REFRIGERATION 

Heatcraft Worldwide 

Refrigeration uses natural refrigerants with low 

GWP to develop leading technologies for the 

supermarket and industrial markets. Transcritical 

CO

2

 solutions, such as the eCO

2

Boost, were launched 

in Europe with outstanding results and customer 

reception. CO

2

 technology in refrigeration has been 

found to be 1,300 to 4,000 times less impactful on 

the climate than HFC-type refrigerants. Also, CO

2

-

based refrigeration systems can reduce energy 

consumption by up to 20 percent in most applications. 

These technological advancements demonstrate 

Heatcraft’s ability to consistently satisfy customer 

and regulatory requirements, while displaying a 

commitment towards preserving the environment 

through sustainable solutions.

SUNSOURCE® – 

SOLAR ENERGY 

SOLUTIONS 

We harness the power of the 

sun to significantly reduce 

electricity use with the 

SunSource® Energy System. 

Lennox continues to innovate and offers solar-

ready heating, cooling and refrigeration solutions 

for residential and commercial customers. Our 

SunSource systems significantly reduce energy 

consumption for homes, commercial buildings and 

refrigeration systems. In commercial applications, the 

SunSource

 

rooftop system can help building owners 

achieve net-zero energy status, as the SunSource 

system can generate more power than the rooftop 

HVAC unit consumes. In refrigeration applications, 

the SunSource Energy System is designed to help 

grocery retailers and other commercial refrigeration 

customers reduce energy consumption during peak 

demand hours resulting in substantial energy savings.
