Aqua Logic water cooled Delta Star Heat
Pumps offers the same reliability as our water cooled chillers but
with the added ability to heat your water as well. One unit handles
both the heating and cooling functions automatically in both
freshwater and saltwater applications. A properly sized and installed
heat pump will provide stable, thermostatically controlled water
temperature.
For Marine applications Aqua Logic’s Delta Star Heat Pumps feature
water cooled marine duty condensers, making them ideal for
installations with an existing saltwater supply. They use seawater to
cool the condenser instead of air provided by a fan and motor. Their
low heat emission, compact size, and quiet operation allow them to be
used in tight spaces with minimal ventilation.
These Heat Pumps are typically used at aquarium, aquaculture, and
research facilities located near the ocean and have the ability to
pump filtered seawater to the chillers. These are also ideal for use
on boats and other sea going vessels. The condenser is made of
titanium and PVC making it completely compatible for saltwater
applications.
Each unit includes titanium heat exchanger, water control valve for
the condenser, digital temperature controller and black ABS cover.
Available in sizes from 1/3hp thru 1.5hp Aqua Logic has a size and
configuration to meet your specific requirements.

Applications:
Delta Star Heat Pumps are designed to be
used in a wide variety of both saltwater and freshwater applications.
Home Aquarist and Public aquariums use them to maintain stable water
temperatures in display tanks and quarantine holding. Government
hatcheries and commercial Aquaculture operations use our chillers to
hold brood stock at the optimum temperature for spawning conditioning.
Research facilities have long depended on Aqua Logic Heat Pumps
because of their reliability and precision in maintaining a wide range
of temperatures for their experiments. In Hydroponics facilities our
heat pumps maintain optimum temperatures for the nutrient solutions to
minimize root dieses and maximize growth.

Guidelines:
When you install your heat pump properly
you will get many years of dependable service. These heat pumps can be
mounted outdoors. One of the most important things to keep in mind
when you position your heat pump is air flow. Fresh air flow should
never be restricted to the condenser and the air discharged must not
be restricted when it leaves the unit. As air passes thru condenser,
over time dirt and dust may accumulate so it should be placed where
you have easy access to it for periodic cleaning. The unit should not
be placed in a location where snows melt or rain water runoff from a
roof falls directly on the unit.
When in the heating mode cool air is
discharged from the condenser and condensation may start dripping so
it is recommended that the units be placed in a “drip pan” to prevent
damage to the surface it is located on. These heat pumps are designed
to be mounted indoors where air temperatures do not get below 55oF.
Delta Star Heat Pumps require a pump to
move water thru the heat exchanger at all times. Correct water flow
rates are critical for chillers to operate properly. Refer to the flow
rate and pump selection chart to select the best pump for your Heat
Pump. Always use an external pump as submersible pumps add heat to the
water.

Sizing:
Many factors will have an influence when
determining the size heat pump required for a particular application.
While standard Btu calculations will give you a good starting point
for sizing, many environmental and system design parameters must be
considered. While sizing charts can be helpful, one chart DOES NOT
work for all heat pump installations.
Sizing charts for marine reef tanks (under 1500 gallons) are based on
“typical” setups using the common life support equipment (LSS), such
as pumps, filters, and lighting. However, some tanks have more pumps
or higher wattage lighting then what might be considered “normal”.
This must be considered when looking at a sizing chart. The sizing
chart we provide for reef aquariums is based on many years of
experience and a typical tank setup.
The sizing charts for aquaculture system, large public aquarium tanks
and other fish holding systems are different then that of the marine
reef tank. These systems may contain just one large tank or multiple
tanks, located indoors in a controlled environment or outdoors in
direct sunlight, and every situation in-between. These systems may
require less hp per gallon than reef aquariums. Adding insulation and
thermal pane viewing windows will decrease the amount hp per gallon
required.
For hydroponics applications nutrient solutions need to be maintained
at an optimum. Although the volumes may seen small it is spread out
over a large area and there is a tremendous amount of heat input from
either grow lights or natural sunlight. This heat input is greatest
when plants are young but as they grow and start shading their growing
trays the heat input decreases. Due to the numerous variety of set ups
these systems can be difficult to size.
We provide a questionnaire that you can fill out and return to us for
help in sizing a chiller for your particular application. The more
information you provide the better.
As always we have a staff of technicians that are ready to help answer
any technical questions you may have.
