Holdover Plates

What are Holdover Plates or Holding Plates?

Holdover plates are stainless steel tanks which contain an evaporator coil surrounded by a liquid solution.  As the compressor runs, this solution freezes.  Once the compressor turns off, the frozen solution continues to absorb heat from the refrigerated box thereby extending the "off" cycle of the compressor.  When incorporated into a properly designed system, holdover plates can significantly reduce average energy consumption.

RParts holdover plates are available in a variety of sizes and may be used as a direct replacement for many of the name-brand manufacturers including as Crosby, Grunert, Technautics, Sea Frost, Nautic-Kold, Technicold and Dole.  If you are designing your own system, use RParts holdover plates in place of a traditional evaporator to give your system the ultimate in energy efficiency.

We offer these holdover plates pre-filled and sealed or empty and ready for your own solution.  Propylene gycol is available by the gallon if you want to mix your own solution.  See our chart for glycol mixing ratios.

To purchase a filled holdover plate, select the fill option on the "More Info" page before adding the holdover plate to the shopping cart.  If you don't select a fill option we will ship the plate empty.

Key features:

  • #304 stainless steel plate construction.
  • Non-toxic propylene glycol solution.
  • Continuous (seamless) copper coil ensures no possibility of internal leakage.
  • Dual-circuit (except #018-0101) permits parallel operation of engine drive and AC or DC condensing units for redundancy.
  • Connect crossover for easy conversion to single circuit use.
  • Easy-mount flanges provide 0.50" standoff for improved air circulation.
  • Variety of sizes to accommodate various box sizes and applications.
  • Choice of two temperature ranges +24F (refrigerator) and 0F (freezer).
