Available in sizes from 1 to 20 tons, the new HydroMarine heat pump line from Delta Hydronics is efficient, simple to operate, and easy to install in chilling and heating applications for aquaculture and aquatic life support.

At the heart of HydroMarine™ design is a robust commercial grade titanium tube evaporator. The evaporator is a two-pass counter flow design using a tightly rolled Gr-2, 0.035” wall titanium helical coil housed in a schedule 80 PVC shell. This innovative evaporator shell design offers a tangential water inlet which accelerates water around the exterior of the coil on the down flow that is opposite to the refrigerant up flow; then water reverses direction in lower shell spiraling upward inside coil to complete a second pass. At high water velocities the tight coil design provides a uniform flow distribution with continuous self-cleaning of the tube surfaces.
Delta took a hard look at the basic reliable titanium aquatic chillers currently on the market and improved the base construction materials, aquatic flow dynamics and general serviceability over the common schedule 40 PVC shell, single directional flow and baffled titanium evaporator designs. The HydroMarine™ 6” & 8” diameter evaporators will accommodate flows at 120 and 200 gpm respectively with pressure drops less than 10 fthd (4.3 PSI).

On the service side of the equation, HydroMarine’s™ dual flanged evaporator allows for simple inspection of coil by loosening the union connections and unbolting top flange without the need of pulling the shell off the coil. Periodic cleaning can be simplified using a hose, pressure washer or optional tube brush and flushing of bottom drain with coil inside the vertical shell.
The HydroMarine™ integrates both residential and commercial Carrier condensing R-410a units for temperature control applications down to 48°F and utilizes commercial Husseman-Krack R-407a refrigeration units for aquatic chilling temperatures down to 35°F applications.
The HydroMarine’s™ base construction utilizes non-corrosive FRP grating with 316SS evaporator mounting brackets and 316SS hardware providing a durable and low-profile wind stability design which enables easy rigging using a pallet jack. The finishing touch on this equipment package is the 0.50” closed cell insulation that is jacketed with a shiny 24-gauge 316SS wrap protecting insulation from the elements and normal wear.
