Z.R.E. ... Infinite solutions ... Infrared heaters MODEL Z.91 (INFRARED) MODEL Z.92 (HEATLAMP) MODEL Z.93 (QUARTZ) Z.R.E. Ceramic infrared elements Technical features Model Z.91 infrared General features Ceramic infrared heating elements are efficient, robust heaters which provide long wave infrared radiation. Ceramic elements operate in the temperature of 300°C to 700°C (572°F - 1292°F) producing infrared wavelengths in the 2 - 10 micron range. Most plastics and many other materials absorb infrared best in this range, which makes the ceramic heater the most efficient infrared radiant emitter on the market. A range of aluminised steel reflectors are also available to ensure that most of the radiation generated is reflected forward on to the target area. Applications Ceramic infrared elements are used in a diverse range of industrial processes such as: Heating l Thermoforming l Heat treatment on fabric l Sealing Feeding leads l Metal sheet folding Drying l Paint/ glue curing l Printing Mounting turret l Lacquering and other surface treatments for wood l Glazing of ceramics Special ceramic Oven for l Dust painting l Teflon coating l Coachwork repairs (paint) l Printing Resistive winding Ceramic elements are also very effectively in infrared outdoor heaters and infrared saunas Advantages in using infrared ceramic heaters l Fast heat transmission l Radiation constant over time l Uniform heating l Durability l long lasting surface – anti corrosion-anti-spray Thermocouple l Easy to install For further information please contact our technical dep.

Quartz tungsten elements Technical features Quartz halogen/tungsten elements general features Ceramicx Ireland produces extremely penetrative infrared heaters (infrared emitters) using two types of tungsten filaments: the porcupine or star type filament for fast medium wave emitters, and the supported filament for short wave halogen emitters. The emitters heat up and cool down within seconds making them particularly suitable for systems requiring short cycle times. Fast Medium Wave Quartz Tungsten Heaters Technical features general features The tungsten filament used in these heaters is the porcupine or star type coil, which can be operated at temperatures up to 1500°C (2732°F), with peak wavelength emissions of approximately 1.6 microns. It reaches top temperatures within seconds. As well as having excellent structural rigidity, this coil is designed to minimize light output and maximize IR emission thereby increasing IR radiant efficiency.

Accessories for infrared heating Accessories for infrared heating Ceramic Terminal Blocks Wave Spring and Clip E27 Ceramic Bulb Holder Buzz Bars V-Clips Ceramic Bulb Reflector 28 High temperature ceramic terminal blocks. They are used with buzz bars to produce power distribution systems. Used in the mounting and installation of all Ceramic elements and the PFQE element. Included with these heaters as standard. One piece spring/clip also available High temperature porcelain holder used in operation of ceramic IR bulbs. Buzz Bars (Dimensions: 8 mm x 2 mm) can be used with the ceramic terminal block to produce a flexible and maintenance free power distribution system Can be used to connect power leads to buzz bar distribution systems in combination with a fixing screw (supplied) Highly polished reflector for use with ceramic IR bulbs. R7s Holders The Ceramic R7s holder is used for mounting of heaters with the R7s termination. Max temperature: 350°C (662°F) High temperature leads Up to 350°C Z.R.E. Accessories Technical features VLC20 measuring with static relays general features special instruments with 2 separate programmable control systems, phase angle and fast zero crossing with phase angle. Static relay and thermal fuse built in suitable for resistive load mono 230V 4KW as infrared heaters short and medium wave phase angle: soft start 200ms and auto soft start for temporary brown out l l fast zero crossing with pre heating : soft start with phase angle with maintaining for 5 sec then with switch to fast zero crossing with 400ms as cycle time NOTE: Soft start and fast zero crossing enable the operator to reduce the in – rush extracurrent during the start up and the cycle which may reduce the life spam of many components as short wave infrared elements. Furthermore they avoid any damage of the protection thermal fuse. How to set VLC20 To set VLC20 with phase angle or fast zero crossing please follow instructions below: Push DOWN button since the display value is 0 Keeping push DOWN push also UP button since the display shows a line, then F ( phase angle) then release or push DOWN again to P (zero crossing) Pushing DOWN is possible to switch from F to P To confirm push UP VLC20 restart automaticallywhen function are saved on E2prom Technical data l Feeding tension 230V AC/DC 2VA l Static relay 20A 230V AC 50hz l Internal thermal fuse 25AmpFF l General mechanical switch l Metal case with fairlead Control l Range 0-100% steps. l Set up saving on E2prom l Thermal fuse break warning ( on the display) Connection and internal therminal block L2 R TRAS.1 N 4KW 230V 50Hz Dimension 170 U Fairlead Ø 12mm M1 HEAT DISSIPATOR F1 FUSE. 25FF 6,3 x 32 150 NEUTRAL L1 CARICO LINE S1 VLC20 70 29 10040 San Gillio - Torino (Italy) - Via Druento, 48/2 Marcatura secondo direttiva 2006/95/CE del 11/12/2006 © Copyright Z.R.E. 20\0 - Rev 1.0 - All right reservedi Tel. +390119841848 8 linee R.A. - Fax +390119848099 e-mail: info@zre.it www.zre.it
