Industrial Electric Fan Heaters – 6kW to 22.8kW heating power output

Industrial Fan Heater or electric heaters for heating warehouses etc with thermostat for temperature control from Flexiheat UK

Industrial Fan Heaters – The LEO EL are warm air electric fan heaters with axial fans, a metal casing and electric heating elements, which are designed to heat industrial applications or rooms such as: industrial halls, workshops, warehouses, shops, commercial pavilions, sports and entertainment halls etc. These industrial fan heaters are very flexible and can work in a horizontal position as ceiling units and in a vertical position as wall mounted fan units. All of these electric unit heaters are supplied by a 3 phase /400 volt supply, which enables them to have a power output of 22.8kW at the largest size. This factor ensures that you can heat really quite large commercial and industrial working environments, with the easy of installing these ceiling or wall mounted fan heaters, along with their low capital costs, make them an ideal solution for many industrial or commercial heating applications.

As opposed to portable electric heaters, which will require a power lead, and also the aggravation of moving the units when you need to get at the area where the heater is located, or you need that floor area for something else, these wall or ceiling mounted electric fan heaters, once easily installed are out of the way, making for a cleaner and safer working environment.

This means that perfectly suited to small industrial units, workshops, garages, consulting rooms, laboratories, florists, and shops and alike. All of these commercial / industrial electric space heaters can be thermostat (temperature) and time controlled, making them a great solution as frost protection heaters, in greenhouses or any other application where this is a necessary requirement.

Industrial Electric Fan Heater Applications

Total Heating Systems – Units can meet the total heating requirement in most industrial plants, commercial and recreational buildings, and in special purpose structures such as animal shelters. The features that make them the ideal selection for these types of buildings are a long heat throw, uniform heat delivery and low installation and maintenance costs. High up and out of the way, these electric heaters provide heat into work areas for clean, safe, economical heating comfort.

Supplemental Heating – are ideal for spot heating applications during short periods of occupancy in the area to be heated. In out of the way locations, remote from areas served by the building’s main heating systems, electric unit heaters can often eliminate the expense of extending gas, steam, or hot water lines.

Stand-by/Back-up Heating – Where fossil fuel supplies are interruptible or undependable, electric unit heaters are recommended as a stand-by or back up heating system to supply comfort heating to an entire building or any part of it.

The “LEO EL” electric heaters with fan – up to 22.8kw heat output, these require a 3 phase electric supply from Flexiheat UK

These industrial electric warm air fan heaters benefit from :

  • An axial fan – The totally enclosed, thermally protected, continuous-duty motor is mounted to the fan guard utilizing rubber vibration absorbing material. The lightweight aluminium propeller type fan is connected directly to the motor shaft and is statically balanced for peak performance and low sound levels.
  • Electric heaters with PTC resistant heaters for maximum heat transfer. Elements are resistant to thermal shock and vibration.
  • External casing made of lacquered steel sheet;
  • Protection grille to protect against accidental contact with the heaters industrial fan- the fan guard is attached to the fan heater casing and provides a rigid support for the motor and protection from the exposed fan
  • As standard a single-row heat distribution grid – Adjustable up and down, the blades provide control over the horizontal air delivery of the fan heater.

Electric Unit Heaters – The Range

This range of electric fan heaters is made up of two warm air units –

  1. The Leo EL – S  – Which is an 10.8 kW maximum heat output, having two heating power output settings of either – 6 kW or 10.8 kW heating power
  2. The Leo EL  -L  – Which is a 22.8 kW maximum heat output, having three heating power output settings of either – 8.8 kW , 16.3 kW or 22.8 kW heating power

The full technical details of these industrial electric units are listed below –

Thermostat temperature control of the warm air heater range

These industrial electric fan heaters have two options for temperature control and fan speed control – these are a basic thermostat with manual selected fan speed (please note this fan heater range can also be used in a ventilation – non heating mode too). This controller is designated the “TS”.

Please note when using the basic “TS” controller – you lose some fan speed output steps and heat output levels depending on the heater size.

Our we can supply a more sophisticated controller, that also can be connected to a building management system (BMS) and can control up to 31 electric fan heaters. It is a full control system on its own as such which will ramp up and down the heat settings and fan speeds to suit the temperature set point. It also has a frost protection mode.

Industrial Fan Heaters / Electric Unit Heaters – Accessories & Options 

At the client’s request these industrial electric unit heaters can be manufactured with casing and heaters made from stainless steel. This is an option often requested for area’s that have high humidity or aggressive environments

We also supply a full range of additional accessories, which allow you to mix a proportion of fresh air and recirculated air through the heaters, via an external wall.

The KM-EL mixing chamber is designed to work with our Leo fan heaters. It enables the delivery of fresh (outside) air into the room. Depending on the requirements, the air flow can be heated via the PTC electric heating element and then directed inside the building.

The chamber is equipped with three air intakes: two for recirculation air and one for fresh air. The amount the damper opens can be changed smoothly from 0% to 100%.
