Emerson 60HZ Manuel D’Utilisation

The Envirosource Module is an accessory to the Process Chiller, for use on systems that circulate 

water and/or glycol solutions that require an isolated loop from the emergency water source. With the 

heat exchanger providing fluid separation, the Envirosource automatically switches to the emergency 

water source on a high fluid temperature alarm. Additionally, the module automatically switches to 

standby pump operation (with interlock to shut down the Process Chiller pump) on a loss of flow 

alarm.
The Envirosource Module is available in 208/230/460V, single-phase and three-phase, 60 Hz configu-

rations. This module is a pre-piped and wired assembly that is encased in an almond colored, powder 

coated and baked cabinet. It consists of a copper brazed stainless steel heat exchanger, stainless steel 

pump, copper piping, RCM4 alarm monitor, adjustable time delay relays, high temperature thermo-

stat, cooling solenoid valve, check valve and flow switch. It also includes a manual ball valve and dou-

ble-check back-flow preventer on the city water line.
The integral RCM4 alarm monitor has a local display of normal operation, standby pump and standby 

cooling, “on” LED. Terminal strips are included for two optional alarms (customer supplied dry con-

tacts) and for common alarm output (dry contacts, NC/NO/COM). 

The Process Chiller is modified with a bypass line to permit water to flow around the chiller’s pump 

when the standby pump in the Envirosource Module is operating. This bypass line runs from the 

pump suction line to the pump discharge line and includes a ball valve and check valve (see 

Figures 1 and 2).
