The UL873 standard approved by Underwriters Laboratory sets
specific functional and life cycle standards for equipment used in
temperature regulation as it pertains to refrigeration applications.
UL873 insures the equipment will maintain safe and proper
operation in commercial refrigeration environments.
Competitive electric timer products use a different standard
UL917. The UL917 standard is rated for clock-operated time
controls not commercial refrigeration defrost timers. Paragon
Universal Defrost Products are the only multi-voltage defrost
controls rated to UL873 standards.
How does the UL873 differ
from UL917?
As the standard relates to Paragon and competitive defrost
controls, Paragon controls rated to UL873 are tested and
certified to last five times longer at 4 defrosts per day, than
timers rated to UL917 standards.
