Customer Q&A Ask a Question

How is this unit insulated?
For effective heat retention and moisture resistance, this unit is insulated with Extruded Polystyrene (XPS). XPS is less prone to molding, providing a longer life for your unit.
How does ambient room temperature influence the performance of this cabinet?
Ambient room temperature can affect the temperature of your food product at holding/proofing. Due to differences in ambient room temperature, you may need to monitor the proofing process and/or adjust the proofing temperature and humidity settings of your Avantco heated holding/proofing cabinet to achieve the desired results. You may also need to adjust the temperature of the water used to produce steam.

In proofing mode, once steam is generated from the water contained in the bottom water pan, adjustments can be made to release heat in order to reach the desired temperature. If you are trying to proof at low temperatures, the desired proofing temperature must be warmer than the ambient temperature in your kitchen.

This Avantco heated holding/proofing cabinet operates at the following temperatures in heat and proof modes:

Heat Mode: 80°F – 185°F
Proof Mode: 85°F – 115°F (30-100% Humidity)
What's the best way to ensure this proofing cabinet stays at the lower end of the proofing temperature and humidity range during use?
The proofing function of this cabinet works best when it’s filled to near maximum capacity. A greater amount of dough will absorb excess humidity, keeping the cabinet temperature at the lower range.
