Block Ice Plant Components

Freezing Tank
Freezing tanks as a rule are too large for shipment, so they are shipped as pre-cut steel sheets, complete with structural steel bracing, grid supports and grid guides for welding at the job site. Standard tank metal thickness is 3/16" (4.8mm). Small tanks are factory assembled.

Evaporative Coils
Brine cooling coils are a special CESA design, built in separate sections, utilizing square tubing headers for Schedule 40 (3.15mm) wall runners. Each section is tested at 100psi (7.03kgs/sq. cm) air pressure while submerged in water, and again at the same pressure when sections are assembled.
These coils are unique in that the sections are assembled on the correct centers to accommodate a wide variation of brine flow. The flow required for the ice freezing cans can then be accommodated by a variation in the section spacing. Each coil is designed for one particular plant, for high heat transfer capability.
Coils are for flooded type ammonia, direct expansion for R-22. A correctly sized accumulator with electric liquid level control is supplied for ammonia, a thermal expansion valve with distributor and electric shut off valve is supplied for R-22.
This type of cooling coil is incomparably the best heat transfer surface ever devised for large volumes of liquid to be cooled.

Grids
Cans are normally grouped together in steel grids for lifting with the ice crane. The grids are fabricated from structural steel and plate. Metal thickness and weight vary according to plant tonnage and can size. Painted grids are standard, galvanized grids are available at extra cost.

Agitators
Because of the critical relationship of volume, velocity, friction head, heat transfer rates and efficiency, the agitators use impellers, V-belt driven for precise control of speed, ball bearings for axial and side loads at the shaft pulley end and a bronze guide bearing at the propeller end, submerged in the cold brine, assuring many years of trouble free life. Motors are totally enclosed, with replacement motors available around the world.

Cans are made for block weights in both kilogram and pound sizes. While we can supply almost any size can, common sizes are of 300, 150, 100, and 50 lbs., or 150, 75, 50 and 25 kgs. The kilo sizes are 10% longer than the pound sizes, other dimensions being the same. Cans are fabricated from galvanized steel sheets, with machine welded seams. Generally the sheet is 16 gauge (1.6 mm) for the sides and bottoms. 14 gauge (1.99 mm) bottoms are used in larger can sizes. Galvanized steel bands are welded to the tops of the cans for lifting.

Can fillers are supplied to fill from one can to ninety cans simultaneously. Individual compartments, one for each can, insures accurate metering to each can. All material in contact with water is galvanized steel. Individual filler spouts are supplied for each can. Float valves are supplied for fillers for 12 cans or less, float switch and electric valve for more than 12 cans. A structural steel platform is supplied for wall mounting or for customer supplied supports.

• Air Agitation
  Includes air blowers, laterals for grids with the necessary connecting hoses, check valves, drop tube for each can, core sucker pump, core sucker and hose, core refiller, and hose, and air headers (for clear block).
• Covers for Cans and Brine
  In most cases we find our customers are able to make their covers locally, for which we supply the necessary drawings. Made from yellow pine or fir, the 3/4" wood is treated with linseed oil for moisture protection, and corrosion resistant fasteners and lifting eyes are used.
• Crane
  Cranes will vary from hand pushed cranes with electric hoists to fully motorized cranes, hoists and trolleys complete with all necessary accessories including crane rails and suspended "walking" controls.
• Can Dump
  A pivoted platform for removing ice from the cans, and operated by the ice lifting crane. The dump is fabricated from structural steel, and lined with wood to protect the cans.

Refrigeration Systems

For plants of 15 tons or less, we can supply reciprocating compressor units or semi-hermetic compressor packaged condensing units. For larger plants we can supply industrial screw compressor units.
