Engineering the cold chain your production line can't run without.
The refrigeration cycle
How a refrigeration plant works
Every plant we build runs on this cycle. Refrigerant is compressed into a hot, high-pressure gas, releases heat as it condenses to liquid, drops pressure through the expansion valve, then absorbs heat again as it evaporates. Getting each stage right — sizing, materials, controls — is the difference between a system that lasts 15 years and one that doesn't.
About AJM
Refrigeration know-how, not just refrigeration equipment.
PT. Adi Jaya Mandirindo (AJM) specialises in the design, supply, installation, commissioning and after-sales support of commercial and industrial refrigeration plants.
Founded in 2014 as a refrigeration applicator, our team combines know-how in thermodynamics, fluid dynamics and mechanical engineering with both synthetic and natural refrigerants — so every plant we hand over is built for reliability, efficiency and the lowest realistic cost of ownership.
Our Mission
Deliver tailored refrigeration solutions for the food & beverage, chemical & pharmaceutical, oil & gas and marine industries.
Our Vision
Become a world-class refrigeration company built on eco-friendly, sustainable engineering.
How We Work
From load calculation to long-term uptime.
The same five stages, every project — because skipping one is where refrigeration plants fail.
Thermodynamic load calculations and system design matched to your production line — not a catalogue template.
Certified components sourced from world-leading compressor, condenser and controls manufacturers.
On-site installation by engineers who understand refrigerant handling, insulation and piping standards.
Full system commissioning, pressure testing and performance verification before handover.
Ongoing maintenance and support to protect uptime long after installation day.
