    LXH - LXC series

    The “ALL INTEGRATED” solution

    The PLUG and COOL solution offered byPOWERCIAT LXH - LXCThe hydraulic equipment integrates all the components necessary for the correct operation of the installation :

    - 950 litres insulated buffer tank (LXH only)

    - 80 litres expansion vessel

    - Large choice of single or twin pumps for high head pressure (1)

    - Manometers with shut off valves

    - Pressure relief valves (calibrated at 4 bars)

    - Drain circuit

    - Manual and automatic air vent

    - Control of the assembly

    - Antifreeze protection (optional)

    The hydraulic equipment, whose components have beenselected in an optimal way, mounted and tested in factory,makes the installation of units easy and economical.

    The preparation/commissioning times and the space required on site are therefore perfectly optimised.

    (1) Our pumps are designed for operation on a closed water loop (lowNPSH). For other applications, consult us (open water circuit, importantintake height, etc).

    DESUPERHEATHER EXCHANGER LX - LXH - LXCThe system consists in free hot water supplying thnaks to heat recovery on the compressors discharge gas, through an auxiliarydesuperheater exchanger.This optional equipment is only available on request, and factory mounted.

    ■ Diagram of the refrigerant circuitThe 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 thetotal input power of the machine.

    ■ Recovery example on desuperheater

    Note : heat recovery performances for :➨ machine running at full load, chilled water = +12/+7°C and outside air = +35°C°C➨ hot water temperature on recovery = +55/+60°C

    ■ Principle and precautions of hydraulic connectionTo start and run the machine under good conditions, the circuitmust be as short as possible, and the water flow of thedesuperheater must start slowly to normal operating condition,with a water flow equal to 10% of its standard value, and mustbe calculated for a hot water inlet temperature of +50°C.Thus, it is recommended to have a hydraulic diagram making itpossible to obtain very quickly a hot water at the inlet of thedesuperheater (3-way valve + controller + temperature sensoron the exchanger water inlet)The controller set point must be adjusted to +50°C minimum.Note: pay attention to the selection of the expansion tank,because the recovery water circuit can reach the temperature of115°C in the event of circulator stop or non hot waterconsumption.

    MINIMUM CHILLED WATER PIPING VOLUMES

    POWERCIAT LX - LXH - LXCXtra Connect microprocessor fitted on POWERCIAT units allows a very flexible adjustement of the operation in comparison withthe drift of parameters, especially for hydraulic installation with low water volume.The auto adaptive control of the units and modulating capacity control on each compressor avoid the use of anti-short cyclefunction and the installation of buffer tank.

    Minimum chilled water piping volumes calculation for the following conditions :- chilled water temperature : 12°C / 7°C- condenser air inlet temperature : 35°C

    NOTE :Installations with important thermal variation or industrial process designed to supply very constant water temperature, must be equipped with buffer tank. (LXH alternative selection)
