The Absorption Chiller.

An Alternative Energy Technology.

Rapidly escalating electrical rates.

Peak demand charges.

Refrigerant restrictions and compliance.

Environmental responsibility.

For those concerned about all of these issues - and who isn't today - absorption provides a viable alternative to the traditional electric chiller.

Cost Effective and Environmentally Responsible.

Absorption chillers not only deliver efficient, continuous cooling with minimal use of electricity, they also use water as the refrigerant, not the fluorocarbon refrigerants used by mechanical vapor compression chillers. Yet, they can be used in the same wide range of settings - hospitals, schools, libraries, retail facilities, office buildings, industrial processing, and more.

Heat-Driven Cycle.

The basic absorption cycle, while similar to vapor compression in that both employ an evaporator to vaporize refrigerant and a condenser to return the refrigerant to its liquid state, does differ in its method of "compression." Absorption utilizes a thermal or chemical process which takes place in the absorber and generator section of the chiller. In the absorber, a lithium bromide solution absorbs low-pressure refrigerant water vapor produced in the evaporator. Operation in a deep vacuum causes the water to evaporate at low temperature, providing the refrigeration effect necessary to produce chilled water. The now diluted lithium bromide solution is pumped to the generator where heat is added to boil off the refrigerant, supplying vapor to the condenser. Refrigerant liquid returns to the evaporator while reconcentrated solution returns to the absorber to complete the cycle. Depending on configuration, reconcentration can occur in one or more stages.

A Money-Saving Alternative Energy Choice.

Absorption eliminates high electric costs and demand/ratchet charges because it uses economical natural gas, steam, hot water or various forms of waste heat as an energy source.

A life-cycle cost analysis, which considers purchase, installation, maintenance, and operating costs, often shows that absorption chillers are less expensive to own than electric chillers. What's more, because they fall under the "gas cooling" classification, absorption chillers typically qualify for utility rebates and incentives in many areas of the country - either to help reduce peak consumption of electric power, or in an effort to utilize abundant natural gas reserves in summer months.

Quiet, Reliable, and Easy to Maintain.

Relatively few moving parts make absorption chillers inherently reliable and less subject to mechanical failure than vapor compression chillers. You'll save time and money on service and inspection. Low sound and vibration levels allow installation close to occupied spaces, even on upper floors, without compromising occupant comfort.

Carrier Sets the Standard… Again.

Over half a century ago, Carrier Corporation began intensive research and development efforts on the absorption-cooling cycle that led to the first commercially manufactured units for large tonnage applications. Today, Carrier continues to lead the way with a variety of absorption chiller products and ongoing development of existing and new products.

Carrier Two-Stage Design Enhances Operating Efficiency

Cost-Effective Cooling.

The Carrier 16JT double-effect high-pressure steam chiller incorporates both a high- stage and low-stage generator, resulting in two stages of solution reconcentration. In this configuration, the low-stage generator acts as the condenser for the high-stage generator, increasing unit efficiency by over 70% as compared to a single-stage unit. High-efficiency operation with steam rates of less than 10 lb/hr-ton provides lower operating costs. And with today's increased emphasis on operating cost and efficiency, the 16JT is a winner in anyone's book.

An Extensive Capacity Range.

Spanning a 100- to 1700-ton nominal capacity range, the 16JT assures a perfect match for any building's cooling requirement and system configuration. Choose from 31 model sizes with various options and accessories.

For New or Retrofit Applications.

More and more, cost-conscious owners and operation managers are replacing aging electric chillers or single-stage absorption chillers with more efficient two-stage units. In both retrofit and new applications where access is tight and space is limited, the option of two piece shipment makes rigging and installation faster and easier.
