medium-capacity machines specifically designed for heating                        Cooling-only version without hydraulic system
and air-conditioning applications in office buildings, healthcare
facilities, industrial environments, businesses and homes.
                                                                                  AQUACIATpower LDC - LDH series
These packaged units are specifically designed for outdoor
installation and require no special protection from adverse                       Cooling-only version with hydraulic system (circulator pump

They use the outdoor air as the sole transfer medium, dumping
indoor heat into it during the summer and absorbing heat from                     AQUACIATpower ILD series
it during the winter.                                                             Air-to-water reversible heat pumps without hydraulic system
When connected to a radiant floor heating and cooling system,
fan coil units or an air handling unit, the ILD - ILDC - ILDH                     AQUACIATpower ILDC - ILDH series
series of reversible AQUACIATpower units makes heating                            Air-to-water reversible heat pumps with hydraulic system
and air conditioning buildings extremely easy.                                    (circulator pump only or pump and buffer tank).
Each unit is delivered fully assembled, wired (control and
power), charged with refrigerant and factory tested.
Simply make the necessary electrical and                          hydraulic
connections, and your unit is ready to operate.

SEASONAL              PERFORMANCE
Most central air-conditioning systems used in the service industry in Europe use water chillers to produce cold.
Until recently, the efficiency of air conditioners in Europe was measured using a single nominal test point under full load, called
Energy Efficiency Ratio (EER). However, a unit’s efficiency depends on its operating conditions.
Analyses of installed systems show that heat load varies from season to season and that a water chiller operates primarily at
reduced capacity.
The European Seasonal Energy Efficiency Ratio (ESEER) measures the seasonal efficiency of water chillers by taking into
account their efficiency under partial load using formulas created by the European certification body Eurovent.

The efficiency under partial load is therefore essential when choosing a water chiller.
It is with this in mind that the new AQUACIATpower range was designed. In particular, the entire range uses R410A refrigerant
which, thanks to its extremely high thermodynamic performance, makes it possible to obtain much higher EER and ESEER
ratings than with R407C and as much as 25% less electricity consumption.
As its compressors are connected in parallel on the refrigeration circuit, AQUACIATpower easily and efficiently adjusts the
cooling capacity to system’s needs. The self-adjusting CONNECT control anticipates variations in load and turns on only the
number of compressors needed. The compressors operate at optimum performance, energy efficiency is extremely high all year-
round and, as a result, the system remains energy efficient for most of its life.

LDC - LDH - ILDC - ILDH series                                                                       ■ LDH - ILDH series hydraulic module

The All-in-One solution

The Plug & Cool solution offered by
AQUACIATpower LDC - LDH - ILDC - ILDH
The hydraulic module contains all the water circuit
components needed for the system to operate correctly:
- 950 litre insulated buffer tank. (LDH - ILDH only)
- Expansion vessel:
    . 80 liters for LDH - ILDH
    . 50 liters for LDC - ILDC
- 600 micron water filter
- Wide selection of single and dual pumps for your system’s
flow and pressure requirements. (1)
- Pressure gauges with shut-off valves.
- 4 bar safety valve.
- Drain line.
- Manual and automatic air bleed valve.
- System control.
- Frost protection (option).
The components in the hydraulic system are carefully
selected and factory assembled and tested to make the
installation of the units simple and economical.
Preparation times, implementation times                                   and     space
requirements are thus kept to a minimum.

(1) Our pumps are designed to operate on closed water loops (low
NPSH). Please consult us for other applications (open water loop, high
NPSH).

This system, present as a standard feature on CIAT’s CONNECT

of an air/water heat pump.                                                                                             110 %

The result is an increased reliability of the heat pumps as well as an
excellent optimization of the cycles frequency by privileging the cold

LD - ILD (H - C)              SERIES DESUPERHEATER (HEAT EXCHANGER)
Heat from gases released by the compressors can be recovered directly by a type of heat exchanger - called a desuperheater -
on an AQUACIATpower unit to produce free, additional hot water.
On reversible units, the desuperheater option can be used in both heating and cooling modes.
This optional configuration requires assembly in our factories.

LD (H - C)              SERIES         - TOTAL          RECOVERY WITH A HEAT EXCHANGER
Free, additional hot water is produced at medium temperature by adding an air-cooled condenser to each circuit. The air-cooled
condenser is placed upline of the air-cooled condenser on each circuit to recover all the heat released by the unit.
This option is available on cooling-only version units only.

SOUND            LEVELS
The distinguishing feature of the AQUACIATpower range is its rigorous design incorporating “noiseless” assembly techniques
which reduce vibration and noise.
■ Compressors on anti-vibration mounts
■ Pipes dissociated from body of unit
■ Low-speed fans
■ Automatic air-flow adjustment
■ Units on anti-vibration mounts (option)

The Connect controller uses anticipation logic making it particularly flexible in adjusting operation to changes in settings,
particularly on low-volume hydraulic systems.
By adjusting compressor running times, it prevents short-cycle protection cycles from starting and, in most cases, eliminates the
need for a buffer tank.

Comment: A buffer tank may be installed on systems used in industrial processes that may require highly stable water
temperatures or on systems with highly fluctuating heat loads.
In the case of heat pumps, the drop in water temperature caused by defrosting must be factored into the volume of the hot water
tank.
