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.


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

  • Cord: 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.

  • 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.

  • Nameplate showing maximum KW and amp ratings at system volts/phase.

  • System Wiring Diagram.

  • Installation and Operating Instructions.

  • Rated for maximum of 40 amps or 50 amps with disconnect switch when specified.

  • Suitable for multiple heaters per basin (maximum of 2 on 40 amp panel).

  • Disconnect switch with door interlock and operator handle, which can be padlocked in the "OFF" position.

  • Dimensions: 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
  • Control panels rated greater than 50 amps are supplied with two circuits and offered either with built-in fusing or a circuit breaker for each circuit.
