The mandate
The company had compressors in two trailers outside the plant with inactive leak and temperature management systems that did not meet standards. Public health and the city were forcing the factory to bring its system up to standard with very tight deadlines.
The precise specifications were intended to protect workers and residents who reside near the plant in the event of ammonia leaks into the air. A system has been set up to contain them and to manage the compressor start-up instructions.
The challenge was to design a system while respecting the sophisticated specifications of the system.
The solution
The system must control the ambient temperature of the compressor room with fans and dampers in addition to managing a leak. The power supply had to be permanent and the system had to have a contingency plan in the event of equipment failure or breakdown.
This whole installation had to be linked to the fire system and to a central station that takes care of calling the necessary emergency services.
Automatisation DUBÉ created two systems, the first of which included:
-
2x Freestanding PLC cabinets and variable speed drives.The cabinet was in "Fail-Safe" design including UPS. A total of 210 I / O was installed in compressor rooms outside the plant.
The second system was installed in a room in the factory where there was a risk of ammonia leakage and which served as the central control of the entire system.
- A cabinet with UPS and I / O’s
- The interface between the other compressor rooms
The project was sold turnkey ready: complete management and installation.
From the design to the integration of the management system in the event of an ammonia leak, Automatisation DUBÉ managed the various trades (electrician, refrigeration contractor, instrumentation contractor) and took care of commissioning, training, designing a user manual, and supporting the system.
All the steps were completed respecting the very tight deadlines of the client and the city.
