Features & Benets

Innovative

Thermo-Flex

™

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 “ex” 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 of fers a f ive -year l imited guarantee against leaks at tub e sheets and center supports for all medium prole unit coolers.
