Powrmatic LNVx Duo 140 kW Gas Fired Unit Heater
Bi-Directional Air Flow
The new Powrmatic LNVx Duo suspended range of unit heaters is ErP compliant and has undergone a total redesign from ground up including the striking charcoal grey colour scheme.
The Powrmatic LNVx Duo range features a reduced chassis size, allowing installation into the smallest of spaces without compromising output power or performance. The Powrmatic LNVx Duo shell has had a complete make over, now including additional structural folds to increase chassis strength and durability. Finished in a Charcoal Gray colour scheme using high quality polyester powder coat stove baked paint.
The LNVx Duo axial fans have newly developed anti-vibration mounts to further decrease noise and vibration compared to the older NVx range. Operating noise is heavily reduced.
The LNVx Duo heat exchanger design has further been improved allowing better heat transfer, improved airflow and is now suited to more applications than ever before. With each tube formed in a four pass profile of high quality aluminised steel and swaged ends preventing weld induced stress. Further factory options include both 409 and 316 graded stainless steel heat exchanger’s should the environment demand it.
The LNVx Duo electrical control panel has been moved from the bottom of the heater and folds out on an easy access chassis panel, making installation, service and maintenance easier than before. A unique plug and play configuration enables fast electronic replacement.
The Powrmatic LNVx Duo is the next generation unit heater, taking its predecessor the NVx through a total ground up redesign. Featuring Powrmatic’s unique patented NOx reduction system, users and installers can benefit from full compliance with the latest legislation on NOx levels and the entire range exceeds the requirements of the season efficiencies introduced in January 2018.
The Powrmatic LNVx Duo range remains cost efficient to purchase, install and operate in an increased range of applications.
The Powrmatic LNVx Duo range of gas fired unit heaters currently comprises of 12 different models, with heat outputs ranging from 15kW to 140kW. The unit heater is designed to be suspended directly in the work space that it will heat. Ducted versions are available with an up rated centrifugal fan option to overcome ducting resistance. The LNVx Duo can be supplied for use with Natural Gas (standard) or LPG (option). High low fire burner now supplied as standard or fully modulating gas valves available as a factory option.

The Powrmatic LNVx Duo gas fired unit heaters are built around minimal fuel usage, efficiency and reduced flue gas emissions. The entire range meets or exceeds current Building Regulations and additional control options are available. Hi/Low fire offers a two stage operation and a fully modulating 0-10v control option is also available, ideal for use with enhanced time and temperature control stations or links to building management systems.
The heater chassis contains separate modules, one to contain the heat exchanger tubes and a second insulated compartment holding the main operating components including the gas valve, safety thermostat, combustion fan and burner assembly. The cabinet is finished in a heavy duty stove baked epoxy powder paint.
The Powrmatic LNVx Duo heat exchanger is of exceptionally modern design. Each tube comprises of four full passes through the air stream and each is carefully mechanically bent with swaged and crimped ends to eliminate welding and thus associated issues during the manufacturing process. Custom heat exchangers can be produced in 409 and 316 grade stainless steel options for increased life in rough service conditions. Each tube is fitted with a Patented low NOx device, designed and developed by Powrmatic. A ten year sliding scale warranty as standard on the heat exchanger.
The LNVx Duo utilises in-shot burners, carefully designed and matched to fire directly into each heat exchanger tube. The specialist burner assembly uses a manifold to hold the gas injectors and are supplied from a single gas valve. Separate ignition and ionisation probes are utilised and a Pactrol safety gas control provides an exceptionally high level of operational safety. The LNVx heaters are supplied for use with natural gas (G20) as standard with an LPG Propane (G31) option available with a factory or site conversion.
Air movement is provided by a standard axial fan arrangement with larger models utilising multiple fans. Adjustable louvre sections on the front of the heater allow the discharged heat to be directed to the required location in the work place. Additional horizontal louvres can be added for even greater air control.
The duct mounted version of the LNVX Duo heater is supplied with a heavy duty centrifugal fan fitted directly to the heater. The front discharge grill is replaced with a heavy duty duct spigot to allow direct mounting to the air distribution duct.
The entire range of Powrmatic LNVx Duo heater is supplied with automatic ignition and flame safety monitoring, high limit overheat protection and separate control of heat and fan to allow a summer operation mode. The LNVx Duo unit heater can be interfaced to almost any control station including the Powrmatic MC200, MC300 (forthcoming) and the Heatmiser IQ+ controllers.
MC200, MC300 and Heatmiser IQ+ provide the optional signals for hi/low operation and 0-10v modulating control as required. Control stations are not supplied as standard and require on site installation.
The range of Powrmatic LNVx Duo heaters are type tested to meet the stringent requirements the Gas Directive and are CE approved.
