5.4 Options
5.4.1 Option WCL (Closed Loop) Cooling Water System
The closed loop cooling water system is designed to separate the cooling water circuit
provided by the customer from that of the ozone generator. With this option, the
SMOevo
PLUS
system features a close loop cooling water system with circulation pump.
07.1.150
Centrifugal pump
The pump circulates the coolant between the heat
exchanger and the ozone generator in the primary
circuit. (Optionally with frequency converter).
07.1.140
Heat exchanger
The heat exchanger transfers the heat of the primary
circuit (generator circuit) to the coolant circuit provided
by the customer.
07.1.120
Pressure gauge
Pressure in the cooling circuit is approx. 1 bar (g) and
is displayed via the pressure gauge.
07.1.125
Pressure switch
In the case of too high pressure, a safety shut down of
the pump is initiated by the pressure switch (2.5
bar(g)).
07.1.115
Safety valve
The safety valve and the expansion tank are for
protection against thermal expansion.
The response pressure of the safety valve is 3.0
bar(g).
07.1.135
Expansion tank
07.1.130
Connection
assembly to
expansion tank
with shut-off
valve
For isolation with hose connection.
Allows checking the primary pressure of the tank and
replacing the tank without draining the system.
The shut-off valve must be open during normal
operation. The shut-off valve is sealed.
07.1.110
Air relief valve
The valves for de-aeration purposes must be closed
during normal operation.
