Industry Requirements at a Glance

Each sector imposes distinct thermal, regulatory, and reliability constraints. This comparison helps identify the critical parameters for your application.

Industry Temperature Range Key Standard Redundancy Typical Capacity
Food & Beverage -40°C to +4°C HACCP / ISO 22000 N+1 compressors 200 - 2,000 TR
Pharmaceutical -80°C to +8°C GMP / GDP / 21 CFR Full redundancy + backup power 50 - 500 TR
Data Centers +7°C to +18°C chilled water ASHRAE TC 9.9 N+1 with auto-failover 100 - 2,000 TR
Cold Chain -30°C to +15°C GDP / ATP Multi-circuit backup 50 - 1,000 TR
Commercial +5°C to +12°C chilled water ASHRAE 90.1 / 55 Varies by criticality 100 - 3,000 TR
Industrial +7°C to +80°C process ATEX / TEMA / ASME Continuous operation rated 200 - 5,000 TR

Selection Considerations & System Limitations

Choosing the right thermal system requires understanding the trade-offs involved. Below are key factors our application engineers evaluate during project scoping.

Air-Cooled vs. Water-Cooled Chillers

Air-cooled chillers offer lower installation cost and zero water consumption, with COP range 2.8-3.5. Water-cooled alternatives achieve COP 5.0-6.0 but require cooling towers and water treatment. For installations above 500 TR, water-cooled systems typically deliver lower total cost of ownership over a 15-20 year lifecycle.

Natural vs. Synthetic Refrigerants

Natural refrigerants (R-744, R-717, R-290) offer zero or near-zero GWP. CO2 transcritical systems require up to 120 bar operating pressure. Ammonia is toxic above 300 ppm and restricted in occupied spaces. Synthetic HFOs offer drop-in compatibility but carry higher cost and patent fees.
