Delta Star Air-Cooled Heat Pump

Delta Star Air-Cooled Heat Pump

The Delta Star Air-cooled Heat Pump packs a lot of heating and cooling power into one neat little unit. A convenient and reliable solution for all your heating and chilling needs, our quality titanium construction outshines our competition, making our heat pumps the best choice for use with both fresh and saltwater. Plumb in-line using an external pump to move water through the heat exchanger and over the refrigerant cooled coil.

  • Maintains water temperatures in the range of 40° – 85°F
  • Oversized helical titanium coil in the heat exchanger maximizes BTU transfer efficiency.
  • TITANIUM is the only HEX material proven to be 100% fish and coral safe in saltwater systems.
  • Quiet, internal, spring mounted hermetic motor/compressor provides years of reliable service.
  • Low profile and compact design allows for easy placement in tight places.

System Requirements:

  • An external pump is required with Delta Star Heat Pumps to move water through the heat exchanger.
  • Observe min/max flow rates critical to heat pump operation in ‘Specifications’ table
  • Heat pump must not be placed in a confined space, as restricted air flow will limit the efficiency and lifespan of the chiller unit. Do not restrict airflow by placing unit in a cabinet or closet.
  • Delta Star heat pumps must be placed indoors. Option for outdoor use with purchase of ‘Outdoor Kit’

    Properly sizing your Delta Star Heat Pump

    A number of factors influence the correct size of heat pump required for your application. While standard Btu calculations can be applied, and our Heat Pump Specifications can offer some guidelines, the parameters of your application will be the deciding factor in correct size selection.

    Things to consider…

    Home Aquariums: The life support equipment on your aquarium contributes excess heat to your
    system, including pumps, filters, and lighting. Tank material, surface area, plumbing, and sumps
    also play a role, as do a number of other seemingly small details. Give us a call and our
    experienced technicians will ask the right questions about your set-up to get the answers we need
    to size the right unit for you.

    Aquaculture/Hatcheries: Beyond the LSS equipment, these systems can be vast and varied in their
    set-up, from small indoor hatcheries to huge outdoor fish farms. With so many specific factors to
    consider, we are here to help size the right heating and chilling equipment. We have heat pumps,
    chillers, heat exchangers, and boilers of every size, so give us a call and tell us what you want to
    achieve and we’ll get you exactly what you need.

    Hydroponics: Typically hydroponics applications have a relatively low water volume spread out over
    a large area, which means a tremendous amount of heat may be gained or lost. Grow lights and
    sunlight contribute significantly to water heat and encourage growth fungal growth and disease
    that can be harmful to plants. Our heat pumps or chiller can help maintain the optimal growing
    water temperature so you can maximize your yield. Call us for assistance with proper sizing.

    Outdoor Kit: Includes a heat pump cover rated for outdoor use, and low ambient controls. Kit must be purchased separately. All of these units are made to order so please request Outdoor Kit at time of ordering. Can also be ordered at a later date but will require installation by the end user.
