EDPM Rubber Tube
The DELTA-TUBE™LD EPDM rubber tube heating system heats the greenhouse
at the soil level where the heat is needed. Heat rising from the bed
warms the soil and plant roots. By controlling the soil temperature both
rooting and plant growth can be accelerated.
in Ground Heating
Growers that use our ground heating systems have shown 30% reduction
of fuel usage along with shorter production times and superior product
quality. This material excels in the nursery industry for general growing
and rooting of cuttings and is ideal for starter houses. Growers that
this material for heating soil or nutrient bags of tomatoes and cucumbers have shown a 50% increase
in yield. Grape growers have found a quicker and more even callusing
pattern by using bottom heat to callus grape stock.
DELTA-TUBE EPDM rubber tubing is ideal for use in
a hot water heating system due to its resistance to temperature and
chemicals and its superior
heat transfer capabilities. Small tube design reduces the system water
volume and enables it to respond quickly and efficiently. Tubing spaced
4 to 6 inches apart provides even temperatures to the soil and the
crop for optimum environment of all types of growing.
The Delta Tube manifolds use a unique plastic fitting that is pressed
into the PVC pipe creating a water tight fit that is guaranteed not
to leak. Each fitting is pressed into the top of the manifold so that
the tubing is easily installed. Each manifold is custom manufactured
for each system.
The exclusive tubing spacers secure the Delta T tubing at the optimum
design spacing. They are cut to the bed width for ease of installation.
Maximum length is 8 foot.
The hydronic heating system is the DELTA-TUBE™ LD EPDM rubber tube
system using 135°F water temperature and will consist of the
- 1.5" Manifolds with plastic adapters pressed fit into SCH 80
PVC pipe cut to the bed width. All fittings shall be installed on
manifold for easy connection of tubing.
- Ridged plastic spacers with
spaces every 2 inches holds the EPDM tube in place and space tube
on 10 foot spacing. Spacers are cut to bed
width up to 8 foot long.
- High quality EPDM rubber tubing 0.30" ID x 0.45" OD
shall be on inch centers. Tubing shall be able to resist ozone, chemicals,
fertilizers and temperatures up to 230°F. Tubing shall be provided
on 1,000 foot spools for easy handling.
Some of the many advantages of the DELTA-TUBE™ LD systems are:
- Direct contact from tubing to root zone for
maximum soil and plant temperature control.
- Even temperatures are maintained throughout the system
resulting in even crop growth.
- Compatible with any type of hot water
- Different temperature zones for flexible growing.
- Cost effective
system for the grower that wants to get into a hot water
heating system inexpensively.
- 1.5" plastic manifolds make it easy to install
on plastic mainlines.
- Special pressed fit barb fittings installed
on top of manifold make installation of tubing neat and quick.
ridged spacers can easily be installed without having to install
more than two or three fasteners.
- High quality tubing withstands
UV light, fertilizers, and high temperatures.
- Flexible tubing is easily
installed and comes in 500 foot rolls.
