Standard Construction Features

Heating Elements
Industrial grade, 0.475" diameter steel sheath with brazed copper plated steel fins and epoxy sealed ends. Draw-thru airflow design pulls air across the heating elements to ensure cool element operation and even air distribution resulting in long element life.

Heating elements and motor are enclosed in a heavy gauge galvanized steel cabinet with a durable camel polyester powder coat finish.

Outlet Grille
Individually adjustable louvers are provided to direct airflow. A protective outlet fan guard is provided to prevent insertion of foreign objects.

Fan Motor
Permanently lubricated and thermally protected motor.

Built-in Controls
All units include an automatic reset thermal cutout that will de-energize the heater if an overtemperature condition occurs. A manual reset thermal cutout, in addition to an automatic reset thermal cutout, is standard on heaters 10 KW and above. A fan relay is provided to allow the elements to heat up before fan startup and purges the heater of residual heat after shutdown. A 24-volt transformer and disconnecting contactor are provided on most heaters. Single-phase heaters rated at 5 KW or less have line voltage controls; 24-volt control and contactor are available. Power fusing is standard on all heaters rated over 48 amps.

Universal horizontal or vertical discharge. Optional diffusers are available for vertical discharge. An Anemostat diffuser can be used to provide draft-free air movement at lower mounting heights. For higher mounting heights, radial diffuser with adjustable fins can be used to increase floor coverage or adjusted for a vertical down blast of air.

Learn how Thermal Products can assist you with your quick tank heating needs to your fully customized tank heating needs for all types of fluids.

In 1998 the Environmental Protection Agency (EPA) ruled that owners of Underground Storage Tanks must conform to standards that were established for secondary containment. Secondary containment tank is a tank assembly consisting of a primary tank and an integral outer secondary containment means capable of being monitored for leakage. EPA required all Underground Storage Tanks to be retrofitted to meet secondary containment requirements, removed or replaced by Above Ground Storage Tanks. Many State Agencies have indicated the use of Above Ground Storage Tanks is the best option. Above-ground Storage Tanks are usually installed outdoors which can lead to problems when the product viscosity is affected by colder temperatures. The solution is to add a heater to warm the product and maintain a free flowing viscosity.

Design Requirements:
An 8,000 gallon rectangular Above-ground Storage Tank filled with diesel fuel was installed at a major airport in the U.S. With a design outside winter temperature of ‐20ºF and 10 MPH winds a heater is required to maintain the fuel at 40ºF. Since no openings were allowed in the side of the tank the only access for the heater was through the top of the tank. Using the new INDEECO I‐HEAT heater selection program it was quickly determined that a 2 KW immersion heater would be required.

INDEECO selected an over‐the‐side flanged deep tank immersion heater with a remote industrial control panel. The heater used was a 3‐inch 150# carbon steel flange and 0.475 diameter steel elements rated at 6 watts per square inch. The 46‐inch long heating elements were mounted to a 76‐inch riser which positioned the elements in the lower half of the tank. The heater was furnished with both high limit and temperature control thermocouples.

One of INDEECO’s standard NEMA 4X industrial control panels equipped with a main power disconnect switch, controlling contactor, transformer, digital thermostat, Type J thermocouple controller, status pilot light and 150 watt enclosure heater was selected to control the heater.

INDEECO Advantages:
The customer was looking for a quick solution. INDEECO was able to offer a quick-ship standard industrial panel. The custom heater’s lead‐time was 5‐weeks and the panel was available in 2‐weeks.

An Advantage Engineering, Evaporative Cooling Tower Stand is used to elevate the outdoor mounted cooling tower to facilitate gravity return of water from the cooling tower to an indoor tank. Saving energy, by eliminating the need for a cooling tower pump and conduit runs and opening up critical ground space for other equipment needs.

Advantage Power Tower cooling tower cells from 45-135 ton capacity use a galvanized steel bolt together stand.

The galvanized steel, bolt together stand provides a rigid mounting and is easy to install. It requires no welding or post assembly painting and is designed to last for many years.

The stand is available in three (3) heights; 5 foot, 10 foot and 15 foot.

Power Tower cooling towers from 170-540 ton capacity use a welded and painted steel stand.

The Metal Particle Detector switch from AMOT can detect and alert equipment operations of the presence of metal particles in nonconductive fluid lubrication systems (lube oil, transmission fluid etc).

Typical applications

Developed for use in manual and automatic control systems:

  • Reciprocating equipment
    - gas engines
    - diesel engines
    - compressors

  • Rotating equipment
    - gas turbines
    - steam turbines
    - transmissions and gear boxes
    - pumps
    - compressors

At utility gas let down stations, the natural gas transmitted through the pipelines is reduced in pressure from the transmission pressure (up to 700 psi) down to a pressure range of 30-50 psi.  As the pressure is let down, the gas expands.  During the expansion of the gas it will cool, generally in the range of 10 F for each atmosphere of expansion.  As the gas cools, the water vapor in the gas stream will freeze if the temperature of the gas drops low enough.  The ice from the gas stream will cause severe problems in the valves and piping.  To avoid the potential problem of ice formation, the gas is heated prior to the pressure let down.  Typically the natural gas is heated from approximately 320 F to 850 F using a hot glycol solution or thermal oil at 1500 F.

Thermal Products recommends a high pressure API Heat Transfer Basco TEMA Type BEP or BEU shell & tube heat exchanger for natural gas heaters.  A type BEP is a straight through design allowing the heat exchanger to easily be installed in the pipeline.  With the high pressure gas flowing through the tubes, the BEP's floating tubesheet design protects the unit from the stresses of differential thermal expansion. 

The U-Tube configuration of the type BEU allows it to handle differential thermal expansion since the bent tubing is inherently free to expand.  Both the BEP and BEU designs avoid the use of packing on the tubeside thus minimizing the chance for a dangerous natural gas leak to the atmosphere.  A glycol solution or thermal oil from a Thermal Fluid Heater is circulated through the shellside of the heat exchanger, and returned to the boiler.  Natural gas heaters are sized using the lowest gas pressure case, since the maximum tube velocity is obtained from the lowest operating pressure.

A variety of materials can be used but generally the heat exchanger is constructed entirely of carbon steel.  This provides the required strength for the critical operating conditions while minimizing the cost of the heat exchanger.  A rupture disc is normally provided on the shellside to protect the heat exchanger in the unlikely event of a tube failure.  The rupture disc allows a safe escape of the high-pressure gas should a tube rupture allowing the gas to enter the shellside of the heat exchanger.
