Engineered for severe operational environments across Bulgaria—from high-voltage sub-stations in Sofia to heavy manufacturing hubs along the Danube.
Bulgaria has transformed into a strategic industrial and manufacturing nexus within Southeastern Europe. Supported by European Union structural development funds and the Green Deal framework, the nation is actively modernizing its energy infrastructure, expanding industrial production zones near Sofia, Plovdiv, Ruse, and Burgas, and enforcing strict energy efficiency codes for commercial and residential developments.
These developments present rigorous requirements for precise thermal diagnostic equipment:
The maintenance of high-voltage transmission lines (managed by ESO EAD) and continuous thermal surveillance of critical generation assets—such as the Kozloduy Nuclear Power Plant and the Maritsa Iztok thermal power complex—demand uncooled thermal imagers with high thermal sensitivity (NETD < 40mK) to prevent unintended line trips and equipment degradation.
In accordance with EU Directive 2010/31/EU on Energy Performance of Buildings and Bulgarian Ordinance No. 7, civil engineers and certified thermographers require compliant instruments (such as the DP-64D and DP-25DV series) to map thermal bridges, evaluate insulation retrofits, and detect air leakage paths accurately.
Automotive assembly, copper refining (notably in the Srednogorie region), and heavy mechanical processing plants necessitate high-temperature thermography systems capable of continuous operation up to 550°C and specialized extended ranges up to 1200°C for foundry and kiln diagnostics.
The global thermography market is experiencing a shift driven by sensor miniaturization, edge computing, and multi-spectral sensor integration. Dianyang Technology stays at the forefront of this evolution through rigorous R&D and advanced manufacturing architectures.
Transitioning from 17μm to 12μm pixel pitch uncooled Vanadium Oxide (VOx) microbolometers has allowed for lighter optics and reduced device dimensions without compromising spatial resolution. This spatial resolution density ensures field technicians can resolve minute components at greater, safer standoff distances.
Modern infrared equipment goes beyond standard qualitative imaging. Real-time temperature measurement across every pixel (radiometric data stream) combined with visual image fusion (MSX/Dual-Vision) provides instant diagnostic clarity, automatically highlighting hot spots and cold anomalies directly on the field unit screen.
Dianyang's thermal cameras and core imaging modules are tailored for direct integration into Bulgaria's key industrial activities, providing accurate diagnostic workflows.
Regular thermal inspection of 110kV to 400kV transformers, circuit breakers, and busbars across rural and urban Bulgarian transmission corridors to identify high-resistance connections prior to terminal failure.
With rapid growth in photovoltaic installations across Southern Bulgaria (Thracian Valley), portable imagers like the H2F6B and DP-25DV allow maintenance crews to pinpoint defective cell strings, bypass diode failures, and micro-cracks rapidly.
Municipal steam and hot-water distribution networks in Sofia, Plovdiv, and Varna require subterranean pipe defect mapping. Portable high-resolution imagers detect underground thermal leaks efficiently through surface thermal gradients.
Select the optimal resolution, lens parameters, and operational temperature ranges suited for your specific Bulgarian inspection projects.

This strategic affiliation gives Dianyang unique access to VHD’s advanced R&D platforms, high-precision manufacturing systems, and rigorous quality management practices—enabling us to deliver thermal imaging products of higher reliability and consistency than typical ODMs.
We specialize in ODM/OEM services for infrared thermal imaging solutions, including handheld thermal imagers, smartphone-connected thermal cameras, thermal analyzers, and thermal imaging telescopes. Our products serve global customers in power inspection, building diagnostics, firefighting, industrial maintenance, and outdoor applications.
Our dedicated engineering team applies Design for Manufacturing (DFM), Design for Testability (DFT), thermal simulation, and EMC pre-compliance analysis to optimize performance and accelerate development. We also support clients in obtaining key certifications such as CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE.
For utility-scale power electrical substation audits (such as those for 110kV+ lines), we recommend at least 384×288 or 640×512 resolution (e.g., the DP-64D series). The higher detector pixel density ensures accurate temperature measurement on small targets like high-voltage clamp connections from a safe working distance.
