Saransk heating networks (a branch of Mordovian PJSC T Plus) carry out activities to transport thermal energy to the population, budgetary institutions and other consumers in the city of Saransk. As of November 2025, 756 km of heating networks and centralized hot water supply, 13 pumping stations, 104 central heating points are on the balance sheet.

The employees of KRUG as part of the commissioning works at the Central Process Center 2-8 S/Z and Central Process Center Banya Center performed the following works:

• controller equipment reprogramming,
• update the application software on the servers of the automated dispatch control system (ADMS) of the DPT,
• connection of new control cabinets of correcting pumps and control valves to the ADCS, which use frequency converters to control the temperature of the supplied network water and to ensure the temperature schedule of heating at positive outdoor air temperatures.

DTC control cabinets are equipped with industrial DevLink-C1000 controllers together with I/O modules of the DevLink-A10 series, which collect and primary processing of data with their further transmission via the GSM channel to the upper level of the system - to the Dispatching Center of Saransk heating networks. Control center workstations operate under the control of the Russian SCADA KRUG-2000.

The performance of these works allows the dispatching personnel of Saransk heating networks to monitor the quality of the supplied resource to consumers, monitor the state of the technological process and equipment in real time, and remotely control the operation of pumps and other equipment of the TSC.

The reconstruction of the TsTP was carried out by RMK LLC (Kstovo, Nizhny Novgorod Region). The company "KRUG" has carried out commissioning works in terms of DCS ADMS.

2021: Connection of all heat points of Saransk

All thermal points of Saransk are connected to a single digital control system. This was announced on March 9, 2021 by NPF Krug.

As of March 2021, all 103 TSCs are integrated in the automated dispatch control system SaranskTeploTrans Mordovian of the branch "."T Plus

The main goal of the project is to increase the economic efficiency of the heating networks of Saransk due to the transition to the "deserted technology" of the CTP management.

Constant operational control of heating network parameters, timely detection of heat losses and possible leaks ensures high-quality supply of heat and hot water to consumers.

SaranskTeploTrans is part of the Mordovian branch of T Plus PJSC. CTPs provide network water for heating and hot water to residential areas of Saransk. In total, in 2020, T Plus invested 380 million rubles in the reconstruction of heat supply and water supply networks in Saransk.

The automated dispatching control system (ADMS) of the SaranskTeploTrans TSC operates on the basis of the software and hardware complex of the KRUG-2000 CAS.

The WS of the system dispatcher under the control of the Russian SCADA KRUG-2000 collects the data of the main process parameters of heat supply from the control cabinets of the TSC and provides the issuance of remote control commands to them. Information from control cabinets is also transmitted to the existing telemetry system SaranskTeploTrans.

Information exchange between the DevLink-C1000 controllers installed on the DTC and the dispatcher AWS is carried out via a redundant GSM/GPRS communication channel using a GSM modem built into the controllers with support for 2 SIM cards.

The project was prepared within the framework of the Rubin-Automation consortium, which unites OJSC NPP Rubin (part of the Rostec structure) and LLC NPF KRUG. The consortium carried out a full range of work on the implementation of the system:

• design of control cabinets and upper level of the system
