ZETA Sky M HP (Heat Pump)

High efficiency Heat Pump for 2-pipe, 4-pipe, and Domestic Hot Water applications with R-454B refrigerant. 30-300 Ton Capacity

Strengths:

  • 30-ton modular units; banks of up to 10 modules for systems up to 300 tons
  • R-454B low-GWP refrigerant with dual refrigerant circuits for staged capacity
  • Designed for cold climates and built for year-round performance, with an ambient operating range from -4°F (-20°C) to 125°F (52°C)
  • Delivers chilled water down to 40°F (4 °C) and hot water up to 140°F (60°C), with an optional 34°F (1°C) glycol-free cooling
  • Supports simultaneous heating and cooling in 4-pipe applications
  • 24/7 cellular remote program monitoring for performance visibility and service support
  • Engineered, manufactured, and tested in the U.S.A. Complies with Buy America and BABA

The Zeta Sky M HP Heat Pump is an all-electric air source modular heat pump 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 heating and cooling demand as building needs evolve.

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

Heating, Cooling, and Domestic Hot Water:

  • Supports 2-pipe, 4-pipe, and domestic water heating configurations
  • Delivers hot water up to 140°F (60°C) for domestic/hydronic applications while supporting chilled water down to 40°F (4°C)
  • Optional low-temp heat exchanger available for 34°F (1°C) glycol-free cooling
