Water Chiller | Central Unit | 80 Ton Air-Cooled

Water Chiller | Central Unit | 80 Ton Air-Cooled

TI-80A
  • These central chiller systems range from 20 to 180 tons of cooling capacity providing a coolant temperature range between 20°F and 70°F when using R-454B refrigerant.
  • The standard Central Chiller is configured with reservoir and pumps housed in a single frame – making it a complete self-contained package which reduces installation costs compared to other systems.
  • These central chiller systems are air-cooled requiring an outdoor remote condenser to reject the heat removed from the refrigeration circuit.
  • These central chiller systems can be configured for future expansion to meet your growing cooling needs with the addition of chiller modules.
  • The dual pump system features one pump dedicated to distributing coolant through the plant and a second internal re-circulation pump accommodating ever changing process flow demand.
  • The standard tank is a patented, one-piece, seamless, non-rusting rotationally molded reservoir made of a linear low density polyethylene and insulated with dense foam to minimize sweating and maximize system efficiency.
  • These central chiller systems use a non-ozone depleting refrigerant and are equipped with hermetic scroll compressors or tandem scroll compressors that utilize rotary technology for smooth, efficient operation.

Specification Notes:
  1. Since product innovation and improvement is our constant goal, all features and specifications are subject to change without notice or liability. Selection of certain optional features may change listed specifications.
  2. Cooling capacity: Rated tons at 12,000 BTU/hr/ton @ 50°F LWT Operating at temperatures below 50° will reduce chiller capacity. The minimum recommended operating temperature when no glycol is used is 48°F.
  3. Ambient conditions for condenser: Loss of capacity and/or difficulty operating may occur at higher ambient temperatures. The minimum recommended ambient temperature is -20°F.
  4. Field charging by user required.
  5. Dimensions are approximate and should be confirmed with the factory prior to construction planning.
