IP68 Sewer Inspection Robot – What Does Waterproof Really Mean for Pipeline CCTV Malaysia
IP68 Sewer Inspection Robot – What Does Waterproof Really Mean for Pipeline CCTV Malaysia
Water resistance is one of the first specifications customers look for when choosing a sewer inspection robot.
That makes sense. Sewer, stormwater and underground drainage inspection can involve water, mud, moisture and wet pipe surfaces.
The WR030 manufacturer specifies the crawler protection level as:
IP68
However, there is an important detail that should not be overlooked:
IP68 applies to the crawler—not automatically to every component in the complete inspection system.
The WR030 manufacturer's safety instructions specifically state that the power supply box is not waterproof and must be kept dry.
Understanding this distinction is essential for safe and professional pipeline CCTV operation.
What Does IP68 Mean for the WR030?
For the WR030, IP68 is the protection level documented by the manufacturer for the crawler.
This is highly relevant because the robot is designed to operate inside pipelines where wet conditions may be encountered.
But MTM Precision should avoid expanding the manufacturer's statement into unsupported claims such as:
“Unlimited underwater operation”
or
“Waterproof at any depth.”
The supplied WR030 manual does not state a specific certified immersion depth or duration associated with its IP68 specification.
Therefore, the technically correct wording is:
WR030 Crawler Protection Level: IP68
—not an invented water-depth specification.
IP68 Does Not Mean the Complete System Can Go Underwater
A professional crawler system consists of several components.
For WR030TR, these include the crawler, cable system, cable reel/frame, control equipment and power-related components.
The manufacturer explicitly warns:
The power supply box is NOT waterproof.
This means operators should not look at the crawler's IP68 rating and assume:
“Everything can get wet.”
That would be incorrect.
Crawler vs Power Supply Box
The easiest way to explain this to customers is:
ComponentWater Protection Information AvailableWR030 CrawlerIP68 documentedPower Supply BoxNot waterproof – keep dryOther System ComponentsFollow manufacturer handling requirements; do not assume IP68
This distinction is particularly important when operating near:
Manholes
Open Drains
Wet Ground
Stormwater Systems
Sewer Access Points
The crawler goes into the inspection environment.
The non-waterproof power equipment should remain protected.
Keep the Power Supply Area Dry
The manufacturer's safety precautions specifically instruct the operator to:
Keep the power supply box dry
and
Keep hands and the power plug dry during operation
This should become part of the standard site setup procedure.
Before lowering the crawler into a pipeline, identify a suitable dry location for the control and power equipment.
Do not wait until rain, splashing or site water becomes a problem.
IP68 Does Not Mean Explosion-Proof
This is another critical distinction for sewer and industrial customers.
Waterproof ≠Explosion-Proof
The supplied WR030 manual does not state:
ATEX Certification
IECEx Certification
or
Explosion-Proof / Ex-Rated Certification
Therefore, MTM Precision should never present the WR030's IP68 rating as evidence that it is suitable for a potentially explosive atmosphere.
These are completely different safety requirements.
Why This Matters in Sewer Inspection
Underground drainage and sewer environments can require site-specific safety assessment.
A crawler being waterproof does not automatically establish suitability for every environment it may physically enter.
For any location where a hazardous atmosphere may be possible, the contractor should determine the required site procedures and equipment certification before deployment.
The WR030 documentation supplied to MTM does not establish hazardous-area certification.
This is especially important for professional contractors quoting industrial or infrastructure jobs.
IP68 Does Not Mean Chemical-Proof
The WR030 manufacturer describes the crawler as having an all-metal corrosion-resistant body.
The cable is also described as having tensile, scratch and corrosion-resistant characteristics.
However, these statements should not be interpreted as universal resistance to every industrial chemical.
The supplied documentation does not provide a chemical compatibility chart for:
Acids
Alkalis
Solvents
Hydrocarbons
or other aggressive industrial substances.
For specialised industrial pipelines, chemical compatibility should be confirmed before use.
Can WR030 Be Used in Wet Pipes?
The crawler's documented IP68 protection level and non-skid tyre design are relevant to wet-pipeline inspection.
However, actual site suitability still depends on the operating conditions.
Before deployment, contractors should consider:
Water Condition
Pipe Clearance
Debris
Sediment
Crawler Traction
Flow Conditions
Site Safety Requirements
The IP rating should be one part of the assessment, not the entire assessment.
Wet Pipe Does Not Mean Flooded Pipe Is Automatically Acceptable
This is another area where careful wording matters.
The supplied manual documents IP68, but it does not provide a maximum operating water depth or detailed submerged-operation table.
Therefore, MTM should not automatically advertise:
“Suitable for continuous operation at X metres underwater”
unless the manufacturer provides that specification separately.
For a project involving significant water depth or unusual submerged conditions, confirm the requirement before quotation.
What About the Camera?
The front camera is integrated into the crawler system.
The manufacturer specifies:
2MP Camera
360° Continuous Horizontal Rotation
190° Lens Flip
The overall crawler protection level is documented as IP68.
The manufacturer also describes front and rear 2MP HD low-light cameras as part of the robot's design.
This allows the camera system to be used as part of the crawler's intended pipeline inspection environment, subject to the manufacturer's operating requirements.
Wet Conditions Also Affect Visibility
Waterproofing and image quality are different issues.
Even if the crawler is protected against water ingress according to its documented rating, CCTV visibility can still depend on actual pipe conditions.
For example, the inspection image may be affected when the camera's view is obstructed by:
Mud
Deposits
Dirty Water
Material on the Lens
This is why cleaning and inspection after each job are important.
Clean the Robot After Every Inspection
The manufacturer's maintenance instructions recommend:
Cleaning after each use
and storing the equipment in a dry environment.
This is especially important after sewer and drainage work.
After retrieval:
Remove dirt and contamination
→ Clean equipment appropriately
→ Allow equipment to dry
→ Inspect cable and crawler
→ Store in suitable conditions
The manufacturer also recommends keeping the equipment away from volatile and corrosive substances.
Check Connections Before Entering the Pipe
The manufacturer's pre-use procedure recommends securely connecting the robot and winch/cable system before operation.
Before lowering the crawler into a wet environment, check:
Connections
Camera Operation
Front / Rear Camera Switching
Lighting
Crawler Movement
Cable Release / Retraction
Emergency Stop
It is much easier to find a connection problem before the crawler has travelled deep inside the pipeline.
Do Not Disconnect or Service While Powered
The manufacturer's safety instructions state that power should be disconnected during:
Installation
Cleaning
and
Repair
The manual also warns against unauthorised disassembly.
If an abnormal sound or smell occurs, the manufacturer's instructions say to cut the power.
These precautions are particularly important around wet working environments.
What If There Is No Image After Entering the Pipe?
The WR030 troubleshooting section provides several checks.
If the robot moves but there is no image, the manual recommends checking the relevant interface and camera-switching condition.
If the problem cannot be resolved using the documented checks:
Do not disassemble the unit yourself.
The manual recommends contacting after-sales support.
IP68 and the 120m Cable Configuration
The manufacturer's standard WR030 manual lists a 60m cable.
MTM Precision supplied its WR030TR customer with a:
120m Cable Configuration
For longer pipeline inspections, cable handling and condition become increasingly important.
The cable is described by the manufacturer as resistant to:
Tension
Scratching
Corrosion
However, the cable should still be inspected, cleaned and maintained after use.
IP68 + Automatic Cable Winding
WR030 uses an:
Automatic Wire Winding System
During crawler retrieval, the manufacturer instructs the operator to use the rear-view camera and coordinate cable winding speed with crawler reverse movement.
This becomes especially important after a long inspection in a wet or dirty pipeline.
Cable management should be controlled rather than rushed.
Five Common IP68 Misunderstandings
“IP68 means the whole system is waterproof.”
No. The manufacturer explicitly says the power supply box is not waterproof.
“IP68 means unlimited underwater depth.”
Not supported by the supplied manual.
“IP68 means explosion-proof.”
No. The supplied documentation does not state ATEX, IECEx or Ex certification.
“IP68 means chemical-proof.”
No universal chemical compatibility is documented.
“If it is IP68, maintenance is unnecessary.”
Incorrect. The manufacturer recommends cleaning after use and dry storage.
These distinctions are important when specifying professional inspection equipment.
What Should Contractors Ask Before Buying?
For wet pipeline inspection, ask:
What component carries the IP rating?
Is the power/control equipment waterproof?
Is an immersion depth and duration documented?
What pipe diameter is supported?
What operating environment is specified?
Does the site require hazardous-area certification?
Are chemicals present?
How should the equipment be cleaned after use?
This is much more useful than simply asking:
“Is it waterproof?”
WR030 Documented Operating Environment
In addition to its IP68 crawler rating, the manufacturer specifies:
Pipe Diameter: >300mm
Temperature: -10°C to +50°C
Relative Humidity: 0–95%, No Condensation
Atmospheric Pressure: 70–106kPa
These documented limits should be checked against the intended application.
