Sarajevo, located in the Sarajevo Valley surrounded by the Dinaric Alps (including Igman, Bjelašnica, and Trebević), presents a unique challenge for automotive and industrial thermal management engineering. Characterized by a humid continental climate (Köppen: Dfb), winters in Sarajevo frequently experience temperature drops reaching -15°C to -25°C. Furthermore, due to the city's basin topography, winter thermal inversion traps cold air and atmospheric particulates, creating significant air quality challenges.
To mitigate urban pollution, the Canton of Sarajevo under its Green Cities Action Plan (GCAP) is aggressively accelerating the transition toward zero-emission public transport (trolleybuses, electric buses) and commercial logistics fleets. However, sub-zero operations induce up to a 40% drop in Lithium-ion battery capacity due to elevated internal resistance and sluggish electrolyte conductivity. Without an optimized, high-voltage liquid heating system, vehicle range drops precipitously while cabin comfort is compromised.
Our Electric Heater Series incorporates Positive Temperature Coefficient (PTC) ceramic heating elements that reach operational maximum power output in under 30 seconds, accelerating windshield defrosting and interior warming without relying on waste engine heat.
Maintains high-voltage traction batteries (LFP and NCM) within the sweet spot of +20°C to +35°C during charging and discharge cycles, preserving battery health and maintaining fast-charging capabilities in Sarajevo's cold months.
Full adherence to UNECE Regulation No. 122 (Heating Systems) and Regulation No. 10 (EMC Compliance), allowing seamless integration into European vehicle fleets imported or retrofit across Bosnia & Herzegovina.
As an established automotive heating manufacturer, our high-voltage liquid heaters (ranging from 5kW to 35kW outputs) and PTC air heaters are built around CAN 2.0B / CAN-FD communication protocols. Global procurement managers requiring thermal modules for Sarajevo municipal retrofits demand four critical engineering guarantees:
Below is the standard technical matrix for our electric liquid heater series customized for Eastern European and Balkan fleet deployments:
| Parameter | HV Coolant Heater (Low Voltage) | HV Liquid Heater (Commercial) | HV High-Output Bus Heater |
|---|---|---|---|
| Rated Voltage Range | 12V / 24V / 48V DC | 300V - 600V DC | 600V - 850V DC (SiC Ready) |
| Heating Capacity Output | 2.0 kW - 7.0 kW | 10.0 kW - 20.0 kW | 24.0 kW - 35.0 kW |
| Target Applications | Passenger Cars, Cabin Defrost | Light Trucks, Sarajevo Vans | GRAS Sarajevo Transit Busses |
| Control Protocol | PWM / LIN Bus | CAN 2.0B / Auto-Diagnostics | CAN-FD with Dual-Loop MCU |
| Fluid Flow Rate | 12 - 25 L/min | 25 - 45 L/min | 50 - 90 L/min |
| Operating Temperature | -40°C to +105°C | -40°C to +105°C | -40°C to +125°C |
| Ingress Protection | IP67 / IP6k9k | IP67 / IP6k9k | IP67 / IP6k9k |

Navigating the transition toward 800V SiC architecture and localized Balkan logistics pathways.
As the automotive industry evolves from 400V to 800V electrical architectures, our thermal R&D engineering division is pioneering the integration of Silicon Carbide (SiC) switching electronics inside our liquid heaters. This architectural jump increases power efficiency to 99.2% while reducing control unit footprint by 35%.
Furthermore, for severe cold regions like Sarajevo, standalone PTC heaters are moving toward Hybrid Heat Pump + PTC Liquid Auxiliary Systems. Under ambient conditions down to -10°C, the energy-efficient heat pump handles primary cabin warming. When temperatures plunge lower in the Dinaric mountain passes, the high-voltage PTC heater seamlessly kicks in, eliminating thermal deficiency while protecting battery state of charge (SoC).
Exporting to Bosnia & Herzegovina requires deep familiarity with local customs protocols, EUR.1 movement certificates, and optimized intermodal transit.
