equi-temp

For over eighty years the Fred D. Pfening Company has been at the forefront of proofing technology, providing the most high-performance and rugged box in the industry. Our boxes incorporate polyurethane insulation, limiting thermal loss. Heavy-duty, durable doors protect against the demands of day to day use. Boxes are available in stainless steel and aluminum.

Pfening’s unique Equi-Temp air system virtually eliminates temperature and humidity variations within the box, resulting in consistent size, texture, and appearance of raised doughs, wall to wall and floor to ceiling. Our proof boxes can be customized to any configuration the customer desires. We can enlarge or modify any rack proof box whether built by us or others.

We offer a wide range of control options from a digital micro-processor to PLCs tailored for individual needs. All Pfening controls use Vaisala sensors to maintain temperatures up to 122 degree (better to have degree symbol) F, and relative humidity up to 100%. See cut sheets of our B4, C, and C2 models.
