum safety and reliability
Condensing pressure valve control allows unit
operation with drycoolers in cold outdoor weather.
n Domestic hot water 60°C
This unit can heat domestic water up to 60°C on the
source side when cooling on the terminal unit side.
n Reversible in the water side 30WG can be controlled on evaporator or condenser side to provide
heating or cooling as standard.
Reduce your energy bill
n Variable water flow pump to reduce your operating costs
The optional hydronic kit is available with a self-adjusting circulating pump to
ensure optimised unit operation and reduced running costs. This option is available in both evaporator and condenser sides. Variable water flow pump can be
controlled on ∆t of constant pressure.
n Optimise comfort and savings with Aquasmart
The 30WG can be integrated into the Aquasmart Touch Pilot system, offering time
scheduling and zone management to ensure increased comfort and minimised
energy consumption.

the 30WG to your needs
Hydronic kit and water connections
Stackable unit
n Units can be supplied with a hydronic kit either on the
condenser or evaporator side.
n The hydronic kit includes a circulating pump, valves and
an expansion vessel.
n The circulating pump can either be fixed speed or with
variable water flow.
n Three control modes for reduced energy consumption:
- Unit monitoring for maximised performance
- Constant ∆t (°K)
- Constant pressure
n The stackable option allows a significant system footprint reduction and easier installation
in a small plant room. This option is available
for units with the water connections at the rear.
Aquasmart Touch Pilot System Manager
optimises up to 128 zones
n Zoning and time scheduling manage the heating space and times, ensuring
enhanced comfort.
n Free-cooling system reduces for energy consumption by up to 2 kWh/m2 a year.
n Variable-speed pumps with reduced water flow at part-load conditions for
significant savings.
n A new generation of heat pumps guaranted for superior energy efficiency.
