Why FWE?

For decades, FWE has been trusted by foodservice operators for equipment that delivers exceptional durability, performance, and reliability.

Equipped with FWE's Moisture-Temp heat system, it offers separate temperature and moisture controls for holding conditions. This unit includes a removable 12" x 20" water pan for manual humidity control and accommodates a variety of tray configurations.

For a complete list of tray capacities and spacing configurations, refer to the chart on page two of the spec sheet.

FEATURES

Agency Approvals
CE - The CE mark is mandatory for products sold in the European Economic Area. It indicates the product conforms with certain manufacturing and design safety requirements. CE is similar to UL except it's more of a declaration by the manufacturer that the product meets the relevant rules, rather than being the mark of independent testing.
NSF - NSF International (formerly known as the National Sanitation Foundation) is an independent, non-profit organization that certifies food service equipment and ensures it is designed and constructed in a way that promotes food safety. FWE products that meet these standards bear the NSF mark.
You may also see a designation that a product meets NSF/ANSI, which adds rules from the American National Standards Institute to the testing. ANSI works closely with NSF to develop its food safety standards and complete testing to those.
CUL - C-UL mark indicates a product meets the CSA testing standards for Canada.
C-UL-US mark indicates a product meets the UL and CSA testing standards for both the United States and Canada.
UL - The UL mark, which now serves customers in more than 100 countries, has become the authority on product safety. Its engineers test for things like soundness of design, safety of electrical components, and structural integrity of products for which UL listing is sought.
If you think of NSF International classification as protection for your customers, then the mark of Underwriters Laboratories (UL) indicates safety for those who work in your commercial kitchen. The Illinois-based testing agency assures that the equipment that gets its stamp operates safely. There is also a sanitation classification that offers similar assurances about food safety as the NSF mark. Products are indicated as "Classified UL-EPH."
Bumpers
No Bumper - No bumper
Caster
3.5" Casters - 3.5" Heavy-duty casters - polyurethane casters are long lasting and used for easy maneuverability, even when fully loaded
All Swivel Casters - All swivel casters allow for greater maneuverability. Great for tight turns or severe corners (such as on and off trucks or narrow hallways).
A drawback to the all swivel configuration is that it is harder to control the direction of the equipment when rolled in a straight line.
Mobile
Construction
Stainless Steel / Insulated - Constructed of stainless steel, with welded base frame for added strength and durability - fully insulated cabinet and door provide energy efficient heating and longer holding times
Control Panel
Moisture-Temps Controls - Easy to use - upfront and recessed electronic control panel has separate, easy to read and set, air moisture and air temperature controls
Electronic Controls - Electronic controls featuring easy to read digital display of cabinet temperature (with recall capacity of temperature set point and actual cabinet temperature), equipped with a programmable low temperature alarm, master ON/OFF switch with power indicator light.

Heat System
Moisture-Temp Heat System - High performance - low technology. Provide the best food quality from amplified heated moisture for short-term holding applications.
Heated holding some menu items, such as chicken, will become steamed or soggy by using a covered pan. When exposed to dry heat, uncovered, these items become dry and rubbery. Achieve best results with controlled moisture. The length of holding time is also extended.
Hinging
Field Reversible Hinging - Field reversible door- flexible installation options for kitchen layout
Hinges on Right Side - Right hand door hinging
Slides and Shelves
Adjustable Universal Slides Stainless Steel - Unique universal design holds 12" x 20" pans, 18" x 26" sheet trays or GN containers on fully adjustable stainless steel tray slides. Slides are removable for thorough interior cleaning

OPTIONS & ACCESSORIES

Bumpers

In this way, the bumper absorbs all the shock in transport, protecting the integrity of the construction.
Top Corner Bumpers - Top corner bumpers are a good option for those customers not needing the protection of a full bumper, but still require protection for walls and surrounding equipment.
