  • Cold plates are filled with a saline eutectic solution that is chemically mixed to freeze at a specific temperature.
  • The plates have a thickness of 1.5” and the length and width vary depending on the cabinet on which it is used.
  • The solution that fills the plate cannot be adjusted to hold another temperature once it is made.
  • Cold plates cannot be exchanged once the cart is built, nor can they be removed from the freezer.
  • The number and size of cold plate(s) depends on the customers desired holding temperature and the cabinet size.
  • To use, plug the unit into a regular 115 volt outlet and run overnight. Prior to transporting to your event, unplug the freezer and go make money! You can expect ten to twelve hours of holding power in 90 degrees before you will need to plug in and recharge.
  • Cold plate cabinets are built with condensing units and evaporator coils. When the cabinet is plugged in, the condensing unit sends refrigerant through the walls by way of the copper evaporator coils and it freezes the walls. The cold plates have refrigerant lines inside that freeze the plates.
  • Cold plates attached to the walls freeze by contact with the help of a mastic glue-type material.
  • Another type of cold plate offered is a re-useable cold pack. These plates are constructed with plastic exteriors and sold at different holding temperatures. The cold plate must be flat (horizontal) when placed in a cabinet in order to freeze. To entirely freeze the cold pack, 24 hours is required at -20 degrees. Your cart size will determine how many cold packs are needed, but two sets are suggested due to the length of time required for optimum use.

Our mobile carts contain digital thermostats and can be adjusted to any desired temperature when plugged into an electrical source. However, the set point of the cold plate cannot be altered, it can only be bypassed by using the digital thermostat when plugged in.

Every Health Department in every county has different regulations for vending and store operations. You should prepare to answer these questions when inquiring about mobile food vending permits:

  • What product will you be vending?
  • Do your products contain dairy or non-dairy? Pre-packaged or dipping? Are you selling or sampling?
  • Where will you be located? Mobile or a fixed location? If your proposed venue has a common commissary, let your Health Department know. They may not require a sink attached to the cart.
  • We have drawings and specs you can download and submit to your Health Department that will help speed up the process.

Verify with your Health Department to see if you need a hand-washing sink or a utensil washing sink. You may need one or both attached to your cart. We can customize our carts to accommodate your needs.

  • Press the SET key and hold until the temperature settings displays and begins to flash (2 seconds), then release.
  • Use the up and down arrows to select the new temperature desired.
  • Press and release the SET key: The display will return to show the temperature of the freezer.
