Overview of the Fireflo industrial fan heater range

Overview: Fireflo Industrial fan heater

The Fireflo industrial fan heater range has been in the market for many years now and here at Puravent we have been supplying Fireflo heaters for over 10 years. Certainly in that time the industrial heaters in the range have evolved and developed, but there are some constants in that development, which are firstly that they are as tough as they always have been, and secondly that they have an easy availability of spares. You might say it that having an availability of spares is indicative of a heater that is unreliable, whereas, in fact all brands of industrial fan heater require spare elements from time to time, or the odd contactor, switch or overheat trip switch. The most frustrating thing for any owner of a big fan heater is when the heater is scrapped for lack of spare parts. It is a frustration that does not arise with a Fireflo industrial fan heater.

Including both 110v and 230v versions of the FF3, the Fire Flo range now includes 9 models. We have put together a brief video to outline the range.

Although the video gives a quick outline, there is far more information on the individual models and what they can do, the product listings on this website.

Fireflo FF125

Fireflo FF125 is more not so much a model but a capability statement. Want a fan heater to do 150kw? - no problem. Want the fan to deliver 500Pa or maybe even 5000Pa pressure? - no problem. You specify it and we can get it designed and built.

The Fire-flo FF125 is worth a special mention.

It is not included in the above table because it is more of a special than a standard product. Designed to meet your specific requirements and made to order the FF125 is not so much a defined product but a statement of what is possible. If you have a particular and demanding requirement for a big industrial fan heater then let us know about your requirement so we can propose some bespoke solutions.

Heat Load	Watts	BTU
Average The Room Is A Normal Residential Room, Office, Reception Area Or Similar, Where There Is Not Overly Crowded With People, Computer And Office Equipment.
Above Average There Are Factors That Contribute To Additional Heat Being Generated In The Room E.G. Strong Lighting, Overcrowding With People And Office Equipment, Conservatory Type Room, Or Flat Roofed Room.
High There Are Factors That Contribute To A High Heat Load In The Room. E.G. Commercial Cooking, Much Computer And Server Equipment, Switchgear, Temporary Building With Thin Walls And Flat Room, Plain Glass Conservatory.

Variable	Units	Notes/Guidance
System Airflow	M3/Hr	If you have it in cfm then multiply your cfm value by 1.7 to get m3/hr
Average Combined Pressure Drop Of Filters Of Higher Than F6 Efficiency	Pascals	F8 bag filters pressure drop - typical clean clean to dirty, 160 - 250 Pascals F9 compact filters pressure drop - typical clean to dirty, 160 - 350 Pascals H10 HEPA filter pressure drop - typical clean to dirty, 250 - 600 Pascals 9.8 Pascals = 1 mm wg, & 249 Pascals = 1 inch wg
Carbon Filters Pressure Drop	Pascals	For compact type carbons pressure drop between 100 - 150 Pa Bonded carbon panels typically 150 - 170 Pa Loose granular carbon panels typically 130 Pa
Annual Operational Hours	Hrs/Annum	8760 hours in a year If operating for 5 days a week, excluding public holidays, for 12 hrs/day = 3000 hrs
Cost Of Power	Pence Per Kwh	Huge variance in what different companies pay. heck your last bill to be sure, otherwise put in 10p
Fan Efficiency	(As Decimal Value, Eg 100%=1)	Would typically be around 60%, so if you don’t have specific information use 0.6
Fan Motor Efficiency	(As Decimal Value, Eg 100%=1)	Larger motors should be around 90%, so if you don’t have specific information use 0.9
