Temperature Management Devices
Your Puretec UV system is designed to run continuously to ensure optimal disinfection.
However during periods when no water is drawn through the system, the energy from the
disinfection process can cause the temperature of the water inside the chamber to rise. In
extreme situations elevated water temperature or the fluctuation in temperature can lower
the output of the UV lamp. In these cases, or if the elevated water temperature is a nuisance,
Puretec recommends one of the following forms of temperature management devices.
Cooling Fan
Designed for use on the Puretec HO systems, the fan runs continuously
to cool the water by forced convection. The long-life fan is powered
independently using a compact modular power adapter that operates
from 90-265V (47-63Hz). Order

.
Temperature Relief Valve (TRV)
On reaching a higher temperature, the TRV is designed to drain a small
amount of water to allow fresh, cooler water to enter the system. The
TRV works without power and comes complete with 10’ of drain line.

Expansion Modules
Puretec controllers incorporate an “Infinite Expandability Port” (IEP) which allows for expansion
to the UV sensor and all other modules. Each module (including the sensor) comes with both a
male and female connection. Connect any device to the controller and all subsequent devices
are then connected into the female end of last device added in a “daisy chain” configuration.
The following optional expansion modules are available for use on Puretec UV controllers.
Contact your authorised distributor for purchasing information.
Remote Alarm Connection Module
Allows for a connection to a remote device such as a buzzer, light,
alarm system, PLC, etc via a pair of contacts. In normal operation
the OK and COM contacts will be connected, and in a fault condition
(Low UV, Lamp fail, Power Fail), the Fault and COM contacts will be
connected. Maximum Contact Rating is 30V / 1A (use 16-22 AWG).
