ABSTRACT:
A modular apparatus (10) for preparing dilute chemical compositions at the point of use, e.g., a customer's plant, is disclosed. The apparatus has upstream and downstream ends and includes an axial manifold (52) having a plurality inlet ports extending radially toward the center of the manifold, a valve (53) operatively connected to each inlet port, component supply conduits (18) operatively connected to the valve (53), at least one component supply vessel heater (23) proximate at least one liquid component supply container (12), a pump (56) in fluid communication with the manifold (52) to draw the liquid components into and through the manifold (52), a microprocessor controller (11) in communication with the valves (53) and (61) and pump (56), a flowmeter (60) in communication with the microprocessor (11) downstream of the manifold (52), a three-way valve (61) in fluid communication with the pump (55), and a container (70) which is in fluid communication with the three-way valve (61 ) in which the chemical composition is formed.
Also disclosed is a method for dispensing aqueous cleaning compositions at a point of use.
