LBC Proofers
Our roll-in proofers work fast and efficiently, yielding even proofing with full loads or partial loads.
Essential for uniform proofing of a wide variety of products at varying temperatures and humidity levels
Roll-In Rack Proofers and Pass-Through Proofers
LBC proofers are built with durable components and with reliable, easy-to-use controls.
Proofers improve productivity and quality in baking breads. LBC proofers make the process of proofing easy and consistent, keeping uniform temperatures throughout the racks and even, constant airflow.
- Easy-to-use controls located in the door at eye level
- Four channel timers
- Accurate settings for temperature and humidity
- Single door, double door, triple door
LBC proofers are available in single door, double door and triple wide models in depths starting from 30″, Proofers with doors on one end are available in sizes up to 120” deep. Pass-thru proofers are available in sizes up to 240” deep.
LBC’s climate control system is fast responding and circulates air throughout the proofer for best results.
The available water treatment system can handle most water conditions and reduce maintenance costs for years.
Cartridges last an average of 6 months before needing to be changed.

What size of proofers are available?
Proofers are supplied in four widths and multiple depths in 10-inch increments. The widths of proofers are 38.5″, 58.4″, 75.5″, 102.5″.
Can I get a pass-thru proofer?
Yes, most any size proofer or retarder can be configured as a pass-thru. Contact your sales representative to discuss sizes and capacities.
Does the proofer need to be vented?
Proofers and Retarder/Proofers do not need to be vented and do not need hoods.
Can a proofer be installed on a wood floor?
The proofer can be installed on a wood floor, but due to water condensation, a wood floor is not recommended.
Can I get a proofer with a Stainless-Steel floor?
Yes, most models have an optional floors.
What is the difference between a proofer and a retarder/proofer?
Proofers provide an environment that is heated and humidified for promotion of fermentation. Retarder/Proofers also provide heat and humidity for fermentation, but also provide cooling to slow down fermentation. Retarder/proofers cool and then heat alternately and can be programmed to transition from cooling to heating.
What utilities are needed for my proofer?
Proofers and Retarder/proofers require 208 VAC or 240 VAC single phase or three phase, water and drain
What kind of filter do I need on my proofer?
Water treatment requirements vary from one area to another. The primary objective is to keep Chlorine levels low and to ensure that minerals will not form deposits on heating elements, sensors, and stainless-steel components. This can be accomplished in most cases with a Carbon Block filter and Lime Scale inhibitor, available from LBC. Some locations may require alternate methods of water treatment.
What if my water is softened?
Softened water is not recommended, since softening involves the injection of high levels of salts into the water. Salts are Chlorides that can deteriorate both stainless Steel components and the water lines supplying water to the proofer.
Does a proffer include installation, start-up and training?
Installation, Start-up and Training are not included with the proofer or retarder/proofer. They can be purchased at the time of purchase of the equipment, or an authorized installer can be contracted by you to install the appliance. For more information about Installation, Start-up, and Training, contact LBC Service Department.
Is the refrigeration system in the Retarder pre-charged or does it require a refrigeration mechanic?
Most retarders can be purchased as pre-charged are with R448A refrigerant. In some cases, the size of the components is too large to be pre-charged and a mechanic is required to complete installation and charging. Models that can be shipped pre-charged are LRPR1 40 thru 110, LRPR2N-30 thru 80, LRPR2S-30 thru 70, LRPR3-30 thru 50.
How LBC Proofers and Retarder/Proofer ship?
All LBC Proofers and Retarder/Proofers ship in crates for assembly on site. All crates can pass through a standard 3′ doorways. Call LBC sales for weights and dimensions.
Are LBC Proofers and Retarder/Proofers UL listed?
All LBC proofers and retarder/proofers are listed by ETL Intertek (Edison Testing Laboratories) and are tested and approved to UL197, ANSI Z83.11, NSF Standard 2 and equivalent Canadian Standards. ETL is recognized by all building officials in the US and Canada.
