Factory-Installed Parts
A 4-way reversing valve is installed.
Eliminated Parts
The Reverse cycle’s unique technology, coupled with the bi-flow electric expansion valve and drier, eliminates:
• Defrost coil heaters
• Check valves and expansion valves at the condenser that are normally necessary for traditional hot gas defrost
systems, although the 7.5 hp still uses check valve bypass loops
• Bypass valves
• Liquid line solenoid valves
• Receiver tanks
Defrost Time
Defrost time is greatly lessened with the reverse cycle option. The average time using electric defrost heaters is 20-30
minutes, but reverse cycle performs a completely “clean” defrost typically in 3 – 5 minutes for freezers and 1-1/2 – 2
minutes for coolers.
Because the defrost is so rapid, there is no noticeable increase in freezer room temperature and the product temperature
rise is also significantly less.
Reverse cycle defrosts, combined with demand defrost, assures the evaporator receives the number of complete defrosts
needed at the necessary times to prevent iced evaporators while assuring the protection of the valued product being
stored.
