2 The power of The extensive range of Hydrociat chillers can meet a wide variety of liquid cooling requirements. Different versions find applications in offices, collective housing hotels, industrial processes, etc. The environment: a top priority CIAT is committed to protecting the environment. HYDROCIAT complies with applicable s for protecting the ozone layer (ODP - Ozone Depletion Potential) and limiting the greenhouse effect (GWP - Global Warming Potential). All HYDROCIAT components are optimised to operate with R407C or R134a refrigerant ensuring high performance coefficients, reduced energy consumption and extended service life. The refrigerant circuit was studied in detail. Each step is verified, ensuring that each unit is perfectly leak-tight. A direct expansion evaporator is used, with minimum refrigerant charges.

3 High-performance, communicating control system for greater adaptability CIAT's latest development in intelligent digital control systems, Xtra Connect uses specific parameters and an array of sensors to control the operation of any HYDROCIAT packaged water chiller with unrivalled precision. Components are controlled automatically for continuous operation and a specific algorithm is used to offset any drift in operation. The water temperature set is always maintained regardless of operating conditions. Adaptive control Adjusts to suit any system set-up (water inlet or outlet control, water formula according to climatic conditions and ice storage) and manages two remote switchable setpoints. User-friendly - ergonomical Multi-language - Fault memory Control - Monitoring - Parameters Remote communication All methods of BMS (Building Management Systems) possible via the RS 485 serial port and MODBUS/JBUS open communication protocol. Numerous safety devices Water flow control, antifreeze protection, phase inversion protection, discharge temperature control, high and low-pressure protection, and anti short cycle safeguard your packaged water chiller and extend its life. Output contacts Fault per circuit and pump control output contacts. Outputs: Faults Pump control BMS RS 485 Entrées Inputs: : MODBUS/J BUS Commande External externe control Commutation Set points switching consigne Set Ajustement points adjustment consigne Load Délestage shedding Input contacts Inputs for external control (clock, BMS, etc.), setpoint switching, remote setpoint adjustments (0-20 ma signal) and compressors load shedding on any HYDROCIAT unit. Easy to use ergonomic interface With an LCD screen that displays operating status, parameter readings, temperature, pressure, operating times and a log menu that records up to nine previous faults, the Xtra Connect interface makes running your system an easy task. Moreover, the display can be installed away from the chiller for more convenient monitoring

The fruit of our research and experience, the new exchangers optimise space, capacity and performance.

4 More powerful, Optimised exchangers Today, CIAT is a world reference in exchanger design and manufacture. For over 70 years we have been working on ways to provide maximum cooling capacity, reduce volume, and limit pressure drops. The fruit of our research and experience, the new exchangers optimise space, capacity and performance. Evaporators, with two or three refrigerant circuits and one hydraulic circuit, were specially developed by CIAT for the HYDROCIAT range. Making connection on site is very simple. The flow switch and all the sensors required for correct, safe operation are fitted, tested and adjusted in the factory. HYDROCIAT chillers are supplied with a transformer fitted on the control panel. A single mains supply with no neutral is all that is required. The units are compact and easy to install. Easy installation saves time on sites All units are tested in factory and follow ISO 9001 procedure. Powerful and compact up to 160 kw/m 2 Due to the heat exchangers design with high exchange coefficients, and compact accessible hermetic compressors with integrated oil separators, HYDROCIAT units are very compact, allowing an easy installation in all technical rooms. The HYDROCIAT range saves space by reducing the chiller's footprint in technical rooms, making space for other equipment (pumps) and easier maintenance access.

5 but as compact as ever The HPS* system An economical solution Proposed on all HYDROCIAT units, HPS technology allows to increase cooling and heating capacity and the performance coefficients (EER and COP), particularly through capacity control. HPS keeps the HYDROCIAT running at optimum condition all year long. * HPS = High Power System Compact and accessible hermetic screw compressors Best technology ensuring POWER, EFFICIENCY and SAFETY HYDROCIAT chillers use the latest generation of compact, accessible, hermetic screw compressors. The latest-generation accessible hermetic screw compressors are small, quiet and high-performance. The rotors, designed with a stable profile for higher performance, are precision machined to significantly increase their efficiency by reducing rubbing and by-pass. The screw compressor has fewer moving parts and is coupled directly to the gearless drive for lower vibration levels. The rubber anti-vibration mounts maintain noise at a low level The compressor used by HYDROCIAT allows a wide operating range with a particularly high performance. Despite their high capacity and with compressors part winding and cascade control starting, HYDROCIAT units keep an acceptable starting current. The small number of moving parts, high-quality components (such as aeronautical bearings), optimised oil management, and maximum and continuous motor cooling mean longer life for the HYDROCIAT units with no servicing or heavy maintenance required..
