Special Project Case Studies
Case 1: Chiller for Hyperbaric Chamber
Challenge: Cooling a hyperbaric medical treatment chamber operating at 6 atmospheres of pressure.
Solution: Special chiller with a heat exchanger designed for high pressure, redundant control system, and materials compatible with a hospital environment.
Result: System in operation for 5 years without failures, serving patients daily.
Case 2: Refrigeration for Wind Tunnel
Challenge: Maintaining a constant temperature of 20°C ±0.5°C in a wind tunnel for aerodynamic tests, with a variable thermal load from 0 to 500 kW.
Solution: Modular system with 4 chillers of 50 TR, capacity control by frequency inverters, and advanced automation for rapid response to load variations.
Result: Temperature precision of ±0.3°C, allowing high-quality tests.
Case 3: Mobile Refrigeration Unit
Challenge: Developing a container-mounted refrigeration unit to serve civil construction sites in remote locations.
Solution: 30 TR chiller in a 20-foot container, with its own generator, water tank, and remote control system via satellite.
Result: Unit operating on construction sites in the Amazon, providing chilled water for dam concreting.
Case 4: Refrigeration System for Particle Accelerator
Challenge: Cooling superconducting magnets of a particle accelerator with water at 4°C ±0.1°C.
Solution: Cascade refrigeration system with two stages, high-precision PID temperature control, and full redundancy.
Result: Critical system for scientific research operating with 99.99% availability.
