From Our Satisfied Clients
ABLE Company has been essential to the sustained operation of our 6 high pressure boilers for many years. During our recent boiler replacement project, ABLE provided a new PLC based BMS/CCS for each boiler and also provided a seamless and well-organized integration from our existing control system to the new SCADA system used for plant monitoring. We have been counting on ABLE‘s support for years and plan to do so for many more, I highly recommend working with ABLE.
