Yes 



it's the 



McKEE 



Highest type of Vacuum Pump made. 



—the one perfect system of vacuum heating. 

 Perfect because it operates with, not against, 

 the laws of nature. You are growing for 

 profit, you have no time to experiment, a 

 breakdown in your heating system would 

 entail a heavy loss. That is why the McKEE 

 vacuum system is yours by natural selection. 



The McKEE vacuum trap is designed to handle rough 

 work. The best heating system yet evolved will develop 

 dirt from the pipe joints. An ordinary trap cannot han- 

 dle this satisfactorily. The McKEE can— that's what 

 it's built for, and it's the only steam trap designed and 

 built exclusively for greenhouse heating. The McKEE 

 quickly relieves the system of cold air and water when 

 steam is suddenly turned into a lot of cold pipes. Hence 

 there is no danger of twisting pipes or injuring the sys- 

 tem. The McKEE can be installed in the coldest 

 weather. No necessity of stopping your plant.
