At the heart of the heaters is the perfectly co-ordinated combination of heat exchanger and burner, developed and patented by Reznor, which has set the standard for efficiency, reliability and operational life.

The units are designed for conventionally flued applications and a flue socket is located on top of the units to accept single wall stainless steel flue systems.

X1000 models are available in capacities from 24 to 93kW.

All standard models are suitable for natural gas and are equipped with aluminised steel heat exchangers, thermoelectric pilot ignition and single phase motors. A comprehensive range of options allows the units to be tailor made to suit extensive application requirements. Options include stainless steel heat exchangers, automatic ignition systems, vertical louvres, 30, 60, 90 degree downturn nozzles. The heaters may also be specified for use on LPG.

For closer temperature control and reduced stratification, the units may be fitted with optional high/low or fully modulated burner control.

Reznor microprocessor energy management controls are available to complement the energy efficient heaters and optimise fuel economy.

EURO-X1000S

The standard axial fan versions are designed for freeblowing industrial and commercial applications. Units are equipped with high quality axial flow fans to provide good air distribution at low noise levels. Standard models are supplied with aluminised steel heat exchangers, thermo-electric pilot ignition and horizontal louvres.

EURO-X1000A

The high performance axial fan models are designed for freeblowing industrial and commercial applications where higher mounting heights are required. The units are fitted with an extended fan plenum chamber and a large diameter axial flow fan to provide substantially increased airflows. A high induction discharge head complete with both horizontal and vertical discharge louvres improves the air mixing and increases the air throw to ensure minimal stratification and uniform air distribution and temperatures within the building.

The units may be used in place of heaters fitted with lower airflow direct drive centrifugal fans to provide improved air distribution at lower noise levels.

The aesthetically pleasing design and improved air distribution ideally match the criteria for new low energy buildings.


EURO-X1000B

For use with ductwork, these units are fitted with belt driven centrifugal blowers and a duct outlet spigot. The large capacity forward curved centrifugal fan(s) are mounted on an angled plenum chamber to optimise the air distribution across the heat exchanger and a selection of motor and drive configurations enables the units to match a wide range of airflow and static pressure requirements.

The units are also ideal where freeblowing heaters are required at very high mounting heights. Use of the high capacity belt driven fans allows much higher airflows to be selected to ensure correct air distribution to the working zone. A range of outlets complements the choice of airflows. The high induction louvre, complete with horizontal and vertical louvres, may be selected, on downturn nozzles which can be used in multiples to provide 30, 60, 90 degree discharge.

Type D Downflow Plenum. For centrifugal fan units where a vertical downflow discharge is required, units may be fitted with a type D outlet. This downflow head is fitted with four individual sets of louvres which may be adjusted to give the precise air pattern required in two, three or four directions.


EURO-X1000E

Designed to meet a wide range of air handling applications, these units are supplied with forward curved centrifugal fans. A thermally insulated fan cabinet is available as an option. The fan cabinet may be fitted with a variety of filter options and also allows for the connection of recirculation ductwork.
Comprehensive drive and motor options allow a range of airflows and duties to be specified to suit duct system design up to 400Pa.

All models are fitted to a base frame which can be floor mounted or from which the units can be simply suspended using the four suspension points provided. Units are supplied as standard with an outlet spigot for connection to ductwork, but may also be used with the optional outlet heads for freeblowing applications.

A range of options, including high/low or modulating burner control, air flow proving or dirty filter pressure switches and constant fan facility, ensure optimum system design.

Units are also available for combined heating and ventilation applications where fresh air is required either in Winter or for Summer ventilation.

Where units are used to provide ventilation, stainless steel heat exchangers (AISI 409) are recommended. Dampers may be fitted to the back, top or bottom of the cabinet. Dampers fitted on the back and top, or back and bottom, may be linked to allow the cabinet to be used as a mixing box for fresh and recirculated air. Fully automatic operation may be achieved using two position, three position or fully modulating damper actuators, or alternatively, the dampers may be manually controlled.

Fully modulating burner control is particularly beneficial when winter ventilation is required and Reznor has developed a system to allow units to be used as conventional heaters which then switch over to provide tempered fresh air input once the space reaches design temperature. Where make-up or ventilation air is used a fast response ignition system should be specified.

SPECIFICATION
CABINETS
All components are manufactured from aluminised steel and exterior panels have a durable epoxy powder coat finish.

HEAT EXCHANGER
Patented Thermocore venturi tube heat exchanger with precisely matched burners provide optimum efficiency and enhanced operational life.
Standard heat exchangers are manufactured from special grade aluminised steel. For applications supplying fresh air ventilation, stainless steel heat exchangers (AISI 409) are recommended. Where chlorinated vapours or certain other contaminants may be present, AISI 316 stainless steel heat exchangers must be used. Consult Reznor for such special applications that may also require the use of separated combustion.

GAS AND SAFETY CONTROLS
Units are fully tested and approved to current European standards and are CE marked. For additional safety, Reznor units are equipped with dual limit thermostats.
Standard models are fitted with a thermoelectric safety control system. An optional fully automatic hot surface ignition system is also available.

AIR HANDLING
Axial fan models are fitted with direct drive axial flow fans and single phase 230V motors. Centrifugal fan models are fitted with double inlet forward curved centrifugal blowers and a belt drive with an adjustable motor pulley, to allow small on-site adjustments to be made. Motors may be single or three phase depending on the duty requirements up to 400Pa resistance.

INSTALLATION
Units must be installed by competent CORGI registered installers in accordance with the installation instructions. An adequate supply of combustion air must be provided as per the relevant section of the standards BS5440 & BS6230.
