TERRALink™
Geothermal Heating/Cooling Systems
Top quality construction and materials:
TERRALink manifolds are made of solid copper, Grundfos or Taco pumps,
and solid brass mechanical components. With tough, reliable plastic loop
pipe, and quality EPA approved Alcohol based antifreeze. All packages
come with a full 1-year replacement warrantee Pumps, a 10 year
replacement warrantee on all other components, and a 25-year warrantee
(optional 50-year available) on earth loop tubing.
Ease of Design: TERRALink eliminates engineering calculations
required for pipe sizing, antifreeze concentrations, pump sizing and
trench length/depths as we do it all for you in a convenient,
Pre-Engineered Package. ART supplies specifications, detailed for your
project location and soil type with every package, to ensure your
projects success.
Flexibility of Loop Installation: TERRALink’s closed loop design
approach allows for any closed loop system to be installed.
Simple "Plug and Play" Start-up: TERRALink’s "plug and play"
manifolds require no flushing of loop lines or measured mixing of
antifreeze. With the loops pre-filled with the proper concentration of
antifreeze, simply connect TERRALink to a potable water supply, and the
system will automatically fill and purge itself,
Easy to handle: No more heavy coils of stiff, rigid tubing, which
are difficult to work with, TERRALink’s piping is thick walled, yet
pliable enough to be handled by a single person, and is sent pre-charged
with simple compression fittings to connect to the manifold.
Increases operating efficiencies and eases field loop troubleshooting:
Differing pipe lengths, trench depths, crushed or damaged piping,
backfill voids or differing sub soil conditions can cause some loops to
absorb more of the loads than others, decreasing the effective heat
saturation area, and causing heat pumps to work harder, and less
efficient. This is a problem common to most installations, and has been
found to reduce the operating efficiencies of units by 60%+, and in
extreme cases, renders the heat pump in-operational. TERRALink allows
for each loops flow rate to be adjusted to meet the peak operating
efficiencies of any heat pump, by allowing manifold balancing during and
after installation, to ensure the heat output of each individual field
loop is optimized. In extreme cases, individual ground circuits can be
shut off, allowing the HVAC system to continue to function to repair or
replace a partial or non-functioning loop.
Direct electrical connectivity: All units come with 230VAC pre-wired
pumps or can include 120 VAC with relays and standard receptacle plugs
(other voltages available), which can either be connected directly to
most heat pump manufacturers compressor relays, or through the 24 VAC
control circuits. (See individual heat pump manufacturers
recommendations for relay power requirements or alternate output
switching connections)
Lower Excavation Costs: The loops of plastic TERRALink tubing that
extend into the ground are not straight, but instead comprised of
spirals, known as a "slinky loop". The loops are sent in standard coil
lengths, which are often five to fifteen times longer, than current
straight line runs. In this way they may be extended through a longer or
shorter trench in the ground providing greater ground contact area. As
the tubing has a small diameter, this reduces the turbulence loss,
allowing for much longer pipe runs. As well, as the loops are
considerably longer, this allows for the fluid to remain in the ground
longer, which reduces the return water temperature difference from the
entering water temperature from the heat pump. This means more efficient
heat transfer to the soils over a greater contact area of excavation,
allowing for reduced trench lengths, while maintaining increased heat
transfer efficiency.
Expandable: TERRALink manifolds easily adapt for increased heat pump
requirements, add to loop, pump or heat pump manifolds quickly and
easily without draining or dismantling the existing TERRALink
installation, in less than one hour.
Adapts to any closed loop design possibility: Horizontal slinky
ground loops, including stacked loop runs, vertical single and double
closed well loops, and raft or coiled pond loop variations are
available, any closed, pond or earth multiple loop system design is
possible.
Multiple Heat Pump Capability: Installing more than one water source
heat pump? TERRALink was designed for flexibility with extension
balancing manifolds to meet any multiple unit requirement.
Eliminates costly fusion welding: With no field piping connections
underground or in inaccessible locations, the loop field bed has
absolutely no couplings or fittings, and are continuous to the interior
manifold. With standard brass compression fittings, and continuous field
loops, TERRALink requires no fusion welding. Fusion welding of poly pipe
is expensive and time consuming, requiring special knowledge and tools
to complete and requires pressure testing to ensure connections are
water tight.
Eliminates system flushing: TERRALink was designed for simplicity.
Simply plumb a potable water supply to the unit, and turn the water on.
The system will fill, and air will automatically purge from the system.
After a few minutes, simply turn on the pump(s), and TERRALink’s Micro
Bubble air eliminator removes any remaining air, ensuring that all air
is purged and continues to remove air during the life of the system. The
domestic water supply is protected with a certified dual check valve,
pressure relief valve, and pressure regulator ***some state codes may
vary and require additional safety measures***.
Eliminates antifreeze installation: With the loops already
pre-filled with the required level of concentrated antifreeze, TERRALink
eliminates the need to calculate, add or mix antifreeze in the system.
Allowing the pump(s) to operate for a few hours, mixes the antifreeze
with potable water sufficiently for unit heating operation.
Eliminate Guess work: ART supply’s design specifications for your
individual project for a variety of heat pump design efficiencies which
includes minimal design specifications. This allows for increased heat
pump design efficiencies simply by increasing trench lengths, depths or
spacing to lower seasonal ground or pond loop returning water
temperature differences.
