Download BrochureThe PSO range of heaters from Thermobile provide efficient and cost effective heating solutions for a wide variety of industrial, commercial and retail buildings. The range comprises 13 models with outputs ranging from 30 to 586 kW, available in upright or horizontal orientation for free blowing, ducted, plant room/enclosure or external applications.
Of frame and panel construction complete with integral heat shields and finished with a hard wearing epoxy powder coat stove baked paint.
Formed from a rolled and welded AISI430 stainless steel combustion chamber close coupled to a two-pass tubular heat exchanger. The heat exchanger benefits from a unique split rear header box allowing differential expansion of the two tube banks, whilst the aluminised heat exchanger tubes are hydraulically swaged into position to further reduce stress. Stainless steel heat exchanger options are available.
To ensure long life, reliability and optimum fuel efficiency, PSO heaters have been carefully matched to both Riello high/low and modulating burners as well as the Inverterjet range of pre-mix burners.
Air is moved via dynamically balanced centrifugal fan sets. Freeblowing heaters are equipped with heads providing rotational and lateral direction. Ducted heaters are provided with an outlet spigot for the onward connection of ductwork. A comprehensive range of return air spigots, dampers and filter accessories are available.
As standard, PSO heaters are supplied with approved safety controls including high limit protection, flame monitoring and sequenced ignition. For comfort, fuel efficiency and convenience, PSO heaters are provided with MC200 digital controls. To save installation time, controls for upright internal heaters are factory fitted and pre-wired, whilst controls for horizontal and external models are supplied in remote format (interconnecting wiring by others).
Gas fired units are certified for use on Natural Gas (G20) and LPG Propane (G31). Oil fired heaters can be specified at time of ordering for operation on Class D light distillate fuel oil (35 second gas oil), kerosene (28 second oil, model dependent) or bio fuel oil B10 (10% maximum).
PSO heaters are type tested and CE approved. Heaters placed on the market from 1st January 2018 meet the seasonal efficiency requirements of the Ecodesign regulation (EU) 2015/1188, Directive 2009/125/EC - Lot 21 Tier 1 (ErP).
