Temperature Chamber with Explosion
Vent
This temperature chamber is suitable for drying and
heat-treatment of flammable synthetic resins or volatile
solvents. It is equipped with an explosion vent which
releases explosion and a safety door for security.
Door Equipped with a Single-Action
Lever
The door can be securely locked by an easy-to-use
single-action lever. Even if the operator accidentally
turns on the power when door is unlocked, the door
lock detection switch prevents heater fan from
starting. Further, in three minutes, the alarm buzzer
sounds to call for warning.
●
Release explosion safely
In case an explosion occurs inside the test chamber, as shown
in the below figures, insulation material is bent and blown
upward together with the aluminium plate to the metal screen
at the top of the chamber.
In this way the explosion is safely channeled and released
through the top metal screen. For SPH(H)-401, explosion is
released through the top metal screen by bending insulation
material on the rear wall.
WARNING
1) The following flammables or materials containing them
can be subjected to drying (heat treatment) with this
chamber. However, to avoid explosion, ventilate the
chamber well and use the chamber below the
explosive limit.
Inflammables:
●
Ignitable Substances
1. Ethyl ether, gasoline, acetaldehyde, propylene
oxide, carbon disulfide, carbon dioxide and other
substances with an ignition point of below
−
30
℃.
2. Normal hexane, ethylene oxide, acetone, benzene,
methyl ethyl ketone and other substances with an
ignition point above
−
30
℃
and below 0
℃
.
3. Methanol, ethanol, xylene, pentyl acetate
amylacetate and other substances with an ignition
point above 0
℃
and below
＋
30
℃
.
4. Kerosene, light oil, turpentine oil, isopentyl alcohol
(also called isoamyl alcohol), acetic acid and other
substances with an ignition point above
＋
30
℃
and
below
＋
65
℃
.
●
Combustible Gases
Hydrogen, acetylene, ethylene, methance, ethane,
propane, butane, and other combustible substances
that are in a gaseous state at a temperature of
＋
15
℃
and at a pressure of 1 atmosphere.
2) Temperature chamber with explosion vent is fitted with
a comprehensive range of devices to ensure safety.
In addition to the regular inspection, these must be
carefully inspected before reusing after an explosion.
3) This equipment is designed to prevent any damage to
people or equipment in the vicinity for explosion
pressures not exceeding 29.4kPa. If the explosion
pressure exceeds 9.8kPa, reuse of the equipment
itself may not be possible.
4) Please refer to the instruction manual before using the
chamber to ensure safe operation.
