1.2 Thermal Capacity: Each unit shall have a thermal storage capacity of _______ kWh operating with ___________refrigerant and a build time of _______ hours at a _______ °C nominal evaporator temperature.

1.3 Experience: Manufacturers submitting bids for equipment in this specification shall have a standard production model of this unit, which has been manufactured and in use for 3 years. The manufacturer shall offer evidence that the equipment has been successfully operated on a minimum of 50 applications, which utilize the same refrigerant and meltout arrangement specified.

2.0 Construction Details

2.1 Tank: The tank shall be constructed of heavy gauge hot-dip galvanized steel and reinforced with full-length structural angles underneath and on all four sides. All seams shall be welded to ensure watertight cnostruction. A zinc rich coating shall be applied to all exposed edges and welds.

2.2 Coil: The coil shall be constructed of prime surface serpentine steel circuits and shall be tested at 15 bar (31 bar for ammonia applications) air pressure under water. The coil shall be encased in a steel frame and the entire assembly hot-dip galvanised after fabrication. For use with Ammonia refrigerant, the coil shall be complete with purge connection for oil maintenance.

2.3 Insulation: Extruded polystyrene insulation shall be provided between the tank and the exterior panels. The insulation shall be 80 mm thick on the tank sides and ends, and 50 mm thick on the bottom and inside the covers.

2.4 Exterior Panels: Exterior panels sealed at all seams provide a complete vapour barrier and protect the insulation. They are furnished with B.A.C.’s exclusive BALTIBOND® Corrosion Protection System.

2.5 Covers: The ICE CHILLER® unit(s) shall be provided with sectional insulated steel covers provided with the BALTIBOND® Corrosion Protection System.

2.6 Ice Thickness Control: A sensing element shall be mounted on the coil to deactivate the refrigerant compressor at a full build of ice.

2.7 Air pump: Centrifugal regenerative blower for field mounting to supply low pressure air for agitation of the water. Pump is complete with a weather protected inlet air filter, and is suitable for outdoor applications.

2.8 Air Distributor: Low pressure air shall be distributed through multiple perforated PVC pipes.
