Precision sheet metal
Fibre laser cutting, bending and welding cells feeding the enclosure lines.
A seasoned team with more than twenty years in thermal design, backed by in-house automation, our own calculation software, and every test chamber the product range needs.

Refrigeration cycle modelling, CFD airflow balancing, acoustic and vibration work, and the electromechanical integration that turns all of it into a sealed box that survives shipping.
The Wujiang base runs precision sheet metal, aluminium and copper coil lines, and fixtures we design and build ourselves — which is why a custom bracket does not turn into a twelve-week tooling quote.



Fibre laser cutting, bending and welding cells feeding the enclosure lines.
Aluminium and copper coil processing with in-house expansion and brazing.
Automated evacuation, charging and helium leak detection on every unit.
Performance, electrical safety and functional checks before packing.
Complete product test and verification workflows, run in our own chambers rather than booked out to a third party — which keeps a design iteration down to days.




Also in the lab: HiPot and insulation resistance testing, IP ingress, vibration and transport simulation, acoustic measurement, and endurance running of complete units.

Heat-exchanger and air-conditioner selection tools built in-house and tuned against our own measured data, so a selection is traceable back to a test result rather than a supplier's generic curve.
DBS has built custom environmental control units for telecom operators, storage integrators and medical OEMs since 2019 — under a philosophy we put in writing because customers ask.
Laws, norms, regulations and standards of every market we ship into.
Every design tool and knowledge base we use is properly licensed.
Your drawings, your moulds, your intellectual property — protected.
Respect for quality technology and for fact, not marketing language.
Heat load, ambient range, enclosure, power, corrosion class, protocol.
Model proposal with performance data and a 3D outline drawing.
Prototype built on production tooling, tested in our own chambers.
Your qualification programme, our test reports and certification support.
Production release with end-of-line test records per unit.
The units we are proudest of started as a condition set somebody else had already declined to quote.
