Features
Internal Heating System
Internal heating system circulates
heat throughout the chamber, with
a max. temp. of 180˚F(82˚C).
Pressure Relief Valve
Lets out a quick release of air be-
fore the tank’s maximum
pressure is reached. (110 psi)
Temperature Control
Digital user control with
variable output for precision
molding and curing.
Pressure Gauge
Easy to read 0-150 psi or 0-10
Bar pressure gauge. The tank’s
maximum pressure is 110 psi.

5
Features
Fully insulated tank for increased
heat retention and energy efficiency.
Thermal Insulation

Safety & Maintenance
Unit will become warm to the touch
and possibly hot when in use.
 Unit MUST be securely mounted to a bench, heavy duty cart, or
other sturdy surface before using. The 3/8” fastening holes in base
units can be used to secure unit.
 No flammable materials(i.e. solvents) should be placed near or inside
the X-20 unit.
 The location of the X-20 unit should provide enough clearance for the
swinging lid to open.
 A suitable 15 AMP, 115 VAC circuit should be within 5’ of the X-20
unit.
Note: This device uses 440 WATTS at 120 VAC @ 60 HZ. Users in a foreign country
are responsible for procuring the proper converter that meet the standards and require-
ments for use.
 A sufficient clean, dry air supply should be available to pressurize the
unit.
 Use “DANGER DO NOT OPEN” tag on each machine while they
are under pressure.
 Clean debris from top of shelf and underneath on a daily basis.
 Check fittings and valves for pressure leaks on a weekly basis.
 Grease the tips and threads of 6 clamping bolts and check cover align-
ment on a monthly basis.(See Pg. 12)

Initial Startup Preparation
1. Remove the X-20 from the shipping crate by taking out the
screws from the box and unbolting the brackets from the
bottom.
2. Place the unit on a sturdy, level surface close to electrical and
air supply.
4. Loosen the swing clamps(6) and open the lid.
3. Secure the X-20 using the same bolts it was attached to the
crate with.
The Molding Chamber is now ready to use.

Using The X-20
2. Close the lid and securely tighten the swinging “C” clamps.
To prevent the seal from deforming, tighten the clamps in a
crisscross sequence as opposed to a clockwise or counter-
clockwise sequence. Be careful not to over-tighten.
WARNING: Exceeding 200 inch pounds may distort the
gasket and cause damage to the sealing surface.
4. Slowly open the ball valve until desired air pressure is reached.
70-80 PSI is recommended.
1. Place molds and parts on the shelf, making sure they are level.
3.Attach the air hose to the unit while in the “shut” position”.
5. When the desired pressure is reached, close the ball valve
and remove the air hose. We recommend 70-80 PSI for
most applications.
For heating instructions please see page 10.

9
Using The X-20
Caution! : Items may be hot when removed!
WARNING : DO NOT OPEN DOOR UNTIL PRESSURE HAS BEEN RELEASED!
6. When de-mold time is reached, slowly relieve pressure from
the tank by turning the valve back to the open position.
EAR PROTECTION RECOMMENDED!
8. Open the door and remove the cured items from the unit.
7. Once pressure has been fully relieved, loosen the swing
clamps using an adjustable wrench.
NOTICE: Operating the X-20 with both heat and pressure causes expansion and contraction
of sealing surfaces throughout the chamber. Under these conditions, it is normal for the tank
to lose some pressure over an extended time period. For typical resin curing applications, it is
only necessary to maintain pressure until the material has reached it’s gel state. In situations
where constant pressure must be maintained for the entire cure cycle, we recommend using a
pressure regulator and leaving the air hose attached to the chamber.

10
Using The Heating System
1. To turn on the heating system, push the red button on the right
of the unit.
2. To change the temperature, press the SP(Set Point) button twice.
3. Using the “up” and “down” arrow buttons, change to the desired
temperature(ºF) and press the SP button to enter the new value
into the controller.
The X-20’s heating system is digitally controlled and, unlike similar devices on the market,
heated from the inside of the chamber. The digital controller allows the user to easily set the
tank’s temperature while displaying a digital readout of the current temperature. The heater
automatically turns off once it reaches the set point and turns back on when it goes below by a
few degrees. The maximum operating temperature is 180˚F (82˚C).
4. To exit the set point function and check the current temperature,
press the “SP” and “Down Arrow” button at the same time.

Temperature Conversion Formulas & Chart

1.) Slightly loosen center 2.25” bolt and center cover so that it is
concentric with the outside diameter of the tank.
2.) Securely tighten the swinging “C” clamps in a crisscross pattern,
as you would tightening lug nuts on a tire, EXCEPT for the clamp
on the hinge arm. (Should remain slightly loosened)
3.) Tighten down the 15/16” vertical bolts that attach the hinge arm to
the side of the tank.
4.) Using a large flat jaw adjustable wrench, tighten down the center
bolt as securely as possible.
NOTICE: Due to repeated opening/closing, cover may have tendency to loosen over time
and cause misalignment. To re-align the cover, follow the steps below.
