LTLS Series Screw Industrial Water Chiller for Air Conditioning

and Industrial Cooling, Screw Industrial Water Chiller

Features of Screw Industrial Water Chiller

1.30 sizes available ranging from 100 kW to 2000 kW cooling capacity, with heat recovery and low temperature output;

2.Wide application as hotel, apartment, villa, factory, shopping center, office building,school, etc.

3.Semi-hermetic screw compressor for all models. Each compressor is equipped with a crankcase heater and a thermal overload cut-out, the screw compressor is

also complete with a built-in electronic protection with temperature sensor located directly in the motor winding and on discharge line.

4.The refrigerant circuit is complete with sight glass, filter drier,high and low pressure gauges, solenoid valve, direct expansion valve, high and low pressure switch.

5.Shell and tube dry expansion type condenser, factory insulated with flexible close cell material.

6.The electric panel consists of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker,microprocessor control with function display.

7.LCD display, touch screen control panel as standard.
8.Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system.

9.For the units with semi-hermetic screw compressor, an infinitely variable capacity control system that is capable of exactly matching the demand requirement of the system is to be supplied. This system is to provide precise and stable control of supply water temperamture over the complete range of operating conditions.

OPTIONAL

Electronic expansion valve

Desuperheater as optional.

Electronic controller with BMS system.

Low noise compressor cabinet or outside full cover

 Screw Industrial Water Chiller System Control
1.Imaged system operation chart, showing the temperature of water in/out, the

energy level of compressor run, on/off button,run time, alarm etc.And the remote

turn on/off function is available. PC remote control is optional.

2.Notice for maintenance is indicated according to the accumulated run time of

the compressor.It is convenience to maintenance.
3.The control system will automatically balance the run time for each compressor for

mult-compressor unit.

Screw Industrial Water Chiller Safety Protections
1.Discharge check value:it prevents the discharged gas from going back after the compressor stops.

2.Phase lack protection:It protects the compressor for over high voltage, voltage dificiency, and phase lack.

3.Direction protection:It protects the compressor from damage resulted from Counter direction run.

4.Oil heater: It heats the oil before the unit start, keep the good lubrication for the unit before it runs.

5.Overheat protection inside the motor of the compressor: It protects the compressor from burning down for too high coil temperature for overload, or abnormal run condition.

6.High&low pressure protection:It protects the compressor and system against extreme run condition and trouble.

7.Freezing protection:It protects the unit form too low temperature of the water out,freezing may occerat some place,resulting in freezing breaking of the evaporator.

8.Water flow protect:It protects the unit from run without water flow.
9.High temperature of chilled water protection: It works to protect the compressor in case that the load is too large,the temperature of chilled water is too high.It may result in compressor failure without this protect in the case.The technical data in this documents

are not binding. LVTE AIR CONDITIONING SYSTEM CO.,LTD.
