ASPA-01M is intended for continuous automatic control of vapors of ammonia in air production and warehouse, machine (equipment rooms) and condenser offices of ammoniac refrigeration units and refrigerating freezers. Functionally the signaling device is developed and is made in full accordance with the "Rules of labor protection and safety of ammoniac refrigeration units" existing now in the Republic.
LLC Arseptkhimanalitika has the License RB granted by the Gospromnadzor of the Ministry of Emergency Situations. The signaling device of ASPA-01M is entered in the Register of measuring instruments of RB.
The principle of action of a gas analyzer is based on change of resistance of the semiconductor gas-sensitive touch sensor at impact of ammonia vapors on it. ASPA-01M is the stationary device of continuous action with two fixed operation thresholds. A way of giving of the controlled environment in sensors - convection. The signaling device consists of the control unit and the alarm system and portable sensors of ammonia connected to the block communication lines. The control unit and alarm systems has to be installed in the personnel on duty serving the refrigeration unit. Sensors of ammonia are installed in rooms in which leak of ammonia as a result of accidents or malfunctions is possible. At achievement of threshold concentration of ammonia the device turns on the sound and light alarm system on the control unit and the alarm system, and also a light signal on an entrance to the gas-polluted room and emergency ventilation, disconnects power supply of all refrigeration unit and includes an external object siren. For convenience when using of a signaling device the light and sound alarm system of malfunction of sensors of ammonia and communication lines are provided in its scheme digital indication of concentration of vapors of ammonia on each sensor, and also.
