Mr. Ron Conry - Creator of modular chillers

Beginning of Modular Technology
Mr. Ron Conry, an engineer of Multistack and also the creator of modular chiller. His expertise in the field of refrigeration and air conditioning with 20 years of working experience in both Australia and USA in the same industry.

He has broken through the limitation and inconvenience from traditional large chillers, working out the ideal "Wish List" for cooling system.

  • Compact and space-saving
  • Easy installation and operation
  • Peak economy at all loads
  • Reliable and maintenance friendly
  • Add-on flexibility

MULTISTACK is the creator and leader of modular chillers since 1985, MULTISTACK has improved modular technology through unremitting efforts.

MULTISTACK is the pioneer in innovation and environmental protection and being the expert in modular solutions.

MULTISTACK has engineered, manufactured, and distributed an impressive array of modular air conditioning chillers.

  1. FIRST to use plate heat exchanger on a chiller
  2. FIRST to integrate microprocessor controls on a modular chiller
  3. FIRST to built-in water strainer into a chiller
  4. FIRST to install auto back-flushing device
  5. FIRST in the world to research on magnetic levitation oil-free technology on centrifugal compressor
  6. FIRST variable water flow type modular chiller
  7. FIRST modular (heat pump) chiller
  8. FIRST modular heat recovery type chiller
  9. FIRST modular chiller using magnetic levitation oil-free centrifugal compressor
