Chiller Plant Operations

High-Tonnage Cooling for Mission-Critical Operations.

From plastic injection molding to pharmaceutical cold-chains, industrial chillers run 24/7. We provide comprehensive descaling, oil analysis, and PLC diagnostics for screw, scroll, and centrifugal chiller plants.

Technical Capabilities
  • Shell-and-Tube Chemical Descaling
  • Compressor Oil Acidity & Viscosity Analysis
  • Electronic Expansion Valve (EXV) Stepper Motor Tests
  • Chilled Water Flow Rate (GPM) Calibration
Industrial SLA

We operate across Chakan, Ranjangaon, and Wagholi MIDCs with 4-hour response times for critical manufacturing plant breakdowns.

Fault Code Library

Common Chiller Plant Operations error codes and our diagnostic response protocols.

Carrier / Trane

Low Evaporator Pressure

Low refrigerant, restricted EXV, or poor water flow

Action:Check water pump pressure differential and strainer.

High Condenser Pressure

Fouled condenser tubes or high entering water temp

Action:Perform chemical descaling on condenser tubes.

Oil Pressure Fault

Clogged oil filter or failed oil pump

Action:Replace oil filter and check compressor sump heater.

Preventive Maintenance

Our standardized operating procedures (SOPs) for routine maintenance.

  1. Log Approach Temperature (Difference between leaving water temp and refrigerant saturation temp).
  2. Clean Y-strainers on both evaporator and condenser water loops.
  3. Megger test compressor windings (500V/1000V DC) to check insulation resistance.
  4. Verify the operation of flow switches to prevent freeze-ups.
Case Study Highlight

Plastics Manufacturing, Shirur

25% Energy Efficiency Gain

Performed deep chemical descaling on a 200TR water-cooled chiller's condenser, reducing the approach temperature from 8°C back to the factory 2°C, drastically dropping compressor amp draw.

Frequently Asked Questions

Q. What is an 'Approach Temperature' in a chiller?

It's the difference between the leaving water temperature and the refrigerant temperature. A high approach indicates poor heat transfer, usually due to scale buildup in the tubes.

Q. How often should chiller oil be replaced?

Oil should be tested annually for acidity and moisture. It usually requires replacement every 3 to 5 years, or immediately after a compressor burnout.
