Photovoltaic Solar Power Systems
The photovoltaic power plants we build have both mains inverters and stand-alone inverters operating in island mode. They are in the range of panel power from 3kW to 1MW.
The electricity produced from power plants with network inverters can be for:
- Own needs.
- Own needs and sale of surplus.
- Sale of the entire amount of electricity produced.
The sites we have built are many and similar solutions are not only for companies focused on production, but also those who also want to reduce their electricity bills. Many farmers or landowners invest in power plants located on land that for one reason or another is not used.
The necessary steps for the construction of a power plant may be different for the different scale of the projects and the place of implementation, as well as there may be changes with the introduction of new legislation:
- Sketch - visa for designing a power plant (prepared by the municipality).
- ERC opinion (+ ESO opinion) (prepared by the ERC).
- Project:
- FEC project (prepared by designers).
- Transformer substation project - according to the opinion (prepared by designers).
- Project cable line MV - according to the opinion (+ plot plans, if in the land) (prepared by designers).
- Coordination of projects (ERP, ESO, municipality).
- Preliminary contract with ERP (prepared by ERP).
- Positive opinion from the fire safety authorities for the constructions I, II and III category (prepared by the fire brigade).
- EIA (prepared by the MoEW and RIEW).
- Assessment of the compliance of the project documentation with the basic requirements to the constructions (OSIP) (prepared by the construction supervision).
- Building permit (prepared by the municipality).
- Accession contract with ERP (prepared by ERP).
- Construction (investor).
- Commissioning (prepared by ERP, DNSK).
- Commissioning (prepared by ERP, DNSK).
- Request for inclusion in the relevant ERP.
- Production - the customer issues monthly invoices for the produced electricity to ERP on the basis of monthly protocols issued by ERP.
HVAC Automation
Specialized electrical panels for automation, instrumentation, and A.
Design and development of automation for air conditioning and ventilation systems. Port systems are implemented through automated panels or groups of panels that precisely control the processes of the HVAC equipment on a particular logic using sensors and detectors.
Design and development of systems for monitoring energy usage of HVAC installations and controlling them via the Internet and mobile phone.
The sensors that are used in HVAC automation are:
- Sensors for the flow of air/water
- Sensors for of air/water pressure
- Sensors differential pressure
- Temperature sensors
- Sensors for air quality and CO
- Sensors and motion detectors for the presence
Automatic control of heating, ventilation and air conditioning provides comfort to the occupants and increases energy efficiency.
With programable logical controllers (PLC), the user has control with high reliability and functional algorithm. The PLCs have appliances in industrial control for equipment and technologies, as well as in building automation, specialized lighting systems, heating, ventilation, and air-conditioning. These controllers are programmed using specialized software. The loaded programs in the PLC controller can be updated or rewrote at any time to meet the clients' or projects preferences.
The programs are written in specialized languages, mostly Ladderdiagram or FBD. It is also possible an already build automation systems to be monitored and parameterized remotely with the most commonly used protocols - DeviceNET, CAN, AS-interface, PROFIBUS DP, Ethernet, etc. There are models that provided connection and communication via RS- 232, USB, or even via GSM network.
There are different types of automation tools:
- ANN - Artificial Neural Network;
- DCS - Distributed control system;
- HMI - Human - Machine Interface;
- SCADA - Supervisory control and data acquisition;
- PLC - Programmable logic controller;
- PAC – Programmable automation controller;
- Control and measuring devices;
- Movement Control.
Building Management Systems BMS / BAS.
TEMPEX Ltd. builds building automation systems (BMS) using protocols such as Modbus, Profibus, BACnet, LonWorks, KNX.

Such systems are implemented mainly in hotels, hospitals and business centers.
Gas detection
Gas analyzers are measuring devices used for the analysis of gas mixtures to determine their qualitative and quantitative composition. They are used in inflammable and explosive areas and may be used to control the gases, contained in the air.
We design and build gas sensing systems to detect and measure the level of chosen gas. Signal and actuation mechanisms can be built for powering ventilation on and off, closing vent valves, etc.
Sensor types, according to implementation are divided into:
- Domestic
- Explosion-proof
Sensor types, according to the measured gas, are divided into:
- For combustible gases, volatile organic compounds, and hydrogen.
- For toxic gases and oxygen.
- For refrigerants - ammonia and freon
