Reznor Europak 2000 units are fully
automatic gas fired heaters designed for larger
industrial and commercial applications, particularly
where combined heating and ventilation is required. At the heart of each heater is the perfectly co-ordinated combination of heat exchanger and burner, developed and patented by Reznor, that has set the standard for efficiency, reliability and operational life. Thermal efficiencies of up to 91% based on net calorific value. Units are simple to install, and are supplied complete and mounted on a base frame. An integral fan assisted flue exhausts the products of combustion and at the same time induces a precise amount of combustion air. External weatherproof units have a factory fitted flue outlet and combustion air inlet and require only connection to gas and electrical supplies. Internal units need connection to a suitable flue system. A comprehensive range of options allows the heaters to be tailor made to suit a wide variety of applications.
Europak units provide higher capacity heat outputs and airflows for larger applications. The units comprise modular components assembled onto a frame suitable for base mounting or suspension. They are delivered ready to install and require only connection to a gas and electrical supply and in the case of indoor units, a suitable flue system. Europak units are tailor made from separate elements to provide the required configuration of system functions to suit individual specifications. Appliances are compact, reliable, simple to install, energy efficient and require minimal maintenance. One or
more heating modules may be incorporated to give heat
outputs between 91 and 378kW. A wide range of drives and
motors provide airflow capacities between 8500 to 36000m3/h at external
pressures up to 400 Pascals. Europak PV units are for indoor installation and have a power vented combustion system with a fan assisted flue. They are extremely versatile and are used as room sealed balanced flue appliances, having the option of vertical roof or horizontal wall outlets. The flues may be extended by up to 9 metres between the heater and the balanced flue outlet. Europak RPV units are for outdoor installation and are supplied on a base frame and with a flue outlet terminal and combustion air inlet. Their low profile and neat flue termination makes the units ideal for applications where aesthetics are important. STANDARD FEATURES
OPTIONAL ITEMS
CABINETS All cabinets are manufactured from pre-painted galvanised steel based frame. Duct connections can be fitted as indicated on the drawings for all appliance air inlets and outlets. Damper requirements must be specified at the time of ordering stating rear (R) bottom (B) or top (T) as shown in the ‘Dimension Data’ drawings. FAN SECTION Fan sections consist of 2 or 4 forward curved double inlet centrifugal fans connected to a common drive system. An adjustable pulley is fitted to the motor to enable small changes in fan speed to be made to simplify on site balancing. Two speed motors are available for variable air supply or exhaust. Integral panel filters may be fitted within the fan cabinet for supply air sections fitted with motor sizes up to 3Kw, for units with larger fan motors a separate filter cabinet will be required. An optional air flow proving indicator may be fitted to supply and exhaust fan sections. GAS FIRED HEATING SECTION Indirect gas fired heating sections comprise one, two or four heat exchange modules as a single section, patented Thermocore venturi tube heat exchanger provides optimum efficiency and enhanced operational life. Standard units are fitted with heat exchangers manufactured from stainless steel (AISI 409). Where chlorinated vapours of certain other contaminants may be present 316 grade stainless steel heat exchangers must be used, consult Reznor for such applications. Units are tested and certified to current European standards and are CE marked. A multifunction gas control valve complete with dual shut off valves and a fully automatic ignition system provides full safety monitoring to each heater module. Fan operation may be controlled by an integral fan control thermostat, or a constant fan operation may be specified for ventilation applications. A limit thermostat monitors the operation of the heaters and shuts down the heater in the event of overheating or airflow failure. For additional safety all units are fitted with dual safety limit controls. FILTER SECTIONS Filter sections are supplied complete with in-built filter racks. Dirty filter indication may be fitted as an optional item. DISCHARGE/INTAKE SECTION Discharge and intake sections are fully insulated and supplied complete with duct spigot. MIXING BOX Dampers may be fitted to various sections as shown in the drawings or, where the unit configuration requires, a separate mixing box section may be added. Twin dampers i.e. Top and Rear or Bottom and Rear may be operated from a single damper actuator and linkage. Where dampers are located Top and Bottom then two damper actuators are required. Dampers may be manually controlled or fitted with two position or modulating damper motors. INSTALLATION Installation must be carried out by a CORGI registered installer in accordance with the manufacturers instructions. Europak PV units (indoor) require connection to a suitable room sealed balanced flue system. Flues may be taken vertically through the roof or horizontally through the wall, balanced flues provide both the flue outlet and combustion air inlet. Flues may be extended by up to 9 metres from the heater to the balanced flue outlet, 1.5 metres should be deducted for each 90º bend. Europak RPV (external) units are provided complete with an integral fan assisted flue outlet terminal and combustion air inlet grille. The flue outlet, air inlet and controls access are supplied as standard on the left hand side (LHS) (viewed in direction of airflow) for opposite handed units specify "RHS Controls". A gas isolation valve must be fitted adjacent to each unit. An electrical isolator is also required but the electrical supply to the units should not be switched off except for maintenance.
