Description

The Kristall-3 (КРИСТАЛЛ-3) is a dual-component gas concentration monitoring system with integrated boiler-room dispatching, manufactured by OOO PKF Energosistemy (Saratov, Russia) — a specialist developer of gas hazard control systems with a product portfolio included in the Gazprom unified materials registry. The system simultaneously monitors natural gas (CH4) and carbon monoxide (CO) in controlled premises, and automatically shuts the gas supply via an electromagnetic cut-off valve (КЗЭГ) upon threshold exceedance.

The core assembly includes: SZTs-1 methane detector, SZTs-2 carbon monoxide detector, electromagnetic gas valve КЗЭГ, BUS-4 GSM dispatching and control unit with built-in GSM modem, VPK-1 remote monitoring panel, and a full set of pre-crimped connection cables. The BUS-4 GSM controller activates audible/visual alarms, triggers forced ventilation or other actuators per site-specific logic, and dispatches emergency alerts to up to 6 remote subscribers via SMS.

Logic programming is performed via a free SCADA application for PC or directly on the device. Power supply: 220 V AC.

Operating temperature: +1 to +50°C. Sensor technology: thermo-chemical and electro-catalytic principles, selected specifically to eliminate false triggering from non-target irritants.

The system is energy-dependent by design — valve closes on power loss.

Details & Equipment

System Components

Complete Kristall-3 Kit

The full Kristall-3 delivery set photographed together: VPK-1 remote monitoring panel (top left), SZTs-1 CH4 detector and SZTs-2 CO detector (top right), BUS-4 GSM control unit (bottom left), and КЗЭГ electromagnetic gas shut-off valve with connection cable (bottom right). All components are manufactured by OOO PKF Energosistemy, Saratov.

SZTs-1 Methane (CH4) Detector

The SZTs-1 gas concentration detector monitors natural gas (methane, CH4) using a thermo-chemical sensing element. Wall-mounted and bus-connected via RJ-type connector, it integrates into the Kristall-3 network without requiring additional wiring adapters.

SZTs-2 Carbon Monoxide (CO) Detector

The SZTs-2 detector monitors carbon monoxide (CO) using an electro-catalytic sensing element specifically selected to avoid false triggering from non-target gases. Its compact wall-mount housing matches the SZTs-1, simplifying paired installation in a single room.

КЗЭГ Electromagnetic Gas Shut-off Valve

The КЗЭГ series electromagnetic valves are available in threaded (муфтовое) and flanged variants for nominal pipe diameters DN 15 through DN 150. The valve body is brass or steel with nickel coating; it is energy-dependent — closing automatically on alarm signal or loss of power supply.

BUS-4 GSM Control Unit

The BUS-4 GSM is the central dispatching and control unit of the Kristall-3 system. It features an LCD display, RS-485/RS-232 interfaces, four relay outputs, 24 discrete inputs, DIN-rail mounting (160×100×70 mm), a built-in GSM modem for SMS alerting, and a power supply of 220 V ±10%, 50 Hz.

Connectivity & Control

BUS-4 GSM Network Integration Diagram

Manufacturer's diagram showing how BUS-4 GSM connects to higher-level SCADA software via RS-232/Modbus RTU, and optionally to PLC or Ethernet/TCP-IP infrastructure using a protocol converter. The GSM channel (antenna, top-left) delivers autonomous SMS and voice-call alerting to up to 6 subscribers when wired network is unavailable.

SCADA Software Interface & VPK-1 Wiring

The lower part of the page shows the four-wire wiring diagram for the VPK-1 remote monitoring panel, which mirrors all BUS-4 status indicators (gas alarm, valve closed, fire, intrusion) at a remote location without a separate power supply.

Model Designation Key

The manufacturer's official model code breakdown for the Kristall-3 line: the suffix encodes the valve nominal diameter (DN 15–150), maximum working pressure class (НД ≤0.005 MPa / СД 0.005–0.3 MPa / ВД >0.3 MPa), monitored gas type (CH4, CO, or combined), and optional GSM modem variant.

Features

🔥

Dual-gas detection: CH4 + CO

Simultaneously monitors natural gas (CH4) via the SZTs-1 sensor and carbon monoxide (CO) via the SZTs-2 sensor, providing two-hazard protection in a single integrated system.

📡

Built-in GSM dispatching (BUS-4 GSM)

The BUS-4 GSM control unit features an embedded GSM modem, enabling remote SMS alerts to up to 6 subscribers — eliminating the need for a separate telemetry device and simplifying installation.

🔒

Automatic electromagnetic gas shut-off (КЗЭГ)

The КЗЭГ electromagnetic valve — manufactured from steel or brass with nickel anti-corrosion coating — reliably closes the gas pipeline on alarm or power failure (energy-dependent, fail-safe design).

⚙️

Configurable actuator logic via SCADA

Relay output logic (forced ventilation, warning lights, sirens, third-party equipment) is fully user-programmable via free SCADA software for PC or directly on the BUS-4 device, with configuration save and one-click replication.

🔌

Unlimited scalable sensor network

The architecture supports an unlimited number of gas detectors in a single system with automated address assignment, using connector-based wiring that requires no special tools for installation.

🛡️

Certified sensor technology — no false alarms

All detectors use thermo-chemical and electro-catalytic sensing principles, specifically chosen to prevent false triggering from non-target substances; certification includes Газсерт, Интергазсерт, and type-approval certificates for Russia and Kazakhstan/Kyrgyzstan.

Buyer Benefits

All required cables with pre-crimped connectors are included in the kit — no additional tools or hardware needed for installation
Integrated transformer in the BUS-4 unit eliminates bulky external power supply blocks
Built-in GSM modem in the dispatching unit reduces total system cost versus a separate telemetry add-on
SCADA-saved configuration profiles allow identical replicated installations to be commissioned in one click
Included in the Gazprom unified materials and technical resources registry — accepted for use in Gazprom facilities

Applications

Unattended (automated) boiler rooms operating without on-site personnel Municipal and district heating boiler houses with operational staff Industrial production premises with piped natural gas Facilities requiring simultaneous CH4 and CO monitoring under a single control system Boiler rooms requiring remote dispatching and emergency notification to off-site personnel Agricultural complexes, poultry farms, and industrial sites with gas-fired equipment Projects where boiler-room automation logic must be customized per safety regulations of the specific facility Multi-zone installations requiring a scalable, addressable gas detection network
