The TOR-4 transformer oil drying unit is designed to remove water from the transformer, keeping it dry independently of the temperature and the state of water in the oil.
Ambient conditions for operation:
- ambient temperature 278 to 313К (+5 to + 40)°С;
- atmospheric pressure 84 to 106,7 kPa(630 to 800 mm. Hg.);
- elevation above sea level up to 2000 m;
- in open air under a canopy;
- indoors with ventilation.
Principle of operation
The TOR-4 online transformer dry-out system is equipped with adsorbers filled with zeolite sorbent, which absorbs water molecules as the treated liquid passes through it.
If necessary, the adsorbers can be easily dismantled and replaced with new ones, or the sorbent can be reactivated using the BRPS (BRZ) zeolite regeneration unit.
The system is connected to the transformer by rigid or flexible pipework. A pump pumps the oil from the transformer through the filter, then pumps it through the adsorbers (where moisture is removed from the oil) and the filter back to the transformer.
The operation of the system is monitored by a logic controller. The controller displays the moisture content of the oil before and after drying, the pressure on the filter, and the operation of the injection pump.
To protect the transformer against leakage, the oil level in the transformer is monitored. The required level is set and maintained in the controller. In case of oil leakage, automatic valves cut off oil flow from the transformer and the TOR-4 system stops.

- connection to a transformer of any type and age;
- the process of connection takes less than an hour;
- the sorbent captures water regardless of its temperature and form;
- the machine dries the oil without heating and does not require constant operator control;
- the machine can be installed temporarily or permanently;
- a robust housing that reliably protects the system;
- once saturated with water, the sorbent can be reactivated using the BRPS (BRZ) unit and reused for oil drying.
