This system grows with your requirements and offers a simple design for easy initial and future installation. Reaches efficiencies up to 16.3 EER at full-load and up to 21.3 EER at part-load (IPLV), exceeding ASHRAE 90.1 minimum efficiency requirements. The model UCW has earned AHRI® certification, an assurance of this product’s performance.
Tonnages: 15, 25, 30, 50, 70, 85
Configurations: 30 - 1,000 tons per bank
A dedication to energy and environmental leadership results in the Ultimate Chiller Solution modular design and fundamental features: compact size, redundant operation, maneuverability, efficiency, reliability and serviceability. Available in 15, 25, 30, 50, 70 and 85 tons which, when combined, tonnages can obtain specific project turndown and capacity requirements from 15 to 1,000 tons per bank while having the ability to accommodate future growth and expansion needs.
Heavy gauge G90 galvanized steel base and framework with 3 mil powder coat paint finish, baked at 350°F for resilience in transport and installation. Schedule 40 carbon steel pipe water headers are designed to connect to adjacent modules through the use of 300 psi rated grooved couplings.
High efficiency design offers up to 16.5 EER at full-load and up to 21.3 EER at part-load (IPLV), exceeding ASHRAE 90.1 minimum efficiency requirements.
Incremental and minimum overall per ton refrigerant charge. Largest refrigerant circuit contains approximately one pound per ton of charge per module. This typically eliminates the requirement for expensive refrigerant monitoring, ventilation and associated controls. Non-ozone depleting R-410A refrigerant offers better efficiency, higher capacity and utilizes superior synthetic lubricants for longer compressor life.
Integrated CoolLogic Control System
Each module has an independent control panel and simple two-conductor shielded daisy chain connection from the Master Panel to the modules ensuring ultimate performance with minimal field wiring. BAS interface with native BACnet, Modbus, Lonworks and N2 communications.
All modules fit easily through standard 36” doorways and onto typical freight elevators. Modules are designed with a low center of gravity and base cutouts for forklifts and pallet jacks.
Dual scroll compressors with independent refrigerant circuits provide reliable, efficient, quiet and redundant operation. Use of highly efficient, dual circuit brazed plate heat exchangers offer maximum performance at both full-load and part-load conditions.
Design allows easy access to major components such as compressors, brazed plate heat exchangers, refrigeration components and pete’s ports. Unique design is fully serviceable and maintainable without removal of module from the chiller bank or disassembly of headers.
Separate module electrical feeds provide true electrical redundancy. Dual independent refrigeration circuits per module provide true mechanical redundancy. Major application flexibility and expandability. Photo shows three 70 ton modules totaling 210 tons capacity. The 15, 25, 30, 50 and 70 ton modules are configurable up to 400 tons per bank. The 85 ton module is configurable up to 1,000 tons per bank.
Options for every application.
Automatic Strainer Package
Field installed high quality stainless steel filtration system with minimum 60 mesh stainless steel screens. Available options include pressure differential alarm and automatic time flush.
Condenser Water Head Pressure Regulating
Control Factory installed motorized condenser water valves provide head pressure regulation for low entering condenser water temperature applications (less than 60°F).
Factory installed reverse cycle heating and cooling operation compatible with boiler/tower and geothermal systems.
Factory installed option that provides hot water, as high as 135°F, while simultaneously producing chilled water for the chiller system.
Hot Gas Bypass
Factory installed on both circuits allowing unit operation below the minimum step of unloading.
Field installed to increase efficiency and ensure long life of the equipment with Y-style and basket strainers of cast iron 200 psi or carbon 275 psi with 60 mesh stainless steel screens. All strainers are field installed external to the chiller bank for ease of service.
Pressure Differential Flow Sensor
Field installed to prevent operation of the chiller without sufficient water flow to the evaporator and/or condenser.
Variable Speed Compressor
Factory installed variable frequency drives provide more precise water temperature control and optimum part load energy efficiency.
Water Header Bypass
A field installed water header bypass may be utilized to prevent deadheading the pump.
Water Isolation Valves and Flush Ports
Factory installed to provide isolation to the module for maintenance and cleaning of evaporator and condenser heat exchangers. This is accomplished without increasing unit or bank dimensions while adjacent modules continue normal operation. Optional choice of integral manual or motorized valves includes ¾” fill and flush valves.
