Holdover Plates

FEATURES ---------------
True Eutectic Solution
  • Specially formulated mixture of water, salts and inhibitors.
  • Provides stable box temperatures throughout holdover period.
  • Injected into plates under a vacuum (30 microns).
  • Four temperature ranges available: 0F (-18C), -9F (-23), and -18F (-28C) for freezer application and 26F (-3C) for refrigerator application.
Unique Stainless Steel Construction
  • Hand polished #304 stainless steel (.062) for clean, aesthetic appearance.
  • Easy mount flange system on short side of all plates.
  • Internally gussetted steel tubing improves thermal transfer and is high pressure tested to 550 lbs.
  • Hand welded seams by certified TIG welders.
  • Wide variety of sizes and ranges to accommodate various box designs.
Dual Circuit Design
  • Permits paralleled operation for engine drive and AC or DC voltage condensing units for redundancy.
  • Retrofit crossover assembly for easy conversion to single unit.
  • Rapid ?pull down? of plate temperature when run with a double pass on one condensing unit.
  • Dual set of thermostat sensing wells for accurate temperature control.

* Plates can be mounted in either horizontal or vertical configurations, with connections either at right, left, up or down. Refrigerant line connections are always located on short dimension of plate.
** Dimension includes two 3/4? (1.9cm) flanges with 1/4? (6.35mm) diameter mounting holes.
*** All plates can be prefabricated to customer?s requirements, including copper stubs, flare connections and fittings, crossover assemblies and SwagelockTM fittings.
Installation Guidelines for Holdover Plates
When choosing the proper plate sizes, primary consideration should be given to calculated BTU loads as well as box design and usage. Any special requirements must be determined prior to selection and installation. area of the plate to provide proper performance. A minimum of 5/8? (1.6cm) clearance between the box and the back of the plate is recommended.
