HVAC and Air Conditioning

TEE offers a complete heater bank (electric duct heater) package for the HVAC industry.
Thermal Electric uses high quality materials in all units, including Stainless Steel finned heating elements to ensure long-lasting and efficient use. Some companies will supply electric duct heaters with a mild steel painted surface finish which continuously bakes or burns over a period of time, releasing fumes into the duct. These fumes are known to cause Sick Building Syndrome (SBS) which affects all individuals within the building and can result in unwanted illness and possible liability.
Sick Building Syndrome is often caused by a HVAC system that is re-circulating polluted air.
Our SBS white paper can explain this in more detail.

Thermal can design and manufacture one off EDH units or hundreds of units, for projects both large and small,

Finned Air Heater Banks

Air Heater Banks for Duct Applications

Electric duct heater

Complete air heater banks incorporating the choice of elements are designed and built to meet the requirements of individual air conditioning installations. Once we have been provided with full details of the job, the most economic arrangement of elements, banks, etc, will be selected to comply with requirements. Terminal boxes are custom made to suit your duct size. Heaters are wired in the number of steps required to a terminal block inside, therefore enabling your electrician to connect up power supply easily.

Job data required for finned or unfinned heater banks

Air Heater Banks for Package Units

Package unit heaters comprise of elements mounted in a steel frame with removable terminal cover for easy connection of power supply by electrician. Job data required as above. (Disregard item 2 and instead state the size or brand model of air conditioning unit requiring the heater.)

Individual air heater elements

Individual finned heater elements are also available from our wide range of standard units, or custom designed to suit your specific needs.

Controls for the air conditioning industry

Manual reset overload

In accordance with AS1668 Part 1, temperature controllers and air pressure switches are required to eliminate overheating and possible premature failure of duct heaters.

Over Temperature controllers:
An over temperature controller is a thermally operated switch, designed to provide protection when it's capillary tube is heated above a preset cut out temperature. This could be caused by an accidental cutting of the air flow. Over temperature controllers come in both manual and automatic reset. The units are fail safe, if capillary is ruptured, the contacts open automatically.
Standard 2-hole mounting
Standard capillary length of 600mm
Standard lead length of 300mm

Evapodry Condensate Tray

Evapodry condensate tray

Thermals Evapodry tray can solve the problem of unwanted condensate by evaporating it from underneath the split systems compressor. The tray simply slides under the compressor and is plugged in.

The probe senses condensate that has accumulated in the tray and energises the heating element. When the probe senses the liquid has evaporated, the heating element is turned off.
The standard tray size is 400 x 400 x 55mm deep. Or a tray can be designed to suit your needs.
The standard tray uses a 240V 1000W heating element.
This tray conforms to health and safety standards in accordance with Plumbing Industry Commission - Section 7 Part E.
