4. RO Membrane Housing

• SS or FRP pressure vessel

• Designed for safe high-pressure operation

5. RO Membrane

• Semi-permeable membrane

• Separates pure water from dissolved contaminants

6. Post-Treatment System (Optional)

Working Principle of 500 LPH SS RO Plant

Raw water enters the pre-treatment system, where suspended particles, chlorine, and organic impurities are removed. The pre-treated water is then pressurized by a high-pressure pump and passed through the RO membrane.

The RO membrane allows only purified water molecules to pass through while rejecting dissolved salts, heavy metals, and contaminants. The purified water (permeate) is collected for use, while the rejected impurities are flushed out as reject water.

An Offline Chiller Plant is a centralized cooling system designed to operate independently of real-time automation, internet connectivity, or remote monitoring platforms. The system is controlled through local panels, manual controls, and standalone PLCs, making it highly reliable in locations where continuous connectivity or advanced automation is not required.

Offline chiller plants are commonly used in industrial facilities, commercial buildings, hospitals, malls, manufacturing units, cold storage, hotels, and process cooling applications. The plant produces chilled water (typically 5–7°C) which is circulated to air handling units (AHUs), fan coil units (FCUs), or process equipment to remove heat.

The plant emphasizes robust design, ease of operation, and maintenance, ensuring consistent cooling performance even in harsh or remote environments.

MAIN COMPONENTS OF OFFLINE CHILLER PLANT 1. Chiller Unit

• Core component that produces chilled water

• Available in air-cooled or water-cooled types

• Consists of compressor, evaporator, condenser, and expansion device

2. Compressor

• Compresses refrigerant to enable heat transfer

• Types: Scroll, Screw, or Reciprocating

• Selected based on capacity and application

3. Evaporator

• Heat exchanger where chilled water is produced

• Absorbs heat from circulating water

• Usually shell-and-tube or plate type

4. Condenser

• Rejects heat from refrigerant to air or cooling water

• Air-cooled condensers use fans

• Water-cooled condensers use cooling towers

5. Chilled Water Pumps

• Circulate chilled water from chiller to load (AHUs/FCUs/process)

• Generally centrifugal pumps

• May include standby pump for reliability

6. Condenser Water Pumps (For Water-Cooled Systems)

• Circulate water between condenser and cooling tower

• Essential for heat rejection

7. Cooling Tower (Water-Cooled Chillers)

• Rejects heat to atmosphere

• Helps maintain condenser efficiency

• Available in FRP, RCC, or metal construction

8. Electrical Control Panel

• Houses MCCBs, contactors, overload relays, timers

• Local start/stop controls

• Protection and safety interlocks

9. Piping Network

• Chilled water and condenser water piping

• Includes valves, strainers, flexible joints, and insulation

• Designed to minimize pressure drop

10. Expansion Tank

• Accommodates water expansion due to temperature changes

• Maintains system pressure balance

11. Air Handling Units (AHUs) / Fan Coil Units (FCUs)

• End-use equipment where cooling is delivered

• Transfers chilled water cooling to air or process area

12. Instrumentation & Gauges

• Temperature gauges, pressure gauges, flow indicators

• Enable manual monitoring and system diagnosis
