Non HCFC
Insulated Panel
We use cyclopentane as form blowing agent to expand polyurethane foam.
Non HCFC Insulated Panel is designed to be cost effective solution and higher performance thanthat of HCFC insulated panel.
It can also yield substantial improvement in the environmental impact.
We are the first and only one manufacturer of Non-HCFC Panel in Thailand. (by our research)

Air-tight Enclosure

The silicon-based sealant used the joint sections of the pales ensures excellent air-tightness,strongly rigid, and highly resistant to vibration.

Maximum Floor
Space

The panels are astylar and therefore allow for free design and layout arrangement, providing
you with maximum space within the room. Windows, doors and plugs may be incorporated
easily without decreasing the cleanroom performance.

Astylar Panels Allow
for Flexibility

The double-metal sandwich panels are highly rigid and have strong resistance against
erosion. As they are highly durable, they can be constructed independently, allowing forflexible construction design and layout.

CLEAN ROOM High Reputation in Chemical and Bio Technology. Design and Construct to meet your needs.
Cleanroom construction should allow for flexibility and freedom in designing the production line, but
at the same time it is necessary to take into account the cleanness of the environment. In addition,
maintenance and operation should be made smooth and easy.
Nikkei Panel System’s Cleanroom can offer you all of these qualities, and provide you with Cleanrooms
that are easy-to-manage from beginning to end.

Design of Panel Installation

Conditions that require attachment of strengthening furring strips(guideline)
In a case where a (indoor) wall panel receives no wind pressure, it
must be reinforced with furring strips if it exhibits a heat deformationlevel and a height that exceeds certain levels. The criteria for furring
strip attachment are shown in the table below, which are based on
the assumption that the panel is subject to no defrosting pressure orsuspended load.

Upper part : The furring strips must be
secured to the wall panel.
Lower part : The furring strips need
only to be attached which need not be
secured to the wall panel (back furring
strips)•The criteria shown in the table above should be used only as a guideline because they do not strictly take
into account the fact that different types of panels exhibit different heat deformation levels. In the designphase, a structural calculation is required each time.
•The criteria assume that the following requirement are satisfied.
1. The panel is installed indoor (not subject to any loads such as wind pressure).
2. Even for an RH refrigerator, a necessary relief dumper must be determined by calculation and installed.
3. If a load collapse defined by the Warehousing Business Act and other regulations occurs, cargos areloaded in racks, for example, and therefore do not fall on the panel.
4. Panels that use aluminum as the surface material are excluded.
5. The panel bottoms are secured based on floor embedding or floor angles (floor base are excluded).
6. Special cases such as rapid/frozen spirals should be separately considered.
7. During Installation, additional care should be exercised to ensure safety by, for example, temporarily
fixing the panels.

Using rigid polyurethane foam as the core material, our panel products
are thin and lightweight with a high level of thermal Insulation

This condition corresponds to that for a case where a refrigerator is placednear a wall. The temperature difference represents the difference between the outside air temperature andthe temperature inside the refrigerator.
•All of the performance values are measurements at cloth joints (joints between the ceiling and wall andjoints between the floor and wall). Near the floor, it is nearly airless.

Remarks
The operating temperature values should be used only as references. The most cost-effective panel

deformations in the panel surface caused by a concentrated load or
the like. The chart shows how the limit load changes according to theload’s diameter.

If a refriger ator is used in a stuf f y, hot and humid place,condensation may form on a panel surface. To prevent condensationfrom forming, a refrigerator should be placed in an airy, cool
location.
The humidity is approximately 50 to 60% in a room equipped withan air conditioner, which may be as high as 80 to 95% in a kitchenor outside.
The dew-point humidity depends on the conditions of the site. It isgreatly influenced by the wind speed outside the refrigerator. The
higher the wind speed, the higher the dew-point humidity.

About condensation

Asperities on the Panel Surface
Asperities present on a panel surface may result from a phenomenon we call a void. Although the core material has
small gaps, this has almost no effect on the thermal insulation performance because it is delivered on the panel surface.
In addition, asperities do not adversely affect the panel strength.

What Is a Void?

Why Are Voids Generated?

A void is a small gap present in the core material inside
the panel.

The core material grows inside the panel and catches air
during the filling process, resulting in voids.

Void

If the surface looks swelled:(This occurs when the room temperature is low.)(This occurs when the room temperature is high.)

The air inside voids decreases in volume,
pulling down the surface material.

The air inside voids expands,
pushing up the surface material.

Our panel provides stable thermal insulation performance; however, in an environment where the temperature andhumidity outside the refrigerator are high, in a stuffy environment, or in an environment that is likely to be affected by
the outside air, the panel may be subject to condensation, a phenomenon that water droplets are formed on the panel
surface. To effectively prevent condensation, keep the site well ventilated and properly insulate the site.
In periods when humidity is high, such as rainy season and summertime in particular, condensation may occur. In a casewhere condensation must be prevented to avoid trouble, it is required to take the following measures in advance.
Air-intake fan

Insulator (e.g. Eps Beads)

Air-exhaust fan

The core material grows,
catching air.
ĺ Voids are formed.

Depending on the environment, a prefabricated refrigerator/freezer may experience
condensation.

* How the surface looks depends on how it is lighted or the angle at which it is seen.

•To prevent condensation at panel joints:
Equip the site with an air conditioner for proper ventilation.
•To prevent condensation near the existing wall:
Insert an insulator between the refrigerator and wall.
•To prevent condensation on downstairs ceilings for a
multilayer hierarchical structure:
Install a thicker insulator on the floor on which the freezer/
refrigerator is placed.
Spray urethane to the downstairs ceiling.

Caution When Walking
on the Ceiling

You can walk on the ceiling for checking. Sections where you often walk should be
separately cured. In addition, ensure that no concentrated load is applied. Do not use
the ceiling as a scaffold during construction.
Walk softly using the entire soles of feetwithout allowing the heels of the shoes
to hit the ceiling.

Cautions about
Live Loads

Only one worker can ride on the panel.
Pay attention to the weights of objects tobe placed on the ceiling.
