TURBO ice makers inherently operate efficiently as chillers. You don't need a separate evaporator section, additional, refrigerant control valves, a large refrigerant charge or complex controls.

Harvesting ice makers are extremely efficient ice-source heat pumps. Heating with ice can be substantial side benefit or it can be the primary function. Because ice is not stored on ice-making surfaces, the system can operate continuously-which means uninterrupted delivery of heat.

Typical compressor and condenser operating temperatures provide attractive coefficients of performance. By taking advantage of time-of-use electric rates now available from most utilities, heating with ice-source heat pumps can be significantly less expensive than burning oil or gas.

The system provides an ideal answer for day cooling/night heating... or summer cooling/winter heating. Winter ice inventories can easily be managed by solar melting, waste heat melting, discharge to river or pond, or by physical removal. Design flexibility is unmatched by any other system.

With other systems, to handle increased cooling loads you need more compression and heat transfer equipment. With TURBO ice harvesting, you only need a bigger ice storage tank. The tank can be located indoors, outdoors, underground-anywhere that will allow mounting of the mechanical package above the storage tank. Tanks can be concrete, steel, fiberglass-whatever works out most economically for your requirements.

With other ice-storage techniques, suction temperature drops throughout the ice-building period. Lower suction temperature means reduced capacity, and higher energy consumption. With TURBO ice-harvesting equipment, suction temperature is relatively constant since sections harvest sequentially, improving efficiency and extending compressor life.

Turbo's packaged unit concept eliminates extensive field assembly and ensures single source responsibility to optimize components resulting in the most economically installed and operating system.

All the ice needed to meet cooling requirements during an on-peak period is produced and stored during the previous off-peak period. Typically ice is produced at night and melted the following day. Demand charges are avoided entirely.

Only part of the cooling needed for an on-peak period is provided by melting ice produced during the previous off-peak period. The rest is supplied by on-peak operation of the ice make as a chiller. Demand chargesare greatly reduced, but not totally avoided.

Here's where Turbo's ice harvesting system excels beyond any other thermal storage system. Particularly with buildings that are closed nights and weekends. That's because every weekend hour is productive. Ice is produced during all off-peak hours, including Saturday and Sunday. The ice is stored and gradually melted as needed over the course of the week. Demand charges are totally avoided.

Another strategy where TURBO harvesting ice makers are unequalled. All on-peak and off-peak hours weekdays and weekends are fully utilized to obtain 168 hours of compressor operation per week. Although not totally eliminating demand charges, this option often yields a very attractive return on investment.
