At EKG (Malaysia) 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.
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.
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.
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
Support green building compliance and ESG goals
Commercial buildings with variable cooling demands
