Innovative

Coil Design

Bohn’s innovative coil design utilizes a 

unique approach to coil expansion that 

virtually  eliminates  the  possibility  of 

leaks at tube sheets and coil supports. 
The thermo-Flex™ coil design for the 

unit cooler* allows the coil to “flex” during 

periods of defrost resulting in expansion 

of the coil surface. By eliminating the 

possibility of wear at critical stress areas, 

the integrity and longevity of the unit 

are dramatically increased. The result is a 

product which greatly enhances overall 

system  reliability  and  reduces  risk  of 

costly refrigerant loss.
Bohn  offers  a  five-year  limited 

medium profile unit coolers.
