  • Engineered, manufactured, and tested in the U.S.A. Complies with Buy America and BABA

The ZETA Sky M CH Chiller is an all-electric air-cooled modular chiller designed to reduce system complexity while supporting flexible capacity. Each 30-ton module can operate independently or as part of a bank of up to 10 modules, allowing systems to expand up to 300 tons with internal headers and a variety of valve packages and piping accessories available.

Its modular design gives owners, engineers, and facility teams a flexible path to phased capacity, build redundancy, and match cooling demand as building needs evolve. ZSC series are available with optional integral free-cooling coils to produce chilled water at low ambient temperatures rather using the refrigerant circuit.

Modular Capacity:

  • 30-ton modular design for flexible system sizing
  • Banks support up to 10 modules for systems of 300 tons
  • Staged capacity helps match performance to changing load demands
  • Single-point electrical connection helps simplify installation and reduce electrical maintenance complexity
  • Modular configuration supports phased installations, redundancy, and future expansion

Reliable Cooling:

  • Available with Integrated free-cooling coils.
  • Produces leaving chilled water down to 40°F (4°C), refrigerant circuit can operate in cooling mode as low as 0 °F (-18°C), or in free-cooling mode as low as -15 F (-26 °C)
  • Optional low-temp heat exchanger available for 34°F (1°C) glycol-free cooling
