Demand Flow Retrofit for Air-Cooled Chillers – EKG M&E Sdn Bhd

At EKG M&E Sdn Bhd, we offer professional demand flow retrofit solutions for air-cooled chillers, helping you upgrade existing systems to operate more efficiently, responsively, and intelligently. By introducing variable flow technology and smart controls, we transform conventional fixed-flow chiller setups into energy-saving systems that dynamically adapt to real-time demand.

What Is a Demand Flow Retrofit?

A demand flow retrofit modifies your current air-cooled chiller system to enable variable water and refrigerant flow, based on actual building or process cooling requirements. It involves upgrading hardware (like pumps and fans with VSDs) and control logic to improve energy efficiency, performance, and equipment life—without replacing your entire chiller plant.

What’s Included in Our Retrofit Service

• Variable Speed Drive (VSD) Installation
  For chilled water pumps and condenser fans to allow flexible, energy-efficient operation.

• Compressor Staging Optimization
  Adjust control logic to reduce short cycling and balance compressor loads across all operating conditions.

• Delta-T and Flow Control Tuning
  Optimize the chilled water temperature differential and pump flow to prevent over-pumping and improve heat transfer.

• Expansion Valve Calibration or Upgrade
  Adjust or replace TXVs/EXVs to regulate refrigerant flow during fluctuating demand.

• Sensor Installation and Control System Upgrade
  Integrate temperature, flow, and pressure sensors with PLC or BMS systems to enable adaptive real-time operation.

Benefits of a Demand Flow Retrofit

• Save up to 30–40% on energy costs

• Improve chiller efficiency and part-load performance

• Enhance cooling stability and zone temperature control

• Extend the life of compressors, fans, and pumps

• Reduce maintenance frequency and operational downtime
