The Powrmatic NVx downflow 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 NVx downflow 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. A ten year sliding scale warranty as standard on the heat exchanger.
The NVx 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 Brahma safety gas control provides an exceptionally high level of operational safety. The NVx 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 louver sections on the front of the heater allow the discharged heat to be directed to the required location in the work place. Additional horizontal louvers can be added for even greater air control.
The duct mounted version of the NVx 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 NVx downflow 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 NVx unit heater can be interfaced to almost any control station including the Powrmatic Powrtrol, MC200, MC300 (forthcoming) and the Heatmiser IQ+ controllers.
Powrtrol stations provide basic time and temperature options whilst the MC200, MC300 and Heatmiser IQ+ provide the optional signals for hi/low operation and 0-10v modulating control when required. Control stations are not supplied as standard and require onsite installation.
The range of Powrmatic NVx heaters are type tested to meet the stringent requirements the Gas Directive and are CE approved.
