Heatcraft Worldwide Refrigeration uses natural 

refrigerants with low GWP to develop leading 

technologies for the supermarket and industrial 

markets. Transcritical CO


 solutions, such as the 



Boost, were launched in Europe at the beginning 

of this year with outstanding results and customer 

reception. CO


 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



based refrigeration systems can reduce energy 

consumption by up to 20% 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.                                                                                                                                      



 – Solar Energy Solutions 

We harness the power of the sun to significantly 

reduce electricity use with the SunSource



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 



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.

Harness the sun’s 

power to reduce 

heating and cooling

bills by half.
