Product Description:
Explosion-proof chiller is a kind of refrigeration equipment
specially designed for special environments such as flammable,
explosive, corrosive, and toxic. Its main feature is that it adopts
explosion-proof design in the refrigeration system, electrical
control system, and structural materials to ensure the safety and
stability of the production process.
The main applications of explosion-proof chillers include
petrochemical, pharmaceutical manufacturing, shipbuilding, mining,
military and other industries, as well as special environments such
as printing, paint, and dyes. In these industries, the presence of
special environments such as flammable, explosive, corrosive, and
toxic requires the use of explosion-proof chillers for
refrigeration to ensure the safety and stability of the production
process.
Explosion-proof chillers are designed with explosion-proof
structural materials, such as explosion-proof motors,
explosion-proof compressors, explosion-proof controllers, etc., to
prevent explosion accidents caused by sparks, static electricity
and other factors. At the same time, the explosion-proof chiller
also adopts a special refrigeration system and electrical control
system to ensure the safety and reliability of the equipment.

Working Principle:
The air-cooled explosion-proof chiller mainly realizes
refrigeration through a refrigeration system composed of a
compressor, a
condenser, an evaporator and a fan. It works as follows:
1.The compressor compresses the low-temperature and low-pressure
refrigerant gas into a high-temperature and high-pressure gas,
which is then sent to the condenser.
2.The refrigerant gas in the condenser is cooled and condensed into
a high-pressure liquid by exchanging heat with the outside air.
3.The high-pressure liquid is decompressed through the expansion
valve, becomes a low-temperature low-pressure liquid, and then
enters the evaporator.
4.The refrigerant liquid in the evaporator exchanges heat with the
outside air, thereby absorbing the heat in the air, and evaporating
the refrigerant liquid into a low-temperature and low-pressure gas.
5.The low-temperature and low-pressure gas enters the compressor to
start a new refrigeration cycle.
At the same time, the air-cooled explosion-proof chiller also
introduces air into the condenser and evaporator through the fan
for cooling and heat exchange. Due to the air cooling method, no
water source is required, and it is suitable for places where no
water source is available. At the same time, the air-cooled
explosion-proof chiller adopts an explosion-proof design, which can
operate safely in flammable and explosive places to ensure
production safety.

ensure safe operation in explosive hazardous environments:
1. Explosion-proof shell: The explosion-proof chiller adopts a special explosion-proof shell
design, which can effectively isolate the internal electrical and
mechanical components from the external environment, and prevent
explosive hazardous substances from entering the interior and
causing fire or explosion.
2. Explosion-proof electrical components: The electrical components of explosion-proof chillers are designed
and manufactured according to explosion-proof standards, such as
explosion-proof motors, explosion-proof controllers, etc., which
can operate safely in explosive environments and have the ability
to prevent explosions caused by electric sparks.
3. Explosion-proof cooling system: The cooling system of explosion-proof chillers adopts special
design and materials to prevent combustible substances from
entering the cooling circuit and avoid explosions. At the same
time, the cooling system also has good heat transfer and heat
dissipation performance, ensuring that the equipment maintains an
appropriate temperature during operation.
4. Overheating protection and explosion-proof monitoring: Explosion-proof chillers are equipped with overheating protection
devices and explosion-proof monitoring systems, which can monitor
the temperature and working status of the equipment in real time.
Once abnormal conditions are found, such as excessive temperature
or failure, corresponding protective measures will be automatically
taken , to avoid further danger.
5. Ground grounding and grounding protection: Explosion-proof chillers must be well grounded to ensure the
grounding reliability of the equipment and prevent static
electricity accumulation and electric shock hazards.
6. Strict certification and compliance: Explosion-proof chillers must comply with relevant explosion-proof
standards and regulatory requirements, and have passed
certifications from authoritative organizations, such as ATEX
certification, UL certification, etc., to ensure their safety
performance in explosive hazardous environments .
The comprehensive application of these safety features enables
explosion-proof chillers to operate safely in explosive
environments and effectively reduce the risk of fire and explosion.
