Temperature Management Devices
Your CHANDLER 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,
CHANDLER recommends one of the following forms of temperature management devices.
Cooling Fan
Designed for use on the CHANDLER-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 PN UV-FAN3.5 (only fits UV H systems).
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 with-
out power and comes complete with 10’ of drain line. Order PN UV-TRV-0.5 for
1/2” ports, PN UV-TRV-0.75 for 3/4” ports, PN UV-TRV-1 for 1” ports and PN
UV-TRV-1.5 for 1 1/2” ports.
Expansion Modules
UVD and UVDM 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 subse-
quent 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 UVD and UVDM UV control-
lers. Contact your authorized distributor for purchasing information.
REMOTE ALARM CONNECTION MODULE: Al-
lows 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 Rat-
ing is 1A-120V AC/DC (use 16-22 AWG). Order PN
UVMOD-RAM.
