Econofrost 9000 Series
The 9000 series retrofit cassette night cover is the “workhorse” of the supermarket industry. Known for its durability, performance, and ease of use, the Econofrost 9000 series is designed to retrofit to any display case. It is the only night cover tested by Southern California Edison and is proven to save 36% energy, that would otherwise be used by the case, for every hour it is used.
The unique fabric of the Econofrost 9000 series consists of a woven aluminum foil laminated to a polyethersulfone backing for strength, hygiene, and flame spread resistance. The laminated fabric is sealed with a polyethylene clear coat that exceeds UL94HB requirements, prevents accumulation of dirt, dust and stains, and is easily cleaned with a mild detergent for optimum hygiene. The fabric is perforated to exacting standards to prevent formation of condensation, and is laser cut or reinforced on outer edges with a fiber material to prevent excessive wear.
The retraction system is a spring/brake assembly made using food-safe oiled steel for long life and anti-corrosion, mounted to a steel shaft that connects the patented braking system. The spring/brake assembly is engineered to provide smooth, controlled retraction every time, and is tested and certified by Econofrost factory engineers for 7,000 retractions/rewinds or 20 years of use.
