The distinctive Thermolier Steam-fed Unit Heaters are fan driven, hot air heating system products, which utilise heat exchange technology to transfer heat from steam to the air, keeping costs at bay.
Front louvers and careful situation of the units gives exceptionally fast warm up and practical heat control in high roofed, large spaces. Requiring little or no maintenance, this system is tough and efficient.
5 Standard horizontal airflow models are available for order online. Both single phase or 3 phase power supply models available. If you require variation from the standard i.e. vertical down-flow models or flameproof motors please contact our sales team who will be happy to help.
Heat Outputs (kW) in drop-down below are based on 3 Bar of Steam pressure and entering air temperature of 20C.
Due to demand, lead times for the Thermolier Unit heater are currently 4-6 weeks. Please order at your earliest convenience.

In designing Industrial Heat Exchangers capable of operating at high extremes of temperature and in harsh environments particular attention has been paid to the areas most likely to fail through leakage. This is typically the point of joining the tubes to the header, particularly in the case of copper tube to steel header joints.
Central to the robustness of the high grade plate-fin coils is the unique steel encased tube header design which incorporates high grade thick walled copper tubes and BS EN1501-161-430 (EN10028) boilerplate and interference fit steel ferrules.
This unique design ensures integrity at high temperature and pressure and negates the requirement for traditional return bends which have inherent fragility and are prone to frost damage.
Commercial Industrial Heat has supplied heaters to oil platforms in the Baring Sea where they provide plant room frost protection in conditions reaching -30°c. We have also used this technique in heat exchangers at Sizewell B, Sellafield and other nuclear sites, as well shipping over 5,000 Thermolier units since the technique was developed.
Case study: Greencroft Bottling Plant
*The Tapered Ferrule Method is used for pressure jointing of copper pipes to steel headers in these industrial grade heat exchangers.
N.B. The products offered online are based on horizontal airflow/heat output with an option of either single or 3 phase electrical supply. If you require a variation on any aspect of the Thermolier, please get in touch with a member of our sales team who will be happy to help to ensure your requirements are fully met.

Heat Output Values based on a Steam Pressure of 3 Bar
Ensure no equipment is installed in a position that will obstruct the airflow from the unit. Even small bore pipe will cause turbulence in the air leaving the Unit and will prevent the unit delivering its full output into the occupied zone. The air intake should also be unobstructed.
Hangers must be fixed to both the unit the wall, truss or column. Ensure the hangers will allow the unit to move when the pipework expands.
The fanguard should be undamaged and securely fixed in the correct position.
Where the unit is fitted into ductwork a fan guard is not required. Check that the ductwork has provision for access to the motor and heater battery for annual inspection and maintenance. A short length of soft, i.e. canvas ducting should be fitted between the unit and ductwork to stop any vibration being transmitted into the ductwork.
It is recommended that the louvres are set as follows: Horizontal Units; louvres parallel, angled slightly downwards. Downflow units; when mounted at the upper recommended height each set of louvres should be parallel and angled slightly outwards. When mounted at the lower mounting height, the outer louvres should be angled outwards and the inner louvres vertical. This gives the maximum spread for the Downflow Unit. It also applies when used as a door heater.
