Overview
The BF-TD937 is a professional digital handheld for industrial sites where an ordinary radio is not allowed on the floor. It is supplied in an explosion-proof configuration with IIB/IIIC class protection and IP68 sealing, so it can be carried into process areas, tank farms and loading zones instead of being left at the gate.
Positioning and use
- Hazardous-area radio: built for sites where standard handsets cannot enter the process floor.
- Explosion-proof configuration: IIB/IIIC class protection and IP68 sealing.
- Where it works: process areas, tank farms and loading zones.
- Industrial construction: housing, sealing and interfaces suit gloved hands, drops and washdown.
Explosion protection and approval
- Permission first: on hazardous sites the first requirement is permission to operate, not a feature.
- Zone matching: the radio must match the classification of each hazardous-area zone.
- Configuration alignment: version, band and safety configuration must line up with the local licence.
- Pre-order check: we confirm the exact configuration against your zone classification and country.
- Documentation: technical documentation supports your safety department's internal approval.
Core functions
- ARC4 / AES256: advanced voice encryption protects traffic.
- Dual tactical covert mode: for inspections, observations or security posts where a visible radio would change the situation.
- GPS and BeiDou: multi-mode precise positioning gives dispatch a location for each radio.
- Large-site visibility: supervisors at large plants or off-site compounds can see where teams are rather than asking them.
- Multiple safety alerts: signal distress, a man-down style situation or an urgent need for assistance without composing a message.
Coverage and audio
- Same-frequency repeater (SFR): extends coverage without allocating a second frequency pair.
- Single-channel sites: suits a licence that provides one channel and no conventional repeater pair.
- Long-range coverage: for large plants and off-site compounds.
- Clear, loud audio: cuts through machinery noise in compressor halls and turbine buildings.
Durability and usability
- IP68: protects against dust and water immersion.
- On-board digital recording: keeps transmitted and received traffic for incident review or disputes.
- Bluetooth 5.0: supports a wireless earpiece or accessory where cables snag.
- TTS voice prompts: announce channel and status changes while the user keeps walking.
- 1.77-inch colour display: stays readable when the radio is checked at a glance.
- Safety layer: makes the radio part of the site's safety arrangements, not just a communication tool.
Ordering and OEM
- Destination country: tell us the market you are working to.
- Licence and band: confirm the band your licence covers.
- Zone classification: share the classification used at your site.
- Accessories: list the accessories your teams need.
- OEM: branding options are confirmed with the configuration.
- MOQ and lead time: confirmed at quotation.

Frequently asked questions
Click a question to see the answer
How do I confirm the right explosion-proof configuration for my site?
Hazardous areas are classified by zone, and the radio configuration has to match the classification used at your site as well as the band your licence covers. Send us the zone classification, the destination country and the accessories your teams carry, and we will confirm the matching configuration and the documentation your safety department needs.
Which frequency band version is available for my country?
Band allocation for business and industrial radio differs by market, so the same model is offered in more than one band version. We confirm the correct one against your licence before the order is placed.
Do we need a licence, and who applies for it?
Transmitting on licensed radio channels is the responsibility of the operating company in the destination country — normally handled by the importer or the site operator. We supply the technical documentation required for the application.
What does the same-frequency repeater (SFR) function do for coverage?
It extends coverage on a single frequency pair instead of requiring a separate repeater pair, which suits sites where the licence provides one channel and a conventional repeater cannot be deployed. Share your site layout and we will advise on how to plan coverage.
Can we order with our own branding and packaging?
OEM support is available, including logo and packaging. Send the artwork requirements and target quantity and our team will confirm what can be customised on this model.
What are the minimum order quantity and lead time?
Both depend on the configuration, band version, accessory list and quantity, so they are confirmed in the quotation rather than stated as a fixed number here.
