“ENERGY SAVER” HEAT PUMP UNITS
SERIES: ERACS-R
These units are used two-pipe systems and provide hot
and cold water, depending on the season,
as well as domestic hot water all year round.
The main applications are hotels, sports centres and gyms.

-10°C OUTDOOR TEMPERATURES
As operation in the heat pump mode is guaranteed
at outdoor temperatures as low as –10°C,
the ERACS-Q ERACS-R range is a valid alternative
to traditional systems.

INNOVATIVE DEFROSTING SYSTEM
(CLIMAVENETA PATENT)
The ERACS-Q ERACS-R units incorporate an innovative cycle reversal
defrosting system whose algorithms can be customised according to
individual requirements.
55°C IN THE HEATING SYSTEM
The ERACS range offers users heating
water temperatures of up to 55°C even at low
external air temperatures.
This is a valid solution for heating
and domestic hot water production systems.
11 SIZES IN 4 VERSIONS
195 kW TO 660 kW
The large number of sizes ensures the range fully
satisfies all system requirements.
All sizes are present in each of the 4 versions:
B: Standard unit
LT: Low outdoor air temperature unit
LN: Low noise unit
SL: Super low noise unit.

COMPRESSORS
An improved generation of screw compressors featuring an extremely compact structure
and optimised for R134a has allowed the volumetric displacement to be substantially increased
without modifying the shape of the compressor.
Elevated cooling capacities can thus be achieved with improved volumetric efficiency.
• Screw profile: dual rotor design
Compared with a traditional screw compressor,
the profile has been modified so that the
increased volumetric flow rate requires just
a 10% increase in size, a fundamental aspect
of rotors. It was therefore possible to modify
the body without affecting the external shape
of the compressor.
• Roller bearings
Thanks to the favourable torque load
and the reduced pressure difference,
the bearings work in easier conditions
and therefore last longer.
SCREW PROFILE
OIL
SEPARATOR
• Oil separator
The compressors contain
an integrated three-stage oil
separator which can guarantee
extremely high separation levels,
in spite of the increase
in volumetric flow.
This is achieved thanks to the fact that
the limited density of the vapour and
the outlet temperature of the R134a
allow outstanding oil separation.

NEW CONTROL UNIT
The main characteristics of the new control unit concern the user interface, unit management,
compatibility and Service functions.
User interface
Positioned in an easily accessible area
on the outside of the unit and protected
by a transparent cover.
It integrates a graphics display with
a multilanguage menu for reading and setting
parameters, a synoptic panel which,
by now a traditional feature of Climaveneta,
offers an immediate view of compressor
status.

Unit management
Special control algorithms optimise energy saving and guarantee maximum system reliability:
compressor starting/stopping management with hourly rotation + FIFO, thermoregulator
management of available resources, variation and control of operating parameters, monitoring
of critical temperatures and phase sequences. The software, especially developed by
Climaveneta, offers modulating control of unit capacity from 100% to a minimum which,
depending on its size, can be as little as 12.5%.
Compatibility
Compatible with the supervision systems of Climaveneta, De’Longhi and many other BMS
systems present on the market: METASYS ® , MODBUS ® , LONWORKS ® , SIEMENS ® , TREND ® .
FWS supervision
The controller is also compatible with the innovative Climaveneta FWS (Field Web Server)
supervision system.
Service
The new “black box” logs data relative to 200 variables,
acquired every 30 seconds during the 10 minutes
preceding an event, for 400 separate events.
The software is compatible with the Climaveneta Service
programme: through a remote Internet link it is possible
to monitor the unit, implement preventive and corrective
action and consequently offer a more effective and higher
quality of service.
TOTAL HEAT RECOVERY
The ERACS-R units recover the entire heat capacity of the compressor for the production of domestic hot
water. This can be achieved both in summer and in winter by assigning operating priorities.
LOW-NOISE VERSIONS
Two noise reduction versions are available for all sizes:
low noise and super low noise.
Low noise levels are achieved by reducing fan speed
while the circuitry has been optimised and the coils
generously sized to ensure the unit works correctly.
The compressors and cooling circuit components
are enclosed in a large soundproofed box.
