Cooling Tower Panels

Indeeco Cooling Tower Control Panels offer a lower installation cost by reducing individually mounted temperature and liquid level control devices with one pre-engineered and assembled control package.


Product Inquiry

Standard Features

Solid-State Control
Outmoded bulb and capillary control has been replaced with new patented solid-state technology which combines temperature control with low water level protection in a single solid-state device.

NEMA 4X Enclosure
All controls are factory wired inside a rugged NEMA 4X enclosure designed for wet, outdoor use. Pre-engineered designs up to 96 amps are available with stock and built-to-order listings.

Lower Cost
Installation time and cost are reduced by replacing individually mounted temperature and liquid level control devices with one pre-engineered and assembled control package that requires only one probe to sense both water temperature and level.

Sensor Probe Specifications

Sensor Probe
INDEECO probe assembly incorporating both temperature and liquid level sensors. Probe is made out of 316 stainless steel to minimize corrosion. Probe can be installed vertically or horizontally.
Maximum Pressure Rating for Sensor Probe: 15 psi

12-foot outdoor rated cord with PVC hub connector for installation through tower basin wall. Options include different cord lengths or cord suitable for total immersion.

Cooling Tower Control Panel Specifications

Solid-State Control
Pre-set 45° F ON/OFF temperature control with 5° F switching differential and built-in low water cutoff. Circuit board LED’s provide visual indication of heater-on and liquid level status.

Ambient Temperature Range
-40° F to 150° F

Fail Safe
Output relay is de-energized if the input sensor is either open or short-circuited. This prevents heater burnout problems.

8″ x 10″ x 6″ for 40 amp size, 10″ x 12″ x 7″ for 50 amp size, 14″ x 16″ x 8″ for two circuits

NEMA 4X enclosure with pre-mounted electrical hubs for conduit connections

Single probe to sense both water temperature and water level. Sensor probe supplied with 12-foot outdoor rated cord pre-connected to control panel. Probe also supplied with PVC hub connector for attachments through cooling tower basin wall.
