G-Class air-cooled chillers

G-Class is an optimal solution for applications requiring quiet, efficient cooling.

Smardt’s G-Class of chillers is distinguished by its use of environmentally-friendly refrigerants having ultralow GWP ratings.

30-520 TR (105-1830 kW)
R513A, R515B and R1234ze

Revolutionary low-noise operation with high efficiency

When noisy cooling systems are a big concern, Smardt provides the optimal solution: G-Class air-cooled oil-free chillers.

A chiller that knows when to hush

Smardt G-Class sound ratings are typically below 85 dBA at 1 meter. That’s about 20 dBA lower than conventional air-cooled screw chillers—almost 25% quieter.

The Smardt G-Class is well suited for installations where excessive noise is not permitted at certain times; e.g. residential neighborhoods at night. The system’s Active Noise Control feature allows you to limit the chiller’s sound output during specific periods of operation.

40% more efficient than ASHRAE code demands

Variable speed enables the  Smardt G-Class chiller to  precisely match capacity with greater energy efficiency.  In comparison to ASHRAE® 90.1-2016,  Smardt G-Class oil-free air-cooled chillers have Integrated Part Load Values (IPLV) over 40% more efficient.

What’s more, Smardt’s Free-Cooling* integrates special bypass circuitry, controls, and safeguards. Our optional Free-Cooling package can dramatically increase G-Class chiller efficiencies–at low ambient temperatures.

*Available on Smardt G-Class AD design series chillers

G-Class is an optimal solution for applications requiring low GWP refrigerants and quiet, efficient cooling, for office towers, greenhouse facilities, cold climates, and data centers.

Key features and benefits:

An abundance of cost saving measures

Older variable-speed screw chillers require a large footprint on the roof top. They are noisy and energy intensive.

Smardt G-Class oil-free air-cooled chillers, by comparison are extremely quiet. They are also highly efficient, especially at part load. The result: is lower power consumption when running your Smardt chiller. Pay back your investment within 2 years or sooner.

Your investment in any Smardt oil-free magnetic bearing chiller provides:
