Pfening Logo Proof Boxes, Retard Rooms and Fermentation Rooms

For over 60 years, Pfening Proof Boxes have set the industry standard for reliable consistent proofing.

Proof Box 8 lanes wide

The room is a rugged construction to give years of trouble-free service.

  • Aluminum structural frame for rigid, rust-free enclosure
  • 1 1/4" thick Polyurethane insulation wall panels for minimal thermal loss
  • Attractive aluminum or stainless steel wall casings for long life

The venting system is Pfening's Equi-Temp ™ air conditioning system, specifically designed to virtually eliminate atmospheric variations from floor to ceiling and wall to wall throughout the box. The result is consistent size, texture, and appearance of your raised dough product

The control is the Pfening Model B Digital Microprocessor Control to accurately maintain temperature between 25-122º Fahrenheit and relative humidity between 35-100% for a more consistent product.
