Keene KT10 Trommel updates. These are a few 3D drawings showing the plumbing system for the water motor set up. Just worked up a new larger 6" water drive motor that worked amazing. The goal was to be able to run the Trommel at lower pressure to turn the drum. ... See MoreSee Less

DWX 2.5” heat exchanger on the new Predator Max Performance 459cc 16HP engine, using a Keene P350 (4”x3”) pump. The price for this model heat exchanger is $800 (+shipping).
Other manufacturers and home builders use a single pass copper tubing design to build their dredge heaters. With that design, water from the dredge pump passes through a single coil of ¼” copper tubing inside a steel shell (fire extinguisher, steel pipe, paint can etc.) of the heater. Exhaust from the engine enters the shell and heats the outside of this copper tubing; heating the water. Not only is this design inefficient, it poses a substantial risk of the water flashing to steam and scalding the diver.
DWX heat exchangers are designed exactly opposite of this single pass copper tubing heater. DWX uses a tube and shell heat exchanger made entirely of 316 stainless steel. All fittings and hardware (except the strainer) are stainless as well. The shell of the 2.5" heat exchanger houses 19 internal 1/4" sealed stainless tubes through which the engine exhaust passes. Cold water from the pump first passes through a 50 mesh strainer then enters the shell of the heat exchanger through the 1" lower side port. Water circulates inside the shell and around the sealed exhaust tubes, heating the water. Hot water flows out of the top 1" port and the temperature is regulated by either opening or closing the 1/2" stainless valve; adjusting the flow. Each DWX heat exchanger is equipped with a 145°F thermal relief valve that will open and divert hot water out of the shell; stopping water flow to the diver. This ensures the diver isn't scalded with boiling water or steam if water flow from the pump is interrupted. The shell of the 2.5” heat exchanger holds 20oz of water. This volume of water is extremely unlikely to flash to steam even without the temperature relief valve. The clear pump feed hose and strainer cup show water flow and turbidity. Hot exhaust leaves the engine through a TIG welded stainless manifold then flows vertically thru the heat exchanger, exiting cold at the top thru the 1” muffler. The heat exchanger is stabilized and vibration isolated with a stainless clamp and support bar. The heat exchanger itself weighs only 2.5lbs (without strainer, exhaust manifold & muffler).
DWX heat exchangers are much more efficient (more hot water), more durable (stainless steel parts) and safer (temperature relief valve & greater water volume) than any single pass copper tubing heater. With 100's of hours of operation on a variety of engines/dredges, DWX heat exchangers are designed to give you years of trouble free operation. Why risk your safety with a poorly designed or home built wetsuit heater?

I made my own don’t need it now though lol
How much to ship the heat exchange to Australia??
Para perú se podría enviar
I used this in Alaska this season, the guy I had with me is currently still there using it. It provides nice heat, and has everything needed for the install.
I haven't seen that type of set-up before.
I like it.
We have been building the weed separation boxes for several years now. This type of de-watering box has proven to be a invaluable tool the dredging up weeds and other invasive plant species. ... See MoreSee Less
We have a weed control guy that does milfoil up here. Good idea.
Do you all think this would help us dredge our pond of weeds and willow sprouts?
What's the price on that table?
Well if it successful as their other products they have a winner
Fabricate yer own
Good work, guys.
Do you have a video of this ?
