Factory established
Designed and manufactured in-house -- not a trading company.
The problem with single-brand supply
Your engineering team already knows the frustration.
Price locked in
Established European brands charge a premium that no longer reflects the component's actual cost -- and your margin absorbs the difference.
Lead times slip
Single-source dependency means every allocation delay upstream becomes a delay on your container build schedule.
No leverage
Without a qualified second source, there is no negotiating position -- and no backup if the primary supplier fails to deliver.
Product specification
Modular sealing systems, engineered for drop-in replacement.
Round (TSR) and square (TSC) sealing assemblies with step-core rubber modules that adapt to multiple cable diameters within a single module size.
| Model | Frame size | Cable range | Sealing pressure | Material |
|---|---|---|---|---|
| TSC-120/40 | 120 × 40 mm | ⌀ 4-22 mm | 0.01-0.4 MPa | EPDM, halogen-free |
| TSC-120/60 | 120 × 60 mm | ⌀ 4-34 mm | 0.01-0.4 MPa | EPDM, halogen-free |
| TSR-060 | ⌀ 60 mm | ⌀ 6-28 mm | 0.01-0.4 MPa | EPDM, halogen-free |
Full range and custom sizes available. Test reports supplied on request.

Switching supplier shouldn't mean reworking your enclosure.
Match your existing frame cut-out to the DEWIN equivalent -- same footprint, no redesign required.
| Your current frame | DEWIN equivalent | Frame cut-out | Est. savings |
|---|---|---|---|
| 120-frame, 8 modules | TSC-120/40 | 122 × 42 mm | 40-55% |
| 120-frame, 12 modules | TSC-120/60 | 122 × 62 mm | 45-60% |
| Round transit ⌀ 60 | TSR-060 | ⌀ 62 mm | 40-50% |

Built for your industry
Wherever cables cross a sealed boundary.
Energy storage
BESS containers
Sealed entries between battery and control compartments, rated against dust, water, and fire spread.
Data centre
Modular halls
Dense penetrations through prefabricated panels, re-openable for later capacity additions.
Switchgear
Control panels
Standard cut-outs, so an existing enclosure needs no modification to change supplier.
