In northern climates “shut-downs” can wreak havoc on your process when cooling tower basins freeze and upon “start-up”, cannot flow water to cool your process.

Thermal Products offers Indeeco’s pre-engineered, UL Listed/CSA Approved package for freeze protecting cooling tower basins.

Heaters are pre-set at the factory with a set point of 45F and will fit all tower manufactures below.

The Advantages of the Indeeco Cooling Tower Basin Heater package are as follows:

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
Most 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, two circuit panels use a NEMA 4 enclosure.

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.

Calorimeter Test Lab

Heat transfer manufacturer API Heat Transfer is aimed on advancing and testing the development of its air cooled, shell and tube, and plate products. They have installed a calorimetric air flow test lab which can simulate aitr flows to 30,000 scfm and air temperatures within engine compartments.


10TipsaHeaterThere are 10 major factors one should consider when deciding between open coil, finned tubular and tubular heater construction types for process heaters. Within these ten factors, the first four are key. If one heater type dominates these four considerations with its benefits, chances are it’s the right choice. If there’s no clear winner among these first four, the other six variables must be considered to determine the best design for the application.


coolingtowerA cooling tower primarily uses latent heat of vaporization (evaporation) to cool process water. Minor additional cooling is provided by the air because of its temperature increase. Cooling tower selection and performance is based on water flow rate, water inlet temperature, water outlet temperature and ambient wet bulb temperature.

circulationheaterElectric circulation heaters offer an efficient, economical means of heating water, oil, air or other liquids and gases. Careful planning and attention to heating requirements are essential to ensure that the heater you select will provide optimal performance for your application and offer years of trouble-free operation.
