Product Description
The CD series is the Wolong group's international low-voltage explosion-proof motor for gas and dust atmospheres, built on a modular platform and carrying the group's ATB brand. It holds ATEX, IECEx and CQST certificates, with additional dust protection II 2D Ex tb IIIC T120 °C Db, and meets the current European, Chinese and Australian efficiency rules at IE3 or IE4.
It is the choice when a project is specified to ATEX or IECEx rather than to Chinese GB rules, for example on European or Australian sites, offshore and LNG projects, or OEM skids that ship worldwide. The design covers extreme climates down to -55 °C (special versions to -60 °C).

Design Features
- Modular design: one platform covers many mounting, cooling and protection variants
- Changing the mounting position does not affect the explosion protection, so one motor type can serve foot, flange and vertical installations
- Low noise: special fan design and a vibration-damped bearing system
- Options: integrated frequency inverter, built-in brake, water cooling, PTC thermistors for winding monitoring
- Customer-specific designs for extreme ambient temperatures and special duty
CD Series or WEX3?
Both are Wolong group low-voltage explosion-proof motors. The WEX3 is the cost-effective export series from Wolong Nanyang for most international projects. The CD series is the European-platform alternative for projects that need a modular ATEX / IECEx design, combined gas and dust protection, IE4 or very low ambient temperatures. Send us the data sheet of your project and we recommend the series that fits.
Applications
Pumps, fans, compressors, mixers and conveyors in oil and gas, petrochemical, chemical, pharmaceutical, grain and other plants with explosive gas or dust, especially where ATEX or IECEx certification is required.
Explosion Protection Explained
Dust protection by enclosure ("t") keeps combustible dust out of the motor (IP6X) and limits the surface temperature below the ignition temperature of the dust layer. Zone 21 needs EPL Db (Ex tb), Zone 22 EPL Dc (Ex tc); group IIIC covers conductive dust.
Common Questions
What power range does the CD cover?
The CD covers 0.12 - 800 kW.
How is the CD cooled?
Cooling method: IC411, IC416, IC410.
What is the degree of protection?
Standard protection is IP55, IP56, IP65.
Documents Supplied with the Motor
For each order we can provide the technical data sheet, outline drawing, routine test report and, for explosion-proof motors, a copy of the Ex certificate that matches the nameplate marking. Tell us in the inquiry which documents your project or your inspector requires, so they are prepared before shipment.

How to Order
For a fast, accurate quotation please send: rated power (kW), voltage and frequency, number of poles or speed, Ex marking or hazardous zone, mounting type, quantity and destination port. For a replacement, a photo of the old motor nameplate is the quickest way to match it.
Frequently Asked Questions
Do your explosion-proof motors have ATEX and IECEx certificates?
Yes. Wolong Nanyang explosion-proof motors, both low-voltage and high-voltage, are available with ATEX and IECEx certificates for Europe and international projects, and GOST for the Russian market. Tell us which certificate you need when you ask for a quote.
Can this motor replace my existing motor?
Yes. For new projects we quote and select the model to your requirements. For a replacement, please send a nameplate photo or outline drawing of the old motor, and we will match the shaft height, mounting and installation dimensions.
Can you supply replacements for Schorch, Brook Crompton or Morley motors?
Yes. Schorch, Brook Crompton and Morley belong to the Wolong Electric Group, and we can supply Wolong motors built to replace them, matched to your mounting dimensions.
Can you ship to my country, and what is the lead time?
Yes. We ship worldwide on CIF terms, or you can use your own forwarder. The usual production time is about 3 months, depending on the model and quantity.
What information do you need for a quotation?
Rated power (kW), voltage and frequency, number of poles or speed, Ex marking or hazardous zone, mounting type (e.g. B3, B35, V1), quantity and destination port. A nameplate photo of the old motor helps if it is a replacement.
