ABOUT YOUR NVT-3/9 

The NU-VU

®

 NVT-3/9 is an electrically powered and operated commercial baking/cooking appliance. It does not 

require exterior venting under normal circumstances; however, hood and venting requirements vary from country 
to country, state to state, and even from locality to locality. For this reason, NU-VU

®

 cannot give specific detailed 

information regarding your individual application. Your local building inspector, licensed contractor, or installer is 
best qualified to determine your specific needs. 

The  oven  section  of  the  NVT-3/9  features  our  patented  V-AIR

®

  air  movement  system.  A  top-mounted  blower 

moves  the  air  down  through  the  side  walls  to  be  heated,  then  out  through  specially  designed  hole  patterns  to 
provide even heat distribution throughout the oven. Your product is baked evenly from top to bottom, side to side, 
front to back without turning pans. You can load the oven completely with pans having the same product, bake, 
and remove the entire load at the same time. The bake is uniform because each shelf now receives essentially the 
same air pattern. 

The oven compartment can hold up to three (3) full size 18"x26" (457mm x 660mm) sheet pans, or six (6) half-
size 13"x18" (330mm x 457mm) sheet pans on the included stainless steel wire shelves. 

The proofer compartment can hold up to nine (9) full size 18"x26" (457mm x 660mm) sheet pans, or eighteen (18) 
13"x18" (330mm x 457mm) half-size sheet pans on the included stainless steel wire shelves. A total of twelve (12) 
stainless steel wire shelves are included for use in the oven and proofer. 

Measuring 77¾” (1975mm) high, 36½” (927mm) wide and 30 ¾" (781mm) deep, the entire unit takes up less than 
8 square feet (0.75 square meters) of floor space. It is constructed of stainless steel both inside and out. The front 
and back frames are cut from single sheets of stainless steel. These frames then are welded to the stainless base 
and top headers to form a unit with superior durability and rigidity. Components such as temperature and humidity 
controls, timers, switches, motors, heating elements, and others are thoroughly tested before shipment. Ongoing 
research and development projects are used to introduce the latest and most dependable components. 

The NU-VU

®

 NVT-3/9 is designed for: 

 

• 

Automatic pan positioning 

• 

Dependability 

 

• 

Rapid and even baking 

• 

Low energy consumption 

 

• 

Easy cleaning 

• 

Low maintenance 

 

• 

Simple operation 

• 

Rapid servicing 

The 

AUTOMIST

  option  eliminates  the  manually  filled  water  pan  in  the  proofer,  but  requires  connection  to  a 

pressurized  potable  water  supply.  An  adjustable  water  mist  is  injected  into  the  blower  wheel  in  the  rear  of  the 
proofer. The blower wheel then distributes this water mist evenly throughout the proofer compartment to provide 
the controlled humidity necessary for proper proofing action. 

 

IMPORTANT: This appliance is not intended for use by persons (including children) 
with reduced physical, sensory or mental capabilities, or lack of experience and 
knowledge, unless they have been given supervision or instruction concerning use of 
the appliance by a person responsible for their safety. 
 
Children should be supervised to ensure that they do not play with the appliance.
