A short history of El Björn

El Björn is a Swedish company with a long track record. According to El Björn's own history:

• 1954: Karl-Henrik Enocson founded the business in Anderstorp, Sweden. It was then called Armaturartiklar AB and made small fixed distribution centres, fuse elements and busbars.
• 1960s and 1970s: the company started making multiple outlet sockets and heating fans as its own products.
• 1983: the business took the name El-Björn, after Björn Enocson, who had taken over the company.
• 1986: El Björn moved to Depågatan in Anderstorp, where it is still based.
• 2015: El Björn set up companies in Finland and the UK.
• 2019: El Björn and Satema came under the same owner, United Power.

Today, El Björn says its headquarters, production and warehouse "remain where it all began – in Anderstorp", that it is part of the United Power Group, and that its main markets are the Nordics and England. Its customers are mainly in construction, rental and manufacturing.

What makes El Björn heaters stand out

Built for rough site conditions

El Björn has been making fan heaters for decades. On its Power range page, the company says that "since the 1970s, El-Björn has set the standard for safe fan heaters", and that its fans are made of powder-coated galvanised sheet steel with a grille designed to increase throw length.

The TF18 EBC page on El Björn's UK site describes the heater as built from galvanised sheet steel with a corrosion-resistant powder coating, with roll wheels and locking brakes so it's easy to move around site.

Quality and safety are tested, not sampled

El Björn's UK "About us" page sets out three values: functionality, quality and safety. It says the functionality of every product is checked before delivery and that "random testing is not an option". It also says El Björn uses only recognised component suppliers, carries out the safety testing each market requires, and has its products officially classified for things like ingress protection.

On quality and environment, El Björn says it has held ISO 9001 certification since 1997 and that its whole business has been certified to ISO 14001 since 23 February 2006.

IP44 and overheat protection across the range

Every El Björn heater we list shows an IP44 protection rating on its product page, and models such as the TF3, KH9 and TF9EL list overheat protection.

360° air distribution

The TF range spreads heat in all directions rather than blowing it one way. The TF18, TF18 S, TF36 EBC and TF72 EBC all have 360° air distribution, and even the compact TF3 has four outlets. In a site cabin or an open-plan floor, that means less of a hot spot by the heater and a cold corner at the far end.

Dust filters and digital control

The TF18 has dual G4 dust filters, which matters on dusty sites. The EBC models add digital control. For example, the TF9 EBC has a digital display with temperature and humidity monitoring. El Björn says its TF EBC heaters work with El-Björn CONNECT, its online system for monitoring room temperature remotely.

The El Björn range at a glance

All figures below are from our product pages. Most models need a three-phase supply and will not run from a standard 110 V or 230 V socket.

Model	Heat output	Power supply	Best for
TF3	2.8 kW	110 V or 230 V	Commercial and site drying or heating
KH9	4.5–9 kW	3N-400V, 13 A	Retail and industrial areas
TF9EL	4.5 / 9 kW	Three-phase	Compact site and industrial heating
TF9 EBC	9 kW	Three-phase	Spaces where you want to monitor temperature and humidity
KH12	6–12 kW	3N-400V, 18 A	Commercial, industrial and construction spaces
KH18	9–18 kW	3N-400V, 25 A	Larger commercial, industrial and construction spaces
TF18 (EBS or EBC)	9–18 kW	3N~400V, 27 A	Even 360° heat with dust filtration
TF18 S	18 kW	Three-phase	Simple stop/start use with preset settings
TF36 EBC	18 / 36 kW	Three-phase	Large industrial and construction spaces
TF72 EBC	36 / 72 kW	Three-phase	Very large industrial spaces

Three-phase heaters need the right lead. We stock El Björn 16 A, 32 A and 63 A extension cables. Check the heater's rated current and plug against the cable and your site supply before you order, and ask us if you're unsure.

How to choose the right El Björn heater

1. Work out the heat you need. Use our free heating calculator. Enter the size of the space, the type of building and the temperature rise you want. For a full walk-through, see our guide How many kW do I need? A practical guide to sizing site heating and choosing the most practical solution.
2. Check your power. Most of the range needs a 400 V three-phase supply. If you only have 110 V site power or a 230 V socket, the TF3 is the model that fits.
3. Decide between one big unit and several smaller ones. Two or more smaller heaters can spread heat better in long or divided spaces. One large TF unit can be simpler in a big open area.
4. Choose your controls. Analogue models like the KH range and TF18 EBS are simple to set. EBC models give you digital control and, according to El Björn, CONNECT compatibility.
5. Check the warranty. Warranty terms differ by model, so check the product page. Several, including the TF3, KH9 and TF18, show a 5-year manufacturer warranty as stated by the supplier.

Heating is also about welfare. HSE lists portable heaters as one way to keep work areas warm enough while they're in use.
