"Gerda" Products

The OSN-SNS bottom discharge arm is designed for safe and efficient unloading of petroleum, aggressive, and food liquids from railway tankers through the bottom nozzle. It uses full-bore stainless steel swivel joints approved for explosive areas by Rostekhnadzor. The unit supports over 9000 cycles without leaks and has a service life of at least 10 years. Supplied with a durable spring compensator for reliable operation.

KUIN cables are used in control, monitoring, and data transmission systems. They are distinguished by high reliability, resistance to external factors, and the ability to operate in extreme conditions.

Cables for airfields are designed to connect lighting equipment, including airfield lights and signs, to electrical networks. The cables have high resistance to mechanical stress, ultraviolet radiation, chemical agents, and extreme temperatures ranging from -60°C to +125°C. They comply with national standards, have a long service life, and can be used in harsh climatic conditions.

GERDA-TP cables are reliable telephone cables with polymer insulation, designed for operation in local communication networks. They ensure stable signal transmission under temperature fluctuations, humidity, and mechanical impact. The cables come in various designs, including armored, fire-resistant, and moisture-protected versions. GERDA-TP is used in primary communication networks, while its modifications, GERDA-ST and GERDA-TS, have additional features for special operating conditions. The service life of some models reaches up to 60 years.

Compact uninsulated conductors for power transmission lines are modern solutions that enhance the efficiency of overhead power lines. Due to their profiled wires (trapezoidal and Z-shaped), they offer several advantages: reduced corona losses, lower wind load, and minimized ice accumulation. The use of aluminum-zirconium alloys allows them to withstand high temperatures, ensuring reliable operation even under significant overloads. These conductors enable increased spacing between supports, making power transmission lines more cost-effective and durable.

The counterweight balances the drop pipe and equipment after hinge PST No. 3. Disk quantity depends on the load. Operator needs <4 kg of force.

GERDA-EL 224/225 elevated omnidirectional lights are designed for OMI and OVI lighting systems. Suitable for runway, taxiway, and threshold lighting.

The emergency level detector uses a piezo-based tuning fork to monitor liquid levels. Highly accurate, resistant to buildup, vibration and structural deformation.

Explosion-proof boxes GERDA-KSA and GERDA-KSN are designed for connecting cables in DC and AC circuits in areas with hazardous gas or dust environments.

Fire-resistant KUIN-SP cables are used in fire and security alarm systems, emergency warning and evacuation systems (SOUÉ), smoke ventilation, and automatic fire suppression systems. They comply with GOST R 53315-2009 and TR CU 012/2011 requirements and exhibit high fire resistance, maintaining operability for up to 180 minutes. These cables are designed for facilities with increased fire safety requirements, such as subways, airports, high-rise buildings, industrial enterprises, and explosive zones. Thanks to the use of mica-containing tapes and silicone rubber, they ensure reliability in extreme operating conditions.

The IP 330-GERDA flame fire detector detects flame sources based on infrared radiation across three spectral ranges, minimizing false alarms. It integrates with fire alarm systems via 4–20 mA, RS-485 (Modbus RTU), or 4-wire loops. Operating from –60 to +85 °C and protected from corrosion, it's certified for use in explosive zones (1Ex d ib IIC T4 Gb) and suits both indoor and outdoor installations.

The folding drop pipe is ideal for top unloading systems when using a telescopic pipe is not possible. Its folding design allows it to extend inside the tank under its own weight, thanks to PST swivel joints. To lift the pipe, the operator uses manual chains provided in the kit. The pipe is made entirely from stainless steel and tailored to the specific tank configuration.

The OSN-URM device is designed to heat high-viscosity oil products (fuel oil, bitumen, gasoil) before unloading from railway tanks. It uses a steam heat exchanger and an electric mixer to heat the entire volume efficiently. A drain tube removes condensate to prevent freezing and product contamination. The immersion depth can be adjusted for different tank types.

The OSN-MP gangway platform provides operators with safe access to tank trucks or railcars from loading racks. It can be fixed or movable, features spring balancers and a parking lock, and is operated manually by a rope. Suitable for mixed compositions with varying tank dimensions.

The SKZ-12-Ex-01.M is a stationary, multi-channel, continuous gas monitoring system designed for detecting hydrocarbon vapor concentration indoors and outdoors. It includes a 19" control panel (PK-12-H-01) and up to 12 explosion-proof infrared sensors (DZI-K-01 in plastic or DZI-K-02 in metal). Designed for real-time detection of oil and natural gas vapors, it is ideal for industrial safety in hazardous areas.

GERDA AGS LED signs use modern LED technology to provide durable, energy-efficient, and uniformly illuminated airfield signage. These signs comply with ICAO Annex 14, FAA AC 150/5345-46, and Russian standards AP-170 and FAP-381. Designed for easy installation and maintenance, they feature replaceable front panels, robust aluminum housings, and compatibility with existing transformer-based circuits. The system ensures continued visibility even if a segment fails.
