Honda case study
Magcat reduced scale, cut energy use, and lowered running costs for Honda’s compressor cooling system.
Client: Honda
Region: Thailand
Application: Cooling water for compressors
Sector: Manufacturing
Product: Magcat water conditioner
Honda has operated in Bangkok since 1965, producing automobiles, motorcycles, and power tools for the Asian market. At its manufacturing plant, a bank of 220 kW air compressors and dryers provides compressed air for production processes. These systems generate large amounts of heat, requiring continuous cooling with circulated water.
The challenge
Despite the installation of a costly softening and chemical dosing system, scale continued to form inside compressors and pipelines
Heavy deposits led to frequent maintenance, downtime, and reduced system reliability
Circulating pumps experienced pressure losses of 68%, resulting in an increased workload and energy demand
Ongoing costs included chemicals and salt, frequent descaling, part replacements, and higher electricity bills
The solution
A Magcat conditioner was installed on the feed line to one compressor during a six-month trial. Engineers collected baseline data before installation and monitored scale formation, pressure losses, and pump performance throughout the trial.
Results
Pressure losses reduced from 68% to 45% within four weeks
Pump energy consumption dropped by 6.6%, cutting electricity costs
Existing scale deposits began to break down, restoring heat exchanger efficiency
Magcat removed the need for chemicals, reduced maintenance labour, and lowered overall running costs
