Benefits

Bosch CL Series

The CL Series comes equipped with a compact cabinet designed to fit most commercial replacement projects. This single-stage unit is available in ½ to 6-ton size range and meets or exceeds ASHRAE 90.1 efficiency standards. Outfitted with the latest in compressor and heat transfer technologies, as well as being available with optional ECM Constant Torque or ECM Constant Airflow blowers, this product performs extremely well in both water loop and geothermal applications.

Serviceability

The CL features a swinging electrical box, which provides convenient access to the compressor and other internal components. Additionally, vertical units include better air coil serviceability and a slide out blower to make servicing the blower and internal components a breeze.

Quiet Operation

Units come standard with a unique sound package designed to eliminate vibration transmission to the cabinet and reduce unwanted noise. The product is designed with a blower wheel that helps keep discharge air noise to a minimum.

Cabinet Configuration Flexibility

CL horizontal cabinets come standard with blower systems that are easily reconfigured on the job site. The blower discharge arrangement can be changed from end to straight through discharge in only a matter of minutes.

Low Global Warming Potential

These highly efficient units not only reduce your operating cost, but also reduce carbon dioxide emissions, a leading cause of global warming. Equipped with R-454B refrigerant, the Bosch CL Series WSHP has a low global warming potential (low-GWP) of 466, meeting the criteria of the AIM Act.
