OUH OIL FIRED UNIT HEATERS

Indirect oil fired suspended warm air heaters with a stainless steel heat exchanger as standard and a downwards high/low firing pressure jet oil burner, available in 4 models with outputs ranging from 20 kW to 60 kW. Designed for use in factory or warehouse premises where oil firing is a requirement and floor space is at a premium.

Models Available

OUH F - Freeblowing Oil Unit Heater.
OUH C - Centrifugal Oil Unit Heater.
OUH D - Ducted Oil Unit Heater.

Features

Proven design and years of longevity make the OUH a leading recommendation for the HVAC installer, with simple maintenance access and ease of installation for buildings where only oil is available.
Meets the latest ErP requirements for reduced NOx and increased seasonal efficiency, utilising state of the art burners, air movement and control technology whilst maintaining the temperature rises required in cabinet heater installations.
Axial fan (OUH F) models are fitted with a single fan set and discharge warmed air directly into the heated space via adjustable horizontal louvres, with vertical louvres available as an option where lateral air discharge is required.
Centrifugal fan (OUH C) models benefit from a close coupled fan which discharges warmed air via a duct outlet spigot suitable for the onward connection of ductwork.

Specification

Type tested and CE approved. Heaters made available to the market from September 2018 onwards comply with the requirements of Directive 2009/125/EC - Lot 21 Tier 1.
Robust and proven heat exchanger manufactured as standard from 304 grade stainless steel and lifecycle tested to ensure long service life.
Fitted as standard with a pre-fitted and tested low NOx, high-low control "Gulliver" burner from market-leading burner manufacturer Riello.
