Polar King International secured Miami-Dade County Product Control  approval for its walk-in coolers and freezers through June 2027. The company  said it received the certification extension by meeting stringent requirements  and passing extensive impact testing.
Miami-Dade County initially issues its approval for Polar  King units in 2017.
By satisfying the standards for compliance with the Florida  Building Code and Miami-Dade County, Polar King coolers and freezers are  accepted for use in high-velocity hurricane zones, the company said. Compliance  with the county’s building code demonstrates the quality of the seamless  construction methods used to manufacture Polar King’s walk-in units. 
The Miami-Dade County Product Control approval number is NOA  No. 21-0914.04.
All Polar King walk-in coolers and walk-in freezers are  manufactured with an unfaced, closed cell polyisocyanurate foam encased in  fiberglass, both inside and out, according to Polar King. This construction  method and insulation material provides superior R-Values and lower maintenance  costs. The seamless exterior also ensures cost-effective operation, even in the  most intense heat. Tested above 175 degrees F, Polar King’s fiberglass design  is a suitable choice for warm weather climates such as Florida.
