The DCV will operate your process ventilation by monitoring the air pressure of your system.
The ES-90 control box is an energy saving control unit designed to be used for controlling exhaust fans in vehicle exhaust systems, with or without a particle filtration system. Together with optional activation devices such as a pressure switch, wireless control, or micro switch, this energy saving controller makes a fully automatic system for the control of the vehicle exhaust fan. The controller can be set for both manual or automatic control of the fan. Depending on the configuration of a system, several options for switches and remote start functions are available. The two most common switches used, are the MSR-24/2 or BRC-MS micro switch mounted on an exhaust hosereel or balancer to start and stop the fan as the hose is pulled down for use or retracted for storage.
The ES-90 also includes an alarm output, which can be used for status output to an onsite control system (by others). A built-in delay off function will ensure that the fan continues to run for some time after the vehicle has been disconnected, this ensures all of the toxic gases in the duct system will be exhausted out of the ducting before the fan stops. The delay off time can easily be adjusted between 4 seconds and 240 seconds.
The SA-24 control box is an energy saving control unit designed to be used for controlling exhaust fans in vehicle exhaust systems, with or without a particle filtration system. Together with optional activation devices such as a pressure switch, wireless control, or micro switch, this energy saving controller makes a fully automatic system for the control of the vehicle exhaust fan. The controller only functions in an automatic mode. Depending on the configuration of a system, several options for switches and remote start functions are available. The two most common switches used, are the MSR-24/2 or BRC-MS micro switch mounted on an exhaust hose reel or balancer to start and stop the fan as the hose is pulled down for use or retracted for storage.
