Following a highly successful launch of its 1 to 30 ton Variable Speed Air Cooled Chillers, Delta T Systems has expanded the application of this new technology to a line of 2 to 30 ton Variable Speed Water Cooled Chillers.
Chillers maintain process temperatures by circulating water through a refrigerant cooled heat exchanger called an evaporator. This heat is then removed via an air or water-cooled condenser. Air-cooled condensers use ambient air to remove the heat where water-cooled condensers use a water source to remove the heat. Certain applications necessitate a water cooled chiller, often times to prevent the circulation of heated air within the facility. The Delta T Systems water-cooled chiller can be piped to a city water source or cooling tower water supply. In order to optimize chiller efficiency and temperature control with varying ambient and condenser water supply temperatures, it is best to use a variable or modulating control for the condenser heat removal. To achieve this, Delta T Systems chillers use a variable speed condenser fan on air-cooled condenser units and a modulating control valve on water-cooled condensing units. These condenser modulating devices coupled with a variable speed compressor, electronic expansion valve, and sophisticated controls allows Delta T Systems to provide the most efficient chiller in the market.
The integration of variable speed controls is a proven technology, yet in it’s infancy within process cooling applications. The main benefit of this new technology is a dramatic reduction in operating costs relative to fixed speed systems. Conservatively, annual energy cost reductions will equal 30% to 50%, which translate to operating cost reductions of $3,000 to $4,000 for a 10 ton chiller operating one full shift per day. That significant energy savings yields a full ROI of less than 3 years!
Delta T Systems new line of Variable Speed Water Cooled Chillers offers capacities that range from 2 to 30 tons and integrates variable speed compressors on all models.
The new water cooled chiller line offers these innovative features:
- Energy savings between 30% and 50% of the initial investment
- Tight temperature control within ½ a degree
- Stainless steel, copper brazed plate evaporator for reduced maintenance
- Hermetically sealed variable speed compressor technology
- Non-ferrous chilled water piping
- Smallest footprint in the industry
- Advanced control platform from the leader in HVAC and refrigeration controls
- Industry 4.0 ready
