Emerson CSU 3000 User Manual 2
Specifications and Main Features
- There are other models listed in the Model Number Designation Tables which have the tonnage capacity ranging from 5, 10, or 37 tons (for example, DS065A-A and DS 065 - A of 5 Ton capacity).
- There are 3 general classes of units which include Air Cooled, Water Cooled, and Glycol Cooled
- Option for capacity include: 5, 7.5, 10, 12, 15, 20, 30, and 37 tonages.
- Comes with Sentinel 3000/Alarm Monitor for supervising the functioning of the system and also triggering of alarm in case of system malfunction.
- Comes with PCR 3000/Status Panel with push start and stop switches for controlling the working of different modules which are associated with the panel such as operational lights.
- For the purpose of compressor protection works high and low refrigerant pressure switches.
- For regulating the flow of refrigerant which is to be transferred to evaporator thermostatic expansion valve is employed.
- For the reason of low loads, hot gas bypass valve is used to control evaporator temperature.
- For exceptional instances where water flow is stopped a flow switch is used to cut off the chiller module.
- For the instances where the evaporator temperature ranges to 34°F (1°C) free state is used to prevent further refrigeration.
- Alternate Water Source(AWS) and Glycool/Free Cool Modules are the additional modules that can be ordered separately.
- For efficiency and lifespan, preventative maintenance manuals are provided.
- Command relays are employed for controlling the functioning of module devices which include switching of power supply between modules in a scenario of failure.
- To add some more electrical security manual reset circuit breakers are used.
- All types of Check ups and measurements such as semi-annual Check up have check lists.
Frequently Asked Questions
Q1: Can you tell me what the Liebert CSU 3000 capabilities?
A1: With respect to your question, the cooling capacity is said to vary between five and thirty seven tons.
Q2: Kindly specify the available cooling methods with the chiller.
A2: This chiller has three methods to include air cooled, glycol cooled and water cooled.
Q3: Kindly elaborate what exactly does the Sentinel 3000/Alarm Monitor does?
A3: The Sentinel monitors the system’s operation, triggers alarms for system malfunctions already mentioned such as high temperature and low flow of water as its features and automatically shifts to standby modules.
Q4: Let us know how is the flow switch used?
A4: The flow switch is a safety feature that will turn the chiller module off redundantly if the water flow is stopped for more than 10 seconds and sets off an alarm while powering another module for backup.
Q5: What type of maintenance should one follow for this chiller?
A5: A suggested maintenance would be to conduct Frequent Preventative maintenance which includes taking action in leaks, physically checking for refrigerant present and cleaning the outdoor unit partially, furthermore it would also be advisable to follow the check lists provided brimming with monthly and semi annual check up tasks.
Q6: Is it possible to customize the cooling?
A6: It is, the chiller has a capacity selector switch embedded allowing changes to be made in accordance with how low or high the atmosphere is need for the operational circumstances.
Q7: What is the result of a compressor failure?
A7: In the event that the lead module malfunctions, the system is equipped with relay controls that are able to redirect electricity to a backup module. As a result, the system continues to operate.
