The Simrell: Hydro with its water piece handle

01 · Desktop platform

Made for Water and Dry Pipes

The Hydro is our microdose desktop platform, built for anyone who prefers their thermal extraction through a rig.

It pairs our titanium extraction chamber with a surgical stainless steel thermal assembly, and it runs on a torch or an induction heater. No batteries, no chargers and no firmware.

02 · Thermal system

A Stainless Thermal Assembly, Reengineered

We reengineered the stainless steel thermal assembly for the Hydro, and it makes the Hydro the easiest Simrell to learn. Aim your torch at an indicator and wait for the clicks. There's no need to spin it, so every session is easy to repeat, with heavier, denser hits.

  • Low and high-temperature audible indicators
  • Three visual heat zones
  • Increased airflow
  • Optimized heat retention
  • Works with a small single-flame torch up to a Blazer Big Shot
  • Induction heater compatible

03 · Heat zones

Pick a Zone and Wait for the Click

Each indicator on the heat exchanger gives you a different style of vapor. Pull at the first click for a lower temperature, or wait for the second for a higher one.

  • Top indicator: a looser pack and a medium to large torch for convection-leaning vapor.
  • Middle indicator: a medium pack for hybrid vapor, and the best place to start.
  • Bottom indicator: a tighter pack and a small single-flame torch for the densest, conduction-heavy vapor.

With a large torch like a Big Shot, don't aim below the middle indicator, and pull at the first click.

04 · 14mm integration

A True 14mm Threaded Connection

The Hydro's surgical stainless steel 14mm adapter threads onto the chamber, so the fit is stable, secure and built to last.

It was designed from the ground up for rig use, through a water pipe or a dry pipe.

Take the Engine With You

Pair the Hydro's Stainless thermal assembly with a Titanium Vortex or Heritage stem when you want something more portable.

Stems are sold separately.

Change Your Assembly, Change Your Extraction Experience

Our Classic Titanium, Titanium Convection and Stainless thermal assemblies all thread onto this same chamber. Change the assembly and you change how your Simrell heats, without buying a new device.

Extraction

“Dab With Flower”

Like the rest of the Simrell line, the Hydro vaporizes the trichomes on the flower without setting the plant material on fire.

You get concentrate-level intensity from flower, with more control over your dose and less reliance on costly extracts.

Heat the flower. Vaporize the trichomes. Leave the plant material intact.

guide

The Hydro parts numbered 1 to 6 in a row, with diagrams for the four assembly steps

Parts List

1 - Thermostat Discs

2 - Stainless Steel Thermal Capacitor (Convection Insert)

3 - Titanium Extraction Chamber (Bowl)

4 - Stainless Steel Heat Exchanger

5 - 14mm Water Piece Adapter (WPA)

6 - Handle

Assembly

Step 1 - Stack the thermostat discs (1) on top of the thermal capacitor (2).

Step 2 - Use the “T” end of an intercooler (or a flathead screwdriver) to install

the thermostat discs (1) and the thermal capacitor (2) into the heat

exchanger (4), and screw into place without overtightening.

Step 3 - Insert the extraction chamber (3) into the heat exchanger (4), and

screw into place. Then reverse thread the WPA (5) onto the chamber.

Step 4 - Snap the handle (6) beneath the bottom fin of the extraction chamber (3).

Gently squeeze the tabs to adjust the fit, adjust position if desired.

Make sure the thermostat

discs are stacked correctly.

Torch Heating

The Hydro can be used with any sized torch ranging from a small single flame to

a Blazer Big Shot. Simply point your torch at the heat zone of your choice and

wait for the thermostat discs to engage. No spinning is necessary.

Play with your flame distance/size to achieve your desired results. When using a larger torch like a Blazer Big Shot, don’t go below the

middle indicator and stop heating at the first click. It is not uncommon for both discs to click at the same time when using a larger torch.

Convection

Tip: Looser Pack

For convection leaning vapor, we recommend

a medium to large sized torch and keep the

flame pointed at the top indicator on the heat

exchanger (4) until it clicks.

Hybrid

Tip: Medium Tightness Pack

For hybrid leaning vapor, keep the flame pointed

at the middle indicator on the heat exchanger (4).

Pull at the first click for low-temp or pull at the 2nd

click for a higher temp. Use any small to medium

sized flame to dial in your experience.

to get familiar with the device

Conduction

Tip: Tighter Pack

For conduction heavy vapor, the darkest AVB,

and the most sedative experience, keep the flame

pointed at the lowest indicator (4) until it clicks.

Use a small single-flame torch for this as too much

heat makes overcooking a likely outcome.

Induction Heating

The Hydro can be used with induction heaters as well. These recommendations

will get you started producing great vapor. You can experiment with different

settings to achieve your desired results.

Ispire Wand

Tip: Align the first fin of the extraction engine

with the red gasket/glass

There are two ways to run the Wand. You can set the

Wand to 550f-650f and remove when the screen times

out (disregarding clicks). This will result in a Golden Zone™

roast. Or you can set the wand temperature all the way

up (max) and then remove during the first click or the

second. This will result in a higher temperature, denser

vapor, and darker AVB.

YLL 3.0

Tip: Align the first fin of the extraction engine

with the black gasket/glass

Set your wattage to 100w (it will automatically adjust

wattage output based on the remaining charge/voltage

of the batteries). Set the timer to 60 seconds for a Golden

Zone™ roast. Insert for an additional 5-10 seconds for a

dark roast. You can play with the depth insert of the YLL

to dial in your vapor density and AVB (inserting more or

less of the heat exchanger) and adjusting the timer.

Based on the current charge/voltage of the batteries, the time requirements and power

output may vary.
