23 Pressure Safety Valve (registered Patent)
Freeze and Burst will not be occurred by safety equipment during operation. This valves prevents deformation of the chiller by pressure when an inner heat tube is damaged by abnormal operation. Structure Cover
Pressure Relief Vent
Operational principle of a Vacuum Valve ☞ Release internal pressure when Disk & Cover ascend up to head of the volt as ascending pressures of main body.
24 Low load control system
Decrease of electricity consumption by stopping pump in low load operation
Low load control logic
Unnecessary electricity consumption would be decreased by stopping refrigerant pump, absorbent pump, cooling water pump and cooling tower fan when outlet temperature of chilled water is under the settled temperature and it doesn’t increase above settled temperature for a period of time .
