NEMA Rated Enclosures for Watertight and Explosion Proof Environments

NEMA enclosures are commonly used for electronics for automation, process controls, drives and
PLC’s. The thermal management of these electronic enclosures has become very important in
protecting expensive components, as well as the awareness of the cost of cooling these
enclosures.

NEMA cabinets are used for protection from the harsh environments encountered in many
industries,both indoor and outdoors. Without some form of cooling or heat removal,problems occur
with sensitive electronics. Most electronics can handle temperatures between 40c and 50c, some
more. It’s always a good idea to check the manufacturer specifications regarding the heat load of
the device being used; this will help in making the correct thermal decision for your applications.

The following are the most popular choices in the marketplace with some general pricing
considerations and assumptions needed to make a good decision.

First, is to purchase a cabinet large enough that can use natural convection to remove the waste
heat through the cabinet. You might not have the real estate for this option. This could potentially
cost more money than cooling because of the cost of the metal cabinet.

Second, would be the fan and filter. This option is the most economical of all but is not preferred in
dirty environments. The extra maintenance needed to clean the electronics within the cabinet
defeats the cost savings and puts expensive electronics at risk.

Third, is the thermoelectric device. This solid state air conditioner provides cooling while using
one watt of power to remove one watt of heat. They are typically used in small cabinets and are not
very efficient.

Next are the air compressor coolers. They use plant air to create a “Cyclone” effect that cools the
inside of the cabinet. The cost of plant air should be considered and if the air used is clean. They
can produce an oil mist inside the cabinet.

The panel air conditioner is used more than any other method. When electronics first made their
way into the plant, air conditioners had to be used because the thermal thresholds of the
electronics required that the temperatures be below ambient conditions.

Now, however, the components are made to withstand more heat. Air conditioner units cost more
to install and maintain and use more energy than most other options. The use of thermostats is
common to regulate the operation of use in certain conditions.

Finally you have the heat exchangers or cabinet coolers. These devices are being used more and
more because of energy savings and low maintenance. Most heat exchangers are designed to be
sealed from dust in the air and some can protect against moisture and corrosion They are generally
easy to install and very reliable. They also can be controlled by a thermostat. Air to water heat
exchangers can be used for high ambient applications where water is available.

For all outdoor applications sun load should be a consideration and the Neptech team can help you
this calculation.
Generally it’s a good idea to consider a sunshield.

When you look at an application as an integrator or end user be mindful of the safety factors that
may or may not be included in the thermal specifications. They are sometimes not necessary and
can cost you energy and dollars.

Energy savings has always been a factor, but more and more a necessity with the high cost of oil
and commodities in today’s world. With some consideration and effort you can make the right
choice for your application and customers.

NEMA RATINGS

NEMA 1
NEMA 1 enclosures are typically used for protecting controls and terminations from objects and
personnel. This style of enclosure, while offering a latching door, does not have a gasketed sealing
surface. NEMA 1 enclosures are used in applications where sealing out dust, oil, and water is not
required. Motor start/stop
stations are often housed in NEMA 1 enclosures.

NEMA 3R
NEMA 3R enclosures are typically used in outdoor applications for wiring and junction boxes. This
style of enclosure provides protection against falling rain, sleet, snow, and external ice formation.
Indoors they protect against
dripping water. This style of enclosure does not have a gasketed sealing surface. Some models
have hasps for padlocking.

NEMA 3S
NEMA 3S enclosures are intended for outdoor use primarily to provide a degree of protection
against windblown dust, rain, sleet, and to provide for operation of external mechanisms when ice
laden.

NEMA 4
NEMA 4 enclosures are used in many applications where an occasional washdown occurs or
where machine tool cutter coolant is used. They also serve in applications where a pressurized
stream of water will be used. NEMA 4 enclosures are
gasketed and the door is clamped for maximum sealing. They have continuous hinges, mounting
feet, and padlock hasps.

NEMA 4X
NEMA 4X enclosures are made of stainless steel or plastic. NEMA 4X enclosures are used in
harsher environments than standard NEMA 4 units. Applications where corrosive materials and
caustic cleaners are used necessitate the use of a NEMA 4X enclosure. Applications include food,
such as meat/poultry processing facilities, where total washdown with disinfectants occur
repeatedly and petro-chemical facilities, including offshore petroleum sites. NEMA 4X is used when
protection from the worst environments is required.

NEMA 6P
NEMA 6P enclosures are intended for indoor or outdoor use primarily to provide a degree of
protection against the entry of water during prolonged submersion at a limited depth.

NEMA 12
NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil. NEMA 12
enclosures are most often used for indoor applications of automation control and electronic drives
systems. Some examples are packaging,
material handling, non-corrosive process control, and manufacturing applications. Gasketed doors
seal the enclosure's contents from airborne contaminants and non-pressurized water and oil.

NEMA 13
NEMA 13 enclosures are intended for indoor use primarily to provide a degree of protection against
dust, spraying of water, oil, and non-corrosive coolant.
