Screw compressors CIAT direct expansion shell and tubes evaporator equipment (High Power System) Cooling or heating Heat recovery ENVIRONMENTALLY HFC R134a PROTECTION DE FRIENDLY L'ENVIRONNEMENT Cooling capacity : 420 to 1030 kw Heating capacity : 520 to 1270 kw USE HYDROCIAT LW The HYDROCIAT LW water chillers with water cooled condensors and screw compressors are designed for indoor installation and offer an optimal solution for any refrigeration application in the air conditioning or industrial process. The use of HFC R134a refrigerant fluid means that the units respond to the most stringent specifications for environmental protection, high efficiency and low electrical consumption The units conform to regulations EN 60.204 EN 378-2 and to directives : - Machine (98 / 37 CEE) modified - CEM (89 / 336 CEE) modified 92/31 CEE - 93/68 CEE - Low voltage (73/23 CEE) modified 92/31 CEE - 93/68 CEE - DESP 97 / 23 CEE LW - LWP group 3 sizes 1800BX () to 2800BX () group 4 sizes 3200BX () to 4200BX () RANGE HYDROCIAT LW-LWP 2 compressors - 2 refrigerant circuits 8 models : LW - LWP -1800BX - 1800BX - 2150BX - 2150BX - 2500BX - 2500BX - 2800BX - 2800BX. 3 compressors - 3 refrigerant circuits 8 models : LW - LWP 3200BX - 3200BX - 3400BX - 3400BX - 3750BBX - 3750BX - 4200BX - 4200BX. HYDROCIAT LWP The design of the water/water heat pumps range HYDROCIAT LWP is identical to that of HYDROCIAT LW. These machines produce hot water for heating applications. They can also be used in the cooling operation by reversing cycle on the hydraulic circuits. 1
DESCRIPTION HYDROCIAT LW - LW P Compressors Accessible hermetic twin screw type Optimized profile of rotors ensuring a high efficiency Electrical motor incorporated with part winding start Integral electronic protection fo motor Control of the phases balance and rotation direction Integrated overpressure valve Discharge temperature control Lubrication under controlled pressure 3-stage integrated oil separator Crankcase heater Thin filter at suction Discharge valve Slide for modulating continued output capacity control Assembly on antivibration mounts Integrated oil separator Installed at the compressor discharge The large amount of oil injected during the compression cycle necessitates the use of an oil separator. Oil, after separation from the refrigerant, is filtered before being injected into the compressor. Note : The refrigerant oil has several important roles to ensure the smooth running of the compressor. It : Lubricates bearings and moving parts and eradicates any direct contact between parts. Ensures a secure tightness between the different mechanical parts, thereby guaranteeing good volumetric output. Cools the compressor by direct oil injection into the gas volume being compressed. If required, the cooling of oil allows gas discharge temperature to be limited. Evaporator High performance copper tubes bundle Steel tubular plates Steel shell Corrosion resistant baffles Thermal insulation with polyurethane foam Water cooled condenser High performance copper tubes bundle Carbon steel shell Carbon steel tubular plates Removable cast iron headers Safety valves on the refrigerant circuits (High Power System) on models LW/LWP... The system allows a significant increase in the cooling capacity, improving the performance coefficients (EER) of your installation, particulary in part load, and therefore ensuring an optimal operation of the unit all year round.

HYDROCIAT LWP The HYDROCIAT LWP water-water heat pump range has the same design as the HYDROCIAT LW. The calories are taken from the natural water network (ground water,...) or from a water loop and are sent to the heating network through the thermodynamic circuit, instead of being discharged by a cooling tower or a drycooler as is the case with the water chiller. These water-water heat pumps can be used for cooling by reversing the cycle on the water circuits (modification of the hydraulic circuits to be made on site).

DESUPERHEATER EXCHANGER LW - LWP The system consists in a hot water supplying by an heat recovery system on the compressors discharge gas, on an auxiliary desuperheater exchanger mounted in the unit. This optional equipment is only available on request, and factory mounted. Diagram of the refrigerant circuit The following refrigeration diagram describes an example of a CIAT unit, with desuperheater (on each refrigerant circuit). The heat recovery is possible only if the machine is running. For the same cooling or heating capacity, the desuperheater system allows a free heating of hot water with a reduction of the total input power of the machine. External sensor EVAPORATOR WATER Standard fitting Circuit 2 and 3 same conception than circuit 1 - - - equipment Only without equipment WATER DESUPERHEATERS OPTION WATER OPTION 1 : 3 ways valve fitting OPTION 2 : Compressor valve OPTION 3 : 3 ways valve fitting CONDENSER WATER Principle and precautions of hydraulic connection To start and to run the machine under good conditions, the water loop must be as short as possible, and the water flow of the desuperheater must start slowly with a water flow equal to 10% of its nominal value, and must be calculated for a hot water inlet temperature of +50 C. Thus, it is recommended to have a hydraulic diagram making it possible to obtain hot water very quickly at the inlet of the desuperheater (3-way valve + controller + temperature sensor on the exchanger water inlet) The controller set point must be adjusted to +50 C minimum. ds m s e Min. 50 C Optional desuperheater a 50 C v3v Domestic hot water circuit Note: particular attention must be given when selecting the expansion tank because the recovery water circuit can reach a Recovery example on desuperheater HYDROCIAT Cooling capacity Compressor absorbed Recovery Water flow Pressure drop LW - LWP Pf (kw) Pa (kw) Pr (kw) qv (m 3 /h) dp (mce) 1800BX 418 93 21 3.6 30 1800BX 433 96 22 3.8 33 2150BX 492 110 25 4.3 40 2150BX 533 115 27 4.6 45 2500BX 588 126 29 5.0 50 2500BX 625 134 31 5.3 60 2800BX 661 140 33 5.7 65 2800BX 692 145 35 6.0 70 3200BX 730 164 37 6.3 40 3200BX 762 167 38 6.5 43 3400BX 780 175 39 6.7 46 3400BX 808 180 40 7.0 49 3750BX 850 193 43 7.3 50 3750BX 883 198 44 7.6 55 4200BX 997 209 49 8.4 70 4200BX 1026 216 51 8.8 77 Note : heat recovery performances for : machine running in full load, chilled water = +12/+7 C and condenser hot water = 30 C / 35 C C hot water temperature on recovery = +55/+60 C 11

The auto adaptive control of the units and modulating capacity control on each compressor means that the use of the anti-short cycle function and the installation of buffer tank is not necessary.

RECOMMENDATIONS FOR ASSEMBLY HYDROCIAT LW - LWP Installation HYDROCIAT LW - LWP are designed for indoor installation and must be protected from adverse weather and frost. A free space of 1 meter must be left all around the unit for access to the electrical panel and other components. A free space on one side is also necessary (equal to the length of the unit) in case one of heat exchangers needs to be removed. Sound level problems should be studied in detail. Before installing the unit, study and if necessary treat (with the assistance of a sound technicien) the various possible noise transmissions in relation to the premises and its structure. If necessary the machine should be equipped with anti-vibration mounts and flexible connections (recommended and proposed as an option). Hydraulic connections Water connections must be made in accordance with good engineering practice. Provide the accessories necessary for hydraulic circuits : - Expansion vessel, - Drain cocks at low points, - Isolating valves, - Air vents at high points, etc..., - Check that the water content in the installation is sufficient, - Provide, if required, a buffer tank. Commissioning In accordance with our installation and maintenance brochure. Electrical connections All the indications necessary for the electrical connections are mentioned on the electrical diagram enclosed with the unit (to be respected). These connections will be made in accordance with accepted engineering practice and conform to the regulations in force. Leave the control circuit switched on to allow operation of the crankcase heater. The electrical mains supply must be fitted with fuse or circuit breaker protection (to be supplied by the fitter). Maintenance See our operating and maintenance guide. Subscribe a maintenance contract. 23
