1. INTRODUCTION
2. OPERATION LIMITS
 Series CIATCooler LP
Air-condensed water chillers.
 Series CIATCooler ILP
Reversible heat pump units for operation in negative outdoor
temperatures (greater than -15ºC WB) for water heating and chilling.
Defrosting by reversing the cycle.
After manufacturing, all units are charged with refrigerant and
are tested at the factory, verifying the correct operation of all their
components within the operating range for which they are intended.
The units comply with European Directives: Machinery 2006/42/EC -
EMC 2014/30/EU - LVD 2014/35/EU - PED 2014/68/EC (Category 2)
- RoHS 2011/65/EU - Eco-design 2009/125/CE - Eco-labelling 2010/30/
EU; and with Harmonised Standard: EN 378-2:2012.
Those in charge of the installation, commissioning, operation and
maintenance of the unit must know the instructions contained in this
brochure and the specifi c technical characteristics of the installation
place.

Heating capacity:
17,7 to 193,5 kW
21,8 to 214,0 kW
The CIATCooler LP / ILP cooling units and reversible heating pumps
are compact outdoor air/water units.
Available in two versions:
• STD (Standard)
• HEE (High Energy Effi ciency)
These units have been made for operation indoors in the production
of hot and/or cold water, applicable to heating, cooling, and industry.
They are equipped with centrifugal fans (STD version) or electronic plug-
fans (HEE version), plate exchangers, hermetic scroll compressors, and
electronic control with microprocessors, components optimised for the
R-410A refrigerant.
This range is also offered with an integrated circulation pump: LPC /
ILPC and optionally, with a hydraulic module (attached to the unit or
separate) equipped with a buffer tank.
The entire range also has the option to include a desuperheater circuit
that allows for the production of hot water at a temperature greater than
in the condensation circuits.
 With control of the condensation pressure operating up to -15ºC.
 Minimum outlet temperature. With the option of glycol water for lower temperature
operation from 5ºC to -7ºC.
